Our spam news section provides up to date news on the latest threats that are likely to hit the inboxes of your employees. Cybercriminals are constantly changing tactics with new spam email campaigns, different social engineering techniques and new methods of installing malware and ransomware. By keeping up to date on the latest spam news, organizations can take timely action to mitigate risk.
In that regard, a spam filtering solution is essential. All it takes is for one employee to click on a malicious link or open an infected email attachment for an entire network to be compromised. A spam filter will check all incoming email messages and search for common spam signatures in addition to checking senders’ email accounts against blacklists of known spammers. Email attachments will be checked for virus signatures and hyperlinks compared to blacklists of known malicious domains.
Armed with the latest spam news, information security teams can send email alerts to their employees warning of pertinent threats that they need to be aware of.
This section also includes news on industry-specific attacks, in particular those that are being used to target the healthcare, education, financial services, legal and hospitality sectors.
The threat from phishing is ever present and phishing remains the leading cause of data breaches. All it takes is for one employee to fall for a phishing email for threat actors to gain the foothold they need to conduct more extensive attacks on the organization. But how common is phishing? In this post we provide some key 2020 phishing statistics to raise awareness of the threat and highlight the need for businesses to rethink their current phishing defenses.
2020 Phishing Statistics
Phishing is the easiest way for cybercriminals to gain access to sensitive data and distribute malware. Little skill or effort is required to conduct a successful phishing campaign and steal credentials or infect users with malware. The latest figures show that in 2020, 22% of reported data breaches started with a phishing email and some of the largest data breaches in history have started with a phishing attack, including the 78.8 million record data breach at the health insurer Anthem Inc., and the massive Home Depot data breach in 2014 that saw the email addresses of 53 million individuals stolen.
Phishing can be conducted over the phone, via SMS, social media networks, or instant messaging platforms, but email is most commonly used. Around 96% of all phishing attacks occur via email. Successful phishing attacks result in the loss of data, theft of credentials, or the installation of malware and ransomware. The cost of resolving the incidents and resultant data breaches is substantial. The 2020 Cost of a Data Breach Report by the Ponemon Institute/IBM Security revealed the average cost of a data breach is around $150 per compromised record with a total cost of $3.86 million per breach. A single spear phishing attack costs around $1.6 million to resolve.
Employees may believe they are able to spot phishing emails, but data from security awareness training companies show that in many cases, that confidence is misplaced. One study in 2020 revealed that 30% of end users opened phishing emails, 12% of users clicked a malicious link or opened the attachment in the email, and one in 8 users then shared sensitive data on phishing websites. Bear in mind that 78% of users claimed that they know they shouldn’t open email attachments from unknown senders or click links in unsolicited emails.
The 2020 phishing statistics show phishing and spear phishing are still incredibly common and that phishing attacks often succeed. Another study revealed 85% of companies have fallen victim to a phishing attack at least once. Phishing websites are constantly being created and used in these scams. Once a URL is confirmed as malicious and added to a blacklist, it has often already been abandoned by the threat actors. In 2020, around 1.5 million new phishing URLs were identified every month.
2020 has seem a massive increase in ransomware attacks. While manual ransomware attacks often see networks compromised by exploiting vulnerabilities in firewalls, VPNs, RDP, and networking equipment, ransomware is also delivered via email. Since 2016, the number of phishing emails containing ransomware has increased by more than 97%.
How to Detect and Block Phishing Threats
Tackling phishing and preventing successful attacks requires a defense in depth approach. An advanced spam filtering solution is a must to prevent phishing emails from reaching inboxes. Companies that use Office 365 often rely on the protections provided as standard with their licenses, but studies have shown that the basic level of protection provided by Microsoft’s Exchange Online Protection (EOP) is insufficient and average at best and phishing emails are often not detected. A third-party, solution is recommended to layer on top of Office 365 – One that incorporates machine learning to identify never before seen phishing threats. The solution should use email authentication protocols such as DMARC, DKIM, and SPF to identify and block email impersonation attacks and outbound scanning to identify compromised mailboxes.
End user training is also important. In the event of a phishing email arriving in an inbox, employees should be trained to identify it as such and be conditioned into reporting the threat to their IT team to ensure action can be taken to remove all instances of the threat from the email system. Web filters are also important for blocking the web-based component of phishing attacks and preventing employees from visiting phishing URLs. Multi-factor authentication on email accounts is also essential. In the event of credentials being stolen, MFA will help to ensure that the credentials cannot be used to access email accounts.
Phishers are constantly changing their tactics to fool employees into clicking on links and disclosing their credentials. During the pandemic, many scammers switched from their tried and tested campaigns using standard business-themed lures such as fake invoices, purchase orders, and shipping notices to COVID-19 themed lures. These lures were topical and took advantage of people craving information about the coronavirus and COVID-19.
Phishers Use Fake Internal Memos About Changes to HR Work from Home Policies
Now a new phishing campaign has emerged that takes advantage of the changed business practices due to COVID-19. Many employees are still working remotely, even though their employers have started reopening their offices. During the pandemic, employees have got used to receiving regular internal company memos and updates.
