Adobe has issued an unscheduled update to correct flaws in Adobe Flash Player, including a zero-day vulnerability that is currently being exploited in the wild by an APT threat group on targets in Russia. One target was a Russian healthcare facility that provides medical and cosmetic surgery services to high level civil servants of the Russian Federation.
The zero-day flaw is a use-after-free vulnerability – CVE-2018-15982 – which allows arbitrary code execution and privilege execution in Flash Player. A malicious Flash object runs malicious code on a victim’s computer which gives command line access to the system.
The vulnerability was discovered by security researchers at Gigamon ATR who reported the flaw to Adobe on November 29. Researchers at Qihoo 360 identified a spear phishing campaign that is being used to deliver a malicious document and associated files that exploit the flaw. The document used in the campaign was a forged employee questionnaire.
The emails included a .rar compressed file attachment which contained a Word document, the vulnerability, and the payload. If the .rar file is unpacked and the document opened, the user is presented with a warning that the document may be harmful to the computer. If the content is enabled, a malicious command is executed which extracts and runs the payload – A Windows executable file named backup.exe that is disguised as an NVIDIA Control Panel application. Backup.exe serves as a backdoor into a system. The malicious payload collects system information which is sent back to the attackers via HTTP POST. The payload also downloads and executes shell code on the infected device.
Qihoo 360 researchers have named the campaign Operation Poison Needles due to the identified target being a healthcare clinic. While the attack appears to be politically motivated and highly targeted, now that details of the vulnerability have been released it is likely that other threat groups will use exploits for the vulnerability in more widespread attacks.
It is therefore important for businesses that have Flash Player installed on some of their devices to update to the latest version of the software as soon as possible. That said, uninstalling Flash Player, if it is not required, is a better option given the number of vulnerabilities that are discovered in the software each month.
The vulnerability is present in Flash Player 18.104.22.168 and all earlier versions. Adobe has corrected the flaw together with a DLL hijacking vulnerability in version 22.214.171.124.
A new module has been added to TrickBot malware that adds point-of-sale (POS) data collection capabilities.
TrickBot is a modular malware that is being actively developed. In early November, TrickBot was updated with a password stealing module, but the latest update has made it even more dangerous, especially for hotels, retail outlets, and restaurants: Businesses that process large volumes of card payments.
The new module was identified by security researchers at Trend Micro who note that, at present, the module is not being used to record POS data such as credit/debit card numbers. Currently, the new TrickBot malware module is only collecting data about whether an infected device is part of a network that supports POS services and the types of POS systems in use. The researchers have not yet determined how the POS information will be used, but it is highly likely that the module is being used for reconnaissance. Once targets with networks supporting POS systems have been identified, they will likely be subjected to further intrusions.
The new module, named psfin32, is similar to a previous network domain harvesting module, but has been developed specifically to identify POS-related terms from domain controllers and basic accounts. The module achieves this by using LDAP queries to Active Directory Services which search for a dnsHostName that contains strings such as ‘pos’, ‘retail’, ‘store’, ‘micros’, ‘cash’, ‘reg’, ‘aloha’, ‘lane’, ‘boh’, and ‘term.’
The timing of the update, so close to the holiday period, suggests the threat actors are planning to take advantage of the increase in holiday trade and are gathering as much information as possible before the module is used to harvest POS data.
The recent updates to TrickBot malware have been accompanied by a malicious spam email campaign (identified by Brad Duncan) which is targeting businesses in the United States. The malspam campaign uses Word documents containing malicious macros that download the TrickBot binary.
Protecting against TrickBot and other information stealing malware requires a defense-in-depth approach to cybersecurity. The main attack vector used by the threat actors behind TrickBot is spam email, so it is essential for an advanced anti-spam solution to be deployed to prevent malicious messages from being delivered to end users’ inboxes. End user training is also essential to ensure employees are made aware of the danger of opening emails from unknown senders, launching suspicious email attachments, and clicking hyperlinks in those messages.
Antivirus solutions and endpoint security controls should also be deployed to identify and quarantine potentially malicious files in case malware makes it past perimeter defenses.
There is a more cost-effective alternative to Cisco OpenDNS that provides total protection against web-based threats at a fraction of the price of OpenDNS. If you are currently running OpenDNS or have yet to implement a web filtering solution, you can find out about this powerful web filtering solution in a December 5, 2018 webinar.
Cybersecurity defenses can be implemented to secure the network perimeter, but employees often take risks online that can lead to costly data breaches. The online activities of employees can easily result in malware, ransomware, and viruses being downloaded. Employees may also respond to malicious adverts (malvertising) or visit phishing websites where they are relieved of their login credentials.
Mitigating malware infections, dealing with ransomware attacks, and resolving phishing-related breaches have a negative impact on the business and the resultant data breaches can be incredibly costly. Consequently, the threat from web-based attacks cannot be ignored.
Fortunately, there is an easy solution that offers protection against web-based threats by carefully controlling the web content that their employees can access: A DNS-based web filter.
DNS-based web filtering requires no hardware purchases and no software downloads. Within around 5 minutes, a business will be able to control employee internet access and block web-based threats. Some DNS-based web filters such as OpenDNS can be costly, but there is a more cost-effective alternative to Cisco OpenDNS.
TitanHQ and Celestix Networks will be running a joint webinar to introduce an alternative to Cisco OpenDNS – The WebTitan-powered solution, Celestix WebFilter Cloud.
Celestix will be joined by Rocco Donnino, TitanHQ EVP of Strategic Alliances, and Senior Sales Engineer, Derek Higgins who will explain how the DNS-based filtering technology offers total protection from web-based threats at a fraction of the cost of OpenDNS.
The webinar will be taking place on Wednesday December 5, 2018 at 10:00 AM US Pacific Time
An email archiving solution is now a requirement in business to ensure that emails are not lost, storage space is kept to a minimum, and emails can be retrieved on demand. While native Microsoft Exchange Email Archiving is available, many businesses will find the archiving options come up short. The alternative is to use a third-party email archiving solution. Not only will this provide all the features required by businesses, it will improve efficiency and will save on cost. To meet the requirements of businesses and improve efficiency, TitanHQ developed ArcTitan: A secure, fast, cloud-based email archiving solution.
What is Email Archiving and Why is it Important?
Federal, state, and industry regulations require businesses to retain emails for many years. Storing emails can take up a considerable amount of storage space, especially considering the volume of emails that are typically sent and received on a daily basis by employees. While businesses can get away with storing emails in backups to meet legal requirements, backups are not searchable. If emails need to be recovered, they need to be recovered quickly. That is simply not possible with backups as they are not searchable. The solution is an email archive. In contrast to backups, email archives are searchable, and messages can be retrieved on-demand quickly and with minimal effort.
Email Archiving is Essential for eDiscovery and GDPR Compliance
The importance of an email archiving solutions for eDiscovery cannot be underestimated. There have been many cases where businesses have received heavy fines for the failure to produce emails as part of the eDiscovery process. For instance, in the Zubulake v. USB Warburg case, the plaintiff was awarded $29 million as a result of the failure to produce emails. In Coleman Holdings v. Morgan Stanley, eDiscovery failures resulted in a fine of $15 million.
Email archives are now essential for GDPR compliance. Sine the EU’s General Data Protection Regulation came into effect on May 25, 2018, companies have been required to produce – and delete – on request every element of an individual’s personal data, including personal data contained in emails. Without an email archive, this can be incredibly time consuming and may result in data being unlawfully retained since backups are not searchable. The fines for GDPR compliance failures can be as high as €20 million or 4% of global annual revenue, whichever is greater.
Native Microsoft Exchange Email Archiving
Native Microsoft exchange email archiving provides businesses with journaling and personal archive functions, but each has its drawbacks. The functions meet some business requirements, such as freeing up space in mailboxes, but they lack the full functions of a dedicated archive and do not meet all eDiscovery requirements.
Wirth native Microsoft Exchange email archiving, end users have far too much control over the information that is loaded into an archive and they can delete emails unless a legal hold is activated. For admins, the control panel is difficult to use and retrieving emails can be complicated and time consuming.
Native Microsoft Exchange email archiving functions fail to meet the needs of many businesses, especially those in highly regulated industries. While the native Microsoft Exchange email archiving functions have improved over the years, there are limitations with most product versions and archiving can be complex with certain email architectures.
Any business that uses multiple email systems alongside Microsoft Exchange will require a third-party email archiving solution. Microsoft Exchange does not support the archiving of email from other platforms.
Email archiving has improved with Office 365. SMBs that use Office 365 have email archiving functionality included in their plans, but it is only free of charge with E3-E5 plans. Other plans charge around $3 per user, which is more expensive than custom-built archiving solutions such as ArcTitan.
Native Microsoft Exchange email archiving is an option for businesses, but Microsoft Exchange was not developed for email archiving. A third-party solution for email archiving on Microsoft Exchange is still a requirement, despite the improvements that have been made by Microsoft.
A third-party email archiving solution will save your IT department a considerable amount of time trying to locate old messages, especially for the typical requests that are received which are light on detail. The advanced search options in ArcTitan make search and retrieval of messages much faster and easier.
Feature-Rich, Lightning Fast Email Archiving with ArcTitan
ArcTitan has been developed specifically for email archiving and email archiving alone. ArcTitan has been designed to meet all archiving needs of businesses and allow managed service providers to offer email archiving to their clients.
The benefits of ArcTitan include lighting fast email archiving and message retrieval, secure encrypted storage, and compliance with industry regulations such as HIPAA, SOX, SEC, FINRA, and GDPR. ArcTitan ensures businesses meet eDiscovery requirements without having to pay for additional eDiscovery services from Microsoft.
With ArcTitan, an accurate audit trail is maintained, and businesses have near instant access to all company emails. ArcTitan serves as a black box recorder for all email to meet all eDiscovery requirements and ensures compliance with federal, state, and industry regulations.
ArcTitan requires no hardware or software, is quick and easy to install, and easily slots in to the email architecture of businesses. The solution is highly scalable (there are no limits on storage space or users), it is lightning fast, easy to use, and stores all emails safely and securely.
Businesses that have yet to implement a Microsoft Exchange email archiving solution typically save up to 75% storage space and costs are kept to a minimum with a flexible pay as you go pricing policy, with subscriptions paid per live user.
If you have yet to implement an email archiving solution, if you are unhappy with the native Microsoft Exchange email archiving features, or find your current archiving solution expensive or difficult to use, get in touch with TitanHQ today to find out more about the benefits of ArcTitan and the improvements it can make to your business.
There has been a steady increase in HTTPS phishing websites over the past couple of years, mirroring the transition from HTTP to HTTPS on commercial websites. HTTPS sites are those that have SSL/TLS certificates and display a green padlock next to the URL. The green padlock is an indicator of site security. It confirms to website visitors that the connection between their browser and the website is encrypted. This provides protection against man-in-the-middle attacks by ensuring data sent from the browser to the website cannot be intercepted and viewed by third parties.
HTTPS websites are now used by a large number of businesses, especially e-commerce website owners. This has become increasingly important since search engines such as Google Chrome provide clear indications to Internet users that sites may not be secure if the connection is not encrypted.
This is all good of course, but there is one caveat. Users have been told to look for the green padlock to make sure a site is secure, but the green padlock is viewed by many Internet users as a sign that the site is secure and legitimate. While the former is true, the latter is not. The green padlock does not mean that the site is genuine and just because it is displayed next to the URL it does not mean the site is safe.
If the website is controlled by a cybercriminal, all the green padlock means is that other cybercriminals will not be able to intercept data. Any information entered on the website will be divulged to the criminal operating that site.
It stands to reason for HTTPS phishing websites to be used. If Internet users are aware that HTTPS means insecure, they will be less likely to enter sensitive information if the green padlock is not present. Unfortunately, free SSL certificates can easily be obtained to turn HTTP sites into HTTPS phishing websites.
According to PhishLabs, back in Q1, 2016, fewer than 5% of phishing websites used HTTPS. By Q3, 2016, the percentage started to rise sharply. By Q1, 2017, the percentage had almost reached 10%, and by Q3, 2017, a quarter of phishing websites were using HTTPS. The 30% milestone was passed around Q1, 2018, and at the end of Q3, 2018, 49% of all phishing sites were using HTTPS.
A PhishLabs survey conducted late last year clearly highlighted the lack of understanding of the meaning of the green padlock. 63% of consumers surveyed viewed the green padlock as meaning the website was legitimate, and 72% saw the website as being safe. Only 18% of respondents correctly identified the green padlock as only meaning communications with the website were encrypted.
It is important for all Internet users to understand that HTTPS phishing websites not only exist, but before long the majority of phishing websites will be on HTTPS and displaying the green padlock. A conversation about the true meaning of HTTPS is long overdue and it is certainly something that should be covered in security awareness training sessions.
It is also now important for businesses to deploy a web filtering solution that is capable of SSL inspection – The decryption, scanning, and re-encryption of HTTPS traffic to ensure that access to these malicious websites is blocked. In addition to reading content and assessing websites to determine whether they are malicious, SSL inspection ensures site content can be categorized correctly. This ensures that sites that violate a company’s acceptable usage policies are blocked.
There is a downside to using SSL inspection, and that is the strain placed on CPUs and a reduction in Internet speeds. SSL inspection is therefore optional with many advanced web filters. To ensure that the strain is reduced, IT teams should use whitelisting to prevent commonly used websites from being subjected to SSL filtering.
WebTitan Includes SSL Filtering to Block HTTPS Phishing Websites
WebTitan is a powerful web filtering solution for SMBs and managed service providers (MSPs) that provides protection against web-based threats. There are three products in the WebTitan family – WebTitan Gateway, WebTitan Cloud, and WebTitan Cloud for Wi-Fi; all of which include SSL filtering as standard. If SSL filtering is activated, users will be protected against HTTPS phishing websites and other malicious sites that have SSL certificates.
All WebTitan products can be installed in minutes, require no technical knowledge, and have been designed to be easy to use. An intuitive user interface places all information, settings, and reports at users’ fingertips which makes for easy enforcement of acceptable Internet usage polices and fast reporting to identify potential issues – employees browsing habits and users that are attempting to bypass filtering controls for instance.
Whether you are an MSP that wants to start offering web filtering to your clients or a SMB owner that wants greater protection against web-based threats, the WebTitan suite of products will provide all the features you need and will allow you to improve security and employee productivity, reduce legal liability, and create a safe browsing environment for all users of your wired and wireless networks.

A California wildfire scam is circulating that requests donations to help the victims of the recent wildfires. The emails appear to come from the CEO of a company and are directed at its employees in the accounts and finance department.
It should come as no surprise that cybercriminals are taking advantage of yet another natural disaster and are attempting to con people into giving donations. Scammers often take advantage of natural disasters to pull on the heart strings and defraud businesses. Similar scams were conducted in the wake of the recent hurricanes that hit the United States and caused widespread damage.
The California wildfire scam, identified by Agari, is a form of business email compromise (BEC) attack. The emails appear to have been sent by the CEO of a company, with his/her email address used to send messages to company employees. This is often achieved by spoofing the email address although in some cases the CEO’s email account has been compromised and is used to send the messages.
The California wildfire scam contains one major red flag. Instead of asking for a monetary donation, the scammers request money in the form of Google play gift cards. The messages request the redemption codes be sent back to the CEO by return.
The emails are sent to employees in the accounts and finance departments and the emails request that the money be sent in 4 x $500 denomination gift cards. If these are sent back to the CEO, he/she will then forward them on to company clients that have been affected by the California wildfires.
The reason Google play gift cards are requested is because they can easily be exchanged on darknet forums for other currencies. The gift cards are virtually impossible to trace back to the scammer.
The messages are full of grammatical errors and spelling mistakes. Even so, it is another sign that the messages are not genuine. However, scams such as this are sent because they work. Many people have been fooled by similar scams in the past.
Protecting against scams such as this requires a combination of technical controls, end user training, and company policies. An advanced spam filtering solution should be used – SpamTitan for instance – to prevent messages such as these from reaching inboxes. SpamTitan checks all incoming emails for spam signatures and uses advanced techniques such as heuristics, machine learning, and Bayesian analysis to identify advanced and never-before-seen phishing attacks.
End user training is essential for all employees, especially those with access to corporate bank accounts. Those individuals are often targeted by scammers. Policies should be introduced that require all requests for changes to bank accounts, atypical payment requests, and wire transfers above a certain threshold to be confirmed by phone or in person before they are authorized.
A combination of these measures will help to protect businesses from BEC attacks and other email scams.
A previously unseen malware variant, dubbed the Cannon Trojan, is being used in targeted attacks on government agencies in the United States and Europe. The new malware threat has been strongly linked to a threat group known under many names – APT28, Fancy Bear, Sofacy, Sednet, Strontium – that has links to the Russian government.
The Cannon Trojan is being used to gather information on potential targets, collecting system information and taking screenshots that are sent back to APT28. The Cannon Trojan is also a downloader capable of installing further malware variants onto a compromised system.
The new malware threat is stealthy and uses a variety of tricks to avoid detection and hide communications with its C2. Rather than communicating over HTTP/HTTPS, like other malware variants used by APT28, the Cannon Trojan communicates via email over SMTPs and POP3S.
Once installed, an email is sent over SMTPS through port 465 and a further two email addresses are obtained through which the malware communicates with its C2 using the POP3S protocol to receive instructions and send back data. While the use of email for communicating with a C2 is not unknown, it is relatively rare. One advantage offered by this method of communication is it is more difficult to identify and block that HTTP/HTTPS.
The Cannon Trojan, like the Zebrocy Trojan which is also being used by APT28, is being distributed via spear phishing emails. Two email templates have been intercepted by Palo Alto Networks’ Unit 42 team, one of which takes advantage of interest in the Lion Air plane crash in Indonesia.
The Lion Air spear phishing campaign appears to provide information on the victims of the crash, which the email claims are detailed in an attached Word document titled Crash List (Lion Air Boeing 737).docx. The user must Enable Content to view the contents of the document. It is claimed that the document was created in an earlier version of Word and content must be enabled for the file to be displayed. Opening the email and enabling content would trigger the macro to run, which would then silently download the Cannon Trojan.
Rather than the macro running and downloading the payload straightaway, as an anti-analysis mechanism, the attackers use the Windows AutoClose tool to delay completion of the macro routine until the document is closed. Only then is the Trojan downloaded. Any sandbox that analyzes the document and exits before closing the document would be unlikely to identify it as malicious. Further, the macro will only run if a connection with the C2 is established. Even if the document is opened and content is enabled, the macro will not run without its C2 channel open.
The techniques used by the attackers to obfuscate the macro and hide communications make this threat difficult to detect. The key to preventing infection is blocking the threat at source and preventing it from reaching inboxes. The provision of end user training to help employees identify threats such as emails with attachments from unknown senders is also important.
Enhance Protection Against Zero-Day Malware and Spear Phishing
TitanHQ has developed a powerful anti-phishing and anti-spam solution that is effective at blocking advanced persistent threats and zero-day malware, which does not rely on signature-based detection methods. While dual anti-virus engines offer protection against 100% of known malware, unlike many other spam filtering solutions, SpamTitan uses a variant of predictive techniques to identify previously unseen threats and spear phishing attacks.
Greylisting is used to identify domains used for spamming that have yet to be blacklisted. All incoming emails are subjected to Bayesian analysis, and heuristics are used to identify new threats.
To further protect against phishing attacks, URIBL and SURBL protocols are used to scan embedded hyperlinks. SpamTitan also scans outbound mail to prevent abuse and identify attempted data theft.

There has been an increase in malspam campaigns spreading Emotet malware in recent weeks, with several new campaigns launched that spoof financial institutions – the modus operandi of the threat group behind the campaigns.
The Emotet malware campaigns use Word documents containing malicious macros. If macros are enabled, the Emotet malware payload is downloaded. The Word documents are either sent as email attachments or the spam emails contain hyperlinks which direct users to a website where the Word document is downloaded.
Various social engineering tricks have been used in these campaigns. One new tactic that was identified by Cofense is the wrapping of malicious hyperlinks in Proofpoint’s (PFPT) TAP URL Defense wrapping service to make the email appear benign.
According to Cofense, the campaign delivers Emotet malware, although Emotet in turn downloads a secondary payload. In past campaigns, Emotet has been delivered along with ransomware. First, Emotet steals credentials, then the ransomware is used to extort money from victims. In the latest campaign, the secondary malware is the banking Trojan named IcedID.
A further campaign has been detected that uses Thanksgiving themed spam emails. The messages appear to be Thanksgiving greetings for employees, and similarly contain a malicious hyperlink or document. The messages claim the document is a Thanksgiving card or greeting. Many of the emails have been personalized to aid the deception and include the user’s name. In this campaign, while the document downloaded appears to be a Word file, it is actually an XML file.
Emotet malware has been updated recently. In addition to stealing credentials, a new module has been added that harvests emails from an infected user. The previous 6 months’ emails – which include subjects, senders, and message content – are stolen. This new module is believed to have been added to improve the effectiveness of future phishing campaigns, for corporate espionage, and data theft.
The recent increase in Emotet malware campaigns, and the highly varied tactics used by the threat actors behind these campaigns, highlight the importance of adopting a defense in depth strategy to block phishing emails. Organizations should not rely on one cybersecurity solution to provide protection against email attacks.
Phishing campaigns target a weak link in security defenses: Employees. It is therefore important to ensure that all employees with corporate email accounts are taught how to recognize phishing threats. Training needs to be ongoing and should cover the latest tactics used by cybercriminals to spread malware and steal credentials. Employees are the last line of defense. Through security awareness training, the defensive line can be significantly strengthened.
As a frontline defense, all businesses and organizations should deploy an advanced spam filtering solution. While Office 365 email includes a basic level of protection against phishing attacks, a powerful third-party anti-phishing and spam filtering solution is required to provide protection against more sophisticated email attacks.
SpamTitan is an advanced email filtering solution that uses predictive techniques to provide superior protection against phishing attacks, zero-day attacks, and new malware variants that bypass signature-based defenses.
In addition to scanning message content, headers, attachments, and hyperlinks for spam and malware signatures, SpamTitan uses heuristics, machine learning, and Bayesian analysis to identify emerging threats. Greylisting is used to identify and block large scale spam campaigns, such as those typically conducted by the threat actors spreading banking Trojans and Emotet malware.
How SpamTitan Protects Businesses from Email Threats
A web filter – such as WebTitan – adds an additional layer of protection against web-based attacks by preventing end users from visiting malicious websites where malware is downloaded. A web filter assesses all attempts to access web content, checks sites against blacklists, assesses the domain, scans web content, and blocks access to sites that violate its policies.
For further information on how you can improve your defenses against web-based and email-based attacks and block malware, ransomware, botnets, viruses, phishing, and spear phishing attacks, contact TitanHQ today.
Office 365 has many benefits, so it is no surprise that it is proving so popular with businesses, but one common complaint is the number of spam and malicious emails that sneak past Microsoft’s defenses. If you have a problem with spam and phishing emails, there is an easy solution to improve the Office 365 spam filter.
Office 365 Email Protection
More than 135 million commercial users are now on Office 365. Unfortunately, the popularity of Office 365 has made it a target for hackers. Microsoft has been proactively taking steps to improve the Office 365 spam filter to make it more effective at blocking spam and phishing attempts. Office 365 phishing protections have been improved and more malicious emails are now being blocked; however, even with the recent anti-phish enhancements, many businesses still have to deal with spam, phishing emails, and other malicious messages.
Businesses using Office 365 as a hosted email solution are likely to have their email filtered using Exchange Online protection or EOP. EOP does provide a decent level of protection and blocks spam, phishing emails, and malware. Osterman Research confirmed that EOP eliminates 100% of known malware and blocks 99% of spam email but struggles with the last 1%. Many businesses have found that EOP blocks basic phishing attacks but comes up short at blocking more advanced email threats such as spear phishing and advanced persistent threats.
To improve the Office 365 spam filter, it is necessary to upgrade to Advanced Threat Protection, the second level of protection offered with Office 365. The level of protection is much better, although Advanced Threat Protection cannot identify zero-day threats and falls short of many third-party solutions on blocking other advanced threats. A SE Labs study in the summer of 2017 found that even with the additional level of protection, which is only available in the Office 365 E5 license tier, protection only ranked in the low-middle of the market.
The number of cases of hackers exploiting vulnerabilities in Office 365 and the volume of direct attacks on Office 365 users has seen an increasing number of businesses looking for a way to improve the Office 365 spam filter further.
An Easy Way to Improve the Office 365 Spam Filter
Businesses that want to further improve the Office 365 spam filter (and those looking for an Office 365 Advanced Threat Protection alternative) need to consider implementing a third-party anti-spam solution.
Fortunately, there is a solution that will not only improve Office 365 spam filtering, it is quick and easy to implement, requires no software downloads, and no hardware purchases are necessary. In fact, it can be implemented, configured, and be up and running in a few minutes.
SpamTitan is a powerful cloud-based email security solution that has been developed to provide superior protection against spam, phishing, malware, zero-day attacks, and data loss via email.
In contrast to Office 365, SpamTitan uses predictive techniques such as Bayesian analysis, machine learning, and heuristics to block zero-day attacks, advanced persistent threats, new malware variants, and new spear phishing methods.
SpamTitan searches email headers, analyzes domains, and scans email content to identify phishing threats. Embedded hyperlinks, including shortened URLs, are scanned in real time and subjected to URL multiple reputation checks, while dual antivirus engines scan and block 100% of known malware.
SpamTitan also incorporates data loss prevention tools for emails and attachments, which are not available with EOP. Users can create tags for keywords and data elements such as Social Security numbers to protect against theft by insiders. SpamTitan also serves as a backup for your mail server to ensure business continuity.
With SpamTitan you get a greater level of protection against spam and malicious emails, a higher spam catch rate (over 99.9%), greater granularity, improved control over outbound email, and better business continuity protections.
If you have transitioned to Office 365 yet are still having problems with spam, phishing, and other malicious emails or if you are an MSP that wants to offer clients enhanced Office 365 email security, contact the TitanHQ team today.
The TitanHQ team will be happy to schedule a product demonstration and help you put SpamTitan through the paces in your own environment in a no-obligation free trial.
Reselling Office 365 doesn’t offer much in the way of profit for MSPs, although there are benefits for MSPs that come from offering Office 365 and it is possible to make Office 365 more profitable.
Before explaining where the margin is for MSPs in Office 365, let’s first take a look at the benefits for MSPs from offering Office 365.
Benefits for MSPs from Offering Office 365 to Clients
SMBs are increasingly moving from on-premises solutions to the cloud and Office 365 is one of the most popular cloud services. Office 365 now has more than 135 million commercial monthly users and that number is growing rapidly.
MSPs may not be able to make much from Office 365 alone, but by providing Office 365 MSPs can win more business and gain a competitive advantage. There is no outlay involved with offering Office 365 to clients, the product is great and meets clients’ needs, and money can be made from handling Office 365 migrations.
MSPs can also benefit from migrating existing clients from Exchange or SBS Exchange to Office 365. Office 365 is far easier to manage so they stand to save a great deal of time on troubleshooting and maintenance, which can be a major headache with Exchange.
By offering Office 365 you can win more business, reduce operational costs, and stay competitive. However, the best way to make money from Office 365 is through add-on services.
How MSPs Can Make Office 365 More Profitable
The margins for MSPs on Office 365 are rather thin to say the least. Many MSPs find that offering Office 365 on its own doesn’t provide any profit at all. Charging extra per license to improve profitability is an option, but clients could just go direct to avoid the extra cost.
The margins may be small, but managing Office 365 does not require a great deal of effort. You may only make around 50c or $1 per user but sign up enough clients and you could get a reasonable return. There is an opportunity for profit at scale; however, to make a decent return you need to sell services around Office 365.
One of the best ways to make Office 365 more profitable is by offering additional security services. Security is an area where Office 365 can be significantly improved, especially spam filtering. Microsoft has incorporated a spam filter and anti-phishing protections into Office 365, but they fall short of the protection offered by a dedicated third-party spam filter.
Phishing is the number one security threat faced by businesses and Office 365 anti-phishing protections leave a lot to be desired. By offering enhanced spam and phishing protection through a third-party spam filter, not only can MSPs make a decent margin on the add-on solution, by blocking phishing attacks and malware at source, a considerable amount of time can be saved on support.
There are plenty of other opportunities for selling third-party solutions to make up for the lack of options in Office 365. Email archiving is an easy sell and a quick win for MSPs. An email archive is important for compliance and security, saves on storage space, and improves efficiency, and gives clients access to emails from any location.
Spam filtering, email archiving, web filtering, and encryption can be bundled together as an enhanced security package, with each element providing a decent return for MSPs. Given the cost of mitigating a data breach, by preventing breaches, an enhanced security offering will pay for itself. Consequently, Office 365 security should be an easy sell.

Email archiving for MSPs is an often-overlooked service that can add value and improve profits. Email archiving is easy to implement and manage, has a high margin, generates regular additional income, and is an easy sell to clients.
In this post we explore the benefits for clients and MSPs and explain why email archiving for MSPs and their clients is a win-win.
Benefits of Email Archiving for SMBs
Email archiving is now important for organizations of all sizes, from SMBs to the largest enterprises. Huge volumes of emails are sent and received on a daily basis and copies of those emails need to be stored, saved, and often retrieved. Storage of emails in mailboxes poses problems. The storage space required for emails and attachments can be considerable, which means hardware must be purchased and maintained. In terms of security, storing large volumes of emails in mailboxes is never a good idea.
Storing emails in backups is an option, although it is far from ideal. Space is still required and recovering emails when they are needed is a major headache as backup files are not indexed and searching for messages can be extremely time consuming.
An email archive on the other hand is indexed and searchable and emails can be quickly and easily retrieved on demand. If there is a legal dispute or when an organization needs to demonstrate compliance – with GDPR or HIPAA for example – businesses need to be able to recover emails quickly and easily. An email archive also provides a clear chain of custody, which is also required for compliance with many regulations.
Cloud-based archives offer secure storage for emails with no restrictions on storage space. Cloud storage is highly scalable and emails can be easily retrieved from any location.
In short, email archiving can improve efficiency, enhance security, lower costs, and is an invaluable compliance tool.
Benefits of Email Archiving for MSPs
Given the benefits of email archiving it should be an easy sell for MSPs, either as Office 365 archiving-as-a-service as an add-on or incorporated into existing email packages to offer greater value and make your packages stand out from those of your competitors.
As an add-on service, Office 365 archiving-as-a-service will generate regular income for very little effort and will improve the meagre returns from simply offering Office 365 to your clients. As part of a package it can help you to attract more business.

A new Dharma ransomware variant has been developed that is currently evading detection by the majority of antivirus engines. According to Heimdal Security, the latest Dharma ransomware variant captured by its researchers was only detected as malware by one of the 53 AV engines on VirusTotal.
Dharma ransomware (also known as CrySiS) first appeared in 2006 and is still being developed. This year, several new Dharma ransomware variants have been released, each using new file extensions for encrypted files (.bip, .xxxxx, .like, java, .arrow, .gamma, .arena, .betta, and .tron to name but a few). In the past two months alone four new Dharma ransomware variants have been detected.
The threat actors behind Dharma ransomware have claimed many victims in recent months. Successful attacks have been reported recently by Altus Baytown Hospital in Texas, the Arran brewery in Scotland, and the port of San Diego.
While free decryptors for Dharma ransomware have been developed, the constant evolution of this ransomware threat rapidly renders these decryptors obsolete. Infection with the latest variants of the ransomware threat only give victims three options: pay a sizeable ransom to recover files, restore files from backups, or face permanent file loss.
The latter is not an option given the extent of files that are encrypted. Restoring files from backups is not always possible as Dharma ransomware can also encrypt backup files and can delete shadow copies. Payment of a ransom is not advised as there is no guarantee that files can or will be decrypted.
Protecting against ransomware attacks requires a combination of policies, procedures, and cybersecurity solutions. Dharma ransomware attacks are mostly conducted via two attack vectors: The exploitation of Remote Desktop protocol (RDP) and via email malspam campaigns.
The latest Dharma ransomware variant attacks involve an executable file being dropped by a .NET file and HTA file. Infections occur via RDP-enabled endpoints using brute force attempts to guess passwords. Once the password is obtained, the malicious payload is deployed.
While it is not exactly clear how the Arran brewery attack occurred, a phishing attack is suspected. Phishing emails had been received just before file encryption. “We cannot be 100 percent sure that this was the vector that infection occurred through, but the timing seems to be more than coincidental,” said Arran Brewery’s managing director Gerald Michaluk.
To protect against RDP attacks, RDP should be disabled unless it is absolutely necessary. If RDP is required, access should only be possible through a VPN and strong passwords should be set. Rate limiting on login attempts should be configured to block login attempts after a set number of failures.
Naturally, good backup policies are essential. They will ensure that file recovery is possible without payment of a ransom. Multiple copies of backups should be made with one copy stored securely off site.
To protect against email-based attacks, an advanced spam filter is required. Spam filters that rely on AV engines may not detect the latest ransomware variants. Advanced analyses of incoming messages are essential.
SpamTitan can improve protection for businesses through combination of two AV engines and predictive techniques to block new types of malware whose signatures have not yet been uploaded to AV engines.

Phishing is the number one security threat faced by businesses. In this post we explore why phishing is such as serious threat and the top phishing lures that are proving to be the most effective at getting employees to open malicious attachments and click on hyperlinks and visit phishing websites.
Phishing is the Biggest Security Threat Faced by Businesses
Phishing is a tried and tested social engineering technique that is favored by cybercriminals for one very simple reason. It is very effective. Phishing emails can be used to fool end users into installing malware or disclosing their login credentials. It is an easy way for hackers to gain a foothold in a network to conduct further cyberattacks on a business.
Phishing works because it targets the weakest link in security defenses: End users. If an email is delivered to an inbox, there is a relatively high probability that the email will be opened. Messages include a variety of cunning ploys to fool end users into taking a specific action such as opening a malicious email attachment or clicking on an embedded hyperlink.
Listed below are the top phishing lures of 2018 – The messages that have proven to be the most effective at getting end users to divulge sensitive information or install malware.
Top Phishing Lures of 2018
Determining the top phishing lures is not straightforward. Many organizations are required to publicly disclose data breaches to comply with industry regulations, but details of the phishing lures that have fooled employees are not usually made public.
Instead, the best way to determine the top phishing lures is to use data from security awareness training companies. These companies have developed platforms that businesses can use to run phishing simulation exercises. To obtain reliable data on the most effective phishing lures it is necessary to analyze huge volumes of data. Since these phishing simulation platforms are used to send millions of dummy phishing emails to employees and track responses, they are useful for determining the most effective phishing lures.
In the past few weeks, two security awareness training companies have published reports detailing the top phishing lures of 2018: Cofense and KnowBe4.
Top Phishing Lures on the Cofense Platform
Cofense has created two lists of the top phishing lures of 2018. One is based on the Cofense Intelligence platform which collects data on real phishing attacks and the second list is compiled from responses to phishing simulations.
Both lists are dominated by phishing attacks involving fake invoices. Seven out of the ten most effective phishing campaigns of 2018 mentioned invoice in the subject line. The other three were also finance related: Payment remittance, statement and payment. This stands to reason. The finance department is the primary target in phishing attacks on businesses.
The list of the top phishing lures from phishing simulations were also dominated by fake invoices, which outnumbered the second most clicked phishing lure by 2 to 1.
Number of Reported Emails
New Message in Mailbox
Online Order (Attachment)
Secure Message (MS Office Macro)
Online Order (Hyperlink)
Confidential Scanned document (Attachment)
Conversational Wire transfer (BEC Scam)
Top Phishing Lures on the KnowBe4 Platform
KnowBe4 has released two lists of the top phishing lures of Q3, 2018, which were compiled from responses to simulated phishing emails and real-world phishing attempted on businesses that were reported to IT security departments.
The most common real-world phishing attacks in Q3 were:
You have a new encrypted message
IT: Syncing Error – Returned incoming messages
HR: Contact information
FedEx: Sorry we missed you.
Microsoft: Multiple log in attempts
IT: IMPORTANT – NEW SERVER BACKUP
Wells Fargo: Irregular Activities Detected on Your Credit Card
LinkedIn: Your account is at risk!
Microsoft/Office 365: [Reminder]: your secured message
Coinbase: Your cryptocurrency wallet: Two-factor settings changed
The most commonly clicked phishing lures in Q3 were:
% of Emails Clicked
Password Check Required Immediately
You Have a New Voicemail

Change of Password Required Immediately
De-activation of [[email]] in Process
UPS Label Delivery 1ZBE312TNY00015011
Revised Vacation & Sick Time Policy
You’ve received a Document for Signature
Spam Notification: 1 New Messages
[ACTION REQUIRED] – Potential Acceptable Use Violation
The Importance of Blocking Phishing Attacks at their Source
If login credentials to email accounts, Office 365, Dropbox, and other cloud services are obtained by cybercriminals, the accounts can be plundered. Sensitive information can be stolen and Office 365/email accounts can be used for further phishing attacks on other employees. If malware is installed, cybercriminals can gain full control of infected devices. The cost of mitigating these attacks is considerable and a successful phishing attack can seriously damage a company’s reputation.
Due to the harm that can be caused by phishing, it is essential for businesses of all sizes to train staff how to identify phishing threats and implement a system that allows suspicious emails to be reported to security teams quickly. Resilience to phishing attacks can be greatly improved with an effective training program and phishing email simulations. It is also essential to deploy an effective email security solution that blocks threats and ensures they are not delivered to inboxes.
SpamTitan is a highly effective, easy to implement email filtering solution that blocks more than 99.9% of spam and phishing emails and 100% of known malware through dual anti-virus engines (Bitdefender and ClamAV). With SpamTitan protecting inboxes, businesses are less reliant on their employees’ ability to identify phishing threats.
SpamTitan subjects each incoming email to a barrage of checks to determine if a message is genuine and should be delivered or is potentially malicious and should be blocked. SpamTitan also performs checks on outbound emails to ensure that in the event that an email account is compromised, it cannot be used to end spam and phishing emails internally and to clients and contacts, thus helping to protect the reputation of the business.
Improve Office 365 Email Security with SpamTitan
There are more than 135 million subscribers to Office 365, and such high numbers make Office 365 a big target for cybercriminals. One of the main ways that Office 365 credentials are obtained is through phishing. Emails are crafted to bypass Office 365 defenses and hyperlinks are used to direct end users to fake Office 365 login pages where credentials are harvested.
Businesses that have adopted Office 365 are likely to still see a significant number of malicious emails delivered to inboxes. To enhance Office 365 security, a third-party email filtering control is required. If SpamTitan is installed on top of Office 365, a higher percentage of phishing emails and other email threats can be blocked at source.
To find out more about SpamTitan, including details of pricing and to register for a free trial, contact the TitanHQ team today. During the free trial you will discover just how much better SpamTitan is at blocking phishing attacks than standard Office 365 anti-spam controls.
A new Office 365 threat has been detected that stealthily installs malware by hiding communications and downloads by abusing legitimate Windows components.
New Office 365 Threat Uses Legitimate Windows Files to Hide Malicious Activity
The attack starts with malspam containing a malicious link embedded in an email. Various themes could be used to entice users into clicking the link, although one recent campaign masquerades as emails from the national postal service in Brazil.
The emails claim the postal service attempted to deliver a package, but the delivery failed as there was no one in. The tracking code for the package is included in the email and the user is requested to click the link in the email to receive the tracking information.
In this case, clicking the link will trigger a popup asking the user to confirm the download of a zip file, which it is alleged contains the tracking information. If the zip file is extracted, the user is required to click on a LNK file to receive the information. The LNK file runs cmd.exe, which executes a Windows Management Instrumentation (WMI) file: wmic.exe. This legitimate Windows file will be used to communicate with the attacker’s C2 server and will create a copy of another Windows file – certutil.exe in the %temp% folder with the name certis.exe. A script then runs which instructs the certis.exe file to connect to a different C2 server to download malicious files.
The aim of this attack is to use legitimate Windows files to download the malicious payload: A banking Trojan. The use of legitimate Windows files for communication and downloading files helps the attackers bypass security controls and install the malicious payload undetected.
These Windows files have the capability to download other files for legitimate purposes, so it is hard for security teams to identify malicious activity. This campaign targets users in Brazil, but this Office 365 threat should be a concern for all users as other threat actors have also adopted this tactic to install malware.
Due to the difficultly distinguishing between legitimate and malicious wmic.exe and certutil.exe activity, blocking an office 365 threat such as this is easiest at the initial point of attack: Preventing the malicious email from being delivered to an inbox and providing security awareness training to employees to help them identify this Office 365 threat. The latter is essential for all businesses. Employees can be turned into a strong last line of defense through security awareness training. The former can be achieved with a spam filtering solution such as SpamTitan. SpamTitan will prevent the last line of defense from being tested.
How to Block this Office 365 Threat with SpamTitan and Improve Email Security
Microsoft uses several techniques to identify malspam and prevent malicious messages from reaching users’ inboxes; however, while efforts have been made to improve the effectiveness of the spam filtering controls of Office 365, many malicious messages are still delivered.
To improve Office 365 security, a third-party spam filtering solution should be used. SpamTitan has been developed to allow easy integration into Office 365 and provides superior protection against a wide range of email threats.
SpamTitan uses a variety of methods to prevent malspam from being delivered to end users’ inboxes, including predictive techniques to identify threats that are misidentified by Office 365 security controls. These techniques ensure industry-leading catch rates in excess of 99.9% and prevent malicious emails from reaching inboxes.
How SpamTitan Protects Businesses from Email Threats
Security Solutions for MSPs to Block Office 365 Threats
Many MSPs resell Office 365 licenses to their customers. Office 365 allows MSPs to capture new business, but the margins are small. By offering additional services to enhance Office 365 security, MSPs can make their Office 365 offering more desirable to businesses while improving the profitability of Office 365.
TitanHQ has been developing innovative email and web security solutions for more than 25 years. Those solutions have been developed from the ground up with MSPs for MSPs. Three solutions are ideal for use with Office 365 for compliance ad to improve security – SpamTitan email filtering, WebTitan web filtering, and ArcTitan email archiving.
By incorporating these solutions into Office 365 packages, MSPs can provide clients with much greater value as well as significantly boosting the profitability of offering Office 365.
To find out more about each of these solutions, speak to TitanHQ. The MSP team will be happy to explain how the products work, how they can be implemented, and how they can boost margins on Office 365.
Financial institutions, healthcare organizations and universities have seen an increase in cyberattack in recent months, but there has also been an increase in phishing attacks on publishers and literary scouting agencies.
Any business that stores sensitive information that can be monetized is at risk of cyberattacks, and publishers and literary scouting agencies are no exception. Like any employer, scouting agencies and publishers store sensitive information such as bank account numbers, credit card details, Social Security numbers, contract information, and W-2 Tax forms, all of which carry a high value on the black market. The companies also regularly make wire transfers and are therefore targets for BEC scammers.
However, in a somewhat new development, there have been several reports of phishing attacks on publishers and literary scouting agencies that attempt to gain access to unpublished manuscripts and typescripts. These are naturally extremely valuable. If an advance copy of an eagerly awaited book can be obtained before it is published, there will be no shortage of fans willing to pay top dollar for a copy. Theft of manuscripts can result in extortion attempts with ransoms demanded to prevent their publication online.
2018 has seen a significant increase in phishing attacks on publishers and literary scouting agencies. Currently, campaigns are being conducted by scammers that appear to have a good understanding of the industry. Highly realistic and plausible emails are being to publishing houses and agencies which use the correct industry terminology, which suggests they are the work of an industry insider.
One current campaign is spoofing the email account of Catherine Eccles, owner of the international literary scouting agency Eccles Fisher. Emails are being sent using Catherine Eccles’ name, and include her signature and contact information. The messages come from what appears to be her genuine email account, although the email address has been spoofed and replies are directed to an alternative account controlled by the scammer. The messages attempt to get other literary agencies to send manuscripts via email or disclose their website passwords.
An increase in phishing attacks on publishers on both sides of the Atlantic have been reported, with the threat already having prompted Penguin Random House North America to send out warnings to employees to alert them to the threat. According to a recent report in The Bookseller, several publishers have been targeted with similar phishing schemes, including Penguin Random House UK and Pan Macmillan.
Protecting against phishing attacks requires a combination of technical solutions, policies and procedures, and employee training.
Publishers and scouting agencies should deploy software solutions that can block phishing attacks and prevent malicious emails from being delivered to their employees’ inboxes.
SpamTitan is a powerful anti-phishing tool that blocks 99.97% of spam emails and 100% of known malware. DMARC email-validation is incorporated to detect email spoofing and prevent malicious emails from reaching employees’ inboxes.
End user training is also essential to raise awareness of the risks of phishing. All staff should be trained how to recognize phishing emails and other email threats to ensure they do not fall for these email scams.
If you run a publishing house or literary scouting agency and are interested in improving your cyber defenses, contact the TitanHQ team today for further information on cybersecurity solutions that can improve your security posture against phishing and other email and web-based threats.
Hackers have been going back to school and entering higher education. Quite literally in fact, although not through conventional channels. Entry is gained through cyberattacks on universities, which have increased over the course of the past 12 months, according to figures recently released by Kaspersky Lab.
Cyberattacks on Universities on the Rise
Credit cards information can be sold for a few bucks, but universities have much more valuable information. As research organizations they have valuable proprietary data. The results of research studies are particularly valuable. It may not be possible to sell data as quickly as credit cards and Social Security numbers, but there are certainly buyers willing to pay top dollar for valuable research. Nation state sponsored hacking groups are targeting universities and independent hacking groups are getting in on the act and conducting cyberattacks on universities.
There are many potential attack vectors that can be used to gain access to university systems. Software vulnerabilities that have yet to be patched can be exploited, misconfigured cloud services such as unsecured S3 buckets can be accessed, and brute force attempts can be conducted to guess passwords. However, phishing attacks on universities are commonplace.
Phishing is often associated with scams to obtain credit card information or login credentials to Office 365 accounts, with businesses and healthcare organizations often targeted. Universities are also in the firing line and are being attacked.
The reason phishing is so popular is because it is often the easiest way to gain access to networks, or at least gain a foothold for further attacks. Universities are naturally careful about guarding their research and security controls are usually deployed accordingly. Phishing allows those controls to be bypassed relatively easily.
A successful phishing attack on a student may not prove to be particularly profitable, at least initially. However, once access to their email account is gained, it can be used for further phishing attacks on lecturers for example.
Spear phishing attacks on lecturers and research associates offer a more direct route. They are likely to have higher privileges and access to valuable research data. Their accounts are also likely to contain other interesting and useful information that can be used in a wide range of secondary attacks.
Email-based attacks can involve malicious attachments that deliver information stealing malware such as keyloggers, although many of the recent attacks have used links to fake university login pages. The login pages are exact copies of the genuine login pages used by universities, the only difference being the URL on which the page is located.
More than 1,000 Phishing Attacks on Universities Detected in a Year
According to Kaspersky Lab, more than 1,000 phishing attacks on universities have been detected in the past 12 months and 131 universities have been targeted. Those universities are spread across 16 countries, although 83/131 universities were in the United States.
Preventing phishing attacks on universities, staff, and students requires a multi layered approach. Technical controls must be implemented to reduce risk, such as an advanced spam filter to block the vast majority of phishing emails and stop them being delivered to end users. A web filtering solution is important for blocking access to phishing websites and web pages hosting malware. Multi-factor authentication is also essential to ensure that if account information is compromised or passwords are guessed, an additional form of authentication is required to access accounts.
As a last line of defense, staff and students should be made aware of the risk from phishing. Training should be made available to all students and cybersecurity awareness training for researchers, lecturers, and other staff should be mandatory.
TitanHQ, the leading provider of web filtering, spam filtering, and email archiving solutions for managed service providers (MSPs) recently formed a strategic partnership with Datto Networking, the leading provider of MSP-delivered IT solutions to SMBs.
The partnership has seen TitanHQ’s advanced web filtering technology incorporated into the Datto Networking Appliance to ensure all users benefit from reliable and secure internet access.
TitanHQ’s web filtering technology provides enhanced protection from web-based threats while allowing acceptable internet usage policies to be easily enforced for all users at the organization, department, user group, or user level.
On October 18, 2018, Datto and TitanHQ will be hosting a webinar to explain the enhanced functionality of the Datto Networking Appliance to MSPs, including a deep dive into the new web filtering technology.
Webinar: Datto Networking & Titan HQ Deliver Enhanced Web Content Filtering
Date: Thursday, October 18th
Time: 11AM ET | 8AM PT | 4PM GMT/BST
Speakers: John Tippett, VP, Datto Networking; Andy Katz, Network Solutions Engineer; Rocco Donnino, EVP of Strategic Alliances, TitanHQ
In 2015, Anthem Inc., experienced a colossal data breach. 78.8 million health plan records were stolen. This year, the health insurer settled a class action data breach for $115 million and OCR has now agreed a $16 million Anthem data breach settlement.
It Started with a Spear Phishing Email…
The Anthem data breach came as a huge shock back in February 2015, due to the sheer scale of the breach. Healthcare data breaches were common, but the Anthem data breach in a different league.
Prior to the announcement, the unenviable record was held by Science Applications International Corporation, a vendor used by healthcare organizations, that experienced a 4.9 million record breach in 2011. The Anthem data breach was on an entirely different scale.
The hacking group behind the Anthem data breach was clearly skilled. Mandiant, the cybersecurity firm that assisted with the investigation, suspected the attack was a nation-state sponsored cyberattack. The hackers managed to gain access to Anthem’s data warehouse and exfiltrated a huge volume of data undetected. The time of the initial attack to discovery was almost a year.
While the attack was sophisticated, a foothold in the network was not gained through an elaborate hack or zero-day exploit but through phishing emails.
At least one employee responded to a spear phishing email, sent to one of Anthem’s subsidiaries, which gave the attackers the entry point they needed to launch a further attack and gain access to Anthem’s health plan member database.
The Anthem Data Breach Settlement is the Largest Ever Penalty for a Healthcare Data Breach
The U.S. Department of Health and Human Services’ Office for Civil Rights (OCR) investigates healthcare data breaches that result in the exposure or theft of 500 or more records. An in-depth investigation of the Anthem breach was therefore a certainty given its scale. A penalty for non-compliance with Health Insurance Portability and Accountability Act (HIPAA) Rules was a very likely outcome as HIPAA requires healthcare organizations to safeguard health data. The scale of the breach also made it likely that it would result in the largest ever penalty for a healthcare data breach.
Before the Anthem data breach settlement, the largest penalty for a healthcare data breach was $5.55 million, which was agreed between OCR and Advocate Health Care Network in 2016. The Anthem data breach settlement was almost three times that amount, which reflected the seriousness of the breach, the number of people impacted, and the extent to which HIPAA Rules were alleged to have been violated.
OCR alleged that Anthem Inc., had violated five provisions of HIPAA Rules, and by doing so failed to prevent the breach and limit its severity. The Anthem data breach settlement was however agreed with no admission of liability.
The regulatory fine represents a small fraction of the total cost of the Anthem data breach. On top of the Anthem data breach settlement with OCR, Anthem faced multiple lawsuits in the wake of the data breach. The consolidated class action lawsuit was settled by Anthem in January 2018 for $115 million.
The class action settlement document indicated Anthem had already paid $2.5 to consultants in the wake of the breach, $31 million was spent mailing notification letters, $115 million went on improvements to security, and $112 million was paid to provide identity theft protection and credit monitoring services to affected plan members.
With the $115 million class action settlement and the $16 million OCR settlement, that brings the total cost of the Anthem data breach to $391.5 million.
At $391.5 million, that makes this the most expensive healthcare phishing attack by some distance and the cost clearly highlights just how important it is to adopt a defense-in-depth strategy to protect against phishing attacks.
Police in Iceland have said a highly sophisticated phishing attack is the largest ever cyberattack the country has ever experienced. The campaign saw thousands of messages sent that attempted to get Icelanders to install a remote access tool that would give the attackers full access to their computers.
The software used in this campaign is a legitimate remote access tool called Remcos. Remcos is used to allow remote access to a computer, often for the purpose of providing IT support, for surveillance, or as an anti-theft tool for laptop computers. However, while it was developed for legitimate use, because it gives the administrator full control over the computer once installed, it has significant potential to be used for malicious purposes. Unsurprisingly, Remcos has been used by cybercriminals in several malware campaigns in the past, often conducted via spear phishing campaigns. One notable attack involved the spoofing of the Turkish Revenue Administration, Turkey’s equivalent of the IRS, to get the RAT installed to provide access to victim’s computers.
The use of Remcos for malicious purposes violates the terms and conditions of use. If discovered, the developer can block the customer’s license to prevent use of the software. However, during the time that Remcos is present on a system, considerable harm can be caused – sabotage, theft of sensitive information, installation of malicious software, and file encryption with ransomware to name but a few.
As was the case in Turkey, the phishing campaign in Iceland attempted to fool end users into installing the program through deception. In this case, the emails claimed to have come from the Icelandic Police. The emails used fear to get recipients of the message to click a link in the email and download the remote access tool.
The emails informed the recipients that they were required to visit the police for questioning. Urgency was added by informing the recipient of the message that an arrest warrant would be issued if they failed to respond. Clicking the link in the email directed the user to what appeared to be the correct website of the Icelandic police. The website was a carbon copy of the legitimate website and required the visitor to enter their Social Security number along with an authentication code sent in the email to find out more information about the police case.
In Iceland, Social Security numbers are often required on websites to access official services, so the request would not appear unusual. On official websites, Social Security numbers are checked against a database and are rejected if they are not genuine. In this case, the attacker was also able to check the validity of the SSN, which means access to a database had been gained, most likely an old database that had been previously leaked or the attacker may have had legitimate access and misused the database.
After entering the information, a password protected archive was downloaded which allegedly contained documents with details of the case. The webpage provided the password to unlock the password protected archive, which contained a .scr file disguised as a Word document.
In this case, the RAT was augmented with a VBS script to ensure it ran on startup. The RAT had keylogging and password stealing capabilities and was used to steal banking credentials. After gaining access to banking credentials, the information was sent back to command and control servers in Germany and the Netherlands.
While the campaign looked entirely legitimate, a common trick was used to fool recipients of the email, which number in the thousands. The domain used in the attack closely resembled the official police website, logreglan.is but contained a lower case i instead of the second l – logregian.is. A casual glance at the sender of the email or the domain name in the address bar would unlikely reveal the domain was not genuine. Further, the link in the email replaced the lower case i with a capital I, which is almost impossible to distinguish from a lower-case L.
The Icelandic police responded quickly to the attack and the malicious domain was taken down the following day. It is unknown how may people fell for the scam.
A new sextortion scam has been detected that attempts to fool the recipient of the message into believing their email account has been compromised and that their computer is under full control of the attacker.
The scammers spoof the user’s email address so that it appears that the message has been sent from the user’s email account – The sender and the recipient names are identical.
A quick and easy check that can be performed to determine whether the sender name displayed is the actual account that has been used to send the email is to click forward. When this is done, the display name is shown, but so too is the actual email address that the message has been sent from. In this case, that check fails making it seem that the user’s email account has actually been compromised.
The messages used in this campaign attempt to extort money by suggesting the hacker has gained access to the user’s computer by means of a computer virus. It is claimed that the virus gives the attacker the ability to monitor the user’s internet activities in real time and use the computer’s webcam to record the user.
The attacker claims that the virus was downloaded to the computer as a result of the user visiting an adult website and that while viewing internet pornography the webcam was active and recording. “Your tastes are so weird,” states the scammer in the email.
The scammer claims that they will synch the webcam footage with the content that the user was viewing and send a copy of the video to all the user’s partner, friends, and relatives. It is claimed that all the user’s accounts have been compromised. The message also includes an example of one of the user’s passwords.
While it is extremely unlikely that the password supplied in the email is valid for any of the user’s account, the message itself will still be chilling for some individuals and will be enough to get them to make the requested payment of $800 to have the footage deleted.
However, this is a sextortion scam where the attackers have no leverage as there is no virus and no webcam footage. However, it is clear that at least some recipients were not willing to take a chance.
According to security researcher SecGuru, who received a version of the email in Dutch and found a similar English language version, the Bitcoin account used by the scammer had received payments of 0.37997578 Bitcoin – $3,500 – in the first two days of the campaign. Now 7 days after the first payment was made, the earnings have risen to 1.1203 Bitcoin – $6,418 – with 15 individuals having paid.
This scam will no doubt be familiar to viewers of Black Mirror, a recent episode of which covered a very similar sextortion scam.
This tactic is nothing new. Many similar scams have been conducted in the past and many more will be in the future. What makes this campaign more chilling is the apparent hijacking of the email account and the highly effective spoofing.
A similar sextortion scam was conducted in the summer which also had an interesting twist. It used an old password for the account that had been obtained from a data dump. In that case, the password was real, at least at some point in the past, which made the scam seem genuine.
Office 365 phishing attacks are commonplace, highly convincing, and Office 365 spam filtering controls are easily being bypassed by cybercriminals to ensure messages reach inboxes. Further, phishing forms are being hosted on webpages that are secured with valid Microsoft SLL certificates to convince users the websites are genuine.
Office 365 Phishing Attacks Can Be Difficult to Identify
In the event of a phishing email making it past perimeter defenses and arriving in an inbox, there are several tell-tale signs that the email is not genuine.
There are often spelling mistakes, incorrect grammar, and the messages are sent from questionable senders or domains. To improve the response rate, cybercriminals are now spending much more time carefully crafting their phishing emails and they are often virtually indistinguishable from genuine communications from the brand they are spoofing. In terms of formatting, they are carbon copies of genuine emails complete with the branding, contact information, sender details, and logos of the company being spoofed. The subject is perfectly believable and the content well written. The actions the user is requested to take are perfectly plausible.
Hyperlinks are contained in emails that direct users to a website where they are required to enter their login credentials. At this stage of the phishing attack there are usually further signs that all is not as it seems. A warning may flash up that the website may not be genuine, the website may start with HTTP rather than the secure HTTPS, or the SSL certificate may not be owned by the company that the website is spoofing.
Even these tell-tale signs are not always there, as has been shown is several recent Office 365 phishing attacks, which have the phishing forms hosted on webpages that have valid Microsoft SSL certificates or SSL certificates that have been issued to other cloud service providers such as CloudFlare, DocuSign, or Google.
Microsoft Azure Blog Storage Phishing Scam
One recent phishing scam uses Azure blob storage to obtain a valid SSL certificate for the phishing form. Blob storage can be used for storing a variety of unstructured data. While it is possible to use HTTP and HTTPS, the phishing campaign uses the latter, which will show a signed SSL certificate from Microsoft.
In this campaign, end users are sent an email with a button that must be clicked to view the content of a cloud-hosted document. In this case, the document appears to be from a Denver law firm. Clicking the button directs the user to an HTML page hosted on Azure blog storage that requires Office 365 credentials to be entered to view the document. Since the document is hosted on Azure blob storage, a Microsoft service, it has a valid SSL certificate that was issued to Microsoft adding legitimacy to the scam.
Entering login credentials into the form will send them to the attackers. The user will then be directed to another webpage, most likely unaware that they have been phished.
CloudFlare IPFS Gateway Abused
A similar campaign has been detected that abuses the CloudFlare IPFS gateway. Users can access content on the IPFS distributed file system through a web browser. When connecting to this gateway through a web browser, the HTML page will be secured with a CloudFlare SSL certificate. In this case, the login requires information to be entered including username, password, and recovery email address and phone number – which will be forwarded to the attacker, while the user will be directed to a PDF file unaware that their credentials have been stolen.
Office 365 Phishing Protections are Insufficient
Office 365 users are being targeted by cybercriminals as they know Office 365 phishing controls can be easily bypassed. Even with Microsoft’s Advanced Threat Protection for Office 365, phishing emails are still delivered. A 2017 study by SE Labs showed even with this additional anti-phishing control, Office 365 anti-phishing measures were only rated in the low-middle of the market for protection. With only the basic Exchange Online Protection, the protection was worse still.
Whether you run an SMB or a large enterprise, you are likely to receive high volumes of spam and phishing emails and many messages will be delivered to end users’ inboxes. Since the emails can be virtually impossible for end users to identify as malicious, it is probable that all but the most experienced, well trained, security conscious workers will be fooled. What is therefore needed is an advanced third-party spam filtering solution that will work alongside Office 365 spam filtering controls to provide far greater protection.
How to Make Office 365 More Secure
While Office 365 will block spam emails and phishing emails (Osterman Research showed it blocks 100% of known malware), it has been shown to lack performance against advanced phishing threats such as spear phishing.
Office 365 does not have the same level of predictive technology as dedicated on-premises and cloud-based email security gateways which are much better at detecting zero-day attacks, new malware, and advanced spear phishing campaigns.
To greatly improve protection what is needed is a dedicated third-party spam filtering solution for Office 365 such as SpamTitan. SpamTitan focuses on defense in depth, and provides superior protection against advanced phishing attacks, new malware, and sophisticated email attacks to ensure malicious messages are blocked or quarantined rather than being delivered to end users’ inboxes. Some of the additional protections provided by SpamTitan against Office 365 phishing attacks are detailed in the image below:

Cybercriminals have turned to cryptocurrency mining malware as an easy, low-risk way of making money although ransomware is still the main malware threat according to Europol.
While it was common for large-scale spam email campaigns to be sent to random recipients to spread ransomware, tactics used to infect devices with the file-encrypting malware are changing.
There has been a decline in the use of ‘spray and pray’ spam campaigns involving millions of messages toward targeted attacks on businesses. Organized cybercriminal gangs are researching victims and are conducting highly targeted attacks that first involve compromising a network before manually deploying ransomware.
The cybercriminal group behind SamSam ransomware has been particularly prolific. Companies that have failed to address software vulnerabilities are attacked and access is gained to their networks. The SamSam group also conducts brute force attacks on RDP to gain access to business networks. Once access is gained, ransomware is manually installed on as many computers as possible, before the encryption routine is started across all infected devices. With a large number of devices encrypted, the ransom demand can be much higher – Typically around $50,000 per company. The group has collected at least $6 million in ransom payments to date.
Europol warns that ransomware attacks will continue to be a major threat over the following years, although a new threat is emerging – cryptojacking malware. This form of malware is used to hijack computer processors to mine cryptocurrency. Europol warns that if the rise in the use of cryptojacking malware continues it may overtake ransomware and become the biggest malware threat.
Not only does cryptojacking offer considerable rewards, in many cases use of the malware is not classed as illegal, such as when it is installed on websites. This not only means that cybercriminals can generate considerable profits, but the risk involved in these types of attacks is far lower than using ransomware.
Cybercriminals are still extensively using social engineering techniques to fool consumers and employees into disclosing sensitive personal information and login credentials. Social engineering is also extensively used to trick employees into making fraudulent bank transfers. Phishing is the most common form of social engineering, although vishing – voice phishing – and smishing – SMS phishing are also used. Europol notes that social engineering is still the engine of many cybercrimes.
While exploit kits have been extensively used to silently download malware, Europol notes that the use of exploit kits continues to decline. The main attack vectors are spam email and RDP brute-forcing.
As-a-service cyberattacks continue to be a major problem. DDoS-as-a-service and ransomware-as-a-service allow low-level and relatively unskilled individuals to conduct cyberattacks. Europol recommends law enforcement should concentrate on locating and shutting down these criminal operations to make it much harder for low-level criminals to conduct cyberattacks that would otherwise be beyond their skill level.
With spam email still a major attack vector, it is essential for businesses to implement cybersecurity solutions to prevent malicious emails from being delivered to inboxes and ensure cybersecurity best practices are adopted to make them less susceptible to attack. With phishing the main form of social engineering, anti-phishing training for employees is vital.
RDP attacks are now commonplace, so steps must be taken by businesses to block this attack vector, such as disabling RDP if it is not required, using extremely strong passwords for RDP, limiting users who can login, configuring account lockouts after a set number of failed login attempts, and using RDP gateways.
With the largest economy, the United States is naturally a major target for cybercriminals. Various studies have been conducted on the cost of cybercrime in the United States, but little data is available on cybercrime losses in Germany – Europe’s largest economy.
The International Monetary Fund produces a list of countries with the largest economies. In 2017, Germany was ranked fourth behind the United States, China, and Japan. Its GDP of $3,68 trillion represents 4.61% of global GDP.
A recent study conducted by Germany’s federal association for Information Technology – BitKom – has placed a figure on the toll that cybercrime is taking on the German economy.
The study was conducted on security chiefs and managers at Germany’s top 503 companies in the manufacturing sector. Based on the findings of that survey, BitKom estimated cybercrime losses in Germany to be €43 billion ($50.2 billion). That represents 1.36% of the country’s GDP.
Extrapolate those cybercrime losses in Germany and it places the global cost of cybercrime at $1 trillion, substantially higher than the $600 billion figure estimate from cybersecurity firm McAfee and the Center for Strategic and International Studies (CSIS) in February 2018. That study placed the global percentage of GDP lost to cybercrime at between 0.59% and 0.80%, with GDP losses to cybercrime across Europe estimated to be between 0.79 to 0.89% of GDP.
Small to Medium Sized Businesses Most at Risk
While cyberattacks on large enterprises have potential to be highly profitable for cybercriminals, those firms tend to have the resources available to invest heavily in cybersecurity. Attacks on large enterprises are therefore much more difficult and time consuming. It is far easier to target smaller companies with less robust cybersecurity defenses.
Small to medium sized businesses (SMBs) often lack the resources to invest heavily in cybersecurity, and consequently are far easier to attack. The BitKom study confirmed that these companies, which form the backbone of the economy in Germany, are particularly vulnerable to cyberattacks and have been extensively targeted by cybercriminals.
It is not only organized cybercriminal groups that are conducting these attacks. Security officials in Germany have long been concerned about attacks by well-resourced foreign spy agencies. Those agencies are using cyberattacks to gain access to the advanced manufacturing techniques developed by German firms that give them a competitive advantage. Germany is one of the world’s leading manufacturing nations, so it stands to reason that the German firms are an attractive target.
Cybercriminals are extorting money from German firms and selling stolen data on the black market and nation-state sponsored hackers are stealing proprietary data and technology to advance manufacturing in their own countries. According to the survey, one third of companies have had mobile phones stolen and sensitive digital data has been lost by a quarter of German firms. 11% of German firms report that their communications systems have been tapped.
Attacks are also being conducted to sabotage German firms. According to the study, almost one in five German firms (19%) have had their IT and production systems sabotaged through cyberattacks.
Businesses Must Improve Their Defenses Against Cyberattacks
“With its worldwide market leaders, German industry is particularly interesting for criminals,” said Achim Berg, head of BitKom. Companies, SMBs in particular, therefore need to take cybersecurity much more seriously and invest commensurately in cybersecurity solutions to prevent cybercriminals from gaining access to their systems and data.
According to Thomas Haldenweg, deputy president of the BfV domestic intelligence agency, “Illegal knowledge and technology transfer … is a mass phenomenon.”
Preventing cyberattacks is not straightforward. There is no single solution that can protect against all attacks. Only defense-in-depth will ensure that cybercriminals and nation-state sponsored hacking groups are prevented from gaining access to sensitive information.
Companies need to conduct regular, comprehensive organization-wide risk analyses to identify all threats to the confidentiality, integrity, and availability of their data and systems. All identified risks must then be addressed through a robust risk management process and layered defenses implemented to thwart attackers.
One of the main vectors for attack is email. Figures from Cofense suggest that 91% of all cyberattacks start with a malicious email. It stands to reason that improving email security should be a key priority for German firms. This is an area where TitanHQ can help.

Managed service providers (MSPs) are discovering the huge potential for profit from offering security-as-a-service to their clients. Managed security services are now the biggest growth area for the majority of leading MSPs, with security-as-a-service well ahead of cloud migration, cloud management, and managed Office 365 services according to a recent survey conducted by Channel Futures.
Channel Futures conducted the survey as part of its annual MSP 501 ranking initiative, which ranks MSPs based on their ability to act on current trends and ensure they remain competitive in the fast-evolving IT channel market. The survey evaluated MSP revenue growth, hiring trends, workforce dynamics, service deliverables, business models, and business strategies.
The survey revealed that by far the biggest growth area is managed security services. Security-as-a-service was rated the biggest growth area by 73% of MSPs. 55% of MSPs said professional services were a major growth area, 52% said Office 365, and 51% said consulting services.
It is no surprise that security-as-a-service is proving so popular as the volume of attacks on enterprises and SMBs has soared. Cybercriminals are attacking enterprises and SMBs trying to gain access to sensitive data to sell on the black market. Attacks are conducted to sabotage competitors, nation-state-sponsored hackers are attempting to disrupt critical infrastructure, and data is being encrypted to extort money. There is also a thriving market for proprietary data and corporate secrets.
The cost of mitigating attacks when they succeed is considerable. For enterprises, the attacks can make a significant dent in profits, but cyberattacks on SMBs can be catastrophic. A study conducted by the National Cyber Security Alliance suggests as many as 60% of SMBs go out of business in the 6 months following a hacking incident.
Enterprises and SMBs alike have had to respond to the increased threat by investing heavily in security, but simply throwing money at security will not necessarily mean all security breaches are prevented. Companies need to employee skilled IT security professionals to implement, monitor and maintain those cybersecurity solutions, conduct vulnerability scans, and identify and address security gaps. Unfortunately, there is a major shortage of skilled staff and attracting the right talent can be next to impossible. Faced with major challenges, many firms have turned to MSPs to and have signed up for security-as-service offerings.
Forward-thinking MSPs have seized the opportunity and are now providing a comprehensive range of managed security services to meet the needs of their clients. They are offering a wide range of tools and services from phishing protection to breach mitigation services; however, for many MSPs, developing such a package is not straightforward.
Security-as-a-service is in high demand, but MSPs must be able to package the right services to meet customers’ needs and have a platform that can handle the business end. They too must attract the staff who can implement, monitor, and manage those services for their clients.
When devising a security-as-a-service offering, one option is to use a common security architecture for all clients and provide them with a range of solutions from the same provider. Many companies have implemented a slew of different security tools from multiple providers, only to discover they are still experiencing breaches. It is a relatively easy sell to get them to move over to a system where all the component parts are seamlessly integrated and to benefit from an MSP’s expertise in managing those solutions. There is a risk of course that clients will just choose to go direct rather than obtain those services from an MSP. This single platform strategy has been adopted by Liberty Technology – ranked 242 in the MSP 501 list – and is working well, especially for clients that have fewer than 1,000 employees.
At the other end of the spectrum is Valiant Technologies, ranked 206 in the MSP 501 list. Valiant has chosen a wide range of products from multiple cybersecurity solution providers and has built a unique package of products for its security service.
The products were chosen for the level of protection they offered and how well they work together. This approach has been a success for the firm. “Providing a bundle of offerings from different vendors that work well together is the most effective way for an MSP to retain its role as a trusted adviser,” said the firm’s CEO Tom Clancy. The security service has been added to other business services provided by the MSP and has proved to be an easy sell to clients.
ComTec Solutions, which ranked in position 248 in the MSP 501 list, is still deciding on the best way forward. The provision of security-as-a-service is a no brainer, but the company is currently assessing whether it is worthwhile building a security operations center (SOC) and becoming a managed security service provider (MSSP) or outsourcing the SOC service.
There are several different approaches to take when developing a managed security service offering. What is vital is that such a service is provided. The MSP 501 survey has shown that the most successful MSPs have responded to demand and are now helping their clients secure their networks through their security-as-a-service offerings. Those MSPs are clearly reaping the rewards.
If you are an MSP that is considering developing a security-as-a-service offering, be sure to speak to TitanHQ about its world-class cloud-based security solutions for MSPs – WebTitan and SpamTitan – and find out how they can be integrated into your security stack.
A new Python-based form of ransomware has been detected that masquerades as Locky, one of the most widely used ransomware variants in 2016. The new ransomware variant has been named PyLocky ransomware by security researchers at Trend Micro who have observed it being used in attacks in Europe, particularly France, throughout July and August.
The spam email campaigns were initially sent in relatively small batches, although over time the volume of emails distributing PyLocky ransomware has increased significantly.
Various social engineering tactics are being used by the attackers to get the ransomware installed, including fake invoices. The emails intercepted by Trend Micro have included an embedded hyperlink which directs users to a malicious webpage where a zip file is downloaded. The zip file contains PyLocky ransomware which has been compiled using the PyInstaller tool, which allows Python applications to be converted to standalone executable files.
If installed, PyLocky ransomware will encrypt approximately 150 different file types including Office documents, image files, sound files, video files, databases, game files, archives, and program files. Files stored on all logical drives will be encrypted and the original copies will be overwritten. A ransom note is then dropped on the desktop which has been copied from the note used by the threat actors behind Locky, although the two cryptoransomware threats are unrelated. Ransom notes are written in French, English, Korean, and Italian so it is probable that the attacks will become more widespread over the coming weeks.
While Python is not typically used to create ransomware, PyLocky is not the only Python-based ransomware variant to have been created. Pyl33t was used in several attacks in 2017, and CryPy emerged in 2016. What makes the latest ransomware variant stand out is its anti-machine learning capabilities, which help to prevent analysis using standard static analysis methods.
The ransomware abuses Windows Management Instrumentation (WMI) to determine the properties of the system on which it is installed. If the total visible memory of a system is 4GB or greater, the ransomware will execute immediately. If it is lower than 4GB, the ransomware will sleep for 11.5 days – an attempt to determine if it is in a sandbox environment.
Preventing attacks requires a variety of cybersecurity measures. An advanced spam filtering solution such as SpamTitan will help to prevent the spam emails being delivered to end users’ inboxes. A web filter, such as WebTitan, can be employed to control the websites that can be accessed by end users and block malicious file downloads. Security awareness training will help to ensure that end users recognize the threat for what it is. Advanced malware detection tools are required to identify the threat due to its anti-machine learning capabilities.
There is no free decryptor for PyLocky. Recovery without paying the ransom will depend on a viable backup copy existing, which has not also been encrypted in the attack.
A spam email campaign is being conducted targeting corporate email accounts to distribute Loki Bot malware. Loki Bot malware is an information stealer capable of obtaining passwords stored in browsers, obtaining email account passwords, FTP client logins, cryptocurrency wallet passwords, and passwords used for messaging apps.
In addition to stealing saved passwords, Loki Bot malware has keylogging capabilities and is potentially capable of downloading and running executable files. All information captured by the malware is transferred to the attacker’s C2 server.
Kaspersky Lab researchers identified an increase in email spam activity targeting corporate email accounts, with the campaign discovered to be used to spread Loki Bot malware. The malware was delivered hidden in a malicious email attachment.
The intercepted emails included an ICO file attachment. ICO files are copies of optical discs, which are usually mounted in a virtual CD/DVD drive to open. While specialist software can be used to open these files, most modern operating systems have the ability to access the contents of the files without the need for any additional software.
In this case, the ICO file contains Loki Bot malware and double clicking on the file will result in installation of the malware on operating systems that support the files (Vista and later).
It is relatively rare for ICO files to be used to deliver malware, although not unheard of. The unfamiliarity with ICO files for malware delivery may see end users attempt to open the files.
The campaign included a wide range of lures including fake purchase orders, speculative enquiries from companies containing product lists, fake invoices, bank transfer details, payment requests, credit notifications, and payment confirmations. Well-known companies such as Merrill Lynch, Bank of America, and DHL were spoofed in some of the emails.
A separate and unrelated spam email campaign has been identified that is using IQY files to deliver a new form of malware known as Marap. Marap malware is a downloader capable of downloading a variety of different payloads and additional modules.
Upon installation, the malware fingerprints the system and gathers information such as username, domain name, IP address, hostname, language, country, Windows version, details of Microsoft .ost files, and any anti-virus solutions detected on the infected computer. What happens next depends on the system on which it is installed. If the system is of particular interest, it is earmarked for a more extensive compromise.
Four separate campaigns involving millions of messages were detected by researchers at Proofpoint. One campaign included an IQY file as an attachment, one included an IQY file within a zip file and a third used an embedded IQY file in a PDF file. The fourth used a Microsoft Word document containing a malicious macro. The campaigns appear to be targeting financial institutions.
IQY files are used by Excel to download web content directly into spreadsheets. They have been used in several spam email campaigns in recent weeks to install a variety of different malware variants. The file type is proving popular with cybercriminals because many anti-spam solutions fail to recognize the files as malicious.
Since the majority of end users would not have any need to open ICO or IQY files, these file types should be added to the list of blocked file types in email spam filters to prevent them from being delivered to end users’ inboxes.
While the majority of phishing attempts are conducted via email, there has been a significant rise in the use of other communications platforms such messaging services, with WhatsApp phishing scams now increasing in popularity amongst phishers.
WhatsApp phishing attacks are common for two main reasons. First is the sheer number of people that are on the platform. In January 2018, the number of monthly users of WhatsApp worldwide reached 1.5 billion, up from 1 billion users six months previously. Secondly, is the lack of anti-phishing measures to prevent malicious messages from being delivered.
Many businesses have implemented spam filtering solutions such as SpamTitan, while personal users are benefiting by significant improvements to spam filtering on webmail services such as Gmail. Spam filtering solutions are highly effective at identifying phishing emails and other malicious messages and send them to the spam folder rather than delivering them to inboxes.
Messaging services often lack spam filtering controls. Therefore, malicious messages have a much greater chance of being delivered. Various tactics are used to entice recipients to click the links in the messages, usually an offer of a free gift, an exceptionally good special offer on a product – the new iPhone for instance – or a money off voucher or gift card is offered.
The messages contain a link that directs the recipient to the phishing website. The link usually contains a preview of the website, so even if a shortlink is used for the URL, the recipient can see some information about the site. A logo may be displayed along with the page title. That makes it much more likely that the link will be clicked.
Further, the message often comes from a known individual – A person in the user’s WhatsApp contact list. When a known individual vouches for the site, the probability of the link being clicked is much greater.
To add further legitimacy to the WhatsApp phishing scams, the websites often contact fake comments from social media sites confirming that a gift card has been won or a reward has been received. Some of those comments are positive, and some are neutral, as you would expect from a real prize draw where not everyone is a winner.
The websites used in WhatsApp phishing scams often use HTTPS, which show a green tick next to the URL to show that the site is ‘secure.’ Even though the green tick is no guarantee of the legitimacy of a site, many people believe the green tick means the site is genuine.
Gift cards are often given out for taking part in legitimate surveys, so the offer of either a gift card or entry into a free draw is not out of the ordinary. In return, the visitor to the site is required to answer some standard questions and provide information that would allow them to be contacted – their name, address, phone number, and email address for instance.
The information gathered through these sites is then used for further phishing attempts via email, telephone, or snail mail which aim to obtain even more personal information. After completing the questions, the website may claim that the user has one, which requires entry of bank account information or credit card details… in order for prize money to be paid or for confirmation of age.
These WhatsApp phishing scams often have another component which helps to spread the messages much more efficiently to other potential victims. Before any individual can claim their free prize or even submit their details for a prize draw, they must first agree to share the offer with some of their WhatsApp contacts.
If you receive an unsolicited link from a contact that offers a free gift or money-off voucher, there is a high chance it may not be genuine and is a WhatsApp phishing scam. If an offer seems too good to be true, it most likely is.
Hotels, restaurants, and telecommunications companies are being targeted with a new spam email campaign that delivers a new form of malware called AdvisorsBot. AdvisorsBot is a malware downloader which, like many malware variants, is being distributed vis spam emails containing Microsoft Word attachments with malicious macros.
Opening an infected email attachment and enabling macros on the document will see Advisorsbot installed. Advisorsbot’s primary role is to perform fingerprinting on an infected device. Information will be gathered on the infected device is then communicated to the threat actors’ command and control servers and further instructions are provided to the malware based on the information gathered on the system. The malware records system information, details of programs installed on the device, Office account details, and other information. It is also able to take screenshots on an infected device.
AdvisorsBot malware is so named because the early samples of the malware that were first identified in May 2018 contacted command and control servers that contained the word advisors.
The spam email campaign is primarily being conducted on targets in the United States, although infections have been detected globally. Several thousands of devices have been infected with the malware since May, according to the security researchers at Proofpoint who discovered the new malware threat. The threat actors believed to be behind the attacks are a APT group known as TA555.
Various email lures are being used in this malware campaign to get the recipients to open the infected attachment and enable macros. The emails sent to hotels appear to be from individuals who have been charged twice for their stay. The campaign on restaurants uses emails which claim that the sender has suffered food poisoning after eating in a particular establishment, while the attacks on telecommunications companies use email attachments that appear to be resumes from job applicants.
AdvisorsBot is written in C, but a second form of the malware has also been detected that is written in .NET and PowerShell. The second variant has been given the name PoshAdvisor. PoshAdvisor is executed via a malicious macro which runs a PowerShell command that downloads a PowerShell script which executes shellcode that runs the malware in the memory without writing it to the disk.
These malware threats are still under development and are typical of many recent malware threats which have a wide range of capabilities and the versatility to be used for many different types of attack such as information stealing, ransomware delivery, and cryptocurrency mining. The malicious actions performed are determined based on the system on which the malware has been installed. If that system is ideally suited for mining cryptocurrency, the relevant code will be installed. If the business is of particular interest, it will be earmarked for a more extensive compromise.
The best form of defense against this campaign is the use of an advanced spam filtering solution to prevent the emails from being delivered and security awareness training for employees to condition them how to respond when such a threat arrives in their inbox.
Two factor authentication flaws have been identified that allow accounts to be accessed even when protected by a password and second authentication factor.
Two-factor authentication is an important safeguard to secure accounts. In the event of login credentials being guessed or otherwise obtained by a third party, an additional method of authentication is required to gain access to the account. Without that second factor, access to the account is blocked. But not always. Multiple two-factor authentication flaws have been identified.
Two Factor Authentication Flaws Exploited in Reddit, LinkedIn and Yahoo Cyberattacks
Two-factor authentication is not infallible. Recently, Reddit disclosed that it had suffered a data breach even though two factor authentication had been implemented. Rather than use a token, Reddit used SMS messages to a mobile phone owned by the account holder as the second authentication factor. As Reddit discovered, SMS messages can be intercepted. The attacker was able to intercept a 2FA SMS message and gain access to an employee’s account, through which it was possible to access to an old database of user credentials.
Two-factor authentication was also in place at Yahoo in 2013, yet the company still experienced a massive data breach that resulted in all three billion of its users having their information obtained by hackers. Go back a year and there was the massive 167 million record data breach at LinkedIn, which had also implemented two-factor authentication.
A phone call or text message to a phone owned by the account holder does not necessarily prevent access to the account from being gained by a third party. In August last year, a Bitcoin investor had $150,000 of cryptocurrency stolen from his wallet after it was accessed by a third party. In that case, the investor’s second factor phone number had been re-routed to a device owned by the attacker after the phone company was duped.
Any second factor that uses the phone system of SMS messages provides an additional layer of protection, but it is not enough to protect against a determined skilled hacker.
Two Factor Authentication Flaws Discovered in Microsoft’s Active Directory Federation Services
A major two-factor authentication vulnerability was recently discovered by a security researcher at Okta. Okta, like many companies, uses Microsoft’s Active Directory Federation Services (ADFS) to provide multi-factor authentication.
Okta security researcher Andrew Lee discovered the system have a serious vulnerability that was not only straightforward to exploit, doing so would render an organization’s multi-factor authentication controls virtually useless.
Lee discovered that someone with a username, password, and a valid 2-factor token for one account could use the same token to gain access to any other account in the organization in AD with only a username and password. Any employee who is given an account and specified their own second factor could use it to access other accounts. Essentially the token was like a hotel room key card that opens all rooms in the hotel.
Obtaining another employee’s login credentials would only require a phishing campaign to be conducted. If an individual responded and disclosed their credentials, their account could be accessed without the need for a second factor.
The vulnerability in question, which was patched by Microsoft on August 14 in its August Patch Tuesday updates, was present in how ADFA communicates. When a user tries to login, an encrypted context log is sent by the server which contains the second factor token but not the username. This flaw could be exploited to fool the system into thinking the correct token had been supplied, as no check was made to determine whether the correct token had been supplied for a specific user’s account. As long as one valid username, password and 2FA token combo was owned, the 2FA system could be bypassed.
Two factor Authentication is Not a Silver Bullet
These two factor authentication flaws show that while 2-factor authentication is an important control to implement, businesses should not rely on the system to prevent unauthorized accessing of accounts. The two-factor authentication flaws discussed here are unlikely to be the last to be uncovered.
2-factor authentication should be just one element of an organization’s defenses against phishing and hacking, along with spam filters web filters, firewalls, intrusion detection systems, antivirus solutions, network segmentation, and employee security awareness training. 2FA should not be viewed as a silver bullet to prevent unauthorized account access.
A new sextortion phishing threat has been detected that is proving to have the desired effect. Many recipients of the emails have paid up to avoid being exposed.
On the face of it, this sextortion phishing scam is as simple as it gets. A threat actor claims to have taken control of the target’s computer and recorded them via their webcam while they were visiting an adult website. A threat is made to publicly release the video of them viewing pornography unless a payment is made.
For some recipients of such an email, such a threat would be enough to get them opening their Bitcoin wallet and making the payment without a second’s hesitation. Most people would likely see the email for what it really is. A scam and an empty threat.
However, a second variant of the email is being used that is a lot more personalized and includes a snippet of information to add credibility to the scam. The message includes the user’s password as ‘confirmation’ that it is not an empty threat. The attacker also claims, through compromising the target’s computer, to have obtained all the victim’s contacts including contacts in their social media accounts.
While the threat actor claims to have control of the user’s computer, that is not the case. The password has been obtained from a previous data breach and a list has likely been purchased on the darknet.
For many of the email recipients, the password will be old and will have been changed long ago. That may be enough in some cases to see payment made. However, for those who are still using that password, the threat may seem very real.
This is in reality a very simple scam that in many cases only works because despite the risk of failing to change passwords frequently, recycling old passwords, and reusing passwords on multiple sites, the practice is still commonplace.
It is not known how many emails have been sent by the scammers – most likely millions – but it only takes a handful of people to respond and make payment for the scheme to be profitable.
So far, at least 151 people have responded to the sextortion phishing scam and made a payment to one of 313 Bitcoin addresses known to be used by the scammers. So far, at least 30.08 BTC had been raised – Approximately $250,000 – from the scam as of July 26 and it has only been running for a few weeks. The researcher tracking the payments (SecGuru) pointed out that the attackers have made three times as much as the individuals behind the WannaCry ransomware attacks last year.
Even without the password, the sextortion phishing scam has proved effective. Payments have been made in both versions of the scam. The standard scam asks for a payment of a few hundred dollars, although the inclusion of a password sees the payment rise considerably. Some individuals have been told it will cost them $8,000 to prevent the release of the video. Some individuals have paid thousands to the scammers.
Given the widespread coverage of the scam, and its success rate, it is probable that many more similar schemes will be conducted. Variations along the same theme could direct recipients to a phishing website where they are enticed into disclosing their current password, to an exploit kit that downloads malware, or to another scam site.
Protecting against a scam such as this is easiest by using strong passwords, regularly changing them, and never reusing passwords on multiple sites. It is also worthwhile periodically checking to find out if their credentials have been exposed in a data breach on HaveIBeenPwned.com and immediately changing passwords if they have.
Anyone receiving a sextortion phishing email such as this should be aware that this is a scam. If the password included is currently being used, it is essential to change it immediately across all sites. And of course, set a strong, unique password for each account.
The past year has seen a steady increase in the number of reported email account compromises, with the healthcare industry one of the main targets for hackers.
Some of those breaches have seen the protected health information of thousands of patients compromised, with the largest phishing attack in 2018 – The phishing attack on Boys Town National Research Hospital – seeing more than 105,000 patients’ healthcare information exposed. Due to reporting requirements under HIPAA, healthcare phishing attacks are highly visible, although email account compromises are occurring across all industry sectors and the problem is getting worse.
284% Increase in Email Account Compromises in a Year
The increase in successful phishing attacks has been tracked by Beazley, a provider of specialist insurance services. The company’s research shows the number of reported phishing attacks increased every quarter since Q1, 2017 when there were 45 reported breaches that involved email accounts being compromised. In Q2, 2018, there were 184 email account compromises reported. Between Q1, 2017 and Q1, 2018, the number of reported data breaches involving compromised email accounts increased by 284%.
Why are email account compromises increasing? What do hackers gain from accessing email accounts rather than say, gaining access to networks which store vast amounts of data?
It can take a significant amount of time and effort to identify a vulnerability such a missed patch, an exposed S3 bucket, or an unsecured medical device, and exploit it.
By comparison, gaining access to an email account is relatively easy. Once access is gained, accessing further email accounts becomes easier still. If a hacker can gain access to an email account with the right level of administrative privileges, it may be possible for the entire mail system of an organization to be accessed.
If a hacker can gain access to a single email account, the messages in the account can be studied to gain valuable information about a company, its employees, and vendors. The hackers can identify further targets within an organization for spear phishing campaigns – termed Business Email Compromise (BEC) attacks – and attacks on contractors and suppliers.
Once One Account is Breached, Others Will Follow
If an executive’s email account is compromised, it can be used to send requests for wire transfers to the accounts department, HR can be emailed requesting W2-Forms that contain all the information necessary for filing fake tax returns and for identity theft. Requests can be sent via email to redirect employees’ paychecks and phishing emails can be sent to other employees directing them to websites where they have to divulge their email credentials.
Figures from the FBI show just how lucrative these Business Email Compromise (BEC) phishing attacks can be. Since October 2013, more than $12.5 billion has been lost to BEC attacks, up from $5.3 billion in December 2016.
Once access to the email system is gained, it is much easier to craft highly convincing spear phishing emails. Past email conversations can be studied, and an individual’s style of writing emails can be copied to avoid raising any red flags.
Email Account Compromises Are Costly to Resolve
Beazley also notes that email account compromises are some of the costliest breaches to resolve, requiring many hours of painstaking work to manually checking each email in a compromised account for PII and PHI. One example provided involved a programmatic search of compromised email accounts to identify PHI, yet that search uncovered 350,000 documents that required a manual check. The cost of checking those documents alone was $800,000.
Beazley also notes that when investigating breaches, the breached entity often discovers that only half of the compromised email accounts have been identified. The data breaches are usually much more extensive than was initially thought.
Unfortunately, once access to a single email account is gained, it is much harder to prevent further email compromises as technological controls are not so effective at identifying emails sent from within a company. However, it is relatively easy to block the initial phishing attempt.
How to Prevent Email Account Compromises
Many companies fail to implement basic controls to block phishing attacks. Even when a phishing-related breach is experienced, companies often remain susceptible to further breaches. The Ponemon Institute/IBM Security Cost of a Data Breach study showed there is a 27.9% probability of a company experiencing a further breach in the 24 months following a data breach.
To prevent phishing attacks, companies need to:
Deploy an advanced spam filtering solution that blocks the vast majority of malicious messages
Provide ongoing security awareness training to all staff and teach employees how to identify phishing emails
Conduct regular phishing simulation exercises to reinforce training and condition employees to be more security aware
Implement two-factor authentication to prevent attempts to access email accounts remotely
Implement a web filter as an additional control to block the accessing of phishing websites
Use strong, unique passwords or passphrases to make brute force and dictionary attacks harder
Limit or prevent third party applications from connecting to Office 365 accounts, which makes it harder for PowerShell to be used to access email accounts for reconnaissance.
In recent weeks, several large healthcare data breaches have been reported that have seen cybercriminals gain access to employees’ email accounts and sensitive data, although the recently disclosed UnityPoint Health phishing attack stands out due to the huge number of individuals that have been impacted and the extent of sensitive data exposed.
UnityPoint Health is one of the largest healthcare systems serving Iowa residents. The Des Moines-based healthcare provider recently discovered that its employees have been targeted in a phishing campaign that has seen several email accounts compromised. Those email accounts contained the sensitive information of approximately 1.4 million patients.
That not only makes this the largest phishing incident to have been suffered by a U.S. healthcare provider in 2018, it is also the largest healthcare data breach of 2018 and one of the most serious phishing attacks and data breaches ever reported.
The UnityPoint Health phishing attack has seen highly sensitive data compromised, including names, addresses, health insurance information, medical record numbers, diagnoses, treatment information, lab test results, medications, providers, dates of service, Social Security numbers, driver’s license numbers and, for a limited number of patients, their payment card information.
The phishing emails were sent to employees between March 14 and April 3, 2018, although the breach was not detected until May 31. As is common in phishing attacks on businesses, access to email accounts was gained through the impersonation of a senior executive.
A series of spoofed emails were sent to employees that appeared to have come from a trusted executive’s email account. Employees who opened the email were instructed to click a link that required them to enter their email login information. That information was captured by the attackers who were then able to gain access to the employees’ email accounts.
The UnityPoint Health phishing attack potentially gave the hackers access to all the information stored in the compromised email accounts – Information that could be used for identity theft and fraud. It is unclear whether mailboxes were downloaded, although UnityPoint Health said its forensic investigation suggests that the primary goal was to divert payroll payments and to use account access to fool accounts department staff into making fraudulent wire transfers. It is unclear if any of those attempts succeeded.
This is also not the only UnityPoint Health phishing attack to be reported this year. In March, UnityPoint Health announced that 16,400 patients had been affected by a separate phishing attack that saw multiple email accounts compromised.
The latest incident has prompted the healthcare provider to implement new technology to detect phishing and BEC attacks, multi-factor authentication has been implemented, and additional security awareness training has been provided to employees. Credit monitoring and identify theft monitoring services have been offered to patients whose driver’s license or Social Security number has been exposed, and all patients have been notified by mail.
As the Ponemon Institute’s 2018 Cost of a Data Breach Study showed, the cost of these million-record+ data breaches is considerable. The average cost of such a breach was estimated to be around $40 million.
A massive cryptocurrency mining campaign has been uncovered by security researchers at Kaspersky Lab – A campaign that has resulted in the creation of a vast network of devices infected with PowerGhost malware.
PowerGhost malware is being installed on all manner of devices including servers, endpoints, and POS devices. Once infected, each device generates a small amount of a cryptocurrency each day by using the device’s processing power to solve complex computational problems.
While a single device can be used to mine a few dollars of cryptocurrency each day, the returns are significant when the attackers are able to infect server farms and add hundreds of thousands of endpoints to their army of cryptocurrency mining slaves.
Once a device is infected, the cryptocurrency mining tool is downloaded and gets to work. A portion of an infected device’s processing power is then dedicated to mining cryptocurrency until the infection is identified and the malware is removed. PowerGhost malware also spreads laterally to all other vulnerable networked devices.
What makes PowerGhost such a difficult threat to detect is the fact that it doesn’t use any files, instead it is capable of mining cryptocurrency from the memory. PowerGhost is an obfuscated PowerShell script that includes various add-on modules, including the cryptocurrency mining component, mimikatz, and the DLLs required for the operation of the miner. Various fileless techniques are used to infect devices, ensure persistence, and avoid detection by anti-virus solutions. The malware also includes shellcode for the EternalBlue exploit to allow it to spread across a network to other vulnerable devices. Attacks are occurring through the exploitation of unpatched vulnerabilities and through remote administration tools.
PowerGhost malware is primarily being used in attacks on companies in Latin America, although it is far from confined to this geographical region with India and Turkey also heavily targeted and infections detected in Europe and North America.
Companies are being targeted. If a foothold can be gained in a corporate network, hundreds, thousands or tens of thousands of devices can be infected and used for cryptocurrency mining. The potential rewards for a successful attack on a medium to large enterprise is substantial.
In addition to cryptocurrency mining, Kaspersky Lab researchers note that one version of the PowerGhost malware is capable of being used for DDoS attacks, offering another income stream for the cybercriminal gang behind the campaign.
Prompt patching, disabling of remote desktop protocol, and the setting of strong complex passwords can help to protect against this PowerGhost malware campaign.
One of the world’s biggest shipping firms – Cosco – has experienced a ransomware attack that has seen its local email system and network telephone in the Americas taken out of action as the result of widespread file encryption.
The Cosco ransomware attack is believed to have been contained in the Americas region. As a precaution and to prevent further spread to other systems, connections to all other regions have been disabled pending a full investigation. A warning has also been issued to all other regions warning of the threat of attack by email, with the firm telling its staff not to open any suspicious email communications. IT staff in other regions have also been advised to conduct scans of their network with antivirus software as a precaution.
The attack started on Tuesday, July 24, and its IT infrastructure remains down; however, the firm has confirmed that that attack has not affected any of its vessels which continue to operate as normal. Its main business systems are still operational, although the operators of terminals at some U.S ports are experiencing delays processing documentation and delivery orders.
It would appear that the Cosco ransomware attack is nowhere near the scale of the attack on the world’s biggest shipping firm A.P. Møller-Maersk, which like many other firms, fell victim to the NotPetya attacks last year. In that case, while the malware appeared to be ransomware, it was actually a wiper with no chance of file recovery.
The attack, which affected more than 45,000 endpoints and 4,000 servers, is estimated to have cost the shipping company between $250 million and $350 million to resolve. All servers and endpoints needed to be rebuilt, and the firm was crippled for 10 days. In that case, the attack was possible due to an unpatched vulnerability.
Another major ransomware attack was reported last week in the United States. LabCorp, one of the leading networks of clinical testing laboratories in the United States, experienced a ransomware attack involving a suspected variant of SamSam ransomware. While the variant of ransomware has not been confirmed, LabCorp did confirm the ransomware was installed as a result of a brute force attack on Remote Desktop Protocol (RDP).
Labcorp was both quick to detect the attack and contain it, responding within 50 minutes, although 7,000 systems and 1,900 servers are understood to have been affected. It has taken several days for the systems to be brought back online, during which time customers have been experiencing delays obtaining their lab test results.
Several cybersecurity firms have reported that ransomware attacks are in decline, with cryptocurrency mining offering better rewards, although the threat from ransomware is still ever present and attacks are occurring through a variety of attack vectors – exploitation of vulnerabilities, brute force attacks, exploit kit downloads, and, commonly, through spam and phishing emails.
To protect against ransomware attacks, companies must ensure security best practices are followed. Patches must be applied promptly on all networks, endpoints, applications, and databases, spam filtering software should be used to prevent malicious messages from reaching inboxes, web filters used to prevent downloads of ransomware from malicious websites, and all staff should receive ongoing cybersecurity awareness training.
Additionally, systems should be implemented to detect anomalies such as excessing file renaming, and networks should be segmented to prevent lateral movement in the event that ransomware is deployed.
Naturally, it is also essential that data are backed up regularly to ensure recovery is possible without having to resort to paying the ransom demand. As the NotPetya attacks showed, paying a ransom to recover files may not be an option.
The National Bank of Blacksburg in Virginia has discovered just how important it is to have effective controls in place to protect against phishing. The bank suffered two costly phishing attacks in the space of eight months that have resulted in losses exceeding $2.4 million.
Phishing is the leading tactic used by cybercriminals to gain access to login credentials, steal data, and install malware. Emails are sent to employees with malicious attachments, which if opened, result in the installation of malware. Alternatively, links are sent in emails that direct employees to fraudulent websites where they are fooled into disclosing their login credentials.
The first attack on Blacksburg Bank took place on May 28, 2016. Malware was installed on its systems which gave the attackers access to the STAR Network – The system that manages debit card ATM activity. After gaining access to the STAR Network, the hackers were able to change account balances, remove security measures such as anti-theft and anti-fraud protections, conduct keystroke logging, and authorize withdrawals from customers’ accounts via ATMs.
In the two days that the hackers had access to the system, they were able to make withdrawals at hundreds of ATMs across the country and stole $569,648.24 from customers’ accounts. This was possible without stealing customers cards or using skimmers to create fake bank cards.
The malware was detected on May 30, 2016 and the attack was investigated by the computer forensics firm Foregenix which determined that the malware was installed as a result of an employee being duped by a phishing email.
Eight months later, on January 7, 2017, a similar attack occurred which involved cybercriminals gaining access to the STAR Network. Similarly, access was possible for two days, although in this case approximately $1.8 million was withdrawn from customers’ accounts. Verizon investigated the breach and concluded that access was gained as a result of an employee falling for a phishing scam.
The National Bank of Blacksburg holds an insurance policy against cyberattacks although its insurer, Everest National Insurance Company, has refused to cover the losses. Blacksburg is now suing its insurer for breach of contract.
What these incidents show is just how easy it is for major losses to be suffered as a result of employees falling for phishing scams and the importance of having robust anti-phishing measures in place.
There is no single solution that will provide total protection against phishing, although a good place to start is with an advanced spam filtering solution such as SpamTitan.
SpamTitan uses dual antivirus engines (Bitdefender and ClamAV) that provides superior protection against phishing and block emails containing malware and malware downloaders. The solution performs multiple checks on each incoming email to determine whether it is genuine, spam, or malicious, including standard checks of email headers, a Bayesian analysis on message content, and greylisting. Together, these controls ensure 99.97% of spam emails are detected and blocked, with a false positive rate of just 0.03%. Independent tests at Virus Bulletin have confirmed a 100% malware detection rate.
No anti-spam solution will block 100% of all spam and phishing emails so it is essential for employees to be trained how to recognize phishing emails. While it was once a best practice to provide annual training, with the volume of phishing emails now being sent and the increased sophistication of attacks, an annual training session is no longer sufficient.
Training needs to be ongoing, with regular training sessions scheduled throughout the year and employees conditioned through phishing simulation exercises. With effective spam filtering and employee security awareness training, the majority of phishing attempts can be thwarted.
In 2017, data breach mitigation costs fell year-on year; however, that appears to be a blip. The 2018 Cost of a Data Breach Study conducted by the Ponemon Institute (on behalf of IBM Security) has revealed data breach mitigation costs have risen once again.
The Ponemon Institute conducts the Cost of a Data Breach Study every year. For the 2018 study, the Ponemon Institute conducted interviews with 2,200 IT, data security, and compliance professionals from 477 companies in 15 countries, including the United States, United Kingdom, Germany, France, Canada, Brazil, Japan and Australia. The companies represented in the study came from a wide range of industry sectors. Each of those companies had experienced a data breach in the past 12 months.
Naturally, the larger the breach, the higher the cost of mitigation is likely to be. Breaches involving millions of records would naturally cost more to resolve than breaches of 50,000 records. Catastrophic data breaches – those involving millions of records – are not normally included in the study. This year was the first time that mega data breaches – those involving more than 1,000,000 records – were included, although they were treated separately.
The analysis of the main part of the study involved breaches ranging from 2,500 records to a little over 100,000 records. The average breach size was 24,615 records globally, 31,465 records in the United States, 22,800 records in the UK, and 19,200 records in Japan.
The costs associated with those data breaches was analyzed using the activity-based costing (ABC) methodology. The ABC methodology identified four process-related activities and assigned costs based on actual use. Those activities were Detection and Escalation, Post Data Breach Response, Breach Notifications, and Lost Business Cost. The analysis identified the average total cost of a data breach taking all four activity areas into account.
The study also revealed measures taken prior to the breach, during, and after, that can limit losses or increase data breach mitigation costs.
Average Data Breach Mitigation Costs Have Reached $3.86 Million
A data breach now costs an average of $3.86 million to revolve. Last year, the average cost of a data breach was $3.62 million. Data breach costs have therefore increased by 6.4% in the space of a year.
On average, per capita data breach mitigation costs rose by 4.8%, with a data breach costing, on average, $148 per record. Last year, the global average was $141 per record.
In addition to the rising cost, the severity of the breaches also increased, with the data breaches in this year’s sample impacting 2.2% more individuals on average.
Data breaches cost more to resolve in the United States than any other country. The average data breach mitigation costs in the United States is $7.91 million per breach. The lowest costs were in India, where the average breach cost was $1.77 million. The highest per capita costs were also in the United States at £233 per record.
Hackers and malicious insiders caused the most breaches and they were also the costliest to resolve at $157 per record. System glitches cost an average of £131 per record and breaches caused by human error cost the least at $128 per record.
Data breach costs varied considerably by industry sector, with healthcare data breach mitigation costs the highest by some distance at an average of $408 per record, followed by financial services breaches at $206 per record, services at $181 per record, and pharmaceutical industry breaches at $174 per record. Breaches in the education sector cost an average of $166 per record, retail industry breaches were $116 per record, and the lowest data breach mitigation costs were in the public sector at $75 per record.
The study of mega data breaches revealed a breach of 1 million records costs an estimated $39.49 million to resolve, while a breach of 50 million records costs an estimated $350 million. Since there were only 11 breaches of more than 1 million records in the sample it was not possible to accurately calculate the average cost of these breaches.
What Factors Affect Data Breach Mitigation Costs the Most?
For the study, 22 different factors were assessed to determine how they affected data breach mitigation costs. The most important cost saving measures that can be taken to reduce the cost of a data breach are having an incident response team ($14 less per record), widespread use of encryption ($13.1 less per record), BCM involvement ($9.3 less per record), employee training ($9.3 less per record), participation in threat sharing ($8.7 less per record) and use of an artificial intelligence platform ($8.2 less per record).
The main factors that increased data breach mitigation costs were third party involvement ($13.4 more per record), extensive cloud migration at the time of the breach ($11.9 more per record), compliance failures ($11.9 more per record), extensive use of mobile platforms ($10.0 more per record), lost or stolen devices ($6.5 more per record), and extensive use of IoT devices ($5.4 more per record).
With the cost of data breaches rising, more cyberattacks being conducted, and the likelihood of a breach being experienced now higher, it is essential not only for companies to implement layered security defenses, but also to make sure they are prepared for the worst.
Companies need to assume a breach will be experienced and policies and procedures need to be developed to deal with the breach when it happens. An incident response team should be prepared to spring into action to ensure everyone known what needs to be done when disaster strikes. The sooner a breach is identified and mitigated, the lower the breach mitigation costs will be.
There has been a major increase in cryptojacking attacks in recent months. Many cybercriminal gangs now favoring this method of attack over ransomware and other forms of malware and are taking advantage of the high value of cryptocurrencies.
As with ransomware attacks, cybercriminals need to install malicious code on computers. Instead of encrypting files like ransomware, the code is used to mine for cryptocurrency. Mining cryptocurrencies involves a computers CPU being used to solve complex computational problems, which are necessary for verifying cryptocurrency transactions and adding to the blockchain. In exchange for verifying transactions, the miner is paid a small amount for the effort.
Devoting one computer to the task of cryptocurrency mining could generate a few dollars a day. Using multiple computers for the task can generate a substantial return. The more computers that are used, the more blocks can be added to the blockchain and the greater the profits. When a network of cryptocurrency mining slave computers can be amassed, the profits can be considerable. According to Kaspersky Lab, one cryptojacking gang that focusses on infecting enterprise servers and spreading the malicious code using NSA exploits, has generated around 9,000 Monero, which equates to $2 million.
Not all computers are suitable for mining cryptocurrency. One cybercriminal gang has got around this by developing malware that can decide whether to deploy a cryptocurrency miner or ransomware, with the decision based on the processing power of the computer. If its not suitable for use mining cryptocurrency, ransomware is deployed. This tactic helps maximize profits after compromising a device.
The use of cryptocurrency miners increased sharply last year as the value of cryptocurrencies started to soar. The price of those cryptocurrencies may have fallen, but cryptojacking attacks are still on the rise. The volume of new cryptojacking malware variants has also increased considerably over the past few months. Figures from McAfee indicate the number of cryptojacking malware variants increased by a staggering 1,189% in the first three months of 2018 alone, rising from around 400,000 malware variants to more than 2.9 million.
Over the same time frame, there has been a fall in the number of ransomware attacks. In Q1, ransomware attacks fell by around 32%, indicating threat actors who previously used ransomware to make money have changed their tactics and are now using cryptocurrency miners.
Ransomware attacks falling by a third is certainly good news, although the threat from ransomware cannot be ignored. Steps must be taken to prevent the installation of the file encrypting code and good backup practices are essential to ensure files can be recovered in the event of an attack. Certain industries face a higher risk of ransomware attacks than others, such as the healthcare industry, where attacks are still rife.
Cryptojacking attacks are more widespread, although the education sector has proven to be a major target. Many mining operations have been discovered in the education sector, although it is unclear whether these mining operations are legitimate, computers are being used by students to mine cryptocurrency, or if educational institutions are being targeted.
One thing is clear. As the value of cryptocurrencies rose, the number of mining attacks increased. That suggests that should prices fall, cybercriminals will switch to other types of attacks, and there could be a resurgence in ransomware attacks.
It could be argued that the installation of cryptocurrency mining malware on a computer is far less of a problem than ransomware or other forms of malware. When the CPU is mining cryptocurrency, the user is likely to find their computer somewhat sluggish. This can result in a drop in productivity. Heavy processing can also cause computers to overheat and hardware damage can result.
Cryptojacking malware is usually installed by a downloader, which can remain on a computer. If the profits from mining cryptocurrency fall, new malware variants could easily be downloaded in its place. Cryptocurrency mining malware can also be bundled with other malware variants that steal sensitive information. Cryptojacking attacks are therefore a major threat.
Protecting against cryptojacking attacks involves the same security controls that are used to block other forms of malware. Cryptojacking malware can be installed by exploiting vulnerabilities so good patch management is essential. Spam and phishing emails are used to install malware downloaders, so an advanced spam filtering solution is a must. Web filters can prevent web-based mining attacks and malware downloads and offer an important extra layer of protection. It is also important not to neglect end users. Security awareness training can help to eradicate risky behaviors.
Additionally, security audits should be conducted, first to scan for the presence of cryptojacking malware, which includes searching for anomalies that could indicate the presence of the malware. Those audits should include servers, end points, POS systems, and all other systems. Any system connected to the network could potentially be used for mining cryptocurrency.
Rakhni ransomware, a malware variant first detected in 2013, has spawned many variants over the past three years and is still an active threat. Rakhni ransomware locks files on an infected device to prevent the user from accessing their data. A ransom demand is issued and if payment is made, the attackers will supply the keys to unlock the encryption. If the ransom is not paid the files will remain encrypted. In such cases, the only option for file recovery is to restore files from backups.
Now the developers of Rakhni ransomware have incorporated new functionality. Checks are performed on an infected device to determine whether it has sufficient processing power to be used as a cryptocurrency mining slave. If so, cryptocurrency mining malware will be downloaded. If not, ransomware will be deployed.
This new development should not come as a major surprise. The massive rise in the value of many cryptocurrencies has made mining cryptocurrencies far more profitable for cybercriminals than ransomware. When ransomware is installed, many victims choose not to pay and instead recover files from backups. Infection is no guarantee that a payment will be received. If a cryptocurrency miner can be installed, it gets straight to work generating money for the attackers. Ransomware attacks are still a major threat, although many cybercriminals have switched their operations to mining cryptocurrencies. In fact, cryptocurrency mining malware attacks are now much more common than ransomware attacks.
However, not all computers have sufficient CPU processing power to make cryptocurrency mining worthwhile, so the method used by the threat actors behind Rakhni ransomware helps them maximize their profits.
The new Rakhni ransomware campaign was detected by researchers at Kaspersky Lab. The malware used is Delphi-based and is being distributed in phishing emails containing a Microsoft Word file attachment.
The user is advised to save the document and enable editing. The document contains a PDF file icon which, if clicked, launches a fake error message suggesting the DLL file required to open the PDF file has not been found. The user needs to click on the OK box to close the error message.
When the error box is closed, the malware performs a series of checks on the machine to identify the processes running on the device and assesses those processes to determine if it is running in a sandbox environment and the likelihood of it being able to run undetected. After these checks have been performed the system is assessed to determine its capabilities.
If the machine has more than two processors and does not have a Bitcoin folder in the AppData folder, a cryptocurrency miner will be installed. The cryptocurrency miner uses fake root certificates which show the program has been issued by Microsoft Corporation to help disguise the miner as a trusted application.
If a Bitcoin folder does exist, certain processes will be stopped, and Rakhni ransomware will be downloaded and run. If there is no Bitcoin folder and only one processor, the malware will use its worm component and twill attempt to spread to other devices on the network where the process starts over.
Advanced anti-virus software can provide protection against this attack, while spam filtering solutions can prevent the phishing emails from being delivered to end users. Businesses should also ensure that their employees are made aware of the risk of these types of attacks through security awareness training. Employees should be instructed never to open attachments in emails from unknown senders and taught the warning signs of a potential attack in progress. Naturally, good data backup practices are essential to ensure that if all other controls fail, files can be recovered without paying a ransom.
A major Children’s Mercy Hospital phishing attack has highlighted the importance of implementing effective spam filtering controls and the need to provide security awareness training to end users.
Phishing is a method of fraudulently obtaining sensitive information through deception. While attacks can occur over the telephone, via social media sites, or through text messages and chat platforms, the most common attack vector is email.
Convincing emails are sent to end users urging them to open an email attachment or to click on a malicious link. Attachments are used to install malware, either directly through malware attached to the email, or more commonly, using macros or other malicious code in documents which download scripts that in turn download the malicious payload.
In the case of embedded hyperlinks in emails, they typically direct an end user to a website that asks them to login. The website could ask for their email credentials, appear to be a Google login box, Dropbox login page, or other file sharing platform. Disclosing login credentials on that webpage sends the information to the attackers. These login pages are convincing. They look exactly like the sites that they are spoofing.
That was the case with the Children’s Mercy Hospital phishing attack. The Kansas City, MO, hospital received several phishing emails which directed employees to fake login pages on criminally-controlled websites.
The phishing attack occurred on or shortly before December 2, 2017. On Dec 2, Children’s Mercy’s security team identified authorized access to two employees’ email accounts. Access to the accounts was blocked the same day and the passwords were reset. Two weeks later, on December 15 and Dec 16, two further email accounts were accessed by unauthorized individuals. Again, unauthorized access was detected and blocked the same day. A fifth email account was accessed on January 3, 2018 with access blocked the following day.
The prompt action in response to the Children’s Mercy phishing attack limited the potential for those email accounts to be abused. When criminals gain access to email accounts they often use them to send further phishing emails. Since those emails come from a legitimate email account, the recipients of the messages sent from that account are more likely to open the emails as they come from a trusted source. That is why business email compromise scams are so effective – because employees trust the sender of the email and take action as requested in the belief that they are genuine communications.
In the case of the Children’s Mercy phishing attack, the criminals acted quickly. Following a forensic investigation into the attacks, Children’s Mercy discovered on January 19, 2018, that even though access to the accounts was promptly blocked, the attackers had successfully downloaded the mailboxes of four of the five employees. The messages contained a wide range of protected health information (PHI) of 63,049 patients.
The PHI included information such as name, gender, age, height, weight, BMI score, procedure dates, admission dates, discharge dates, diagnosis and procedure codes, diagnoses, health conditions, treatment information, contact details, and demographic information.
While Social Security numbers, insurance information, and financial data were not obtained – information most typically required to commit fraud – such detailed information on patients could be used in impersonation attacks on the patients. It would be quite easy for the attackers to pretend they were from the hospital and convince patients to provide their insurance information for example, which could then be used for medical identity fraud.
Due to the scale of the attack and number of emails in the compromised accounts, it has taken a considerable time to identify the individuals affected. The Kansas City Star reports that some patients are only just being notified.
In response, the hospital implemented 2-factor authentication and other technical controls to prevent further attacks.
2-factor authentication is an important security measure that provides protection after a phishing attack has occurred. If login credentials are supplied, but the location or the device used to access the account is unfamiliar, an additional method of authentication is required before access to the account is granted – a code sent to a mobile phone for example.
Two of the most effective security controls to prevent credential theft via phishing are spam filters and security awareness training.
An advanced spam filter is an essential security measure to block phishing attacks. The changing tactics of cybercriminals means no spam filtering solution will be able to block every single phishing email, although SpamTitan, a highly effective spam filtering solution with advanced anti-phishing protections, blocks more than 99.97% of spam and malicious emails to ensure they do not arrive in end users’ inboxes.
Security awareness training helps to prevent employees from clicking on the small percentage of messages that get past perimeter defenses. Employees need to be trained to give them the skills to identify phishing attempts and report them to their security teams. An ongoing training program, with phishing simulation exercises, will help to condition employees to recognize threats and respond appropriately. Over time, phishing email detection skills will improve considerably.
An effective training program can limit the number of employees that respond to phishing attacks, either preventing the attackers from gaining access to email accounts or severely limiting the number of employees who respond and disclose their credentials.
The Children’s Mercy phishing attack is one of many such attacks on healthcare organizations and businesses, and as those attacks increase and more data is obtained by criminals, implementing advanced phishing protections has never been more important.

A recent survey of members of the Spiceworks community investigated the use of web filtering by businesses and the effect of web filtering on security and productivity. The survey was conducted on 645 members of its professional network based in the United States and Europe from a wide range of industries including healthcare, finance, and manufacturing.
Web filtering is an important security control that can provide an additional layer of protection against malware and phishing attacks. Web filters can also be used to improve the productivity of the workforce by limiting access to certain types of websites. The Internet can help to improve productivity, although it can also prove a temptation for workers and a major distraction. When a complicated report must be produced, cat videos can be especially tempting.
The survey sought to find out more about the effect of web filtering on security and productivity, how web filters are being used by businesses, the amount of time that employees are wasting on personal Internet use, and the types of websites that businesses are blocking to improve productivity.
Web Filtering is Used by the Majority of Businesses
The survey revealed widespread use of web filters by businesses. Overall, 89% of organizations have implemented a web filter and use it to block certain types of productivity-draining Internet content such as social media websites, dating sites, gambling sites, and streaming services.
The larger the business, the more likely it is that Internet content control will be implemented. 96% of large organizations (1,000+ employees) use web filters to limit employee Internet activity. The percentage drops to 92% for mid-sized businesses (100-999 employees) and 81% for small businesses (up to 99 employees). 58% of organizations said they use a web filtering solution to monitor Internet use by employees.
The survey asked IT professionals who have not implemented a web filtering solution how many hours they think employees are wasting on personal Internet use each week. 58% of employees were thought to waste around 4 hours a week on personal internet use and around 26% of workers spend more than 7 hours a week on non-work-related websites. Without a web filter, most employees will spend around 26 days a year on personal Internet use which, based on average earnings, corresponds to $4,500 paid per employee to slack off on the Internet.
Compare that to the figures for companies that restrict access to at least one category of website and the percentages fall to 43% of employees spending more than 4 hours a week on personal Internet use and 18% who spend more than 7 hours a week on non-work-related websites. The biggest drain of productivity was social media sites, with the figures falling to 30% of employees spending more than 4 hours a week on non-work-related sites when social media sites were blocked.
What are the Most Commonly Blocked Websites?
How are web filters used by businesses and what types of website are most commonly blocked? Unsurprisingly, the most commonly blocked websites were illegal sites and inappropriate sites (pornography for example). Both categories were blocked by 85% or organizations.
After that, the most commonly blocked category of content was dating sites – blocked by 61% of organizations. Businesses are more permissive about the use of social media websites, with only 38% blocking those sites, while instant messaging services were blocked by 34% of organizations. Even though they can be a major drain on bandwidth, streaming services were only blocked by 26% of companies.
What are the Main Reasons for Implementing a Web Filter?
While Internet content control – in some form – has been implemented by the majority of companies, it was not the main reason for implementing a web filter. Money could be saved by improving productivity, but the biggest reason for implementing a web filter was security. 90% of businesses said they had implemented a web filter to protect against malware and ransomware infections and with good reason: Inappropriate Internet access leads to data breaches.
38% of surveyed companies said they had experienced a data breach in the past 12 months as a result of employees visiting non-work-related websites, most commonly webmail services (15%) and social media sites (11%).
Other reasons for implementing a web filter were to block illegal activity (84%) and discourage inappropriate Internet access (83%). 66% of organizations use a web filter to avoid legal liability while 57% used web filters to prevent data leakage and block hacking.

A database of U.S. consumer information has been left unsecured online by the marketing firm Exactis. At 340 million records, this is the largest data breach of 2018.
The Largest Data Breach of 2018 by Some Distance
You will probably be unaware of the existence of the Palm Coast, FL-based data broker Exactis, but chances are the firm has heard of you. The firm holds 3.5 billion consumer, business and digital records while its email database contains 500 million consumer emails and 16 million business emails.
One database maintained by the firm contains around 340 million records, including 230 million consumer records and 110 million records of businesses. That database was recently discovered to have been left exposed on the Internet. The database could be accessed without any authentication. Anyone who knew where to look would have been able to access the database. At least one person did.
Security researcher Vinny Troia who runs NightLion Security, a New York consultancy firm, was searching online for instances of Elasticsearch databases. Troia was curious about the security of the databases as they are designed to be easily queried over the Internet. Troia searched for the databases using the search engine Shodan. Shodan is a search engine that allows people to find specific types of computers that are connected to the Internet.
Troia discovered more than 7,000 Elasticsearch databases that were visible on publicly accessible servers with U.S. IP addresses and set about determining which, if any, had data exposed on the Internet. He wrote a script that queried those databases and searched for keywords that would indicate they contained sensitive information – fields such as date of birth.
2 Terabytes of Data Exposed
One database stood out due to the amount of data it contained – around 2 terabytes of data. The database was not protected by a firewall and could be accessed without authentication. The database was discovered to contain huge numbers of detailed records about consumers. Troia noted, “It seems like this is a database with pretty much every U.S. citizen in it… it’s one of the most comprehensive collections I’ve ever seen.”
He discovered the records contained up to 150 data fields, with highly detailed information on consumers including names, addresses, phone numbers, email addresses and descriptions of the person, including information such as the estimated value of their home, hobbies, mortgage provider, ethnic group, whether the individual owns any stock, their religion, if they have made political donations, number of children, people in the household, whether they are smokers, if they own any pets…the list goes on and on.
While the database did not contain Social Security numbers or financial information, the data could be used by scammers in spear phishing campaigns, telephone scams and social engineering attacks. Around half the records contained email addresses, making it particularly valuable to spammers.
Troia said he is certainly not the only person who has searched for Elasticsearch databases, and the database was easy to find using Shodan: A popular search engine with white hat and black hat hackers. It is unknown whether anyone else found the database, but Troia explains that it would not be hard for anyone to find it. He could not be sure how long the database had been exposed online, but said it was at least 2 months.
After identifying an IP address which he believed belonged to the owner, Troia contacted two hosting companies, one of which notified Exactis. Troia also alerted the FBI. Exactis made contact with Troia and the database has now been secured and is no longer accessible.
At 340 million records, this the largest data breach of 2018 and one of the largest breaches ever discovered. The breach is more than twice the size of the Experian data breach of last year, although not on the scale of the Yahoo data breach that contained around 3 billion records. However, the types of information exposed potentially make the breach far more serious than Yahoo’s.
A database containing such detailed information on consumers should not have been left exposed. Safeguards should have been in place to alert the company that security protections had either been turned off or had not been implemented.
This security breach certainly stands out in terms of scale, but it is sadly only one of many that have been identified in recent months involving databases left freely accessible over the Internet.
The FBI has published its 2017 Internet Crime Report, which details the main types of online crime reported to its Internet Crime Complaint Center (IC3).
In 2017, businesses and consumers reported 301,580 incidents to IC3 and more than $1.4 billion was lost to cybercriminals. Of course, these are only reported losses. Many Internet crimes go unreported, so the true losses are likely to be substantially higher.
2017 saw more complaints of Internet crime than any other year since 2013 when the reports first started to be published.
Identity theft and corporate data breaches often make the headlines, although by far the biggest area of criminal activity are business email compromise (BEC) scams – or email account compromise (EAC) when the scams target individuals.
Business Email Compromise Scams – The Main Cause of Losses in 2017
More than three times as much money was lost to BEC and EAC scams than the next highest cause of losses: confidence fraud/romance scams. In 2017, the reported losses from BEC/EAC scams was $676,151,185.
Business email compromise and email account compromise scams involve the use of a compromised email account to convince individuals to make transfers of funds to accounts controlled by criminals or to send sensitive data via email.
BEC scams usually start with compromising the email account of the CEO, CFO or another board member – which is why this type of scam is also known as CEO fraud. Access to the executive’s email account is gained via brute force guessing of passwords or, most commonly, social engineering techniques and phishing scams.
Once access to the email account is gained, an email conversation is initiated with another member of the workforce, typically an individual responsible for making wire transfers. That individual is instructed to make a transfer to a new bank account – that of the attacker. Alternatively, the data of employees is requested – W2 Forms – or other sensitive company information. These scams often involve large transfers of funds. In 2017 there were 15,690 such scams reported to IC3, making the average loss $43,094.
Phishing Extensively Used in Internet Crime
Phishing, vishing, smishing and pharming were grouped together. They ‘only’ resulted in losses of $29,703,421, although the losses from these crimes are difficult to calculate accurately. The losses associated with phishing are grouped in many other categories. BEC scams often start with a phishing attack and research from Cofense suggests 91% of corporate data breaches start with a phishing email.
The 2017 Internet Crime Report reveals the extent to which phishing is used in cyberattacks. There were 25,344 phishing incidents reported to IC3 in 2017 – the third highest category of Internet crime behind non-payment/non-delivery and personal data breaches. Many personal data breaches start with a phishing email.
Ransomware Attack Mitigation Proves Expensive
In addition to the threat of BEC attacks, the FBI’s 2017 Internet Crime Report warns of the threat from ransomware. Ransomware only resulted in reported losses of $2.3 million and attracted 1,783 complaints, although it is worthy of a mention due to the considerable disruption that attacks can cause. The reported losses – in terms of the ransoms paid – may be low, but actual losses are substantially higher. The ransomware attack on the City of Atlanta in April 2018 saw a ransom demand of $52,000 issued, although the actual cost of mitigating the attack was reported to be at least $2.7 million in April. However, in June 2018, city Information Management head Daphney Rackley indicated a further $9.5 million may be required over the coming year to cover the cost of mitigating the attack.
Tech Support Fraud Losses Increased by 90%
Another hot topic detailed in the 2017 Internet Crime Report is tech support fraud – This is a widespread scam where individuals are fooled into thinking they have a computer problem such as a virus or malware installed, when they do not. Calls are made warning of detected malware, and users are directed to malicious websites via phishing emails where pop-up warnings are displayed, or screen lockers are used.
These scams usually require the victim to pay the scammer to remove a fictitious infection and provide them with remote access to a computer. In addition to the scammers charge for removing the infection, sensitive data such as usernames, passwords, Social Security numbers, and bank account information are often stolen. 2017 saw a 90% increase in losses from tech support scams.
Protecting Against Internet Crime
One of the most important defenses for businesses to implement to protect against the leading cause of financial losses is an advanced spam filtering solution. Business email compromise scams often start with a phishing email and effective spam filtering will reduce the potential for email accounts to be compromised. Ransomware and malware are also primarily distributed via email. An advanced spam filter such as SpamTitan will block 100% of all known malware and prevent malicious messages from being delivered to inboxes.
Security awareness training is also essential. Malicious messages will make it past spam filtering solutions on occasion, so it is important for all end users to be prepared for malicious messages and taught security best practices. Training should be provided to every individual in the company with a corporate email account or access to an Internet facing computer, including board members.
A web filtering solution is also an important consideration. A web filter is an additional anti-malware control that can be used to prevent employees from visiting malicious websites – either via links in emails, redirects, or through general web browsing. A web filter, such as WebTitan, will block ransomware and malware downloads and prevent end users from accessing the types of phishing websites used to initiate BEC attacks.
These three cybersecurity measures should be part of all organizations’ cybersecurity defenses. They will help to prevent businesses from being included in next year’s FBI Internet Crime Report.
UK users are being targeted with a fake WannaCry ransomware alert threatening file encryption if a ransom demand is not paid.
Fraudsters Claim WannaCry is Back!
In May last year, WannaCry ransomware attacks brought many companies to a standstill, with the UK’s National Health Service (NHS) a notable victim. Now, a little more than a year later, a new WannaCry ransomware campaign is being run, or so the sender of a batch of phishing emails claims.
Email recipients are told “WannaCry is back!” and are warned that their devices have been hacked and ransomware has been installed.
Email recipients are warned that the threat actors have perfected their ransomware and this time around antivirus software and firewalls will not prevent file encryption. Further, recovery will not be possible if the ransom is not paid.
Failure to pay, or any attempt to try to remove the ransomware without paying the ransom demand will result in permanent file deletion. Further, the ransomware can propagate and infect the local network, cloud data, and remote devices, regardless of operating system.
Email recipients are told that the ransomware has already been deployed and payment of a ransom of 0.1 Bitcoin – Around $650 – must be made to stop the attack. Email recipients are given just 24 hours to pay the ransom before data are permanently deleted.
The email is signed by WannaCry-Hack-Team, and so far, more than 300 copies of the message have been reported to the UK government’s National Fraud and Cyber Crime Reporting Centre, Action Fraud.
A Phishing Scam that Preys on WannaCry Fears
There are some signs that the email is not a genuine threat, and instead is just preying on fears about another WannaCry style attack.
Ransomware attackers encrypt data then ask for a ransom to unlock files. They do not send a warning saying they will encrypt data if a ransom is not paid. That tactic may be used by some DDoS attackers, but not by ransomware threat actors.
Email recipients are told that this version of WannaCry will work on “any version of Windows, iOS, Android, and Linux.” The original version of WannaCry took advantage of a vulnerability in Windows Server Message Block. WannaCry only affected vulnerable Windows devices that had not been patched. The ransomware was not a threat on other operating systems.
Phishing campaigns often include spelling mistakes in the subject line and message body and this email is no different. The subject line is – “Attantion WannaCry”.
This is simply a phishing campaign that attempts to extort money from the recipient. No ransomware has been installed and the attackers cannot encrypt any files.
If you receive such a message threatening file encryption unless you pay a ransom, report the message to Action Fraud (UK), US-CERT (email@example.com) in the United States, or the government Fraud and Cyber Crime agency in your country of residence and delete the email and do not pay any Bitcoin ransom.
Of course, not all ransomware threats are as benign as this and many attackers will be able to encrypt your data. To protect against real ransomware threats ensure you create multiple backups of your files, deploy a spam filtering solution, ensure your operating system and all software are kept up to date, and keep your anti-virus protection up to date.
A new Adidas phishing scam has been detected that offers free shoes and money. The messages claim that Adidas is celebrating its 69th anniversary and is giving 2,500 lucky customers a free pair of Adidas sneakers and a free $50 a month subscription.
The scam is targeting users on mobile devices in specific locations. If the user clicks the link in the message and is determined not to be using a mobile device, they will be directed to a webpage that displays a 404 error. The scam will also only run if the user is in the United States, Pakistan, India, Norway, Sweden, Nigeria, Kenya, Macau, Belgium or the Netherlands.
Provided the user is on a mobile device and located in one of the targeted countries, a series of four questions will be asked. The responses to the questions are irrelevant as all users will be offered a “free” pair of sneakers after answering the four questions.
In order to be able to claim the prize, users must share the offer with their contacts on WhatsApp. Regardless of whether the user does this, they will be directed to another webpage where they are asked further questions and are finally offered a “free” pair of sneakers worth $199.
There is another catch. In order to claim their free sneakers, the user must pay $1. The user is advised that they will also be charged $49.99 a month for the subscription at the end of the month if they do not cancel. The user is told they can cancel at any point.
On the payment screen the user is told that the payment will be processed by organizejobs.net. Proceeding with the payment will see the user charged $1, followed by the subscription cost of $49.99 in 7 days.
The campaign is being run on WhatsApp, although similar scams have been conducted via email and SMS messages. Several variations along the same theme have also been identified using different shoe manufacturers.
The link supplied in the WhatsApp message appears to be genuine, using the official domain for the country in which the user is located. While the domain looks correct, this is an example of a homoglyph attack. Instead of the domain adidas.de, the i is replaced with a vertical line – a homoglyph attack.
These types of scams are commonplace. Homoglyph scams take advantage of the ability to use non-ASCII characters in domain names. Similar scams use a technique called typosquatting – where domains closely matching real brand names are registered: Incorrect spellings for instance, such as “Addidas” instead of Adidas, or with an i replaced with a 1 or an L.
In this case, the attackers appear to be earning a commission for getting users to sign up, although disclosing debit and credit card details could easily see the information used to run up huge bills or drain bank accounts.
There are various warning signs indicating this is an Adidas phishing scam. Close scrutiny of the domain will reveal it is incorrect. The need to share the message to contacts is atypical, being notified of a charge after being told the shoes are free, the failure to ask the user to choose a pair of shoes or even select their size, and an odd domain name is used to process payment. However, even with these tell-tale signs that the offer is not genuine, this adidas phishing scam is likely to fool many people.
Be warned. If you receive any unsolicited WhatsApp message offering you free goods, assume it is a scam.
A new type of ransomware attack could be on the horizon. The attack method, termed ransomcloud, was developed by a white hat hacker to demonstrate just how easy it is to launch an attack that results in cloud-based emails being encrypted.
A successful attack will see the attacker gain full control of a cloud-based email account, allowing them to deploy a ransomware payload that encrypts all emails in the account. This method could also be used to gain full control of the account to use for spamming and other malicious purposes.
The attack works on all cloud-based email accounts that allow third party applications account access via OAuth, which includes Gmail and Office 365 accounts.
The ransomcloud attack starts with a phishing email. In this example, the message appears to have been sent by Microsoft offering the user the opportunity to sign up and use a new email spam filtering service called AntiSpamPro. The email includes the Microsoft logo and appears to be a new Microsoft service that provides the user with better spam protection.
In order to take advantage of this service, the user is required to click a hyperlink in the email to give authorization for the new service to be installed. Clicking the link will result in a popup window appearing that requires the user to authorize the app to access their email account.
Such a request is perfectly reasonable, as an app that offers protection against spam would naturally require access to the email account. Emails would need to be read in order for the app to determine whether the messages are genuine or spam. Clicking on ‘accept’ would give the attacker full control of the email account via an OAuth token. If access is granted, the user loses control of their email account.
In this example, ransomware is installed which encrypts the body text of all emails in the account. An email then appears in the inbox containing the ransom note. The user is required to pay a ransom to regain access to their emails.
Additionally, the attacker could claim the email account as their own and lock the user out, send phishing emails to all the user’s contacts, access sensitive information in emails, use email information to learn about the individual to use in future attacks such as spear phishing campaigns to gain access to their computer.
The ransomcloud attack method is astonishingly simple to pull off and could be adopted by cybercriminals as a new way of extorting money and gaining access to sensitive information.

A recent study of commonly used passwords by Dashlane/Virginia Tech has revealed some of the worst passwords of 2018.
For the study, Virginia Tech researchers provided Dashlane with an anonymized copy of 61.5 million passwords. The password list was created from 107 individual lists of passwords available on forums and in data archives, many of which have come from past data breaches.
The analysis of the list revealed many common themes. These include the names of favorite sports teams: In the UK, common password choices were liverpool, chelsea and arsenal – the leading soccer teams in the premier league.
Popular brand names were also chosen, such as cocacola, snickers, mercedes, skittles, mustang, and playboy. MySpace and LinkedIn were also common choices, alarmingly, to secure accounts on those sites.
Bands and movie references were often used, with Spiderman, superman, starwars, and pokemon all common choices as were expressions of frustration – a**hole, bull****, and f***you were often chosen.
The Dashlane report shows that despite warnings about the risk of using easy-to-remember passwords, end users are still choosing weak passwords. One particularly worrying trend is the use of seemingly secure passwords, which are anything but secure.
1q2w3e4r5t6y and 1qaz2wsx3edc may appear to be relatively secure passwords; however, how they are created makes them easy to guess. They are certainly better than “password” or letmein” but not by much.
The passwords are created by a process that Dashlane calls password walking – the use of letters, numbers, and symbols next to each other on a keyboard. Simpler variations on this theme are qwerty and asdfghjk. To get around password rules, the same technique is used with the incorporation of capital letters and symbols.
The study shows that even though many companies require end users to set strong passwords, employees ignore password advice or choose passwords that pass security checks but are really not that secure.
What Makes a Good Password?
A good password will not be in the dictionary, will not use sequential numbers or be created by walking fingers along a keyboard. Brand names and locations should also be avoided. Passwords should be a minimum of 8 characters and should be unique – never used before by the user, and never reused on a different platform.
Passwords should include at least one capital letter, lowercase letter, symbol and number. If all lowercase letters are used, each letter in the password could be one of 26 letters. Add in capitals and the possible options double to 52. There are 10 digits, increasing the options to 62, and let’s say 32 special characters, bringing the total up to 94 options. With so many options and possible combinations, randomly generated passwords are particularly difficult to guess. However, randomly generated passwords are also particularly difficult to remember.
Recently, that problem has been recognized by the National Institute of Standards and Technology (NIST), which has revised its advice on passwords (See special publication 800-63B).
While the use of random strings of characters and symbols makes passwords particularly difficult to guess and more resilient to hackers’ brute force password guessing tactics, end users have trouble remembering their passwords and that leads to particularly risky behaviors such as writing the password down or storing it in a browser.
NIST now suggests the use of longer passphrases rather than passwords – Iboughtacarwithmyfirstpaypacket or ifihadahorseIwouldcallitDave– for example. Passphrases are more user-friendly and easier to remember, but are still secure – provided a sufficient number of characters are used. If passphrases are encouraged rather than difficult to remember passwords, end users will be less likely to set passwords that meet strong password guidelines but are not particularly secure – LetMeIn! for example.
The minimum number of characters can be set by each organization, but rather than restricting the characters at 16, companies should consider expanding this to at least 64. They should also accept all printable ASCII characters, including spaces, and UNICODE characters.
Since some end users will attempt to set weak passwords, it is important to incorporate controls that prevent commonly used passwords from being chosen. Each password choice should be checked against a blacklist before it can be set.
A new spam campaign has been identified that uses Excel Web Query files to deliver malware. In this case, the .iqy files are used to launch PowerShell scripts that give the attackers root access to a device. .iqy files are not usually blocked by spam filters, making the technique effective at silently delivering malware.
The spam emails are being delivered via the Necurs botnet. Three spam campaigns have been detected by Barkly that use these attachments, although further campaigns are almost certain to be launched.
Excel Web Query files obtain data from an external source and load it to Excel. In this case, the external data is a formula which is executed in Excel. The formula is used to run PowerShell scripts which, in at least one campaign, downloads a Remote Access Trojan (RAT) called FlawedAmmyy Admin – a tweaked legitimate remote administration tool that gives the attacker full control of a computer, allowing any number of malicious programs to be installed.
The emails masquerade as purchase orders, unpaid invoices, and scanned documents – Common themes used in spam emails to deliver malware. These spam email campaigns often use Word documents with malicious macros. Macros are usually disabled by default. Through security awareness training, end users have been conditioned not to enable macros on documents from unknown senders, thus preventing malware downloads.
Since most end users will not be used to receiving .iqy files, these attachments should arouse suspicion. Microsoft has also built in warnings to prevent these files from being run by end users. If an end user attempts to open one of these files it will trigger a warning alerting the user that the file may not be safe as it enables an external connection. The end user would be required to click enable before the connection is made and data is pulled into Excel. A second warning would then be displayed, again requiring authorization. Only if both warnings are ignored will the script be allowed to run that downloads the malicious payload.
There are two steps you can take to protect your endpoints and networks from these types of attacks. The first is to configure your email spam filter to quarantine any emails containing .iqy attachments. SpamTitan allows certain attachment types to be blocked such as executable files and iqy files. You can set the policy to quarantine, reject, or delete the emails. Since these types of files are not usually sent via email, rejecting the messages or deleting them is the safest option.
You should also cover the use of these files in your security awareness training sessions and should consider sending an email alert to end users warning them about the threat.
Further information on steps you can take to prevent malware infections spread via email can be found in our anti-spam tips page. You can find out more about the capabilities of SpamTitan by calling the sales team:
World Cup 2018 phishing scams can be expected over the coming weeks. There has already been a spike in World Cup related phishing emails and many malicious World Cup-themed domains have been registered.
World Cup 2018 Phishing Scams Detected!
The World Cup may be two weeks away, but interest in the soccer extravaganza is already reaching fever pitch. The World Cup is watched by billions of people around the world, and there are expected to be around 5 million soccer fans expected to travel to Russia to see the matches live between June 14 to July 15. With such interest in the sporting event it should be no surprise that cybercriminals are poised to take advantage.
Kaspersky Lab has already detected several World Cup 2018 phishing scams, with many of the early scams using emails to direct soccer fans to malicious websites offering the opportunity to buy tickets for the games.
Fake Tickets and Fake Touts
With tickets for the big matches scarce and demand outstripping supply, many fans are turning to touts to secure tickets to the big matches. Steps have been taken by FIFA to make it harder for ticket touts to operate, such as only allowing one ticket for a game to be purchased by any football fan. That individual is also named on the ticket. However, it is still possible for individuals to purchase tickets for guests and touts are taking advantage. The price for guest tickets is extortionate – up to ten times face value – and that price will likely rise as the event draws closer.
Such high prices mean the opportunity of snapping up a cheaper ticket may seem too good to miss. However, there are plenty of scammers who have registered websites and are posing as touts and third parties that have spare tickets.
Purchasing a ticket through any site other than the official FIFA is a tremendous risk. The only guarantee is that the price paid will be substantially higher, but there are no guarantees that a ticket will be sent after payment is made. Even if a ticket is purchased from an unofficial seller, it may turn out to be a fake. Worse, paying with a credit or debit card could see bank accounts emptied.
Kaspersky Lab detected large numbers of malicious domains set up and loaded with phishing pages to take advantage of the rush to buy tickets ahead of the tournament. The websites are often clones of the official site.To add credibility, domains have been purchased that include the words worldcup2018 and variations along that theme. Cheap SSL certifications have also been purchased, so the fact that a website starts with HTTPS is no guarantee that a site is legitimate. Tickets should only be purchased through the official FIFA website.
Why pay a high price for a ticket when there is a chance of obtaining one for free? Many competition-themed World Cup 2018 phishing emails have been detected. These emails are sent out in the millions offering soccer fans the change to win a free ticket to a match. To be in with a chance, the email recipient is required to register their contact details. Those details are subsequently used for further phishing and spamming campaigns. Stage two of the scam, where the ‘lucky’ registrant is told they have one tickets, involves opening an email attachment, which installs malware.
Notifications from FIFA and Prizes from FIFA World Cup 2018 Partners
Be wary of any communications from FIFA or any company claiming to be an official World Cup Partner. Kaspersky Lab has detected several emails that appear, at face value, to have been sent by FIFA or its World Cup 2018 partners. These emails usually request the recipient to update their account for security reasons.
Visa is one brand in particular that is being spoofed in World Cup 2018 phishing emails for obvious reasons. Fake security alerts from Visa require credit card credentials to be entered on spoofed websites. If any security alert is received, visit the official website by typing in the official domain into the browser. Do not click the links contained in the emails.
Cheap Travel Accommodation Scams
Airline tickets to cities staging World Cup matches may be difficult to find, and with more than 5 million fans expected in Russia for the World Cup, accommodation will be scarce. Scammers take advantage of the scarcity of flights and accommodation and the high prices being charged and offer cheap deals, usually via spam email. A host of malicious websites have been set up mimicking official travel companies and accommodation providers to fool the unwary into disclosing their credit card details. Retail brands are also being spoofed, with offers sent via email for cut price replica shirts and various other World Cup apparel.
These World Cup 2018 phishing scams can usually be identified from the domain name, which needs to be checked carefully. These websites are often clones and are otherwise indistinguishable from the official websites.
Team and Match News and World Cup Gossip
As the World Cup gets underway, there are likely to be waves of spam emails sent with news about matches, team information, betting odds, and juicy gossip about teams and players. Every major sporting event sees a variety of lures sent via spam email to get users to click links and visit malicious websites. Hyperlinks often direct users to webpages containing fake login pages – Facebook and Google etc. – where credentials need to be entered before content is displayed.
How to Avoid Becoming a Victim of a World Cup 2018 Phishing Scam
These are just a few of the World Cup 2018 phishing scams that have been detected so far and a great deal more can be expected by the time the World Cup winner lifts the trophy on July 15.
Standard security best practices will help soccer fans avoid World Cup 2018 phishing scams. Make sure you:
Only buy tickets from the official FIFA website
Only book travel and accommodation from trusted vendors and review the vendors online before making a purchase
Never buy products or services advertised in spam email
Never opening attachments in World Cup-themed emails from unknown senders
Do not click hyperlinks in emails from unknown senders
Never click a hyperlink until you have checked the true domain and avoid clicking on shortened URLs
Ensure all software, including browsers and plugins, is patched and kept fully up to date
Ensure anti-virus software is installed and is kept up to date
Consider implementing a third-party spam filtering solution to prevent spam and malicious messages from being delivered – Something especially important for businesses to stop employees from being duped into installing malware on work computers.
Stay alert – If an offer seems to good to be true, it most likely is
The UK Government’s Department for Digital, Culture, Media, & Sport has published its Cybersecurity Breaches Survey for 2018. The survey, conducted by Ipsos MORI, was a quantitative and qualitative survey conducted in the winter of 2017 on 1,519 UK businesses and 569 UK registered charities.
The purpose of the cybersecurity breaches survey was to identify the nature and significance of cyberthreats, determine how prevalent cyberattacks are, and what is being done to prevent such attacks.
The cybersecurity breaches survey revealed UK businesses and charities are being targeted by cybercriminals intent on gaining access to sensitive information, email accounts, corporate networks, and bank accounts and attacks are on the rise.
43% of businesses and 19% of charities experienced a cybersecurity breach or cyberattack in the past 12 months with large businesses and charities more likely to be attacked. 72% of large businesses – those with more than 250 employees – and 73% of large charities – with incomes over £5 million – experienced a cyberattack in the past year.
While not all security breaches result in material losses such as theft of data or personal information, when there is a material outcome the costs can be significant. The average costs of breaches with a material outcome is £3,100 for businesses and £1,030 for charities, although the larger the business, the greater the cost. Medium sized businesses have average costs of £16,100 and large businesses have an average breach cost of £22,300.
The high probability of a breach occurring and the high cost of remediating breaches has seen cybersecurity become a priority for senior managers. The percentage of businesses (74%) and charities (53%) that say cybersecurity is a high priority has risen year on year and the percentage of businesses (30%) and charities (24%) that say cybersecurity is a low priority has fallen once again. Cybersecurity is also now a high priority for many small businesses (42%) having risen from 33% last year when the survey was conducted. Cybersecurity may be a high priority, but just 3 out of 10 businesses and under a quarter of charities have board members with a responsibility for cybersecurity.
The most common type of breaches and cyberattacks involve fraudulent emails directing employees to malicious websites. 75% of UK businesses and 74% of UK charities that experienced a breach in the past year experienced these types of attacks. Email impersonation attacks were the second most common breach type with 28% of UK businesses and 27% of UK charities saying they had experienced these types of incidents in the past 12 months.
Not only are these types of attacks common, they also cause the most disruption. 48% of UK businesses and charities said fraudulent emails and being directed to malicious websites caused the most disruption out of all cybersecurity breaches experienced, well ahead of malware infections which were rated as the most disruptive cyberattacks by 13% of UK businesses and 12% of UK charities.
The cybersecurity breaches survey clearly highlights the importance of implementing robust defenses to prevent malicious emails from being delivered to employees’ inboxes and to ensure staff are well trained and taught how to identify malicious emails.
TitanHQ offers two cybersecurity solutions that can help UK businesses block the most common and most disruptive types of cyberattack. SpamTitan is a powerful spam filtering solution that blocks more than 99.97% of spam emails and 100% of known malware from being delivered to end users’ inboxes.
WebTitan is a cloud-based web filtering solution that prevents employees from visiting malicious websites, such as those used in phishing emails to steal credentials and spread malware. Implementing these solutions is far cheaper than having to cover the cost of remediating cyberattacks.
There is also clearly a problem with training in the UK. Only 20% of UK businesses and 15% of UK charities have had staff attend internal or external cybersecurity training in the past year, even though security awareness training has clearly been shown to be effective at reducing susceptibility to email-based attacks.
According to data from the UK’s fraud tracking team, Action Fraud, there has been a massive rise in TSB phishing scams in the past few weeks. Customers of TSB have been duped into handing over their online banking credentials to scammers. Action Fraud is now receiving around 10 complaints a day from TSB customers who have fallen for phishing scams.
A Nightmare Scenario for TSB Customers
The problem that made the scams possible was the separation of the TSB banking system from Lloyds Bank, of which TSB was part until 2015. TSB moved over to a new core banking system provided by Banco Sabadell, the Spanish bank which took over TSB. That transition happened in April. Unfortunately for TSB and its customers, it did not go smoothly.
While migrating customer information to the new core banking system, many customers were locked out of their accounts and were unable to access their money. Some customers were presented with other customers’ bank accounts when they logged in online, and there have been cases of customers having money taken from their accounts without authorization, and transfers have been made to the wrong bank accounts. It is almost June, and the problems have still not been completely resolved.
Customers starting to experience problems over the weekend of 21/22 April and the problems were understandably covered extensively by the media with many customers taking to Social Media sites to vent their spleens over the chaos. For scammers, this was too good an opportunity to miss.
Action Fraud had received more than 320 reports of TSB phishing scams in the first three weeks in May. There were only 30 reports of such scams in the entire month of April. That’s an increase of 969%.
TSB Phishing Scams Soar
The situation was ideal for scammers. Many TSB customers could not access their accounts, so there was little chance of customers realizing they had been defrauded until it was too late.
TSB staff were overworked dealing with the IT problems and its helplines were overwhelmed with calls from customers unable to access their money. When customers realized they had been scammed they were unable to contact the bank quickly. There have been reports of customers seeing money taken from their accounts while they were logged in, yet they could not get through to customer support to stop transfers being made.
The TSB phishing scams used a combination of SMS messages, emails, and telephone calls to obtain customers banking credentials. As is typical in these types of scams, customers were sent links and were asked to use them to login to their accounts. The websites the bank’s customers visited looked exactly how they should. The only sign that the website was not genuine was the URL, otherwise the website was a carbon copy of the genuine TSB website.
Many victims of the scam had received an email or text messages, which was followed up with a voice call to obtain the 2-factor authentication code that would allow the scammers to gain access to the victim’s account. While the requests from the scammers may have seemed unusual or suspicious, this was an unusual situation for TSB customers.After that information was obtained, the scammers went to work and emptied bank accounts.
According to data from cybersecurity firm Wandera, TSB has now jumped to second spot in the list of the financial brands most commonly used in impersonation attacks. Prior to the IT problems, TSB wasn’t even in the top five.
With the bank’s IT issues ongoing, the TSB phishing scams are likely to continue at high levels for some time to come. The advice to TSB customers is to be extremely wary of any email, text message or call received from TSB bank. Scammers can spoof email addresses and phone numbers and can make text messages appear as if they have been sent by someone else.
Data breach costs have risen considerably in the past year, according to a recent study of corporate IT security risks by Kaspersky Lab. Compared to 2016, the cost of a data breach for enterprises increased by 24% in 2017, and by even more for SMBs, who saw data breach costs rise by 36% in 2017.
The average cost of data breach recovery for an average-sized enterprise is now $1.23 million per data breach, while the cost for SMBs is now $120,000 per incident.
For the study, Kaspersky Lab surveyed 6,614 business decision makers. Respondents were asked about the main threats they have to deal with, cybersecurity incidents they have experienced in the past year, how much they spent resolving those incidents, and how that money was spent.
When a data breach is experienced, the costs can quickly mount. Enterprises and SMBs must contain the attack, scan systems for malware and backdoors, and pay for improvements to security and infrastructure to prevent similar attacks from occurring in the future. Staff need to receive additional training, new staff often need to be brought in, and third-parties hired to assist with recovery and security assessments.
Data breach recovery can take time and considerable effort. Additional wages have to be paid to staff assisting in the recovery process, there can be losses due to system downtime, repairing damage to a brand prove costly, credit monitoring and identity theft recovery services may have to be provided to breach victims, insurance premiums rise, credit ratings drop, and there may also be regulatory fines to cover.
The largest component of data breach costs is making emergency improvements to security and infrastructure to prevent further attacks, which is around $193,000 per breach for enterprises, the second biggest cost for enterprises is repairing reputation damage, which causes major increases in insurance costs and can severely damage credit ratings. On average, this costs enterprises $180,000. Providing after-the-event security awareness training to the workforce was the third biggest cost for enterprises at $137,000.
It is a similar story for SMBs who typically pay around $15,000 for each of the above three cost categories. A lack of inhouse expertise means SMBs often have to call in cybersecurity experts to assist with making improvements to security and for forensic analyses to determine how access to data was gained.
Data breaches affecting third-party hosted infrastructure are the costliest for SMBs, followed by attacks on non-computing connected devices, third party cloud services, and targeted attacks. For enterprises, the costliest data breaches are targeted attacks followed by attacks on third-party infrastructure, attacks on non-computing connected devices, third party cloud services, and leaks from internal systems.
The high cost of recovering from a data breach means a successful cyberattack on an SMB could be catastrophic, forcing the company to permanently shut its doors. It is therefore no surprise that businesses are allocating more of their IT budgets to improving their security defenses. Enterprises are now spending an average of $8.9 million on cybersecurity each year, while SMBs spend an average of $246,000. Even though the cost of additional cybersecurity defenses is high, it is still far lower than the cost of recovering from data breaches.
While data breach prevention is a key driver for greater investment in cybersecurity, that is far from the only reason for devoting a higher percentage of IT budgets to security. The main drivers for increasing security spending are the increasing complexity of IT infrastructure (34%), improving the level of security expertise (34%), and management wanting to improve security defenses (29%).
A suspected nation-state sponsored hacking group has succeeded in infecting at least half a million routers with VPNFilter malware.
VPNFilter is a modular malware capable of various functions, including the monitoring of all communications, launching attacks on other devices, theft of credentials and data, and even destroying the router on which the malware has been installed. While most IoT malware infections – including those used to build large botnets for DDoS attacks – are not capable of surviving a reboot, VPNFilter malware can survive such a reset.
The malware can be installed on the type of routers often used by small businesses and consumers such as those manufactured by Netgear, Linksys, TP-Link and MikroTik, as well as network-attached storage (NAS) devices from QNAP, according to security researchers at Cisco Talos who have been monitoring infections over the past few months.
The ultimate aim of the attackers is unknown, although the infected devices could potentially be used for a wide range of malicious activities, including major cyberattacks on critical infrastructure, such as disrupting power grids – as was the case with BlackEnergy malware.
Since it is possible for the malware to disable Internet access, the threat actors behind the campaign could easily prevent large numbers of individuals in a targeted region from going online.
While the malware has been installed on routers around the world – infections have been detected in 54 countries – the majority of infections are in Ukraine. Infections in Ukraine have increased significantly in the past few weeks.
While the investigation into the campaign is ongoing, the decision was taken to go public due to a massive increase in infected devices over the past three weeks, together with the incorporation of advanced capabilities which have made the malware a much more significant threat.
While the researchers have not pointed the finger at Russia, they have identified parts of the code which are identical to that used in BlackEnergy malware, which was used in several attacks in Ukraine. BlackEnergy has been linked to Russia by some security researchers. BlackEnergy malware has been used by other threat actors not believed to be tied to Russia to the presence of the same code in both forms of malware is not concrete proof of any link to Russia.
The FBI has gone a step further by attributing the malware campaign to the hacking group Fancy Bear (APT28/Pawn Storm) which has links to the Russian military intelligence agency GRU. Regardless of any nation-state backing, the sophisticated nature of the malware means it is the work of a particularly advanced hacking group.
Most of the attacked routers are aging devices that have not received firmware updates to correct known flaws and many of the attacked devices have not had default passwords changed, leaving them vulnerable to attack. It is not entirely clear exactly how devices are being infected although the exploitation of known vulnerabilities is most probable, rather than the use of zero-day exploits; however, the latter has not been ruled out.
Some progress has been made disrupting the VPNFilter malware campaign. The FBI has seized and sinkholed a domain used by the malware to communicate with the threat group behind the campaign. Without that domain, the attackers cannot control the infected routers and neither identify new devices that have been infected.
Ensuring a router is updated and has the latest firmware will offer some degree of protection, as will changing default passwords on vulnerable devices. Unfortunately, it is not easy to tell if a vulnerable router has been infected. Performing a factory reset of a vulnerable router is strongly recommended as a precaution.
Rebooting the device will not eradicate the malware, but it will succeed in removing some of the additional code downloaded to the device. However, those additional malware components could be reinstalled once contact is re-established with the device.
Several GDPR phishing scams have been detected in the past few days as scammers capitalize on the last-minute rush by companies to ensure compliance ahead of the May 25, 2018 GDPR deadline. Be wary about any GDPR related email requests – they may be a scam.
GDPR Provides Scammers with a New Opportunity
You will probably already be sick of receiving email requests from companies asking if they can continue sending you emails, but that is one of the requirements of GDPR. GDPR requires consent to be obtained to use – or continue to use – personal information. With previous privacy policies failing to comply with the new EU law, email requests are being sent to all individuals on mailing lists and those who have previously registered on websites to re-obtain consent.
All companies that have dealings with EU residents are required to comply with GDPR, regardless of their location. Emails are therefore being sent from companies far and wide. Consumers are receiving messages from companies that they may have forgotten they had dealings with in the past. If personal data is still on file, email requests are likely to be sent asking for permission to retain that information.
The masses of emails now being sent relating to GDPR has created an opportunity for scammers. GDPR phishing scams have been developed to fool users into revealing sensitive information under the guise of GDPR related requests. There have been many GDPR phishing scams identified in recent weeks. It is ironic that a regulation that aims to improve privacy protections for EU residents is being used to violate privacy.
Apple Spoofed in New Phishing Scam
Phishers often spoof large, familiar brands as there is a greater chance that the recipient of the message will have an account with that company. The most popular global brands – Netflix, PayPal, Apple, and Google are all commonly impersonated.
These impersonation scams can be highly convincing. A request is sent via email that seems perfectly reasonable, the emails appear to have been sent from the company, and the email address of the sender is spoofed to appear genuine. The emails contain branding and images which are familiar, and the messages can be almost indistinguishable from genuine communications.
The aim is to get users to click on an embedded hyperlink and visit the company’s website and login. There is usually an urgent call to action, such as a security alert, threat of account closure, or loss of services.
Apple is one such brand that has recently been impersonated in GDPR phishing scams. The aim of the attackers is to get Apple customers to login to a fake site and disclose their credentials. Once the credentials have been obtained, the scammers have access the user’s account, which includes financial information, credit card details, and other personal information.
Airbnb GDPR Phishing Scams Detected
Redscan has detected Airbnb GDPR phishing scams recently. Users of its home sharing platform are required to update their contact details due to GDPR law in order to continue to use the platform. The request is entirely reasonable given so many companies are sending similar emails.
The emails claim to be from Airbnb customer service, contain the correct images and branding, and direct users to a familiar looking website that differs only in the domain name. Users are asked to re-enter their contact information and payment card details.
Watch Out for GDPR Phishing Scams
These scams are just two of several. More can be expected over the coming days in the run up to the compliance deadline and beyond. To avoid falling for the scams, make sure you treat all GDPR-related requests as potentially suspicious.
The easiest way to avoid the scams is to visit the website of the brand by typing the correct address directly into the browser or using your usual bookmark. It should be clear when you login if you need to update your information because of GDPR.
Ransomware attacks on businesses appear to be declining. In 2017 and 2018 there has been a marked decrease in the number of attacks. While this is certainly good news, it is currently unclear whether the fall in attacks is just a temporary blip or if the trend will continue.
Ransomware attacks may have declined, but there has been a rise in the use of cryptocurrency mining malware, with cybercriminals taking advantage in the high price of cryptocurrencies to hijack computers and turn them into cryptocurrency-mining slaves. These attacks are not as devastating or costly as ransomware attacks, although they can still take their toll, slowing down endpoints which naturally has an impact on productivity.
While ransomware attacks are now occurring at a fraction of the level of 2016 – SonicWall’s figures suggest there were 184 million attacks in 2017 compared to 638 million in 2016 – the risk of an attack is still significant.
Small players are still taking advantage of ransomware-as-a-service – available through darknet forums and marketplaces – to conduct attacks and organized cybercriminal gangs are conducting targeted attacks. In the case of the latter, victims are being selected based on their ability to pay and the likelihood of a payment being made.
These targeted attacks have primarily been conducted on organizations in the healthcare industry, educational institutions, municipalities and the government. Municipalities are targeted because massive disruption can be caused, and attacks are relatively easy to pull off. Municipalities typically do not have the budgets to devote to cybersecurity.
Attacks in healthcare and education industries are made easier by the continued use of legacy software and operating systems and highly complex networks that are difficult to secure. Add to that the reliance on access to data and not only are attacks relatively easy, there is a higher than average chance of a ransom being paid.
In the past, the aim of ransomware gangs was to infect as many users as possible. Now, targeted attacks are conducted with the aim of infecting as many end points as possible within an organization. The more systems and computers that are taken out of action, the greater the disruption and cost of mitigating the attack without paying the ransom.
Most organizations, government agencies, municipalities, have sound backup policies and can recover all data encrypted by ransomware without paying the ransom. However, the time taken to recover files from backups and restore systems – and the cost of doing so – makes payment of the ransom preferable.
The attack on the City of Atlanta shows just how expensive recovery can be. The cost of restoring systems and mitigating the attack was at least $2.6 million – The ransom demand was in the region of $50,000. It is therefore no surprise that so many victims have chosen to pay up.
Even though the ransom payment is relatively low compared to the cost of recovery, it is still far more expensive than the cost of implementing security solutions to prevent attacks.
There is no single solution that can block ransomware and malware attacks. Multi-layered defenses must be installed to protect the entire attack surface. Most organizations have implemented anti-spam solutions to reduce the risk of email-based attacks, and security awareness training is helping to eliminate risky behaviors and teach security best practices, but vulnerabilities still remain with DNS security often lacking.
Vulnerabilities in DNS are being abused to install ransomware and other malware variants and hide communications with command and control servers and call home addresses. Implementing a DNS-based web filtering solution offers protection against phishing, ransomware and malware by preventing users from visiting malicious websites where malware and ransomware is downloaded and blocking C2 server communications. DNS-based web filters also provide protection against the growing threat from cryptocurrency mining malware.
To mount an effective defense against phishing, malware and ransomware attacks, traditional cybersecurity defenses such as ant-virus software, spam filters, and firewalls should be augmented with web filtering to provide security at the DNS layer. To find out more about how DNS layer security can improve your security posture, contact TitanHQ today and ask about WebTitan.
Another school district has fallen victim to a ransomware attack, which has seen files encrypted and systems taken out of action for two weeks. The Leominster school district ransomware attack saw a ransom demand of approximately $10,000 in Bitcoin was issued for the keys to unlock the encrypted files, which includes the school’s entire student database.
School districts attacked with ransomware often face a difficult decision when ransomware is installed. Attempt to restore systems and recover lost data from backups or pay the ransom demand. The first option is time consuming, costly, and can see systems remain out of action for several days. The second option includes no guarantees that the attackers will make good on their promise and will supply valid keys to unlock the encryption. The keys may not be held, it may not be possible to unlock files, or a further ransom demand could be issued. There have been many examples of all three of those scenarios.
The decision not to pay the ransom demand may be the costlier option. The recent ransomware attack on the City of Atlanta saw a ransom demand issued in the region of $50,000. The cost of recovering from the attack was $2.6 million, although that figure does include the cost of improvements to its security systems to prevent further attacks.
School districts are often targeted by cybercriminals and ransomware offers a quick and easy way to make money. The attackers know all too well that data can most likely be recovered from backups and that the ransom does not need to be paid, but the cost of recovery is considerable. Ransom demands are set accordingly – high enough for the attackers to make a worthwhile amount, but low enough to tempt the victims into paying.
In the case of the Leominster ransomware attack, the second option was chosen and the ransom demand of was paid. That decision was taken after carefully weighing up both options. The risk that no keys would be supplied was accepted. In this case, they were supplied, and efforts are well underway to restore files and implement further protections to ensure similar incidents do not occur in the future.
Even though the ransom was paid, the school district was still without access to its database and some of its computer systems two weeks after the attack. Files were encrypted on April 14, but systems were not brought back online until May 1.
Unfortunately for the Leominster School District, ransom payments are not covered by its cyberinsurance policy, so the payment had to come from its general fund.
There is no simple way to defend against ransomware attacks, as no single cybersecurity solution will prove to be 100% effective at blocking the threat. Multiple attack vectors are used, and it is up to school districts to implement defenses to protect the entire attack surface. The solution is to defend in numbers – use multiple security solutions to create layered defenses.
Some of the most important defenses include:
An advanced firewall to defend the network perimeter
Antivirus and anti-malware solutions on all endpoints/servers
Vulnerability scanning and good patch management policies. All software, systems, websites, applications, and operating systems should be kept up to date with patches applied promptly
An advanced spam filtering solution to prevent malicious emails from being delivered to end users. The solution should block all executable files
Disable RDP if it is not required
Provide security awareness training for employees and teach staff and students the skills to enable them to identify malicious emails and stop risky behaviors
A web filtering solution capable of blocking access to malicious websites
The cost of implementing these solutions is likely to be far lower than the cost of a ransom payment and certainly lower than the cost of mitigating a ransomware attack.
The cost of the Equifax data breach has risen to more than $242 million, and that figure will continue to rise and could even double.
According to the Equifax financial report for the first quarter of 2018, the total spent on mitigation and preventative measures to avoid a further security breach is now $242.7 million.
The breach, which was made public in September 2017, affected 147.9 million customers, making it one of the largest data breaches ever discovered and certainly one of the most serious considering the types of data involved. Yahoo may have experienced much larger breaches, but the data exposed in those incidents was far less sensitive.
Fortunately for Equifax, it holds a sizable insurance policy against cybersecurity incidents. The policy will cover up to $125 million of the cost, minus a $7.5 million deductible. That insurance policy has already paid out $60 million, with $10 million in payments received in the first quarter of 2018.
The breakdown of cost of the Equifax data breach so far for Q1, 2018 is:
$45.7 million on IT security
$28.9 million on legal fees and investigation of the breach
$4.1 million on product liability
$10 million has been recovered from an insurance payout.
The net expenses from the breach in the first quarter of 2018 was $68.7 million. That is on top of the $114 million spent in the final quarter of 2017, which is broken down as $64.6 million on product costs and customer support, $99.4 million on professional fees, minus $50 million that was paid by its insurance carrier. The net spend so far for Q4, 2017 and Q1, 2018 is $140.5 million, although Equifax reports that the total costs related to the cybersecurity incident and incremental IT and data security costs has been $242.7 million.
Equifax has also reported that throughout 2018 and 2019 the firm will be investing heavily in IT and is committed to building an industry-leading data security system, although the firm has not disclosed how much it is expecting to spend, as the company does not have visibility into costs past 2018.
Equifax has predicted that there will be at least a further $275 million in expenses related to the cyberattack which must still be covered, although a further $57.5 million should be covered by its insurance policy.
While considerable costs have been incurred so far, the firm has done little to repair the reputational damage suffered as a result of the breach and has yet to hire many of the new staff it plans to bring in to help with the breach recovery, including a new CTO. The firm has said that it is taking a very aggressive approach in attracting the top talent in both IT and data security.
The high cost of the Equifax data breach to date, and the ongoing costs, is likely to make this the most expensive data breach of all time.
The Atlanta ransomware attack that took IT systems and computers out of action and brought many municipal operations to a grinding halt has proven particularly costly for the city.
On March 22, 2018, ransomware was deployed on its network forcing a shutdown of PCs and systems used by some 8,000 employees. Those employees were forced to work on pen and paper while attempts were made to recover from the attack. With IT systems offline, many municipal services stopped entirely.
The attackers sent a ransom demand for approximately $50,000. By paying the ransom, the city could potentially have been given the keys to unlock the files encrypted by the SamSam ransomware variant used in the attack. However, there are never any guarantees decryption keys will be supplied. Many victims have received further demands for payment after the initial demand was paid, and there have been many cases where the attackers have not made good on their promise and did not supply any valid keys.
It is unclear whether the ransom payment was made, although that appears unlikely. The payment portal used by the attackers went offline shortly after the attack and the cleanup costs following the Atlanta ransomware attack have been considerable. The high cost suggests the city opted to recover its data and restore systems from backups.
In the immediate aftermath of the Atlanta ransomware attack, the city awarded emergency procurements to eight firms to assist with recovery efforts. The total cost of those services was $2,667,328.
The city spent $60,000 on incident response services, $50,000 on crisis communication services, and $60,000 on support staff augmentation. Secureworks was paid $650,000 for emergency incident response services, Two contracts were awarded to assist with its Microsoft cloud and Windows environments, including migrating certain on-premises systems to the cloud. Those two contracts totaled $1,330,000 and a further $600,000 was paid to Ernst & Young for advisory services for cyber incident response. The $2.6 million cost could rise further still.
Paying the threat actors who conducted the Atlanta ransomware attack could well have seen sizable savings made, although it would certainly not have cost $50,000. Some of the costs associated with recovery from the attack have been spent on improving security to prevent further incidents, and certainly to make recovery less costly. Those costs would still have to be recovered even if the ransom was paid.
What is clear however, is that $2.6 million paid on reactive services following a ransomware attack will not give tremendous value for money. Had that amount been spent on preventative measures prior to the attack, the city would have got substantially more value for every buck spent. Some industry experts have estimated the cost of preventative measures rather than reactive measures would have been just 20% of the price that was paid.
The attack revealed the City of Atlanta was unprepared and had failed to implement appropriate defenses. The city was vulnerable to attack due to the failure to apply security best practices, such as closing open ports on its systems and segmenting its network. The vulnerabilities made an attack far to easy. However, it would be unfair to single out the city as many others are in exactly the same position.
This incident should therefore serve as a stern warning to other cities and organizations that the failure to adequately prepare for an attack, implement appropriate defenses, and apply security best practices will likely lead to an incredibly costly attack.
It may be difficult to find the money to spend on ransomware attack prevention measures, but it will be much harder to find five times the cost to implement defenses and respond after an attack has taken place.
A warning has been issued to the healthcare industry over an extensive campaign of targeted cyberattacks by the Orangeworm threat group. The Orangeworm threat group has been operating since 2015, but activity has been largely under the radar. It is only recently that the group’s activities have been identified and disclosed.
Attacks have been conducted on a range of industries, although the primary targets appear to be large healthcare organizations. 39% of confirmed attacks by the Orangeworm threat group have been on organizations in the healthcare industry, including large healthcare providers and pharmaceutical firms. IT service providers, manufacturers, and logistics firms have also been attacked, many of which have links to the healthcare industry.
Some of the IT service providers discovered to have been attacked have contracts with healthcare organizations, while logistics firms have been attacked that deliver medical equipment, as have manufacturers of medical devices. The aim appears to be to infect and investigate the infrastructure of the entire supply chain.
The Orangeworm threat group is using a custom backdoor, which is deployed once access to a network is gained. First the backdoor is deployed on one device, giving the Orangeworm threat group full control of that device. The backdoor is then aggressively spread laterally within a network via unprotected network shares to infect as many devices as possible with the Kwampirs backdoor. While some steps have been taken by the group to avoid detection, this lateral worm-like movement is noisy and easily detected. The threat group does not seem to be overly concerned about hiding its activity.
This attack method works best on legacy operating systems such as Windows XP. Windows XP is no longer supported, and even though the continued use of the operating system is risky and in breach of industry regulations, many healthcare organizations still have many devices operating on Windows XP, especially machines connected to imaging equipment such as MRI and X-Ray machines. It is these machines that have been discovered to have been infected with the Kwampirs backdoor.
Once access is gained, the group is spending a considerable amount of time exploring networks and collecting information. While the theft of patient health information is possible, this does not appear to be a financially motivated attack and systems are not sabotaged.
Symantec, which identified a signature which has allowed the identification of the backdoor and raised the alert about the Orangeworm threat group, believes this is a large-scale espionage campaign with the aim of learning as much as possible about the targets’ systems. What the ultimate goal of the threat group is, no one knows.
The method of spreading the backdoor does not have the hallmarks of nation-state sponsored attacks, which tend to use quieter methods of spreading malware to avoid detection. However, the attacks are anything but random. The companies that have been attacked appear to have been targeted and well researched before the attacks have taken place.
That suggests the Orangeworm threat group is a cybercriminal gang or small collective of hackers, but the group is clearly organized, committed to its goals, and is capable of developing quite sophisticated malware. However, even though the group is clearly capable, and has operated under the radar for three years, during that time no updates have been made to their backdoor. That suggests the group has been confident that they would not be detected, or that they simply didn’t see the need to make any updates when their campaign was working so well.
While espionage may be the ultimate aim, the Orangeworm threat group could easily turn to more malicious and damaging attacks. Once the backdoor has been installed on multiple devices, they would be under full control of the hackers. The group has the capability to deploy malware such as wipers and ransomware and cause considerable damage or financial harm.
The ease at which networks can be infiltrated and the backdoor spread should be of major concern for the healthcare industry. The attacks show just how vulnerable the industry is and how poorly protected many organizations are.
The continued use of outdated and unsupported operating systems, a lack of network segmentation to prevent lateral movement once access has been gained, the failure to protect network shares, and poor visibility of the entire network make these attacks far too easy. In fact, simply following security best practices will prevent such attacks.
The attacks by the Orangeworm threat group should serve as a wakeup call to the industry. The next wave of attacks could be far, far worse.
Microsoft has released new figures that show there has been a sizeable increase in tech support scams over the past year. The number of victims that have reported these scams to Microsoft increased by 24% in 2017. The true increase could be much higher. Many victims fail to report the incidents.
According to Microsoft, in 2017 there were 153,000 reports submitted from customers in 183 countries who had been fooled by such a scam. While not all of the complainants admitted to losing money as a result, 15% said they paid for technical support. The average cost of support was between $200 and $400, although many individuals were scammed out of much more significant amounts. While victims may not willingly pay much more to fix the fictitious problem on their computers, if bank account details are provided to the scammers, accounts can easily be drained. One victim from the Netherlands claims a scammer emptied a bank account and stole €89,000.
The rise in complaints about tech support scams could, in part, be explained by more scammers pretending to be software engineers from Microsoft, prompting them to report the incidents to Microsoft when they realize they have been scammed.
However, the rise in tech support scams is backed up by figures released by the FBI. Its Internet Crime Complaint Center (IC3) received 86% more complaints in 2017 from victims of tech support scams. Around 11,000 complaints were received by IC3 about tech support scams last year and more than $15 million was lost to the scams.
It is easy to see why these scams are so attractive for would-be cybercriminals. In many cases, little effort is required to pull off the scam. All that is required in many cases is a telephone. Cold calling is still common, although many of the scams are now much more sophisticated and have a much higher success rate.
Email is also used. Some tech support scams involve warnings and use social engineering techniques to convince the recipient to call the helpline. Others involve malware, sent as an attachment or downloaded as a result of visiting a malicious website via a hyperlink supplied in the email.
Once installed, the malware displays fake warning messages that convince the user that they have been infected with malware that requires a call to the technical support department.
The use of popups on websites is common. These popups cannot be closed and remain on screen. Browser lockers are also common which serve the same purpose. To prompt the user to call the support helpline.
While many more experienced users would know how to close the browser – CTRL+ALT+DEL and shut down the browser via Windows Task Manager – less experienced users may panic and call the helpline number, especially when the popup claims to be from a well-known company such as Microsoft or even law enforcement.
The typical process used in these tech support scams is to establish contact by telephone, get the user to download software to remove a fictitious virus or malware that has previously been installed by the attackers. Remote administration tools are used that allows the scammer to access the computer. The user is convinced there is malware installed and told they must pay for support. Payment is made and the fictitious problem is fixed.
These techniques are nothing new, it is just that more cybercriminals have got in on the act and operations have been expanded due to the high success rate. Fortunately, there are simple steps to take that can prevent users from falling for these tech support scams.
To avoid becoming a victim of such a scam:
Never open any email attachments you receive from unknown senders
Do not visit hyperlinks in email messages from unknown senders
If contacted by phone, take a number and say you will call back. Then contact the service provider using verified contact information, not the details supplied over the telephone
If you are presented with a warning via a popup message or website claiming your device has been infected, stop and think before acting. Genuine warnings do not include telephone numbers and do not have spelling mistakes or questionable grammar
If you receive a warning about viruses online and want to perform a scan, download free antivirus software from a reputable firm from the official website (Malwarebytes, AVG, Avast for instance)
Before making any call, verify the phone number. Use a search engine to search for the number and see if it has been associated with scams in the past
ISPs and service providers rarely make unsolicited telephone calls to customers about viruses and technical issues and offer to fix the device
If you believe you are a victim of a tech support scam, report the incident to the service provider who was spoofed and notify appropriate authorities in your country of residence.
In the USA, that is the Federal Trade Commission or the FBI’s IC3; in the UK it is the National Fraud and Cyber Crime Reporting Center, the European Consumer Center in Ireland, or the equivalent organizations in other countries.
Two new phishing campaigns have been detected in the past few days that have seen phishers sink to new lows. An active shooter phishing campaign has been detected that uses fear and urgency to steal credentials, while a Syrian refugee phishing campaign takes advantage of compassion to increase the probability of victims paying ransom demands.
Active Shooter Phishing Campaign
Mass shootings at U.S schools are on the rise, with the latest incident in Parkland, Florida placing teachers and other staff on high alert to the threat of campus shootings. A rapid response is essential when an active shooter alert is issued. Law enforcement must be notified quickly to apprehend the suspect and children and staff must be protected.
It is therefore no surprise that fake active shooter threats have been used in a phishing campaign. The emails are designed to get email recipients to click without thinking to receive further information on the threat and have been developed to cause fear and panic.
The active shooter phishing campaign was being used in a targeted attack on a Florida school – an area of the country where teachers are hypersensitive to the threat of shootings, given recent events in the state.
Three active shooter phishing email variants were reported to the anti-phishing and security awareness platform provider KnowBe4, all of which were used to direct recipients to a fake Microsoft login page where they were required to enter in their login credentials to view the alert. Doing so would give those credentials to the attacker.
The email subject lines used – although other variants could also be in use – were:
IT DESK: Security Alert Reported on Campus
IT DESK: Campus Emergency Scare
IT DESK: Security Concern on Campus Earlier
It is likely that similar campaigns will be conducted in the future. Regardless of the level of urgency, the same rules apply. Stop and think about any message before taking any action suggested in the email.
Syrian Refugee Phishing Campaign
Phishing campaigns often use crises, major world events, and news of sports tournaments to get users to click links or open email attachments. Any news that is current and attracting a lot of interest is more likely to result in users taking the desired action.
There have been several Syrian refugee phishing campaigns run in recent months that take advantage of compassion to infect users with malware and steal their credentials. Now researchers at MalwareHunterTeam have identified a ransomware campaign that is using the terrible situation in Syria to convince victims to pay the ransom – By indicating the ransom payments will go to a very good cause: Helping refugees.
Infection with what has been called RansSIRIA ransomware will see the victim presented with a ransom note that claims all ransom payments will be directed to the victims of the war in Syria. A link is also provided to a video showing the seriousness of the situation in Syria and links to a WorldVision document explaining the plight of children affected by the war.
While the document and images are genuine, the claim of the attackers is likely not. There is no indication that any of the ransom payments will be directed to the victims of the war. If infected, the advice is not to pay and to try to recover files by other means. If you want to do your bit to help the victims of the war, make a donation to a registered charity that is assisting in the region.
What is the future of the system administrator? What can sysadmins expect over the coming months and years and how are their jobs likely to change? Our predictions on what is likely to happen to the role in the foreseeable future.
What Does the Future of the System Administrator Have in Store?
The system administrator is an important role in any organization. Without sysadmins to deal with the day to day IT problems faced by organizations, the business would grind to a halt. Sysadmins also play an essential role in ensuring the security of the network by taking proactive steps to keep systems secure as well as responding to threats before they result in a data breach. With more cyberattacks occurring, increasingly complex IT systems being installed, and the fast pace of technological development, one thing is for sure: The future of the system administrator is likely to continue to involve long hours and hard work.
It is also easy to predict that the future of the system administrator will involve major changes to job descriptions. That has always been the case and never more so than now. There will be a continued need for on the job training and new systems and processes must continue to be learned. Being a System administrator is therefore unlikely to be boring.
According to data from the US Bureau of Labor Statistics, there is likely to be sustained growth in the profession for the next two years. While the forecast was previously 12% growth, this has now been reduced to 6% – similar to other occupations. The increased automation of many sysadmin tasks is partly responsible for this decline in growth, since businesses are likely to need less staff as manual processes are reduced. That said, the figures indicate demand for IT workers will remain high. Even with newer, faster technology being implemented, staff are still required to keep everything running smoothly.
XaaS, the Cloud, Virtualization, and VoIP Use to Grow
Unfortunately, while automation means greater efficiency, it can entail many hidden costs. For a start, with more automation it can become harder to determine the source of a problem when something goes wrong. Increased automation also means the system administrator must become even more knowledgeable. Automation typically involves scripting in various languages, so while you may have been able to get away with knowing Python or Windows PowerShell, you will probably need to become proficient in both, and maybe more.
If you are considering becoming a system administrator, now is the time to learn your first scripting language, as it will make it easier to learn others on the job if you understand the basics. It will also help you to get the job in the first place. The more you know, the better.
Use of the cloud is increasing, especially for backup and archiving, which in turn has reduced the need for server-centered tasks. While there has been a reduction in labor-intensive routine data operations, there has been a rise in the need to become proficient in the use of Application Programming Interfaces (APIs).
While many functions are now being outsourced through XaaS, it is still important to understand those functions. The future of the system administrator is likely to require XaaS to be screened and assessed to make sure those services match the IT needs of the organization. Sales staff will likely say their XaaS meets all business needs. Having an SA that understands the functions, the technology, and the needs of the business will be invaluable for screening out the services that are unsuitable.
To cut costs, many businesses are turning to VoIP. While this does offer considerable cost savings, businesses cannot tolerate less than the 99.999% of uptime offered by phone companies. The future of the system administrator is therefore likely to involve a thorough understanding of the dynamics of network load.
Virtualization has also increased, with a myriad of virtual networks making the SA’s job more complex. That means knowledge of switching and routing will have to improve.
Communication, Collaboration, and Negotiation Skills Required
The SA’s job no longer just involves studying manuals and learning new systems. SAs are now expected to be able to communicate more effectively, understand the business, and collaborate with others. SAs will need strong communication skills, must become excellent collaborators, and also be skilled at negotiation. Fortunately, there are many courses available that can help SAs improve in these areas.
Providing security awareness training for employees helps to eradicate risky behaviors that could potentially lead to a network compromise. Training programs should cover all the major threats faced by your organization, including web-based attacks, phishing emails, malware, and social engineering scams via the telephone, text message, or social media channels.
All too often, businesses concentrate on securing the network perimeter with firewalls, deploying advanced anti-malware solutions, and implementing other technological controls such as spam filters and endpoint protection systems, yet they fail to provide effective security awareness training for employees. Even when security awareness training programs are developed, they are often once-a-year classroom-based training sessions that are forgotten quickly.
If you view security awareness training for employees as a once-a-year checkbox item that needs to be completed to ensure compliance with industry regulations, chances are your training will not have been effective.
The threat landscape is changing rapidly. Cybercriminals often change their tactics and develop new methods to attack organizations. If your security program does not incorporate these new methods of attack, and you do not provider refresher security awareness training for employees throughout the year, your employees will be more likely to fall for a scam or engage in actions that threaten the security of your data and the integrity of your network.
Many Businesses Fail to Provide Effective Security Awareness Training for Employees
One recent study has highlighted just own ineffective many security awareness training programs are. Positive Technologies ran a phishing and social engineering study on ten organizations to determine how effective their security awareness programs were and how susceptible employees are to some of the most common email-based scams.
These include emails with potentially malicious attachments, emails with hyperlinks to websites where the employee was required to enter their login credentials, and emails with attachments and links to a website. While none of the emails were malicious in nature, they mirrored real-world attack scenarios.
27% of employees responded to the emails with a link that required them to enter their login credentials, 15% responded to emails with links and attachments, and 7% responded to emails with attachments.
Even a business with 100 employees could see multiple email accounts compromised by a single phishing campaign or have to deal with multiple ransomware downloads. The cost of mitigating real world attacks is considerable. Take the recent City of Atlanta ransomware attack as an example. Resolving the attack has cost the city $2.7 million, according to Channel 2 Action News.
The study revealed a lack of security awareness across each organization. While employees were the biggest threat to network security, accounting for 31% of all individuals who responded to the emails, 25% were team supervisors who would have elevated privileges. 19% were accountants, administrative workers, or finance department employees, whose computers and login credentials would be considerably more valuable to attackers. Department managers accounted for 13% of the responders.
Even the IT department was not immune. While there may not have been a lack of security awareness, 9% of responders were in IT and 3% were in information security.
The study highlights just how important it is not only to provide security awareness training for employees, but to test the effectiveness of training and ensure training is continuous, not just a once a year session to ensure compliance.
Tips for Developing Effective Employee Security Awareness Training Programs
Employee security awareness training programs can reduce susceptibility to phishing attacks and other email and web-based threats. If you want to improve your security posture, consider the following when developing security awareness training for employees:
Create a benchmark against which the effectiveness of your training can be measured. Conduct phishing simulations and determine the overall level of susceptibility and which departments are most at risk
Offer a classroom-style training session once a year in which the importance of security awareness is explained and the threats that employees should be aware of are covered
Use computer-based training sessions throughout the year and ensure all employees complete the training session. Everyone with access to email or the network should receive general training, with job and department-specific training sessions provided to tackle specific threats
Training should be followed by further phishing and social engineering simulations to determine the effectiveness of training. A phishing simulation failure should be turned into a training opportunity. If employees continue to fail, re-evaluate the style of training provided
Use different training methods to help with knowledge retention
Keep security fresh in the mind with newsletters, posters, quizzes, and games
Implement a one-click reporting system that allows employees to report potentially suspicious emails to their security teams, who can quickly take action to remove all instances of the email from company inboxes
The SamSam ransomware attacks are continuing and the threat actors behind the campaign are showing no sign of stopping. So far in 2018 there have been at least 10 attacks in the United States, although many more may have gone unreported. Most of the known attacks have hit government agencies, municipalities, and healthcare organizations – all of whom are required to disclose attacks.
The attacks have caused massive disruption, taking computers, servers, and information systems out of action for several days to several weeks. Faced with the prospect of continued disruption to essential business processes, some organizations have chosen to pay the ransom – a risky strategy since there is no guarantee that the keys to unlock the encryption will work or even be supplied.
Others have refused to be extorted, often at great cost. One U.S. healthcare provider, Erie County Medical Center, took six weeks to fully recover from the attack. Mitigating the attack has cost several million dollars.
Multiple SamSam ransomware attacks are possible as the Colorado Department of Transportation discovered. After recovering from an attack in February, a second attack occurred in March.
It is not only financial harm that is caused by the attacks. Another hospital was attacked, and its outpatient clinic and three physician hospitals were unable to view histories or schedule appointments. The ransomware attack on the electronic medical record provider AllScripts saw its EMR systems taken out of action for several days. During that time, around 1,500 medical centers were unable to access patient health records resulting in many cancellations of non-critical medical appointments.
The March SamSam ransomware attack on the City of Atlanta brought many government services to a grinding halt. The extensive attack forced the shutdown of many systems, many of which remained inaccessible for six days. Bills and parking tickets couldn’t be paid and court proceedings had to be cancelled. The huge backlog of work continued to cause delays when systems were restored.
While the SamSam ransomware attacks have been concentrated on just a few industry sectors, the attacks are not necessarily targeted. What the victims have in common is they have been found to have easily exploitable vulnerabilities on public facing servers. They were attacked because mistakes had been made, vulnerabilities had not been patched promptly, and weak passwords had been set.
The threat actors behind the latest SamSam ransomware attacks have not been confirmed, although researchers at Secureworks believe the attacks are being conducted by the Gold LOWELL threat group. It is not known whether they are a defined group or a network of closely affiliated threat actors. What is known, whether it is GOLD LOWELL or other group, is they are largely staying under the radar.
What is more certain is the SamSam ransomware attacks will continue. In the first four weeks of January, the Bitcoin wallet used by the attackers showed $325,000 of ransom payments had been paid. The total in April is likely to be substantially higher. Hancock Health, one of two Indiana hospitals attacked this year, has confirmed that it paid a ransom demand of approximately $55,000 for the keys to unlock the encryption. As long as the attacks remain profitable and the threat actors can stay under the radar, there is no incentive to stop.
In contrast to many threat actors that use phishing emails and spam messages to deliver ransomware downloaders, this group exploits vulnerabilities on public-facing servers. Access is gained to the network, the attackers spend time navigating the network and moving laterally, before the ransomware payload is finally deployed. Detecting network intrusions quickly may prevent file encryption, or at least limit the damage caused.
The ongoing campaign has now prompted the U.S. Department of Health and Human Services’ Healthcare Cybersecurity Integration and Communications Center (HCCIC) to issue a warning to healthcare organizations about the continued threat of attacks. Healthcare organizations should heed the advice of the HCCIC and not only implement defences to block attacks but also to prepare for the worst. If contingency plans are made and incident response procedures are developed in advance, disruption and cost will be kept to a minimum.
That advice from the HCCIC to prevent SamSam ransomware attacks is:
Conduct vulnerability scans and risk assessments to identify potential vulnerabilities
Ensure those vulnerabilities are remediated
Ensure patches are applied promptly
Use strong usernames and passwords and two-factor authentication
Limit the number of users who can login to remote desktop solutions
Restrict access to RDP behind firewalls and use a VPN or RDP gateway
Use rate limiting to stop brute force attacks
Ensure backups are made for all data to allow recovery without paying the ransom and make sure those backups are secured
Develop a contingency plan to ensure that the business can continue to function while the attack is mitigated
Develop procedures that can easily be followed in the event of a ransomware attack
Implement defenses capable of detecting attacks quickly when they occur
Conduct annual penetration tests to identify vulnerabilities and ensure those vulnerabilities are rapidly addressed
Under Armour has experienced a massive MyFitnessPal data breach that has resulted in the personal information of 150 million users being accessed and stolen by a hacker.
The data relates to users of the mobile MyFitnessPal app and the web version of the fitness and health tracking platform. The types of data stolen in the MyFitnessPal data breach include hashed usernames, passwords and email addresses.
While payment card data is held by Under Armour, the information is processed and stored separately and was unaffected. Other highly sensitive information typically used for identity theft and fraud such as Social Security numbers was not obtained by the attacker.
The MyFitnessPal data breach is notable for the sheer volume of data obtained and is the largest data breach to be detected this year; however, the theft of hashed data would not normally pose an immediate risk to users. That is certainly the case for the passwords, which were hashed using bcrypt – a particularly strong hashing algorithm. However, usernames and passwords were only hashed using the SHA-1 hashing function, which does not offer the same level of protection. It is possible to decode SHA-1 hashed data, which means the information could potentially be accessed by the attacker.
Further, the attacker has had the data for some time. Under Armour became aware of the breach on March 25, 2018, but the attack took place more than a month before it was detected – some six weeks before the announcement about the data breach was made.
Given the method used to protect the usernames and passwords, the data can be considered accessible and it is almost certain the person or persons responsible for the attack will attempt to monetize the data. If the attacker cannot personally decrypt the data, it is certain that the data will be some to someone who can.
While it is possible that the bcrypt-encrypted passwords can be decoded, it is unlikely that decryption will be attempted. To do so would take a considerable amount of time and effort. Further, Under Armour is notifying affected users and is encouraging them to change their passwords as a precaution to ensure accounts cannot be accessed.
While MyFitnessPal accounts may remain secure, that does not mean that users of MyFitnessPal will be unaffected by the breach. The attacker – or current holders of the data – will no doubt use the 150 million email addresses and usernames for phishing campaigns.
Under Armour started notifying affected users four days following the MyFitnessPal data breach. Any user affected should login and change their password as a precaution to prevent their account from being accessed. Users also need to be alert to the risk from phishing.
Phishing campaigns related to the MyFitnessPal data breach can be expected although the attackers will likely develop a variety of phishing emails to target breach victims.
An incident of the scale of the MyFitnessPal data breach also poses a risk to businesses. If an employee was to respond to a phishing campaign, it is possible that they could download malware onto their work device – an action that could result in the business network being compromised.
Attacks on this scale are becoming far more common, and with huge volumes of email addresses now being used for phishing campaigns, advanced spam filtering solutions for businesses are now a necessity.
If you have yet to implement a spam filter, are unhappy with your current provider and the detection/false positive rate, contact TitanHQ to find out about SpamTitan – The leading anti-spam software for enterprises and SMBs.
A recent Lazio phishing scam has potentially resulted in a €2 million loss for the Italian Serie A football team, which made the final installment of a transfer of a football player to the bank account of a scammer.
The Lazio phishing scam involved some insider knowledge as the scammer was aware that part of the transfer fee for a player was outstanding. An email was carefully crafted and sent to the Italian football team that appeared to have come from representatives of the Dutch football club Feyenoord. In the email the outstanding balance for the player Stefan de Vrij was demanded. Stefan de Vrij had joined Lazio from Feyenoord in 2014.
The email looked official and appeared to have been sent from a legitimate source. The accounts department at the Italian club responded and proceeded with the transfer of funds – approximately $2,460,840 – to the bank account as requested. However, the bank account details supplied in the email were not those of Feyenoord.
When Feyenoord was contacted, the club denied all knowledge of any email communication about the player and confirmed that no funds had been received. The money had been paid to a Dutch bank account, but not one held by any staff at the club, nor any representative of the player.
The payment has been tracked and Lazio is attempting to recover the funds. It is not yet known whether the money has been recovered and if that will be possible.
The Lazio phishing scam has certainly made the headlines, but many similar attacks go unreported. Scams such as this are commonplace, and businesses are being fooled into making huge transfers of funds to criminals’ accounts.
While this attack clearly involved some insider knowledge, that information can easily be gained with a simple phishing email. If the CFO of an organization can be fooled into revealing their email login credentials, the account can be accessed and a treasure trove of information can be found. The account can then be used to send an email request to a member of the accounts department or a company that is in the process of making a sizeable purchase.
The attacker can match the writing style of the CTO and copy the usual format of email requests. All too often the recipient is fooled into making the transfer.
This type of scam is called business email compromise – or BEC – and it is costing businesses billions. One recent report estimates the total losses to BEC attacks alone is likely to reach $9 billion in 2018.
These scams are far different to the typical phishing scams of years gone by where huge numbers of emails were sent in the hope of a few individuals responding. These attacks are highly targeted, the recipient is extensively researched, and a great deal of time is spent conducting the attack. As the Lazio phishing scam showed, it is certainly worth the time and effort.
Businesses need to protect themselves against these types of phishing attacks, but there is no silver bullet. Layered defenses are essential. Businesses need to develop an anti-phishing strategy and purchase anti-phishing security solutions. An advanced spam filtering solution is a must, DMARC should be implemented to prevent brand abuse, and security awareness training for staff is essential. Policies should also be developed and implemented that require two-factor verification on any wire transfer over a certain threshold.
Even if an email filter could not block the Lazio phishing email and the email was so believable to fool a security aware employee, a quick telephone call to confirm the request could have highlighted the scam for what it was.
Several new AutoHotKey malware variants have been discovered in recent weeks as threat actors turn to the scripting language to quickly develop new malware variants. The latest discovery – Fauxpersky malware – is very efficient at stealing passwords.
AutoHotKey is a popular open-source scripting language. AutoHotKey make it easy to create scripts to automate and schedule tasks, even inside third-party software. It is possible to use AutoHotKey to interact with the local file system and the syntax is simple, making it straightforward to use, even without much technical knowledge. AutoHotKey allows scripts to be compiled into an executable file that can be easily run on a system.
The usefulness of AutoHotKey has not been lost on malware developers, and AutoHotKey malware is now used for keylogging and to install other malware variants such as cryptocurrency miners, the first of the latter was discovered in February 2018.
Several other AutoHotKey malware variants have since been discovered with the latest known as Fauxpersky, so named because it masquerades as Kaspersky antivirus.
Fauxpersky malware lacks sophistication, but it can be considered a significant threat – One that has potential to cause considerable harm. If undetected, it allows the attackers to steal passwords that can be used for highly damaging attacks and give the attackers a foothold in the network.
Fauxpersky malware was discovered by security researchers Amit Serper and Chris Black. The researchers explained in a recent blog post that the malware may not be particularly advanced and stealthy, but it is a threat and could allow the authors to steal passwords to gain access to data.
Fauxpersky infects USB drives which are used to spread the malware between devices. The malware can also replicate across the system’s listed drives. Communication with the attackers is via a Google Form, that is used to send stolen passwords and keystroke lists to the attackers’ inbox. Since the transmission is encrypted, it doesn’t appear to be data exfiltration by traffic monitoring systems.
Once installed it renames the drive and appends “Protected y Kaspersky Internet Security 2017” to the drive name. The malware records all keystrokes made on a system and also adds context to help the attackers determine what the user is doing. The name of the window where the text is being typed is added to the text file.
Once the list of keystrokes has been sent, it is deleted from the hard drive to prevent detection. The researchers reported the new threat to Google which rapidly took down the malicious form although others may well be created to take its place.
AutoHotKey Malware Likely to become More Sophisticated
AutoHotKey malware is unlikely to replace more powerful scripting languages such as PowerShell, although the rise in use of AHK and the number of new variants detected in recent weeks suggest it will not be dropped any time soon. AHK malware has now been discovered with several obfuscation functions to make it harder to detect, and many AV vendors have yet to implement the capability to detect this type of malware. In the short to medium term, we are likely to see an explosion of AHK malware variants, especially keyloggers designed to steal passwords.
A disaster recovery plan will help to ensure your business continues to function when disaster strikes, and you can recover as quickly as possible. Developing a disaster recovery plan in advance is essential as it will allow you to prevent many lost hours in the early stages of an attack when rapid action is critical.
When Disaster Strikes You Must be Ready for Action
When disaster strikes, you need to act fast to get your systems back online and return to normal business operations. One of the biggest problems for many organizations, is the amount of time that is lost immediately after a cyberattack is discovered. When staff are scrambling around not knowing what to do, precious minutes, hours, and even days can be lost.
The first few hours after a cyberattack can be critical. The time it takes to respond can have a significant impact on the cost of mitigating the attack and the harm caused. In the case of ransomware, that could be movement within your network, with one infected endpoint becoming two, then 4, then 8 and so on until files on your entire network are encrypted. Each lost minute can mean hours of extra work and major productivity losses.
The only way to ensure the fastest possible response is to be prepared for the unexpected. That means you must have a disaster recovery plan formulated that is easily accessible and can be followed by all staff involved in the breach response. Staff not responsible for recovery must be aware how they must operate in the absence of computers and critical systems to ensure the business does not grind to a halt.
Developing a Disaster Recovery Plan
There are many potential disaster scenarios. Natural disasters such as earthquakes, floods, tornados can cause major disruption, as can terrorist attacks and sabotage. The most likely disaster scenario in the current climate is a cyberattack.
All of these disaster scenarios threaten your systems and business data, so your disaster recovery plan must ensure your systems are protected and the confidentiality, integrity, and availability of data is safeguarded while you respond.
While the threat may be similar for all scenarios, priorities will be different for each situation and the order of actions and the actions themselves will be specific to different threats. It is therefore essential to plan for each of the likely disasters and to develop procedures for each. For example, your plan should cover a cyberattack affecting each specific location that you operate, and a separate plan developed for a ransomware attack, malware infection, and system outage.
Assess Business Impact and Set Priorities
A cyberattack could take out multiple systems which will all need to be restored and brought back online. That process could take days or weeks, but some systems must take priority over others. After your disaster recovery policy has been developed, you must set priorities. To effectively prioritize you will need to perform a business impact analysis on all systems. You should conduct a BIA to determine the possible financial, safety, contractual, reputational, and regulatory impact of any disaster and assess the impact on confidentiality, integrity, and availability of data. When the BIA has been completed, it should make it clear what the priorities are for recovery.
Everyone Must Know Their Role
When disaster strikes, everyone in the IT department must be aware of their responsibilities. You must know who will need to be called in when the attack occurs outside office hours, which means you must maintain up to date contact information such as phone numbers, addresses, and email addresses. You will also need to have a list of contractors and cybersecurity firms that can assist. You must know which law enforcement agencies to contact and any regulators or authorities that should be notified. All employees within the organization must be aware how their day-to-day activities will change and the role they will play, and what you will say to your customers, clients, and business associates.
Testing, Testing, Testing
You will naturally have developed a disaster recovery plan and emergency mode operations plan, but those plans rarely need to be put into action. You therefore need to be 100% sure that your disaster recovery plan developed a couple of years previously will work as planned. That is unlikely unless it is thoroughly tested and is regularly updated to take hardware, software, and business changes into account.
Your disaster recovery plan must be tested to make sure that it will work in practice. That means testing individual aspects against specific scenarios and also running through a full test – like a fire drill – to make sure that the whole plan works.
Don’t wait until disaster strikes before developing a disaster recovery plan and don’t wait for a disaster to find out all of your planning has been in vain as system changes have rendered the plan unworkable.
No matter how many cybersecurity solutions you have deployed or the maturity of your cybersecurity program, it is now essential for develop and effective security awareness program and to ensure all employees and board members are trained how to recognize email threats.
Threat actors are now using highly sophisticated tactics to install malware, ransomware, and obtain login credentials and email is the attack method of choice. Businesses are being targeted and it will only be a matter of time before a malicious email is delivered to an employee’s inbox. It is therefore essential that employees are trained how to recognize email threats and told how they should respond when a suspicious email arrives in their inbox.
The failure to provide security awareness training to staff amounts to negligence and will leave a gaping hole in your security defenses. To help get you on the right track, we have listed some key elements of an effective security awareness program.
Important Elements of an Effective Security Awareness Program
Get the C-Suite Involved
One of the most important starting points is to ensure the C-Suite is on board. With board involvement you are likely to be able to obtain larger budgets for your security training program and it should be easier to get your plan rolled out and followed by all departments in your organization.
In practice, getting executives to support a security awareness program can be difficult. One of the best tactics to adopt to maximize the chance of success is to clearly explain the importance of developing a security culture and to back this up with the financial benefits that come from having an effective security awareness program. Provide data on the extent that businesses are being attacked, the volume of phishing and malicious emails being sent, and the costs other businesses have had to cover mitigating email-based attacks.
The Ponemon Institute has conducted several major surveys and provides annual reports on the cost of cyberattacks and data breaches and is a good source for facts and figures. Security awareness training companies are also good sources of stats. Present information clearly and show the benefit of the program and what you require to ensure it is a success.
Get Involvement from Other Departments
The IT department should not be solely responsible for developing an effective security awareness training program. Other departments can provide assistance and may be able to offer additional materials. Try to get the marketing department on board, human resources, the compliance department, privacy officers. Individuals outside of the security team may have some valuable input not only in terms of content but also how to conduct the training to get the best results.
Develop a Continuous Security Awareness Program
A one-time classroom-based training session performed once a year may have once been sufficient, but with the rapidly changing threat landscape and the volume of phishing emails now being sent, an annual training session is no longer enough.
Training should be an ongoing process provided throughout the year, with up to date information included on current and emerging threats. Each employee is different, and while classroom-based training sessions work for some, they do not work for everyone. Develop a training program using a variety of training methods including annual classroom-based training sessions, regular computer-based training sessions, and use posters, games, newsletters, and email alerts to keep security issues fresh in the mind.
Use Incentives and Gamification
Recognize individuals who have completed training, alerted the organization to a new phishing threat, or have scored highly in security awareness training and tests. Try to create competition between departments by publishing details of departments that have performed particularly well and have the highest percentage of employees who have completed training, have reported the most phishing threats, scored the highest in tests, or have correctly identified the most phishing emails in a round of phishing simulations.
Security awareness training should ideally be enjoyable. If the training is fun, employees are more likely to want to take part and retain knowledge. Use gamification techniques and choose security awareness training providers that offer interesting and engaging content.
Test Employees Knowledge with Phishing Email Simulations
You can provide training, but unless you test your employees’ security awareness you will have no idea how effective your training program has been and if your employees have been paying attention.
Before you commence your training program it is important to have a baseline against which you can measure success. This can be achieved using security questionnaires and conducting phishing simulation exercises.
Conducting phishing simulation exercises using real world examples of phishing emails after training has been completed will highlight which employees are security titans and which need further training. A failed phishing simulation exercise can be turned into a training opportunity.
Comparing the before and after results will show the benefits of your program and could be used to help get more funding.
Train your staff regularly and test their understanding and in a relatively short space of time you can develop a highly effective human firewall that complements your technological cybersecurity defenses. If a malicious email makes it past your spam filter, you can be confident that your employees will have the skills to recognize the threat and alert your security team.
A city of Atlanta ransomware attack has been causing havoc for city officials and Atlanta residents alike. Computer systems have been taken out of action for several days, with city workers forced to work on pen and paper. Many government services have ground to a halt as a result of the attack.
The attack, like many that have been conducted on the healthcare industry, involved a variant of ransomware known as SamSam.
The criminal group behind the attack is well known for conducting attacks on major targets. SamSam ransomware campaigns have been conducted on large healthcare providers, major educational institutions, and government organizations.
Large targets are chosen and targeted as they have deep pockets and it is believed the massive disruption caused by the attacks will see the victims pay the ransom. Those ransom payments are considerable. Demands of $50,000 or more are the norm for this group. The City of Atlanta ransomware attack saw a ransom demand issued for 6 Bitcoin – Approximately $51,000. In exchange for that sum, the gang behind the attack has offered the keys to unlock the encryption.
SamSam ransomware attacks in 2018 include the cyberattack on the electronic health record system provider Allscripts. The Allscripts ransomware attack saw its systems crippled, with many of its online services taken out of action for several days preventing some healthcare organizations from accessing health records. The Colorado Department of Transportation was also attacked with SamSam ransomware.
SamSam ransomware was also used in an attack on Adams Memorial Hospital and Hancock Health Hospital in Indiana, although a different variant of the ransomware was used in those attacks.
A copy of the ransom note from the city of Atlanta ransomware attack was shared with the media which shows the same Bitcoin wallet was used as other major attacks, tying this attack to the same group.
SecureWorks, the cybersecurity firm called in to help the City of Atlanta recover from the attack, has been tracking the SamSam ransomware campaigns over the past few months and attributes the attacks to a cybercriminal group known as GOLD LOWELL, which has been using ransomware in attacks since 2015.
While many ransomware attacks occur via spam email with downloaders sent as attachments, the GOLD LOWELL group is known for leveraging vulnerabilities in software to install ransomware. The gang has exploited vulnerabilities in JBoss in past attacks on healthcare organizations and the education sector. Flaws in VPNs and remote desktop protocol are also exploited.
The ransomware is typically deployed after access to a network has been gained. SecureWorks tracked one campaign in late 2017 and early 2018 that netted the gang $350,000 in ransom payments. The earnings for the group have now been estimated to be in the region of $850,000.
Payment of the ransom is never wise, as this encourages further attacks, although many organizations have no choice. For some, it is not a case of not having backups. Backups of all data are made, but the time taken to restore files across multiple servers and end points is considerable. The disruption caused while that process takes place and the losses suffered as a result are often far higher than any ransom payment. A decision is therefore made to pay the ransom and recover from the attack more quickly. However, the GOLD LOWELL gang has been known to ask for additional payments when the ransom has been paid.
The city of Atlanta ransomware attack commenced on Thursday March 22, and with the gang typically giving victims 7 days to make the payment. The city of Atlanta only has until today to make that decision before the keys to unlock the encryption are permanently deleted.
However, yesterday there were signs that certain systems had been restored and the ransomware had been eradicated. City employees were advised that they could turn their computers back on, although not all systems had been restored and disruptions are expected to continue.
As of today, no statement has been released about whether the ransom was paid or if files were recovered from backups.
How to Defend Against Ransomware Attacks
The city of Atlanta ransomware attack most likely involved the exploitation of a software vulnerability; however, most ransomware attacks occur as a result of employees opening malicious email attachments or visiting hyperlinks sent in spam emails.
Last year, 64% of all malicious emails involved ransomware. An advanced spam filter such as SpamTitan is therefore essential to prevent attacks. End users must also be trained how to recognize malicious emails and instructed never to open email attachments or click on links from unknown senders.
Software must be kept up to date with patches applied promptly. Vulnerability scans should be conducted, and any issues addressed promptly. All unused ports should be closed, RDP and SMBv1 disabled if not required, privileged access management solutions deployed, and sound backup strategies implemented.
2017 ransomware statistics do not make for pleasant reading. Ransomware attacks continued to increase, the cost of mitigating attacks rose, and the number of ransomware variants in use has soared. Further, there are no signs that the attacks will stop and mounting evidence that the ransomware epidemic will get worse in 2018.
Key 2017 Ransomware Statistics
We have compiled some of the important 2017 ransomware statistics from research conducted by a range of firms over the past few months.
Kaspersky Lab’s research suggests ransomware attacks on businesses were happening every 2 minutes in Q1, 2017, but by Q3 attacks were far more frequent, occurring approximately every 40 seconds. Cybersecurity Ventures predicts the frequency of attacks will increase and by 2019 there will be an attack occurring every 14 seconds.
Cybersecurity Ventures also predicts ransomware will continue to be a major problem for businesses throughout 2018 and 2019, with the total cost of ransomware attacks expected to reach $11.5 billion by 2019.
The healthcare industry is likely to be heavily targeted due to the relative ease of conducting attacks and the likelihood of a ransom being paid. Cybersecurity Ventures predicts there will be a fourfold increase in ransomware attacks on healthcare organizations by 2019.
While research from IBM in 2016 suggested 70% of businesses pay ransom demands to recover data, in 2017 the percentage dropped considerably. Far fewer firms are now considering paying ransoms to recover data.
Symantec’s 2017 Internet Security Threat Report indicates ransom demands increased by 266% between 2015 and 2017.
There is considerable variation in published 2017 ransomware statistics. Malwarebytes reports there was a 90% increase in ransomware attacks in 2017. Beazley reports the increase was 18% and the healthcare sector accounted for 45% of those attacks. A recent McAfee Report puts the rise in ransomware attacks at 59% for the year, with a 35% quarter-over-quarter increase in attacks in Q4.
Microsoft’s Security Intelligence Report indicates Asia had the highest number of ransomware attacks in 2017, with Myanmar and Bangladesh the worst hit countries. Mobile devices that were the worst hit, with the most frequently encountered ransomware variant being LockScreen – an Android ransomware variant.
55% of Firms Experienced A Ransomware Attack in 2017
The research and marketing consultancy firm CyberEdge Group conducted a study that showed 55% of surveyed organizations had experienced at least one ransomware attack in 2017. Out of the organizations that had data encrypted by ransomware, 61% did not pay the ransom.
87% of firms that experienced an attack were able to recover the encrypted data from backups. However, 13% of attacked firms lost data due to the inability to recover files from backups.
Organizations that are prepared to pay a ransom are not guaranteed viable keys to recover their encrypted files. The CyberEdge survey revealed approximately half of companies that decided to pay the ransom were unable to recover their data.
FedEx reported in 2017 that the NotPetya attack cost the firm an estimated $300 million, the same figure quoted by shipping firm Maersk and pharma company Merck. Publishing firm WPP said its NotPetya attack cost around $15 million.
Strategies are being developed by businesses to respond to ransomware attacks quickly. Some companies, especially in the UK, have bought Bitcoin to allow fast recovery. However, those that have may find their stash doesn’t go as far as it was first thought thanks to the decline in value of the cryptocurrency. Further, many cybercriminals have switched to other forms of cryptocurrency and are no longer accepting Bitcoin. A third of mid-sized companies in the UK have purchased Bitcoin for ransoms according to Exeltex Consulting Group.
The cybersecurity threat level is at an all time high, according to a recently published threat report from McAfee. The AV solution provider has compiled a report from data collected over the final quarter of 2017 which shows the last three months of 2017 saw record numbers of new malware samples detected – 63.4 million samples. A level never before seen.
The soaring value of Bitcoin and other cryptocurrencies in the final quarter of 2017 fueled a massive rise in cryptocurrency hijacking and the use of cryptocurrency miners over other forms of malware that were favored in previous quarters. With Bitcoin valued at $19,000 in December and cryptocurrency mining hardware costing several thousand dollars, it is no surprise that so many threat actors chose to hijack other computers and steal money from cryptocurrency wallets.
Cryptocurrency miners were being used in spam email campaigns, disguised as mobile apps, and there was a massive rise in the hijacking of websites and loading cryptocurrency mining code.
While mining cryptocurrencies has proven to be highly profitable for cybercriminals, they did not abandon the use of other malware variants. The use of ransomware continues to increase, with spam email the primary method of delivery.
McAfee reports that there was 35% ransomware growth in Q4, and 59% growth in 2017. For the fourth consecutive quarter there has been an increase in new ransomware variants, with much of the increase due to the widespread use of Ransom:Win32/Genasom. There is unlikely to be a fall in use of ransomware any time soon.
The use of spam email to deliver malware and ransomware continues to grow, with two botnets – Necurs and Gamut – responsible for delivering 97% of all spam email in Q4, with the former now the most prevalent spamming botnet.
Botnets are also being developed to exploit IoT devices, which typically lack security and often have poor passwords. Infecting the devices allows massive botnets to be easily assembled for use in DDoS and DoS attacks.
Q4 was the fourth consecutive quarter where new malware samples have continued to increase, with total malware samples now just short of 700,000,000. New Mac malware also increased for the third consecutive quarter and there are now approximately 750,000 Mac malware variants, although there was a fall in new mobile malware samples from the 2-year high in Q3.
There was a rise in new Faceliker and macro malware, although the biggest increase was PowerShell malware. Q4 saw a massive jump in new PowerShell downloaders.
While the cybersecurity threat level continues to increase, and all industries are at risk, healthcare was the most targeted industry in 2017 by some distance. Healthcare may have been the third most targeted industry sector in 2016-2017, but the first three quarters of 2017 saw more than twice as many attacks on healthcare organizations than any other industry sector.
McAfee reports that there has been a 210% increase in cybersecurity incidents reported by healthcare organizations in 2017 compared to 2016, although there was some respite in Q4, which saw a 78% quarter over quarter decline in security incidents.
McAfee suggests it is poor security practices that have contributed to the rise in healthcare data breaches and cyberattacks. Many of the reported incidents could have been prevented if cybersecurity best practices had been followed.
There have been several major cyberattacks on restaurants in recent months. Organized cybercriminals gangs are using specially crafted malware to silently steal credit card data from POS systems. Not only do the initial intrusions go undetected, the presence of the malware is often not detected for several months, during which time tens of thousands of credit card details are stolen.
Last month saw another large restaurant chain suffer a major breach of payment card data. The cyberattack on Applebee’s affects more than 160 of its RMH Franchise Holdings owned and operated restaurants across 15 states.
Customers who visited one of the RMH restaurants in Alabama, Arizona, Texas, Florida, Illinois, Indiana, Kansas, Kentucky, Ohio, Mississippi, Missouri, Nebraska, Oklohoma, Pennsylvania or Wyoming between November 2017 and January 2018 and paid for their meal on a credit or debit card have potentially had their card details stolen. Customers who paid using the self-pay tabletop devices were not affected, and neither were customers who paid online. The data breach was confined to RMH-operated restaurants. Other restaurants in the Applebee’s network were unaffected.
The data theft occurred as a result of malware on its POS system. The malware had been developed to capture data such as card numbers, expiry dates, CVV codes, and cardholder names. After recording the data, the information was exfiltrated to the attacker’s command and control server.
RMH reports that it has security systems in place to prevent cyberattacks and was able to contain the incident prior to discovery of malware on February 13, 2018. One a breach was discovered, RMH conducted a thorough investigation to identify the full extent of the breach and the individuals potentially impacted. A leading computer forensics firm was contracted to assist with the investigation and help mitigate of the attack. RHM has not disclosed how the malware was installed and nether the type of malware used in the attack.
The Applebee’s cyberattack is the latest in a string of cyberattacks on restaurants and retailers. In 2017 there were similar cyberattacks on restaurants throughout the United States. Arby’s fast food restaurants experienced a POS-malware related breach that affected many of its 1,000+ corporate stores. Chipotle Mexican Grill discovered malware had been installed on its POS system, with most of its stored affected over a 1-month period last spring.
Retailers are also major targets. Earlier this year, the retailer Forever21 discovered malware has been installed on its POS system. It took the retailer 7 months to identify the breach, during which time the credit and debit card details of many thousands of its customers were stolen.
Last year, many of the 750 Kmart stores were infected with POS malware – the second major credit card breach experienced by the chain in the past three years. Buckle Inc., was also attacked, with an undisclosed number of its stores affected. The malware infection remained on its system undetected for more than 5 months.
The breaches highlight the importance of implementing layered defenses to protect the entire attack surface, from spam email defenses to web filters, next generation firewalls, and advanced intrusion detection systems. It is also essential for retailers and restaurateurs to conduct regular vulnerability scans of the entire network to identify and address security flaws, with technical solutions implemented to constantly monitor POS systems for signs of compromise.
A massive campaign spreading the Dofoil Trojan has been detected by Microsoft. The campaign has already seen almost half a million PCs infected with the malware in just 12 hours. The Dofoil Trojan is otherwise known as Smoke Loader – a downloader that has been active for several years.
The Dofoil Trojan is a small application which once installed on a PC is capable of downloading other forms of malware. The Dofoil Trojan has been used in various campaigns since at least 2011 to install malware, with the latest campaign used to install cryptocurrency mining malware.
More than 400,000 Dofoil Trojan Infections Detected in Just 12 Hours
The alarm was raised on March 6 when Windows Defender detected around 80,000 instances of the Trojan on PCs with the number rising rapidly to well over 400,000 in the following 12 hours. Several variants of the Dofoil Trojan were being used in the campaign which was mostly targeting devices in Russia, Ukraine, and Turkey.
The cryptocurrency mining malware is being used to mine Electroneum coins on infected devices, although the malware can mine various different cryptocurrencies.
Detecting the malware can be difficult as it uses process hollowing to create a new instance of a legitimate Windows process for malicious purposes. In this case the malware is disguised as a Windows binary file to avoid detection – wuauclt.exe. Explorer.exe is used to create a copy of the malware in the Roaming AppData folder which is renamed ditereah.exe. The Windows registry is also altered to ensure persistence, modifying an existing entry to point to the malware copy. The malware communicates with its C2 server and is also capable of installing further malware variants onto an infected device.
While Microsoft was able to detect infections, what is not known at this stage is how the malware was installed on so many devices in such as short space of time. While the malware could potentially have been distributed by spam email, another means of distribution is suspected. Microsoft notes that in several cases the malware is believed to have been spread via torrent files, which are used in P2P file sharing, often to obtain pirated movies, music, and software.
Microsoft has only reported on the number of infections it has detected via Windows Defender. The company does not have visibility into devices that do not have the anti-malware software installed. The total number of infections is therefore likely to be far greater. The 400,000+ infections are likely to be just the tip of the iceberg.
Microsoft notes that its efforts to disrupt the operation did not just stop devices from mining cryptocurrencies. Infection with the Dofoil Trojan allows the attackers to download any number of additional malicious payloads including more dangerous malware variants and ransomware.
More than 50,000 Websites Discovered to Host Cryptocurrency Mining Malware
These sites do not result in infection with malware. Typically, the only problems experienced by website visitors is a slowing down of their computers. However, in some cases, the malware has been configured to take full advantage of visitors’ computers and some hardware damage has been caused as a result.
Since it is difficult to determine which sites have been infected or are using cryptocurrency miners, the solution for users is to use a browser extension such as minerBlock to prevent the scripts from running. Users of the Opera browser need do nothing as the browser already blocks cryptocurrency mining scripts from running.
Phishing attacks in healthcare are to be expected. Healthcare providers hold vast quantities of data on patients. Hospitals typically employ hundreds or thousands of members of staff, use many third-party vendors, and historically they have had relatively poor cybersecurity defenses compared to other industry sectors. That makes them an attractive target for phishers.
Phishing is a method of gaining access to sensitive information which typically involves a malicious actor sending an email to an employee in which they attempt to get that individual to reveal their login credentials. This is achieved using social engineering techniques to make the email recipient believe the email is a genuine. For instance, a security alert could inform the email recipient that an online account has been compromised and a password change is required. They are directed to a spoofed website where they are asked to login. The site is fake but looks genuine.
Credentials are entered and passed to the attacker who uses them to gain access to that individual’s account. Phishing can also involve malware. Emails attempt to convince the recipient to open a malware-infected attachment or download a malicious file from a compromised website.
Compliance with HIPAA Rules Helps to Prevent Phishing Attacks in Healthcare
HIPAA Rules require healthcare providers to implement administrative, technical, and physical safeguards to reduce the risk of cyberattacks and phishing. HIPAA only demands a minimum standard for data security be reached, although complying with HIPAA Rules can help to prevent phishing attacks in healthcare.
HIPAA is not technologically specific on the defenses that should be used to protect patient data. Healthcare providers can choose appropriate defenses based on the results of a risk analysis.
It is possible for healthcare organizations to be compliant with HIPAA Rules but still be vulnerable to phishing attacks. If healthcare providers are to block the majority of phishing attacks and truly secure patients’ data, they must go above and beyond the requirements of HIPAA.
HHS’ Office for Civil Rights Warns of Phishing Attacks in Healthcare
Recent phishing attacks in healthcare have prompted the HHS’ Office for Civil Rights to issue a warning about the risk from phishing.
Attacks are now highly sophisticated and can be hard to detect. The emails are often free from spelling mistakes, have near perfect grammar, include brand images and logos, and appear to have been sent from genuine domains. The reasons given for taking a specific course of action are perfectly plausible as is the need for urgent action.
OCR also highlights the rise in spear phishing attacks in healthcare. These attacks involve more targeted attempts to gain access to sensitive information and can be conducted on specific individuals or groups of individuals in an organization – The payroll or HR department for instance.
These attacks often see a CEO or superiors impersonated to add legitimacy to the attack. These attacks tend to require the opening of attachments or visiting links to download malware. Spear phishing emails are also used to request bank transfers or for sensitive information to be sent via email – W2-Forms of employees for instance. Many healthcare employees have been fooled by these scams.
Recent Phishing Attacks in Healthcare
Listed below are some of the recent examples of phishing attacks in healthcare. This is just a small selection of incidents that have resulted in healthcare records being exposed or stolen. The reality is that many data breaches start with a phishing email. Security awareness training company Cofense suggests that as many as 91% of data breaches have their root in a phishing campaign.
November 2017: 1,670 patients of Forrest General Hospital have their PHI exposed following a phishing attack on business associate HORNE.
October 2017: Henry Ford Health System discovers several email accounts were compromised as a result of employees responding to phishing emails. The PHI of 18,470 patients may have been stolen.
September 2017: Employees of UPMC Susquehanna responded to phishing emails with the attackers able to gain access to the PHI of 1,200 patients.
September 2017: A phishing attack on Wisconsin-based Network Health resulted in the PHI of approximately 51,000 patients being exposed.
August 2017: Chase Brexton Health Care in Maryland experienced a phishing attack that saw several email accounts compromised along with the PHI of 16,000 patients.
July 2017: The Medical College of Wisconsin experienced a phishing attack that allowed attackers to gain access to email accounts and the PHI of 9,500 patients.
July 2017: RiverMend Health employees responded to phishing emails and their accounts were accessed by the attackers. The PHI of 1,200 patients was potentially viewed or stolen.
June 2017: A phishing attack on Elderplan Inc., saw several email accounts compromised along with the PHI of 22,000 individuals.
June 2017: MJHS Home Care experienced a phishing attack that saw email access gained by an unauthorized individual. The compromised email accounts contained the PHI of 6,000 patients.
Staff Training and Anti-Phishing Technology
HIPAA does not specifically mention spam filters, but since phishing is used to target employees via email, spam filtering can be considered essential. By filtering out the majority of spam and malicious messages there is less potential for an employee to click on a malicious link or open a malware infected email attachment.
SpamTitan is a cloud-based anti-spam service that blocks more than 99.9% of spam emails from being delivered to inboxes and has a 0.03% false positive rate. Dual antivirus engines (Bitdefender/ClamAV) ensure malicious email attachments are blocked.
Healthcare employees are the last line of defense, so it is important for them to be able to recognize email threats and anti-phishing training is a requirement of HIPAA. In July 2017, OCR issued advice to healthcare organizations on anti-phishing training in its cybersecurity newsletter.
OCR also recommends using multi-factor authentication to ensure email accounts are not compromised when a password is guessed or stolen. Software and operating systems must be kept up to date and fully patched to prevent vulnerabilities from being exploited, and anti-virus and anti-malware solutions should be deployed to prevent infection. Regular backups can also prevent data loss in the event of a malware or ransomware infection.
Titan HQ has announced from March 5, 2018 all new customers signing up to use the SpamTitan cloud-based anti-spam service will benefit from leading antivirus and anti-malware protection from Bitdefender. All existing customers will similarly be protected by Bitdefender, although first they will need to upgrade to SpamTitan v7.00. v7.00 was released on March 5.
The primary AV engine used in previous versions of SpamTitan was provided by Kaspersky Lab, with ClamAV used as a secondary AV engine. SpamTitan v7.00 will also incorporate ClamAV as a secondary AV engine. Kaspersky AV will no longer be supported on SpamTitan suite of products from May 1, 2018.
The change to the new primary AV engine is due to a growing strategic relationship with Bitdefender. Further collaboration with the Romanian cybersecurity firm is planned for the future. Customers already using SpamTitan are encouraged to upgrade to the latest version of the product as soon as possible as several other updates have been incorporated into the latest version, including patches for recently discovered vulnerabilities in ClamAV.
These include the use-after-free vulnerability CVE-2017-12374; buffer overflow vulnerabilities CVE-2017-12375 and CVE-2017-12376; Mew Packet Heap Overflow vulnerability CVE-2017-12377; Buffer Overflow in messageAddArgument vulnerability CVE-2017-12379; and Null Dereference vulnerability CVE-2017-12380. TitanHQ has also included patches for openssl, openssh, php, and wget and updates have been included to resolve potential denial of service attacks.
Customers already on v6.x of the platform who have enabled prefetch of system updates will find the latest patches in the list of available updates on the System updates page. If this option is disabled, they should use the ‘Check for Updates Now’ option in the user interface.
Customers using SpamTitan v4 and v5 have been advised that support for both versions of SpamTitan will cease on May 1, 2018. An upgrade to version 7.00 will therefore be required before the deadline. It is important to note that the update process requires v4/5 to first be upgraded to v6 before installing SpamTitan v7.00. Upgrading to the new version will not change the existing configuration of the product.
Customers should allow 10-20 minutes for the installation of the new version and should read all product notes before installation.
This month Adobe patched a critical use-after-free vulnerability in Adobe Flash Player that affects Windows 10, Mac, Chrome, and Linux operating systems. If exploited, an attacker can gain full control of an unpatched device.
Adobe reports that an exploit for the vulnerability – tracked as CVE-2018-4878 – has been identified and is being used in attacks on Windows 10 devices.
At the time that the patch was issued, only a limited number of attacks had been detected. However, researchers at Morphisec report the vulnerability is now being exploited in a massive spam email campaign that is targeting users in the United Kingdom and United States. While the spam campaign was relatively short-lived, large quantities of emails were sent and further spam campaigns can be expected.
The emails include a shortlink which, if clicked, downloads a Word document from a recently registered domain. Opening the document sees a command prompt opened that is injected with Shellcode that connects to the attackers’ C2. Once a connection is made, a DLL file is downloaded and executed using regsvr32. According to Morphisec this bypasses whitelisting solutions. A SWF Flash file is then extracted which also had a low detection rate and the vulnerability is exploited.
What makes the attack particularly dangerous is the poor detection rate by AV solutions. In a recent blog post Morphisec said in its tests, only 1/67 AV firms on VirusTotal identified the email attachment as malicious.
The shortened goo.gl URLs used in the emails are difficult to detect as malicious and look similar to those used in legitimate email campaigns. The number of links being opened also corresponds with standard email campaigns, with high numbers of clickthroughs as the emails hit inboxes. The figures show that many email recipients have been fooled by the campaign.
This email campaign shows why it is so important for patches to be applied promptly, especially when there are active exploits for a vulnerability in the wild. This is just one campaign, and there are likely to be many conducted using the Flash exploit.
However, despite the risks from slow patching, many companies take weeks, months, or in some cases years before patches are applied, leaving them extremely vulnerable to attack.
A Colorado Department of Transportation ransomware attack on February 21, 2018 affected at least 21 computers preventing files from being accessed by employees. A prompt response to the ransomware attack limited the harm caused, although to prevent the spread of the ransomware more than 2,000 computers were shut down.
The attack has already caused considerable disruption, which is ongoing as the cleanup operation continues.
The DOT says it received a ransom demand which would need to be paid in order to obtain the keys to unlock encrypted files, but that the DOT has no intention of paying any money to the attackers. Instead the firm has called in an external cybersecurity firm (McAfee) to restore data on the affected workstations and ensure all devices are clean and protected from infection. All encrypted files will be recovered from backups.
Fortunately, the ransomware attack was limited to certain endpoints. Other computer systems that are used with surveillance cameras and traffic alerts were not affected.
The Colorado Department of Transportation ransomware attack is one of several high-profile attacks involving SamSam ransomware to have been reported this year. Hancock Health Hospital in Indiana was one notable victim. The hospital was issued with a ransom demand and paid the attackers for the keys to unlock the encryption, even though backups could have been used to recover files. A Bitcoin payment worth approximately $55,000 is believed to have been paid. The payment was believed to be considerably less than the cost of disruption while files were recovered from backups.
Another Indiana hospital – Adams Memorial Hospital was also attacked with a variant of SamSam ransomware, and Allscripts – an electronic health record provider – also suffered an attack that took down some of its web services.
SamSam ransomware first surfaced in 2015, and while some antivirus and antimalware solutions can detect the malware, the attackers continue to release new variants that are much better at evading detection.
Bleeping Computer reported on January 19 that one of the Bitcoin wallets used by the gang involved in SamSam ransomware campaign had already made approximately $300,000 from ransom payments, although that figure will almost certainly be higher since multiple Bitcoin wallets are believed to be used and the campaign is ongoing.
On February 15, Secureworks reported that the profits from the attacks had increased to at least $350,000, with the firm attributing the attacks to a hacking group called Gold Lowell.
It is unclear how the Colorado Department of Transportation ransomware attack occurred. Some sources report that the attack involved phishing emails, although Gold Lowell’s modus operandi is leveraging vulnerabilities in Remote Desktop Protocol (RDP) services.
With the campaign ongoing, all businesses should be alert to the threat from phishing and RDP attacks. Spam filters, such as TitanHQ’s cloud-based anti-spam service, are essential as is anti-phishing training for employees. If RDP is necessary, strong passwords should be set and controls implemented to reduce the potential for brute force attacks. Rate limiting on login attempts for example. It is also important to make sure that multiple data backups are performed to ensure files can be recovered in the event of an attack.
A new report has been released that shows there has been a massive rise in the global cost of cybercrime, highlighting the seriousness of the threat from hackers and scammers. 2017 global cybercrime costs exceeded $600 billion, according to the McAfee report. That represents a 20% increase since 2014, when the global cybercrime costs were calculated to be around $500 billion. The current global cybercrime costs equate to 0.8% of global GDP.
The report shows that in spite of increases in cybersecurity spending, hackers and scammers are still managing to breach organizations’ defenses and gain access to sensitive data, login credentials, corporate bank accounts, and intellectual property.
Accurately Determining the Global Cost of Cybercrime
Any calculation of global cybercrime costs involves some margin of error, as the figures cannot be totally based on reported losses by businesses. Many companies do not disclose details of data breaches, and even fewer publish information of the financial impact of cyberattacks. When details about financial losses are published, typically only a fraction of the losses are reported. In many cases the losses are not known until many years after the event. It is therefore difficult to obtain a true picture of the losses due to cybercrime because of the shortage of data.
To try to gain an accurate picture of the total cost of cybercrime, McAfee had to turn to the same modelling techniques used by government agencies to determine the costs of criminal activities such as drug trafficking, prostitution, maritime piracy, and organizational crime groups.
McAfee is not the only company to make these predictions. Compared to some reports the figures from McAfee seem quite conservative. The true cost could be considerably higher.
Factors Contributing to the Increase in Losses
McAfee reports that several factors have contributed to the large increase in cybercrime costs over the past few years. The growth in popularity of ransomware has played a part. Ransomware has proved to be a particularly plump cash cow, allowing cybercriminals to rake in millions by extorting companies. The anonymity of cryptocurrencies has helped these cybercriminal gangs obtain payments without detection, while the use of TOR has helped the gangs stay under the radar of law enforcement agencies.
Ransomware-as-a-service has also boosted profits for cybercriminals. The increase in the number of individuals conducting attacks has made it possible to increase the scale of operations and distribute the malicious code more effectively. State-sponsored hacks have also increased, including attacks aimed at sabotaging businesses and critical infrastructure as well as major heists that have seen millions of dollars stolen.
McAfee cites research showing around 300,000 new malware samples are now being identified on a daily basis, while data breaches are exposing a staggering 780,000 records a day.
Personal records can sell for big bucks on darknet forums; however, one of the biggest costs is the theft of intellectual property, which McAfee estimates has resulted in at least 25% of the annual losses to cybercrime. When patented processes are obtained, the benefits of millions in research and development is lost and companies can lose their competitive advantage.
One thing is clear from the report. With global cybercrime costs rising, and the sophistication and frequency of attacks increasing, companies have little alternative than to invest more in cybersecurity and develop more sophisticated defenses.
Cybercriminal gangs operating in Nigeria have been discovered to be using phishing kits in a highly sophisticated phishing campaign that has seen millions of dollars obtained from big businesses.
The scammers are regularly fooling employees into revealing their email login credentials – The first stage of the complex scam. The ultimate goal of the attackers is to gain access to corporate bank accounts and convince accounts department employees to make sizeable transfers to their accounts.
According to research conducted by IBM, these scams have been highly successful. Fortune 500 companies are being targeted and losses have been estimated to be of the order of several million dollars.
These scams take time to pull off and considerable effort is required on the part of the scammers. However, the potential rewards are worth the effort. Bank transfers of tens or hundreds of thousands of dollars can be made and business email accounts can be plundered.
A Sophisticated Multi-Stage Phishing Scam
In order to pull off the scam, the attackers must first gain access to at least one corporate email account. Access is gained using phishing emails, with social engineering tactics used to convince employees to click on a malicious link. Those links direct the email recipients to malicious DocuSign login pages where credentials are harvested. These malicious pages have been created on multiple websites.
According to IBM, the gang behind this campaign has created more than 100 of these pages, many of which have been loaded onto genuine websites that have been compromised by the attackers.
Once access to one email account is gained, it is easy to obtain email addresses from the contact list to fool other employees. When an email account is accessed, the attackers search the account for messages involving accounts and payments. The attackers then send emails carrying on conversations between staff members, inserting themselves into conversations and continuing active discussions.
“The attackers typically took a week between the point they gained initial access to a user’s email account and the time they started setting up the infrastructure to prepare a credible ruse,” said IBM’s X-Force researchers. “During this time, they likely conducted extensive research on the target’s organizational structure, specifically focusing on the finance department’s processes and vendors.”
By setting up email rules and filters, it is possible to block genuine conversations between the employees that could uncover the scam. By doing this, all conversations take place between a specific individual and the attacker.
This method of attack allows the attackers to gain access to banking credentials and send highly convincing emails requesting transfers to their accounts. Targeted employees are unlikely to be unaware that they are not emailing a legitimate contact.
This is a manual, labor-intensive scam involving no malware. That has the advantage of allowing the attackers to evade anti-malware technologies.
How to Protect Against These Sophisticated Email Scams
While these scams are complex, they start with a simple phishing email to gain access to a corporate email account. Once access to an email account has been gained, stopping the scam becomes much harder. The easiest time to prevent such an attack is at the initial stage, by preventing the phishing emails from reaching the inboxes of employees and training employees how to identify phishing emails.
That requires an advanced spam filtering solution that can identify the common signatures of spam and scam emails. By setting aggressive filtering policies, the vast majority of spam emails will be captured and quarantined. With the SpamTitan cloud-based anti-spam service, that equates to more than 99.9% of all spam and malicious emails. SpamTitan also has a particularly low false positive rate – less than 0.03% – ensuring genuine emails are still delivered.
No spam solution can be 100% effective, so it is also important to prepare the workforce and train staff how to identify malicious emails. Security awareness and anti-phishing training allows organizations to create a ‘human firewall’ to complement technical solutions.
Spear phishing – highly targeted email attacks – are harder to block, but it is possible to implement solutions to prevent scams such as this from resulting in credentials being obtained. In this campaign, links are sent in emails. By implementing a web filtering solution, those links can be blocked. In tandem with a spam filter, organizations with a security aware workforce will be well protected from phishing attacks.
Further, the use of two-factor authentication is an important security measure to implement. This will prevent attackers from using an unknown device to access an email account.

A new IRS-themed rapid ransomware email scam has been detected that uses the threat of significant financial penalties for late tax payments to fool victims into installing ransomware.
Tax season is well underway and cybercriminals have been increasing their efforts to obtain tax credentials to file fraudulent tax returns in the names of their victims. Businesses are the prime targets, as a successful scam can see the tax credentials of hundreds or thousands of employees obtained from a single response to an scam email.
However, it is not only tax fraudsters that are taking advantage of tax season. Ransomware attacks are also likely, as has been highlighted by a recently uncovered email scam that impersonates the IRS.
The purpose of this scam is to install Rapid ransomware. Rapid ransomware is a relatively new ransomware variant first detected in January 2018. In contrast to many ransomware variants that encrypt files and then terminate, rapid ransomware remains active after encryption and will encrypt any further files that are created on the infected device.
In addition to encrypting files, the ransomware deletes Windows shadow volume copies and disables automatic repair to hamper any attempts to restore files without paying the ransom. There is currently no decryptor for Rapid ransomware. Recovery will depend on backups being available or the ransom demand must be paid.
IRS Spoofed to Spread Rapid Ransomware
The Rapid ransomware email scam is similar to many other scams conducted during tax season. The emails are well written and plausible. There is urgency to encourage rapid action and a threat of financial penalties if the emails are ignored.
The emails have the subject line: ‘Please Note – IRS Urgent Message 164’ and contain a zipped notification attachment which email recipients are required to open to obtain further information.
In the body of the email, the recipient is led to believe they have significant tax arrears related to a property. The recipient is told that no action is taken by the IRS when tax arrears are cleared within 4-6 months of their due date, but since the recipient’s tax is 7 months out of date they are liable for a fine. They are told that if they do not respond to the email within one day and attempt to rectify the situation, ‘significant charges and fines may apply’. They are also told to open and study the attached document. The zip file contains a Word file containing a macro. If allowed to run, the macro downloads a PowerShell file, which in turn downloads Rapid ransomware.
Security aware individuals should be able to identify signs that the email is not genuine. First, the email is addressed ‘Dear Customer.’ In the event of the IRS contacting an individual about tax arrears, it would be likely that the email would be addressed using the individual’s name. However, such a situation would not occur. The IRS has confirmed in numerous warnings about phishing emails that it does not initiate contact about tax arrears via email. Further, tax arrears are serious, but not so serious that a response of 1 day would be given for a response.
The scammers behind this campaign have made some glaring mistakes in their campaign. The email address spoofed has the domain nottscc.gov.uk. While the email address looks official, it relates to Nottinghamshire County Council in the UK and the IRS is the American tax agency. However, many devices do not show the full domain so this may not be noticed. Another major error is the use of German language in the Word document, including instructions for enabling the macro.
Scam Highlights Need for Spam Filters and Security Awareness Training
Due to the errors made by the scammers, in particular the use of German and a UK local government email address – this email scam should be easily detected by employees and consumers, but such mistakes are not always made. The email is plausible, and otherwise it would be likely that many individuals would be fooled by such a scam.
For businesses, these scams can prove incredibly costly. In this case, there is no set ransom payment. Victims need to email the scammers to find out how to pay the ransom and how much is being charged. If the emails come from a business domain, the ransom payment would likely be increased. Further, ransomware can spread laterally within a network and result in file encryption on multiple endpoints and servers. With ransoms typically charged for each infected device, the costs can be considerable.
This Rapid ransomware email scam highlights the need for spam protections to be put in place to prevent malicious emails from being delivered. With SpamTitan implemented, more than 99.9% of spam email is blocked, preventing employees from having their phishing email identification skills tested.
It is also important to provide security awareness training to employees to teach them the skills they need to identify scams such as this. Not all email scams will be as easy to detect as this one. Training goes a long way toward ensuring that when emails slip past security defenses they are quickly identified by the workforce.
Saturn ransomware is a new threat recently identified by security researchers at MalwareHunterTeam. Saturn ransomware takes its name from the extension added to encrypted files (.saturn).
While it is easy to determine the ransomware variant used in an attack, this will be of little use to victims. There is currently no decryptor available to recover files.
A single infection can rapidly spread laterally, encrypting files on an infected device as well as network shares. Recovering files from backups may prove difficult. Saturn ransomware searches for and deletes shadow volume copies, clears the Windows backup catalog, and also disables Windows startup repair.
If no viable backup exists, the victim must pay a ransom payment in bitcoin of approximately $300 per infected device. If payment is not made within 7 days of infection, the ransom payment doubles.
As with many new ransomware variants, attacks can come from all angles. That is because the new ransomware variant is being offered to affiliates as ransomware-as-a-service.
Ransomware-as-a-service allows the malware developers to maximize the number of infections – and profits – by recruiting a large team of distributors to send spam emails, load the ransomware onto malicious websites, and install the malicious software by taking advantage of poor security defenses. In exchange for their efforts, affiliates are given a percentage of the ransom payments that are received.
The developers of Saturn ransomware have made it as easy as possible for affiliates. A portal has been developed that allows affiliates to obtain copies of the ransomware binaryeither embedded in exe files or Office, PDF files or other documents. To tempt individuals into using this ransomware variant instead of other RaaS offerings, the developers are offering a large percentage of the ransom payments to affiliates – 70%.
The ease of running campaigns together with the high potential rewards for infection means many affiliates are likely to start using the new ransomware variant in attacks. The new malware is already being offered on various darknet forums.
How to Block Saturn Ransomware Attacks
Spam email is the easiest way of spreading ransomware. Massive spam campaigns require little skill and there is no shortage of email addresses for sale on the dark web. We can therefore expect this new ransomware variant to be widely distributed over the coming weeks.
With spam email likely to be the main vector of attack, one of the best defenses to deploy to prevent infection is to use anti spam software such as SpamTitan. SpamTitan blocks more than 99.9% of spam email. With SpamTitan in place, emails can be blocked and will not reach end users inboxes.
However, no single defense can provide total protection from ransomware attacks. Layered defenses are required. Antivirus and antimalware solutions should be used, although signature and heuristics-based defenses will not provide total protection. Businesses should also use a technology that identifies changes to files to ensure that if infection occurs, rapid action can be taken to limit the spread of the ransomware.
Multiple copies of files should also be made to ensure that should the unthinkable happen, data will not be lost. Businesses should make at least three backups, stored on two different media, with at least one copy stored securely off-site. Good patch management policies are also required to prevent vulnerabilities from being leveraged to install the ransomware.
Technical defenses are essential, but don’t forget the human element. Ransomware spread via spam email requires some user interaction – the opening of an email attachment or the clicking of a link. Security awareness training and phishing email simulations are now a necessity to reduce user susceptibility to email-based attacks.
A new malware campaign has been detected that uses Microsoft Word without macros. Opening a Word document sent via email will not generate the usual warnings that macros must be enabled.
Employees may have been warned to be wary of any emails containing attachments, and never to enable macros on documents received via email. However, the use of Microsoft Word without macros means that even opening email attachments can see malware downloaded, if patches have not been applied.
The multi-stage infection process uses the CVE-2017-11822 Word vulnerability to install an information stealer. CVE-2017-11822 was patched by Microsoft last year, although companies that have not patched their systems recently will be vulnerable to this attack.
CVE-2017-11822 is a vulnerability in Office Equation Editor. The bug has been present in Microsoft Office for the past 17 years. Last year, Microsoft rated the code execution vulnerability as important rather than critical, but many security professionals disagreed and claimed the vulnerability was very dangerous as the bug could be exploited to run arbitrary code and the vulnerability was present in all Office versions.
Microsoft Equation Editor is an application that allows the insertion and editing of complex equations in Office documents as OLE items. Last year, security researchers were able to exploit the vulnerability to run a sequence of commands, including the downloading of files from the Internet. This campaign similarly triggers the downloading of a document – a Rich Text File (RTF) via an OLE object embedded in the Word document.
The OLE object opens the RTF file which uses the vulnerability to run a MSHTA command line, which downloads and runs an HTA file containing a VBScript. The VBScript unpacks a PowerShell script, which in turn downloads and runs the information-stealing malware. The purpose of the malware is to steal passwords from web browsers, email accounts and FTP servers.
The email campaign has been developed to target businesses. So far, four email templates have been detected by SpiderLabs researchers, although more will almost certainly be used over the coming days and weeks.
The four emails intercepted by have the subject lines:
TNT Statement of Account
Request for Quotation (RFQ)
Telex Transfer Notification
Swift Copy for Balance Payment
While a patch was released last year to address the vulnerability, Microsoft has taken further steps this Patch Tuesday by removing some of the functionality of Microsoft Equation Editor to prevent CVE-2017-11882 from being exploited.
Businesses can mitigate this attack in three main ways:
Ensuring Office installations and operating systems are kept patched and 100% up to date
Training end users on cybersecurity best practices and the danger of opening Office documents from unknown individuals. Consider sending a warning about this campaign and the email subject lines being used
Every February, Valentine’s day email scams are to be expected and this year has been no different. On Monday, a massive new phishing campaign was launched. The Necurs botnet was used to deliver millions upon millions of dating, romance and Valentine’s themed emails.
Dating and Valentine’s Day Email Scams Pose Problems for Businesses
Dating scams increased significantly in January and continued in February. You have probably seen the emails already in one of your inboxes.
The emails appear to have been sent by Russian women desperate to find love. Unsolicited emails from attractive women complete with suggestive pictures and messages claiming the recipient is particularly attractive are certain to be spam, yet the emails are effective. The FBI’s figures indicate around $230 million is lost to these scams alone each year. In 2016, the FBI received around 15,000 complaints about financial losses as a result of dating and romance scams.
There were two major peaks in spam email volume between January 15 and 17 and January 29 and February 2 when around 35 million dating spam messages were delivered via the Necurs botnet. Over 230 million messages were sent in a two-week period in January. The aim of the campaign is to obtain credit card details, payments to cover flights to bring the women over to the US, but in many cases the purpose is to fool the email recipient into downloading malware.
Cybercriminals use all manner of tactics to entice users to click. Another effective technique, highlighted by security awareness training firms KnowBe4 and PhishMe, is the use of eCards, especially on Valentine’s Day. Links are sent that appear to be from legitimate eCard sites that require users to click the link to view a Valentine’s day card from a secret admirer. The purpose is to deliver malware.
Valentine’s day email scams this year also include messages alerting the recipient about the failed delivery of flowers from Interflora and email attachments claiming to be delivery receipts.
It is the likelihood of these emails being opened that makes defending against them a major headache for businesses. One single click is all it takes for malware to be installed, and since many malware variants can rapidly spread laterally, one click could be all it takes to compromise an entire network.
The Winter Olympics Scams Continue
This month has also seen plenty of Winter Olympics phishing campaigns conducted. Cybercriminals have been taking advantage of interest in the games to get their emails opened. Malicious links are used to direct users to websites that claim to have up to date news on the events, the competitors, fake news, and the results of events.
The reality is these links direct users to phishing websites, exploit kits, and sites where malware is silently downloaded. With workers unable to watch the sports live at work, these malicious emails stand a high chance of being opened.
With Valentine’s day and the Winter Olympics, February has been a busy month for scammers and with the Pyeongchang Winter Olympics still in full flow, businesses need to be on high alert.
Fortunately, there is one technology in particular that can help businesses counter these email-based threats. An advanced spam filtering solution: The most effective defense against email-based attacks. An advanced spam filter such as SpamTitan blocks more than 99.9% of spam emails, 100% of known malware, and ensures that phishing and other malicious emails do not reach inboxes.
Last week news broke that government supercomputers in Russia had been turned into cryptocurrency miners, now comes news that many UK government websites have been infected with cryptocurrency mining code.
More than 4,200 Websites Infected with Cryptocurrency Mining Code
The latest attack affects government websites around the globe, with more than 4,200 websites turning visitors’ computers into cryptocurrency miners.
The attack involved a popular website plugin called Browsealoud. Browsealoud is used to convert written website content into audio for the blind and partially sighted. The browser plugin was compromised by hackers who altered the source code of the plugin to include cryptocurrency mining code. By altering the plugin, the malicious code runs every time a site user visits a webpage that offers the audio function using the Browsealoud plugin.
When a visitor arrived at such as webpage, the code ran and turned that user’s computer into a cryptocurrency miner, using the computer’s processing power to mine Monero. Mining is the term given to verifying cryptocurrency transfers. Mining requires a computer to solve a complex problem. Once that problem is solved, the miner is rewarded with a small payment. In this case, the individual(s) who altered the code.
Using one computer to mine cryptocurrency will only generate a small return. However, by hijacking a browser plugin on a website that is visited by many thousands of individuals, the potential returns are considerable. The processing power of millions of computers can be harnessed.
Browsealoud was developed by the British company Texthelp. According to its website, its plugin has been installed on 4,275 domains. In the United Kingdom, many government websites use the plugin, including the Financial Ombudsman Service, the Information Commissioner’s Office, the Student Loans Company, many National Health Service (NHS) websites, and local government websites including the .gov.uk sites used by Camden, Croydon, Manchester, and Newham to name but a few. Many federal and state government websites in the US have turned their visitors’ devices into cryptocurrency miners, and it is the same story in Australia, Ireland, Sweden, and beyond.
The Browsealoud plugin is understood to have been infected with cryptocurrency mining code at some point between 0300 and 1145 UTC on February 11, 2018. The code was only active for a few hours before the change was identified and Texthelp disabled the plugin.
The mining only took place while a visitor was on a webpage that used the Browsealoud plugin. As soon as the tab or browser was closed, the mining stopped. Visiting the website that had been infected with cryptocurrency mining code via the plugin would not result in a malware infection. The only noticeable effect for any visitors to the websites would have been a slowing down of their computers or the fan starting as their computer started going into overdrive.
This incident has however made it quite clear to government agencies that their websites are not secure and using third party plugins on their sites to improve services for website users introduces risk.
These supply-chain attacks exploit a trusted relationship between the website owner and a third-party software/plugin supplier and the benefits for cybercriminals are clear. All it takes is for one plugin to be hacked to have malicious code run on many thousands of websites, thus targeting millions of website visitors. In this case, the damage caused was minimal, but the attack could have been much worse. The goal on this occasion was to mine cryptocurrency. The attackers could easily have inserted much more malicious code and attempted to steal login credentials.
That means a new hash is required if the vendor does not include a version number in their updated code. However, it will ensure that attacks such as this, or worse attacks with much more malicious code, will be blocked.
Following a slew of cyber extortion attacks on schools, the FBI and the Department of Education’s Office of the Inspector General have issued a warning. Schools need to be alert to the threat of cyber extortion and must take steps to mitigate risk by addressing vulnerabilities, developing appropriate policies and procedures, and using technologies to secure their networks.
K12 schools and other educational institutions are an attractive target for cybercriminals. They hold large quantities of valuable data – The types of data that can be used to commit identity theft and tax fraud. Further, in education, security defenses are typically of a much lower standard than in other industries. Poor defenses and large volumes of valuable data mean cyberattacks are inevitable.
The warning comes after several cyber extortion attacks on schools by a group of international hackers known collectively as TheDarkOverlord. The hacking group has conducted numerous attacks on the healthcare industry the public school system since April 2016.
The modus operandi of the hacking group is to search for vulnerabilities that can be easily exploited to gain access to internal networks. Once network access is gained, sensitive data is identified and exfiltrated. A ransom demand is then issued along with the threat to publish the data if payment is not made. The hacking group does not make empty threats. Several organizations that have failed to pay have seen their data dumped online. Recent attacks have also included threats of violence against staff and students.
Access to networks is typically gained by exploiting vulnerabilities such as weak passwords, poor network security, unpatched software, and misconfigured databases and cloud storage services.
The FBI reports that the hacking group has conducted at least 69 cyber extortion attacks on schools, healthcare organizations, and businesses and has stolen more that 100 million records containing personally identifiable information. More than 200,000 of those records have been released online after ransom demands were ignored. More than 7,000 students have had their PII exposed by the hackers.
The escalation of the threats to include violence have caused panic and some schools have been temporarily closed as a result. Sensitive data has been released which has placed staff and students at risk of financial losses due to fraud. The FBI recommends not paying any ransom demand as it just encourages further criminal activity. What schools must do is take steps to mitigate risk and make it harder for their institution to be attacked. By doing so, cybercriminals are likely to continue their search for organizations that are easier to attack.
Ransomware and DDoS Attacks are Rife
TDO is not the only criminal group conducting cyber extortion attacks on schools, and these direct attacks are not the only way access to school networks is gained.
The past two years have seen a massive rise in the use of ransomware on schools. Ransomware attacks are often indiscriminate, taking advantage of vulnerabilities in human firewalls: A lack of security awareness of staff and students. These attacks commonly involve email, with malicious attachments and links used to deliver the ransomware payload.
Ransomware is malicious code that is used to search for stored files and encrypt them to prevent access. With files encrypted, organizations must either restore files from backups or pay the ransom demand to obtain the key to unlock the encryption. Since the code can also encrypt backup files, many organizations have had no alternative other than paying the ransom, since data loss is not an option.
Other cyber extortion attacks on schools do not involve data theft. DoS and DDoS attacks bombard servers with thousands or millions of requests preventing access and often damaging hardware. Cybercriminal gangs use mafia-style tactics to extort money, threatening to conduct DoS/DDoS attacks unless payment is made. Alternatively, they may conduct the attacks and demand payment to stop the attack.
The rise in cyber extortion attacks on schools means action must be taken to secure networks. A successful attack often results in educational institutions suffering major losses. The ransom payment is only a small part of the total cost. Removing ransomware, rebuilding systems, and protecting individuals whose sensitive data has been exposed can cost hundreds of thousands of dollars.
How to Protect Against Cyber Extortion Attacks on Schools
Schools and other educational institutions can develop policies and procedures and use technologies to deter cybercriminals and improve network and email security. By adhering to IT best practices and adopted a layered approach to security, it is possible to mount a robust defense and prevent cyber extortion attacks on schools.
Educational institutions should:
Implement strong passwords: Weak passwords can easily be cracked using brute force methods. Set strong passwords (Upper/lower case letters, numbers, and special characters or long 15+ digit passphrases) and use rate limiting to block access attempts after a set number of failures. Never reuse passwords for multiple accounts.
Patch promptly: Vulnerabilities in software and operating systems can easily be exploited to gain access to networks. Develop good patch management policies and ensure all software and operating systems are updated promptly.
Implement an advanced spam filter: Phishing and spam emails are commonly used to deliver ransomware and obtain login credentials. Do not rely on the spam filters of email service providers. Implement separate, advanced anti spam software or a cloud-based filtering service to block email-based threats and prevent them from reaching inboxes.
Provide security awareness training: Cybersecurity should be taught. Staff and students should be made aware of email and web-based threats and told how to identify malicious emails and potential web-based threats.
Implement a web filter: A web filter is necessary for CIPA compliance to protect students from harm caused by viewing obscene images online. A web filter is also an important cybersecurity defense that can block malware and ransomware and stop staff and students from visiting phishing websites.
Secure remote desktop/access services: Conduct audits to determine which devices have remote access enabled. If remote access is not necessary, ensure it is disabled. If the services cannot be disabled, ensure they are secured. Use Secure Sockets Layer (SSL) Transport Layer Security for server authentication, ensure sessions are encrypted, and use strong passwords. Whitelist access is strongly recommended to ensure only authorized devices can connect.
Use two-factor authentication: Use two-factor authentication on all accounts to prevent access if a password is used on an unfamiliar device.
Limit administrator accounts: Administrator accounts should be limited. When administrator access is not required, log out from those accounts and use an account with fewer privileges.
Segment your network: Segmenting the network can limit the damage caused when malware and ransomware is installed, preventing it from spreading across the entire network.
Scan for open ports and disable: Conduct a scan to identify all open ports and ensure those open, unused ports are disabled.
Monitor audit logs: Audit logs for all remote connection protocols, check logs to ensure all accounts were intentionally created, and audit access logs to check for unauthorized activity.
Backup all data: Good backup polices are essential for recovery from ransomware attacks: Adopt a 3-2-1 approach. Make three copies of backups, store them on at least two different media, and keep one copy off site. Backups should be on air-gapped devices (not connected to the Internet or network).
A new FedEx phishing scam has been detected that appears to be targeting universities and businesses. Spam emails with the subject line ‘FedEx Delivery Notification’ are sent to users that explain FedEx was unable to deliver a package. The email claims the package was over the allowable weight limit and did not qualify for free delivery.
The email recipients are informed that in order to collect the package, they must visit their local FedEx depot in person. The package will not be released unless the user presents a label to the dispatcher, which the user is required to print.
The sophisticated FedEx phishing scam involves no email attachments, only a link. However, the link does not appear to be a malicious site. The attackers are using Google Drive to distribute their malware.
This is an increasingly common tactic that abuses trust of Google. Since the website is genuine – drive.google.com – users are less likely to believe that they are being scammed. The hyperlink will direct the user to Google Drive and will trigger the download of a file called Lebal copy.exe. An executable file that if run, will install malware.
Many people know not to run executable files, although in this case the file is disguised as a PDF and has the PDF icon. If known file extensions are not configured to be displayed on the user’s computer – which is now common- they would not be aware that the file is not a PDF.
The latest scam was uncovered by researchers at Comodo, who identify the malware as a Trojan called TrojWare.Win32.Pony.IENG that steals cookies and credentials. It is capable of stealing information from FTP clients, attempts to obtain and access cryptocurrency wallets, and extracts a wide range of user data and transmits the information to its command and control server. The malware uses various tactics to avoid detection by anti-malware and anti-virus defences.
Universities and Businesses Fall for FedEx Phishing Scam
According to Comodo, so far there have been 23 businesses, several government employees, and five university employees that have fallen for the scam. Since those businesses were protected by anti-virus software that was able to block the malware they avoided infection, although many others will not be so fortunate.
Protecting against scams like this requires layered defenses and user vigilance. Spam filters should be used by businesses to detect and quarantine spam emails such as this. Links to Google Drive can be difficult to block, as Google Drive is a legitimate website. Antivirus and anti-malware defenses must therefore be in place to detect the malicious download.
Businesses should not forget the human element of the security chain. Security awareness training and phishing simulations can help users to detect a FedEx phishing scam such as this.
Netflix Users Targeted by Scammers
A new sophisticated Netflix scam has appeared in the past few days. The emails claim users will have their Netflix membership suspended due to a problem processing the most recent payment.
The email appears to have been sent from Netflix and includes all the appropriate branding, making the email look highly convincing. The subject line is ‘Suspension of your membership’.
The email says there was a problem validating the most recent payment, and a link is supplied in the email that requires the user to validate their payment and billing information.
Clicking the link directs the user to what appears to be the Netflix website where they are asked to go through a series of steps to validate their account. The validation process requires them to re-enter their payment card information. The failure to complete the step will result in the suspension of their Netflix account.
The website contains the correct branding and looks exactly like the legitimate site. The URL is different, but the website is HTTPS and has the green padlock. A casual glance at the URL may not reveal there is anything wrong with the site.
Spam filtering solutions such as SpamTitan can detect this type of scam, but users must exercise caution as not all phishing emails can be blocked.
Users should carefully check the URL of any site they visit to make sure it is legitimate before entering sensitive information. Links sent in emails should be checked by hovering the mouse arrow over the link to find out the true URL.
An email such as this should prompt the user to visit Netflix using their usual bookmark or by typing in the URL into their browser, rather than visiting any links in the email.
Phishing emails cost a North Carolina school district $314,000 to resolve and caused considerable disruption while the infection was removed.
The high cost of resolving the attack was due to a particularly nasty and difficult to remove malware variant called Emotet malware which had been installed on endpoints and servers after employees responded to phishing emails.
The Rockingham County School District was attacked in late November. Numerous employees of the school district received a phishing email in their inboxes which appeared to be an incorrect invoice from their anti-virus provider. The emails contained an attachment and asked users to open the file to confirm. Doing so triggered the infection process, that resulted in the Emotet virus being downloaded.
The purpose of the malware is to obtain banking credentials. To ensure the maximum number of credentials are stolen, the virus is able to spread to other users. It was the attempt to spread that saw the infection detected. Some employees of the school district discovered their Google email accounts had been disabled as a result of spamming, which prompted an investigation. Internet access through web browsers was also impacted, suggesting a widespread malware infection.
While a malware infection was confirmed, removing the virus was not an easy task. There is no anti-virus software program that can remove the virus and prevent infection. The school district was able to clean and reimage some infected devices, but they were subsequently reinfected.
Unable to resolve the malware infection internally, the school district was forced to bring in external security consultants. In total, approximately a dozen infected servers had to be rebuilt to remove the infection. The school district also had to cover the cost of reimaging 3,000 workstations. The recovery is expected to involve some 1,200 on-site hours by IT staff and the process is expected to take up to a month.
During that time, the school district has had limited access to computers and had to loan around 200 Windows devices for key personnel. In order to cover the cost of the phishing attack, the school district took $314,000 in funds from its coffers.
“We feel like the $314,000 will get us back to where we were before we had the virus,” said school district Superintendent Rodney Shotwell.
The high cost of the phishing attack and the disruption caused shows just how important it is to deploy an advanced anti spam software solution to prevent malicious emails from reaching inboxes, and the importance of providing security awareness training to all employees to help them identify potential phishing attacks.
What industries are the most susceptible to phishing scams? What industries must do more to prevent phishing attacks on their employees?
Recent research shows organizations that fail to implement technological defenses to block phishing emails and do not provide phishing awareness training to their employees are likely to suffer costly data breaches.
This year’s cost of a data breach study conducted by the Ponemon Institute suggests the average cost of mitigating a data breach is $3.62 million, while the FBI’s figures show that between 2013 and 2016, more than $1.6 billion was lost to phishing scams – Approximately $500 million a year. Phishing attacks on organizations have also been increasing year on year.
Unfortunately, while public awareness of the threat from phishing has improved considerably in recent years, an alarming number of employees continue to fall for phishing scams. A recent survey conducted by the phishing awareness training company Knowbe4 showed an astonishing 27% of employees clicked on a potentially malicious link or opened an email attachment sent via its phishing simulation tests. In some industry sectors, more than a third of employees failed the phishing simulations.
The Industries Most Susceptible to Phishing
Many studies produce questionable results due to a low sample size. However, the Knowbe4 study used data from 11,000 organizations and 6 million users. The results of the study therefore paint an accurate picture of just how susceptible employees are to phishing attacks.
Phishing simulations were run prior to the provision of security awareness training to obtain a baseline of the susceptibility of employees to phishing attacks. The results showed the industries most susceptible to phishing were insurance, manufacturing, retail, and non-profits. In the 1-249 employee category, 35.46% of insurance employees failed phishing tests, and 33.32% of employees failed the tests in the 250-999 employee category – The highest level of susceptibility of any industry sector in both categories.
Manufacturing was second worse in the 1-249 employee category with a failure rate of 33.21% followed by not-for-profits on 32.63%. In the 250-999 employee category, manufacturing (31.06) and business services (31.01%) were second and third.
The 1000+ employee category showed much reduced phishing susceptibility rates, ranging from business services on 19.40% to not-for-profits on 30.97%. Even the best performing industry sector saw almost 2 out of 10 employees fail phishing tests.
90 days after implementing a phishing awareness program, susceptibility to phishing was dramatically reduced. In the insurance sector, susceptibility rates fell from 35% and 33% in the small and medium sized business categories to 13% and 16%. A massive improvement. Overall, after a year – once phishing awareness training programs had matured – the overall susceptibility rates fell to a level of around 1% to 2%, with the highest percentages at the 5% level.
The survey shows just how important it is to provide ongoing training for the workforce to improve security awareness and the clear benefits of doing so.
It will never be possible to reduce phishing susceptibility to zero, therefore organizations should ensure that phishing emails are not delivered inboxes in the first place, and for that, an advanced anti spam software solution such as SpamTitan is required.
The exponential growth in the price of cryptocurrencies has been accompanied by similar growth in email campaigns spreading cryptocurrency mining malware. There has also been a big rise in new mining malware variants, with three new malware variants detected in the past week. Conservative estimates suggest one malware variant has already been installed on at least 15 million systems, although the true figure could well be closer to 30 million.
The data comes from the cybersecurity firm Palo Alto Networks, which performed an analysis of the URLs used in the campaign using Bitly telemetry. It is difficult to determine how many systems have been affected since Bitly is not the only URL shortening service being used in the campaign. AdFly is also in use, which suggests the number of infected systems could well be twice as high.
The malicious links for this campaign are being sent in spam email. Clicking the links will direct the user to a malicious website containing executable files that install the Monero mining application XMRig using VBS scripts. The popularity of Monero mining is due to the lower processor demands than cryptocurrencies such as Bitcoin. Monero mining can take place on less powerful computers such as those typically at home. In addition to spam email campaigns, the malicious executable files are being loaded to popular file sharing websites
Cryptocurrency mining malware does not pose such a big threat to organizations as other forms of malware and ransomware, but there are implications for businesses. The malware does require a considerable amount of processing power, so there will be an impact on performance on infected machines. Infection will see applications slow considerably, and that will have an impact on productivity.
Campaigns are also being conducted that target businesses. The aim is to installing cryptocurrency mining malware on business servers. These attacks are not email-based, instead vulnerabilities are identified and exploited to install the malware, with Apache Struts (CVE-2017-5638) and DotNetNuke (CVE-2017-9822) vulnerabilities commonly exploited.
Preventing Infection with Cryptocurrency Mining Malware
Businesses can prevent cryptocurrency mining malware from being installed on their servers by ensuring all applications are patched and kept up to date. The patch to fix the Apache Struts vulnerability was released in September 2017, yet many businesses have not applied the patch. The DNN vulnerability has also been patched.
The risk of infections on employee and home computers requires antivirus and antimalware software and an advanced spam filter to prevent malicious messages from reaching inboxes. Businesses should also be training their staff how to recognize malicious emails. Training programs and phishing email simulations have been shown to help reduce susceptibility to email-based attacks by up to 95%.
The past few months have also seen a rise in cryptocurrency mining malware infections via unsecured WiFi networks, with cybercriminals performing man-in-the-middle attacks that hack the WiFi sessions of any user connected to one of the rogue WiFi access points. Unsecured public WiFi hotspots should be avoided, or VPNs used.
In this post we explain two of the most important strategies to adopt to block phishing and ransomware attacks.
Ensure Malicious Messages Do Not Reach Inboxes
Last year, Netwrix released a report based on a survey that showed 100% of government IT workers believed employees were the biggest threat to security. While those figures are the highest of many such surveys, the common theme throughout all of the research is employees are the most likely cause of a data breach.
One of the biggest areas of weakness is email-based attacks. Research conducted by the Friedrich Alexander University in Germany suggests half of users click links in emails from unknown senders. Those links often lead employees to phishing and malware-laced websites. With such high click rates, it is no surprise that so many IT workers believe employees are the weakest link in their security defenses.
Stopping employees from taking risky actions is difficult, so organizations must do all they can to ensure malicious emails are not delivered to inboxes. Only then, can IT workers be sure that employees will not click links or open dangerous email attachments.
TitanHQ is a leading provider of spam filtering solutions for enterprises. SpamTitan ensures the vast majority of spam and malicious emails are identified and quarantined and are not delivered to inboxes. SpamTitan has been independently tested and shown to block 99.97% of spam emails, ensuring end users are protected. But what can organizations do to protect their employees from the 0.03% of emails that are delivered to inboxes?
There is No Silver Bullet That Will Block Phishing and Ransomware Threats 100% of the Time
No business can no survive without email and unfortunately, no spam filtering solution can block 100% of all spam emails, 100% of the time. At least not without also blocking many genuine messages. Organizations cannot rely on a spam filter to block phishing and ransomware threats. It is just one important layer of security. Several other layers are required.
Anti-virus and anti-malware solutions are essential for detecting malicious software, but these signature-based security controls are proving less and less effective as years go by. For instance, the solutions are not particularly good at detecting fileless malware.
Most businesses further reduce risk by implementing endpoint protection systems that can detect anomalies and unnatural behavior on endpoints, indicative of an intrusion, malware activity, or ransomware scanning for files and making changes.
However, AV software and endpoint detection systems only detect phishing and ransomware attacks when they are occurring. If you want to block phishing and ransomware attacks, the most effective solution is a human firewall.
IT departments can blame employees for being the weakest link when it comes to security, but if employees are not trained and shown how to recognize malicious emails, they will remain the biggest security threat to an organization.
The Human Firewall – The Best Defense Against Phishing, Malware, and Ransomware Emails
A firewall is the first line of defense, and anti spam software will help to keep inboxes free from malicious messages. The rear guard is made up of your employees. To ensure you have a strong defensive backline, you must provide security awareness training. Many employees do not know that they are taking big risks that could compromise the network. It is up to organizations to ensure that those risks are explained.
Most malware and ransomware attacks involve at least some user interaction: The clicking of a link, the opening of a malicious document, or the enabling of a macro. Employees must be told this is how malware is installed and how access to email accounts and networks is gained. By training the workforce to be more security aware, employees can be turned into a formidable last line of defense.
Security Awareness Training Should Be Continuous
While it was once possible to provide annual security training and be reasonably confident that employees would be able to recognize malicious emails, that is no longer the case. Email-based cyberattacks are now far more sophisticated, and cybercriminals are investing considerably more time in developing highly convincing campaigns. Cybercriminals’ tactics are constantly changing. Training programs must reflect that.
To develop a strong human firewall, training should be ongoing. An annual classroom-based training session should be accompanied by regular CBT training sessions, provided in bite-sized chunks. Cybersecurity should be kept fresh in the mind with monthly email bulletins, as well as ad hoc alerts about new threats.
Research conducted by several security awareness training companies shows, training is very effective. PhishMe, Wombat Security Technologies, and Knowbe4 all suggest that with regular training it is possible to reduce susceptibility to email-based attacks by up to 95%.
Test the Effectiveness of Security Awareness Training with Phishing Simulations
You can backup all your data to ensure you can recover files in the event of a disaster, but if your backups are never tested you can never be sure file recovery is possible.
Similarly, providing security awareness training to employees will not guarantee you have created a strong human firewall. Your firewall must be tested. By sending phishing simulations to your workforce you can find out just how effective your training has been. You can identify weak links – employees that have not grasped the concept of phishing and email security and those individuals can be scheduled additional training. Phishing simulation exercises also help to reinforce training. When a test is failed, it can be turned into a learning opportunity, which helps to improve knowledge retention.
Implement technological solutions to block phishing and ransomware attacks and train your employees and test them on all manner of email-based attacks. When the real deal arrives in an inbox they will be prepared and deal with it appropriately. Fail to block emails or provide high quality training, and your company is likely to have to deal with a costly, and potentially disastrous, email-based attack.
Tax season is open season for cybercriminals and phishers, who increase their efforts to obtain personal information and Social Security numbers in the run up to – and during – tax season. Until April, we can expect many W2 phishing attacks. Make sure you are prepared and do not fall for a scam.
Anatomy of a W2 Phishing Attack
The most common method of stealing the information needed to file fraudulent tax returns is phishing. Phishing emails are sent in the millions to individuals in an effort to obtain their sensitive information. Individuals must be on high alert for malicious emails during tax season, but it is businesses that are most likely to be targeted.
Payroll employees have access to the W2 forms of the entire workforce. If a single worker can be convinced to email the data, the attacker can file thousands of fraudulent tax returns in the names of employees.
The way cybercriminals get payroll staff to part with sensitive data is by impersonating the CEO or CFO in what is referred to as a Business Email Compromise Scam – otherwise known as a BEC attack or CEO fraud.
The most successful attacks require access to the CEO or CFO’s email account to be gained. That means the CEO or CFO must first be targeted with a spear phishing email and lured into parting with his/her login credentials. Once access to the email account is gained, the impostor can craft an email and send it to a select group of individuals in the company: Payroll and accounts department employees.
The company is researched, individuals likely to have access to W2 forms are identified, and emails are sent. A request is made to attach the W2 forms of all employees who worked for the company in the past year, or for a specific group of employees. A series of emails may be sent, rather than asking for the information straight away.
Since the attacker has access to the CEO’s or CFO’s email account, they can delete sent emails and replies before they are seen by the account holder.
An alternative way of conducting BEC attacks is to spoof an email address. The CFO or CEO is identified from social media sites or LinkedIn, the email address is obtained or guessed based on the format used by the company, and the email is made to appear as if it has come from that email account. An alternative is for the attacker to purchase a similar domain to that used by the company, with two transposed letters for instance. Enough to fool an inattentive worker.
Oftentimes, W2 phishing attacks are not detected until days or weeks after the W2 forms have been sent, by which times IRS tax refund checks have been received and cashed.
How to Defend Against W2 Phishing Attacks
There are several methods that can be used to block W2 phishing attacks. A software or cloud-based anti-spam service should be used to block attacks that come from outside the company. Configured correctly, the spam filter should block spoofed emails and emails sent from similar domains to that used by the company. However, a spam filter will not block emails that come from the CFO or CEOs account.
Multi-factor authentication should be set up on all email accounts to help prevent the first phish that gives the attacker access to a C-suite email address. W2 phishing attacks using spoofed email addresses are much easier to identify and block.
It is therefore important to raise awareness of the threat of W2 phishing attacks with accounts and payroll staff, and anyone else with access to W2 forms. Training can greatly reduce susceptibility to W2 phishing attacks. Training should also be provided to the C-suite, not just employees.
The number of staff who have access to W2 forms should be restricted as far as is possible. Policies should also be introduced that require any request for W2 data to be verified. At a minimum, a request for the data should be checked by a supervisor. Ideally, the request should be confirmed face to face with the sender of the email, or with a quick phone call. The scammers rely on this check not taking place.
The insurance, telecoms, and financial service sectors are being targeted by malicious actors spreading Zyklon malware. A large-scale spam email campaign has been detected that leverages three separate Microsoft Office vulnerabilities to download the malicious payload.
Zyklon malware is not a new threat. The malware variant was first detected at the start of 2016, but it stopped being detected soon after and was not extensively used until the start of 2017.
Zyklon malware is a backdoor with a wide range of malicious functions. The malware acts as a password harvester, keylogger, and data scraper, obtaining sensitive information and stealing credentials for further attacks. The malware can also be used to conduct DoS attacks and mine cryptocurrency.
The latest variant of Zyklon malware can download and run various plugins and additional malware variants. It can identify, decrypt, and steal serial keys and license numbers from more than 200 software packages and can also hijack Bitcoin addresses. All told, this is a powerful and particularly nasty and damaging malware variant that is best avoided.
While the latest campaign uses spam email, the malware is not included as an attachment. A zip file is attached to the email that contains a Word document. If the document is extracted, opened, and the embedded OLE object executed, it will trigger the download of a PowerShell script, using one of three Microsoft Office vulnerabilities.
The first vulnerability is CVE-2017-8759: A Microsoft NET vulnerability that was patched by Microsoft in October.
The second ‘vulnerability’ is Dynamic Data Exchange (DDE) – a protocol part of Office that allows data to be shared through shared memory. This protocol is leveraged to deliver a dropper that will download the malware payload. This vulnerability has not been patched, although Microsoft has released guidance on how to disable the feature to prevent exploitation by hackers.
The third vulnerability is far older. CVE-2017-11882 is a remote code execution flaw in Microsoft Equation Editor that has been around for 17 years. The flaw was only recently identified and patched by Microsoft in November.
The second stage of infection – The PowerShell script – serves as a dropper for the Zyklon malware payload.
According to the FireEye researchers who identified the campaign, the malware can remain undetected by hiding communications with its C2 using the Tor network. “The Zyklon executable contains another encrypted file in its .Net resource section named tor. This file is decrypted and injected into an instance of InstallUtiil.exe, and functions as a Tor anonymizer.”
Campaigns such as this highlight the importance of applying patches promptly. Two of the vulnerabilities were patched in the fall of 2017, yet many organizations have yet to apply the patches and remain vulnerable. If patches are not applied, it will only be a matter of time before vulnerabilities are exploited.
FireEye researchers have warned that while the campaign is currently only targeting three industry sectors, it is probable that the campaign will be widened to target other industry sectors in the near future.
The advice is to implement an advanced cloud-based anti-spam service such as SpamTitan to identify and quarantine malicious emails, and ensure that operating systems and software is kept up to date.
More than 60 apps have now been removed from Google Play Store that were laced with AdultSwine Malware – A malware variant that displays pornographic adverts on users’ devices. Many of the apps that contained the malware were aimed at children, including Drawing Lessons Lego Star Wars, Mcqueen Car Racing Game, and Spinner Toy for Slither. The apps had been downloaded by between 3.5 and 7 million users before they were identified and removed.
While the malicious apps have been removed, users who have already downloaded the infected apps onto their devices must uninstall the apps to remove the malware. Simply deleting the apps from the Play Store only prevents more users from being infected. Google has said that it will display warnings on Android phones that have the malicious apps installed to alert users to the malware infection. It will be up to users to then uninstall those apps to remove the AdultSwine malware infection.

Malicious Activities of AdultSwine Malware
AdultSwine malware, and the apps that infect users, were identified and analyzed by security researchers at CheckPoint. The researchers note that once downloaded onto a device, the malware sends information about the user to its command and control server and performs three malicious activities: Displaying advertisements, signing up users to premium services, and installing scareware to fool victims into paying for security software that is not necessary. Information is also stolen from the infected device which can potentially be used for a variety of malicious purposes.
The advertisements are displayed when users are playing games or browsing the Internet, with the adverts coming from legitimate ad networks and the AdultSwine library. The AdultSwine malware library includes extreme adverts containing hardcore pornographic images. Those images appear on screen without warning.
The scareware claims the victim’s device has been infected with a virus that requires the download of an anti-malware app from the Google Play Store, although the virus removal tool is a fake app. Users are told that their phone will be rendered unusable if the app is not downloaded, with a countdown timer used to add urgency.
Registering for premium services requires the user to supply further information, which is done through pop-up phishing adverts. The user is told they have won a prize, but that they must answer four questions to claim their prize. The information they supply is used to register for premium services.
Preventing Infection of Mobile Devices
Generally, users can reduce the risk of a malware infection by only downloading apps from official app stores, although this latest malware campaign has shown that even official stores can be compromised and have malicious apps uploaded.
Google does scan all apps for malware, but new forms of malware can be sneaked into Google Play Store on occasion. Google has announced that from the end of January it will be rolling out a new service called Google Play Protect that is capable of scanning previously downloaded apps to ensure they are still safe to use.
Google recommends only downloading apps for children that have been verified by Google as being ‘Designed for Families’. Those apps may contain adverts, but they have been vetted and strict rules apply covering the advertisements that can be displayed.
It is also important to install some form of anti-malware solution – from a reputable and well-known company – that will scan downloaded content and apps for malware.
It has been pretty difficult to avoid the news of Meltdown and Spectre – Two vulnerabilities recently discovered that could potentially be exploited to gain access to sensitive information on PCs, Macs, servers, and smartphones. Meltdown and Spectre affect virtually all devices that contain CPUs, which amounts to billions of devices worldwide.
What are Meltdown and Spectre?
Meltdown and Spectre are two separate vulnerabilities affecting CPUs – central processing units. The chips that power a wide range of electronic devices. The flaws make devices vulnerable to side-channel attacks, in which it is possible to extract information from instructions that have been run on CPUs, using the CPU cache as a side channel.
There are three types of attacks, two for Spectre and one for Meltdown. Spectre Variant 1 – tracked as CVE-2017-5753- is a bounds check bypass, while Spectre variant 2 – tracked as CVE-2017-5715 – is a branch target injection. Variant 3, termed Meltdown – tracked as CVE-2017-5754 – is a rogue data cache load, memory access permission check that is performed after kernel memory read.
The less technical explanation is the attacks leverage the prediction capabilities of the CPU. The CPU will predict processes, load them to an easily accessible, fast sector of the memory to save time and ensure fast performance. Spectre allows data to be read from the memory, but also for information to be loaded into the memory and read that would otherwise not be possible.
Meltdown also reads information from the memory, stealing information from memory used by the kernel that would not normally be possible.
What Devices are Affected by Meltdown and Spectre?
US-CERT has warned that the following vendors have been affected by Meltdown and Spectre: AMD, Apple, Arm, Google, Intel, Linux Kernel, Microsoft, and Mozilla. Apple has said that virtually all of its Macs, iPhones, and iPads are affected. PCs and laptops with Intel, Arm, and AMD chips are affected by Spectre, as are Android smartphones. while Meltdown affects desktops, laptops, and servers with Intel chips. Since servers are affected, that has major implications for cloud service providers.
How Serious are Meltdown and Spectre?
How serious are Meltdown and Spectre? Serious enough for the Intel chief executive officer, Brian Krzanich, to sell $25 million of his shares in the company prior to the announcement of the flaws, although he maintains there was no impropriety and the sale of the shares was unrelated to the announcement of the flaws a little over a month later.
For users of virtually all devices that contain CPUs, the flaws are certainly serious. They could potentially be exploited by malicious actors to gain access to highly sensitive data stored in the memory, which can include passwords and credit card data.
What makes these flaws especially serious is the number of devices that are affected – billions of devices. Since one of the flaws affects the hardware itself, which cannot be easily corrected without a redesign of the chips, resolving the problem will take a considerable amount of time. Some security experts have predicted it could take decades before the flaws are totally eradicated.
At present, it would appear that the flaws have not been exploited in the wild, although now the news has broken, there will certainly be no shortage of individuals attempting to exploit the flaws. Whether they are able to do so remains to be seen.
What Can You do to Prevent Meltdown and Spectre Attacks?
As is the case when any vulnerability is identified, protecting against Meltdown and Spectre requires patches to be applied. All software should be updated to the latest versions, including operating systems, software packages, and browsers. Keeping your systems 100% up to date is the best protection against these and other attacks.
Some third-party antivirus software will prevent Windows patches from being installed, so before Windows can be updated, antivirus must be updated. Ensure that your AV program is kept up to date, and if you have automatic updates configured for Windows, as soon as your system is ready for the update it will be installed.
Chrome and Firefox have already been updated, Microsoft will be rolling out a patch for Windows 10 on Thursday, and over the next few days, updates will be released for Windows 7 and 8. Apple has already updated MacOS version 10.13.2, with earlier versions due to receive an update soon.
Google has already issued updates for Android phones, although only Google devices have so far been updated, with other manufactures due to roll out the updates shortly. Google has already updates its Cloud Platform, and Amazon Web Services has also reportedly been updated. Linux updates will also be issued shortly.
Fixes for Meltdown are easier to implement, while Spectre will be harder as true mitigations would require major changes to the way the chips work. It is unlikely, certainly in the short term, for Intel to attempt that. Instead, mitigations will focus on how programs interact with the CPUs. As US-CERT has warned, “[The] Underlying vulnerability is caused by CPU architecture design choices. Fully removing the vulnerability requires replacing vulnerable CPU hardware,” although that advice is no longer detailed in its updated vulnerability warning.
Applying patches will help to keep computers protected, but that may come at a cost. For example, the fix for the Meltdown vulnerability changes the way the computer works, which means the processor will have to work harder as it has to repeatedly access information from the memory – tasks that would otherwise not normally need to be performed.
That will undoubtedly have an impact on the performance of the machine. How much of a dip in performance can be expected? Some experts predict the changes could slow computers down by as much as 30%, which would certainly be noticed at times when processor activity is particularly high.
A recently discovered Forever 21 POS malware attack has seen customers’ credit card data compromised. While malware attacks on retail POS systems are now commonplace, in the case of the Forever 21 POS malware attack, the security breach stands out due to the length of time malware was present on its systems. Attackers first gained access to its POS system seven months before the infection was discovered.
The Forever 21 POS malware infections were first identified in October, when a third-party linked credit card fraud to customers who had previously visited Forever 21 stores. The potential malware infections were investigated and a third-party cybersecurity firm was called in to assist.
Forever 21 first made the announcement about a data breach in November, although the investigation has been ongoing and now new details about the attack have been released.
The investigation has revealed the attack was extensive and affected many POS devices used in its U.S. stores. The Forever 21 POS malware attack started on April 3, 2017, with further devices compromised over the following 7 months until action was taken to secure its systems on November 18, 2017. Forever 21 reports that some POS devices in its stores were only compromised for a few days, others for a few weeks, while some were compromised for the entire timeframe.
In response to the increased threat of cyberattacks on retailers, Forever 21 started using encryption technology on its payment processing systems in 2015; however, the investigation revealed the encryption technology was not always active.
While the encryption technology was active, the attackers would have been prevented from obtaining the credit card details of its customers, although the information could be stolen at times when the encryption technology was turned off.
Further, some devices that were compromised by the malware maintained logs of completed credit card transactions. When the encryption technology was not active, details of completed transactions were stored in the logs and could therefore be read by the attackers. Since those logs contained details of transactions prior to the malware infections, it is possible that customers who visited affected Forever 21 stores prior to April 3, 2017 may also have had their credit card details stolen.
Each store uses multiple POS devices to take payments from consumers, and in most cases only one device per store was compromised. The attackers concentrated their efforts on stores where POS devices did not have encryption enabled. Further, the attackers main aim appeared to be to find and infect devices that maintained logs of transactions.
On most POS devices, the attackers searched for track data read from payment cards, and in most cases, while the number, expiry date and CVV code was obtained, the name of the card holder was not.
The investigation into the Forever 21 POS malware attack is ongoing, and at present it is unclear exactly how many of the company’s 700+ stores have been affected, how many devices were infected, and how many customers have had their credit and debit card details stolen. However, it is fair to assume that an attack of this duration will have affected many thousands of customers.
The type of malware used in the attack is not known, and no reports have been released that indicate how the attackers gained access to its systems. It is not yet known if stores outside the US have been affected.
2017 has been a bad year for data breaches, but what were the worst data breaches of 2017? We have compiled a list of the largest and most serious cyberattacks that came to light this year.
The Worst Data Breaches of 2017
Equifax – 143 Million Records
The Equifax data breach was discovered in September and ranks first in our list of the worst data breaches of 2017, not just for the size of the breach, but also due to the nature of data stolen by the attackers. Equifax reports that the breach impacted as many as 143 million consumers – That’s 44% of the population of the United States.
The data stolen in the attack including highly sensitive information – the types of data cybercriminals seek in order to commit identity theft and fraud. Social Security numbers and driver’s license numbers were stolen along with names, addresses, dates of birth, and credit card numbers. The breach was the result of an unpatched software vulnerability.
Deep Root Analytics – 198 Million Records
The data breach at Deep Root Analytics was massive, involving almost 200 million records. Deep Root Analytics is a marketing firm that was contracted by the Republican National Convention to gather political information on U.S voters.
The data were stored in an Amazon AWS S3 bucket that could be accessed without the need for a password for two weeks before the lack of protection was discovered. During that time, voter records could be accessed, including names, addresses, dates of birth, and phone numbers.
Uber – 57 Million Records
The Uber data breach may not have been the most severe in terms of the types of data exposed, but it certainly ranks as one of the worst data breaches of 2017, affecting some 57 million riders and drivers.
What really makes this one of the worst breaches of 2017 is the discovery that Uber attempted to keep the breach quiet. Uber paid the attacker $100,000 to keep quiet and not publish the data, which included names, addresses, email addresses, and in some cases, driver’s license numbers. The breach occurred in October 2016, but it was not disclosed for more than a year.
Verizon – 14 Million Records
As with many other data breaches in 2017, this security breach was due to an unsecured Amazon AWS S3 bucket that was controlled by NICE systems – A partner of Verizon. It is unclear whether Verizon customer data was stolen, but the records of 14 million customers were exposed. Those records included names, PIN numbers, and phone numbers in the form of logs from Verizon customers that had called its customer service department. Potentially, the information could be used to access customers’ accounts. The data were stored in an unprotected Amazon AWS S3 bucket
Dun & Bradstreet – 33.7 Million Records
The data analytics firm Dun & Bradstreet created a marketing database containing 52 GB of data, including 33.7 million email addresses and contact information. While Dun & Bradstreet maintains its systems were not compromised, one of the companies that the database was sold to certainly was. The database contained the records of millions of employees of major companies including Wal-Mart and CVS Health, as well as the U.S Postal Service and the Department of Defense.
America’s JobLink – 4.8 Million Records
A misconfigured application was exploited by a hacker to gain access to the records of 4.8 million individuals. The data were maintained by America’s JobLink – a firm that connects employers and job seekers
The breach was detected in March 2017, although an analysis revealed the code error was introduced in October 2016. The hacker exploited the vulnerability in February and had access to the data for a month.
The breach was particularly bad as it involved names, dates of birth and Social Security numbers, placing the breach victims at a high risk of identity theft and fraud. It is unclear whether the hacker managed to steal all 4.8 million records.
Deloitte – 350+ records
In the list of the largest data breaches of 2017, the Deloitte breach would come in very close to the bottom; however, in terms of the potential severity of the breach it ranks near the top. An estimated 350 clients were impacted when a hacker gained access to Deloitte’s email server and email conversations between the firm and its clients. Those clients included government departments – including Homeland Security and the Department of Defense – the National Institutes of Health, FIFA, and the U.S Postal Service.
The breach was discovered this year, although the hackers reportedly had access to its systems for several months. The email server was breached using an admin account, with the breach preventable had two-factor authentication been used.
River City Media – 1.4 Billion Records
A massive illegal spam operation run by River City Media was uncovered this year by security researchers, who discovered more than 1.4 billion records had been left exposed online. An analysis of the data showed there were 393 million unique email addresses in the database, along with names, IP addresses, and real addresses.
The investigation into River City Media revealed the group was sending as many as a billion emails a day, and was masquerading as a legitimate marketing company. The files were exposed due to poor RSync backup practices, which ensured a disaster would not result in data loss, but the firm inadvertently left its data exposed online.
Onliner Spambot – 711 Million Records
Another massive data breach to affect spammers involved the operator of the onliner spambot, which harvested email addresses to send spam emails. A database of some 711 million email addresses was left exposed online after the server on which the data were stored had been left unprotected. It is unknown how many people discovered the database and are now using it to plague those 711 million individuals with email more spam email. The breach was largely limited to email addresses, but in terms of size, it certainly ranks as one of the worst data breaches of 2017.
Every December, a list of terrible passwords is published by SplashData, and this year the list of the worst passwords of 2017 contains the same horrors as years gone by. Passwords that not only would take a hacker next to no time to guess, but in many cases, could be cracked at the first attempt.
The list of the worst passwords of 2017 is compiled from databases of leaked and stolen passwords that have been published online throughout 2017. This year, SplashData compiled its list from more than 5 million leaked passwords.
The minimum password length on many websites has now been increased to eight characters; however, it is still possible to use passwords of six characters in many places. This year, the worst password is six characters long and is the extremely unimaginative: 123456. A password so easy to guess, it is barely worth setting a password at all.
In second place is an eight-character password, which is similarly not worth using at all: password. In third place is 12345678. Those three passwords retained the same positions as last year.
Each year, the same passwords appear on the list, with slight fluctuations in their positions in the list. However, there are some new entries this year. The rebooting of the Star Wars saga has spurred many people to choose Star Wars related passwords, with starwars featuring in 16th position on the list.
An interesting entry makes it into 25th place – trustno1. Good advice, but even with the addition of a number, it is still a poor password choice. At first glance, number 24 in the list appears to be reasonable, but qazwsx is the first six characters on the left-hand side of the keyboard.
Using the passwords letmein, passw0rd, admin, master, and whatever, are all equally bad. All of those words make the top 25 in the list of the worst passwords of 2017.
Top 25 Worst Passwords of 2017
The list of the worst passwords of 2017 reveals many people are extremely unimaginative when choosing a password to secure their email, social media, and online accounts.
SplashData estimates 3% of people have used the worst password on the list, while 10% have used one of the first 25 passwords to “secure” at least one online account.
Most people know that strings of consecutive numbers are bad, as is any variation of the word password, but changing to a dictionary word or a pop culture reference is just as bad, as Morgan Slain, CEO of SplashData, Inc., explained, “Hackers are using common terms from pop culture and sports to break into accounts online because they know many people are using those easy-to-remember words.”
That means using football (or any other sport) or starwars will not prevent a hacker from gaining access to an account for very long.
What Makes a Bad Password?
Brute force attacks, those where repeated attempts are made to guess passwords, does not involve a hacker sitting at a computer typing bad passwords until the correct one is guessed. Those attacks are performed by bots, and it doesn’t take long for a bot to guess a poor password.
Without rate limiting – setting a maximum number of failed attempts before access is temporarily blocked – to slow down the process, the bots can cycle through the list of the worst passwords of 2017 quickly, followed by those used in other years and other dictionary words.
Hackers also know the tricks that people use to keep passwords easy to remember, while meeting the strong password requirements set by IT departments, such as adding an explanation mark to the end of an easy to remember word or replacing certain letters with their numerical equivalent: An A with a 4, or an O with a zero for instance.
What Makes a Good Password?
A good password should contain upper and lowercase letters, numbers, and special characters, and should preferably be a random string of 10 or more characters. That of course makes passwords very difficult to remember. Writing the password down so you don’t forget it is also a very bad idea, as is reusing passwords on multiple sites and recycling old passwords.
In 2017, NIST revised its advice on choosing passwords as its research showed that forcing people to choose upper and lower-case passwords and special characters did not always ensure people chose strong passwords. Instead, they get around the technology by simply changing the first letter to a capital letter and adding a special character and number to the end, for instance.
Instead, NIST recommended using a passphrase rather than a password. A phrase that only you would know.
A list of four or five unrelated words would work well. Dogforkliftmonkeyhousecar would be a strong password phrase to use (other than the fact it has now been published online). It would be difficult to crack but easy to remember with a mnemonic.
To keep your accounts secure, make sure you choose strong and complex passwords, ideally long passwords of at least 15 characters. However, remembering the 20 or so unique passwords you are likely to need will still be hard.
The solution is to use a password manager, and to secure that account with a strong hard to guess password. Then only one complex password must be remembered.
Digimine malware is a new threat that was first identified from a campaign in South Korea; however, the attacks have now gone global.
Ransomware is still a popular tool that allows cybercriminals to earn a quick payout, but raised awareness of the threat means more companies are taking precautions. Ransomware defenses are being improved and frequent backups are made to ensure files can be recovered without paying the ransom. Not only is it now much harder to infect systems with ransomware, rapid detection means large-scale attacks on companies are prevented. It’s harder to get a big payday and the ability to restore files from backups mean fewer organizations are paying up.
The surge in popularity of cryptocurrency, and its meteoric rise in value, have presented cybercriminals with another lucrative opportunity. Rather than spread ransomware, they are developing and distributing cryptocurrency miners. By infecting a computer with a cryptocurrency miner, attackers do not need to rely on a victim paying a ransom.
Rather than locking devices and encrypting files, malware is installed that starts mining (creating) the cryptocurrency Monero, an alternative to Bitcoin. Mining cryptocurrency is the verification of cryptocurrency transactions for digital exchanges, which involves using computers to solve complex numeric problems. For verifying transactions, cryptocurrency miners are rewarded with coins, but cryptocurrency mining requires a great deal of processing power. To make it profitable, it must be performed on an industrial scale.
The processing power of hundreds of thousands of devices would make the operation highly profitable for cybercriminals, a fact that has certainly not been lost on the creators of Digimine malware.
Infection with Digimine malware will see the victim’s device slowed, as its processing power is being taken up mining Monero. However, that is not all. The campaign spreading this malware variant works via Facebook Messenger, and infection can see the victim’s contacts targeted, and could potentially result in the victim’s Facebook account being hijacked.
The Digimine malware campaign is being spread through the Desktop version of Facebook Messenger, via Google Chrome rather than the mobile app. Once a victim is infected, if their Facebook account is set to login automatically, the malware will send links to the victim’s contact list. Clicking those links will result in a download of the malware, the generation of more messages to contacts and more infections, building up an army of hijacked devices for mining Monero.
Infections were first identified in South Korea; however, they have now spread throughout east and south-east Asia, and beyond to Vietnam, Thailand, Philippines, Azerbaijan, Ukraine, and Venezuela, according to Trend Micro.
A similar campaign has also been detected by FortiGuard Labs. That campaign is being conducted by the actors behind the ransomware VenusLocker, who have similarly switched to Monero mining malware. That campaign also started in South Korea and is spreading rapidly. Rather than use Facebook Messenger, the VenusLocker gang is using phishing emails.
Phishing emails for this campaign contain infected email attachments that download the miner. One of the emails claims the victim’s credentials have been accidentally exposed in a data breach, with the attachment containing details of the attack and instructions to follow to mitigate risk.
These attacks appear to mark a new trend and as ransomware defenses continue to improve, it is likely that even more gangs will change tactics and switch to cryptocurrency mining.
A Q3 malware threat report from McAfee charts the continued rise in malware threats throughout the year. Malware variants have now reached an all time high, with the volume of threats having risen each quarter in 2017.
In 2016, there were high levels of malware in Q1, rising slightly in Q2 before tailing off in Q3 and A4. That trend has not been seen this year. The malware threat report shows Q1 figures were higher than the previous two quarters, with a massive rise in Q3 and a continued increase in Q3. Malware threats rose 10% quarter over quarter, rising to a quarterly total of 57.6 million new samples of malware: The highest quarterly total detected by McAfee. That averages out at a new malware sample detected every quarter of a second!
The ransomware epidemic has also got worse in Q3, with new ransomware variants increasing by 36% last quarter, fueled by a sharp increase in Android screen lockers. In total, new mobile malware variants increased by 60% in Q3.
In its Q3 Malware Threat Report, McAfee noted that attackers were continuing to rely on spam email to distribute malware, with the Gamut botnet the most prevalent spamming botnet in Q3, closely followed by the Necurs botnet. The latter was used to spread ransomware variants such as Locky. Mac malware rose by 7% in Q3, and macro malware increased by 8%.
Vulnerabilities in software and operating systems were also extensively exploited, even though patches to address those vulnerabilities were released promptly.
McAfee notes that employees and organizations are making it far too easy for attackers. Employees are responding to phishing emails, are visiting malicious links and are opening attachments and enabling the content. Employers are no better. Patches are released, yet they are not being applied promptly, opening the door to attackers. In many cases, patches have still not been applied several months after they have been released.
One of the most commonly exploited vulnerabilities in Q3, 2017 was CVE-2017-0199 which affected WordPad and Microsoft Office. An exploit for the vulnerability was made available through GitHub, making remote code execution attacks easy; provided employees could be convinced to open specially crafted files. Many employees fell for the scam emails.
The McAfee Q3 Malware Threat Report highlighted several continuing malware trends, including the increase in the use of fileless malware. PowerShell malware increased by 119% in Q3 alone.
Q3 saw a new Locky variant released – Lukitus. Lukitus was spread via spam email, with more than 23 million messages delivered in the first 24 hours since its release. That, combined with other new ransomware threats, have contributed to a 44% increase in ransomware samples in the past 12 months.
Q3 also saw the release of a new variant of the Trickbot Trojan, which incorporated the EternalBlue exploit that was also used in the WannaCry and NotPetya attacks.
While no industry is immune to attack, it is the healthcare and public sectors that are taking the brunt of the attacks, accounting for 40% of all reported security incidents in Q3. In the United States, healthcare was the most commonly attacked industry.
The extensive use of spam and phishing emails to spread malware highlights the importance of using an advanced spam filtering solution such as SpamTitan, especially considering how employees are still struggling to identify malicious emails. Blocking these threats and preventing malicious messages from being delivered will help organizations prevent costly data breaches.
The high level of infections that occurred as a result of exploited vulnerabilities also shows how important it is to apply patches promptly. McAfee notes that many of the exploited vulnerabilities in Q3 were patched as early as January. If patches are not applied promptly, they will be exploited by cybercriminals to install malware.