The new phishing campaign spoofs the company’s HR department and appears to be an automated internal company email, similar to the messages employees are used to receiving. The emails claim to have voicemail attachments, which will also be familiar to many remote workers. The HTML attachments are personalized with the recipient’s name to add credibility to the message.
If the file attachment is opened, the user will be presented with a link they are required to click to receive the company information. In one campaign, this was a SharePoint link, although other cloud services could similarly be used. The link directs the user to SharePoint and provides an update on the company’s remote working policy. After reading the message, the worker is required to click a link that directs them to the actual phishing page where sensitive information is collected.
This campaign is very realistic. The fake remote working policy is well written and plausible and states that if employees wish to continue working from home after the pandemic, they are required to complete an HR form to provide notice in writing. The SharePoint-hosted Excel form where the user is directed is also plausible, but in addition to the request to continue to work from home, the user is required to supply their email credentials.
Phishing Campaign Offers Government Financial Aid to COVID-Affected Workers
A separate phishing campaign has been identified that is also linked to the pandemic, spoofing government agencies and offering pandemic-related financial assistance for individuals prevented from working due to COVID-19 restrictions or have otherwise been adversely affected. This campaign has targeted U.S. citizens, although similar campaigns could be conducted targeting individuals in other countries.
In this campaign, which has the subject message “US government to give citizens emergency financial aid,” the message states that the government begun issuing payments of cash compensation in October 2020. The message states that payment is only provided to USA residents and the maximum payout is $5,800.
A link is supplied in the email that the user is required to click to make a claim, which the email states will be reviewed by a support representative who will send a personal response within 24 hours. The link directs the user to a domain that spoofs the U.S. government. The user is required to enter their name and date of birth, followed by their address, contact information, Social Security number, and driver’s license number on a second form.
Phishing is the Most Common Type of Cybercrime
A recent Clario/Demos survey confirmed that phishing and email attacks are the most common types of cybercrime reported in both the United States and the United Kingdom.
The pandemic has made it easier for phishing attacks to succeed. Phishers are taking advantage of the uncertainty about changes to new ways of working caused by the pandemic, people working home alone without such a high level of support, and vulnerabilities that have been introduced as a result of the change to a fully remote workforce.
Businesses can better protect their employees by using cloud-based email and web filtering solutions. These solutions work in tandem to block the email and web-based component of phishing attacks and malware distribution campaigns. A cloud-based email filtering solution will filter out the majority of malicious messages and will keep inboxes free of threats. A web filter will prevent end users from visiting malicious links, downloading malicious attachments, or visiting malicious websites either through work-related or non-work-related Internet activity when working from the office or remotely.
TitanHQ has developed two easy to use, easy to implement, and highly effective email and web security solutions for protecting office-based and remote workers from the full range of web and email threats, including previously seen phishing emails and zero-minute attacks and new malware threats.

Banking Trojans have long posed a threat to businesses, but one in particular has stood head and shoulders above the rest in 2020: The Emotet Trojan.
Emotet: The Biggest Malware Threat in 2020
The Emotet Trojan first appeared in 2014 and was initially a banking Trojan, which was used to steal sensitive data such as bank account information from browsers when the user logs into their bank account. The Emotet Trojan has since been developed and it has now evolved into a much bigger threat.
Emotet is now far more effective at spreading to other devices, using a worm like element to infect other devices on the network as well as hijacking the user’s email account and using it to send copies of itself to victims’ contacts. Infected devices are added to the Emotet botnet, and have been used in attacks on other organizations. The operators of Emotet have now joined forces with other cybercriminal operations and are using their malware to deliver other Trojans such as TrickBot and QakBot, which in turn are used to deliver ransomware.
Data from HP Inc. revealed Emotet infections increased by 1,200% from Q2 to Q3, showing the extent to which activity has increased recently. Data from Check point show Emotet is the biggest malware threat, accounting for 12% of all infections in October 2020. TrickBot, which is delivered by Emotet, is the second biggest threat, accounting for 4% of infections.
Emotet and TrickBot are Driving the Increase in Ransomware Infections
The Emotet and TrickBot Trojans are driving the increase in ransomware infections globally, especially attacks on healthcare organizations. The healthcare industry in the United States is being targeted by ransomware gangs due to the increased chance of the ransom being paid. In many cases, the recent ransomware attacks have been made possible due to previous Emotet an TrickBot infections.
Unfortunately, due to the efficient way that Emotet spreads, removing the malware can be problematic. It is probable that more than one device has been infected, and when the Trojan is removed from one device, it is often reinfected by other infected devices on the network.
The best way of preventing attacks is stopping the Emotet emails from reaching inboxes and making sure that employees are trained how to recognize phishing emails.
How SpamTitan Can Protect Your Organization
SpamTitan use a wide range of different techniques to identify phishing emails that are used to deliver malware such as Emotet. These measures provide layered protection, so should one check fail to identify the threat, several others are in place to provide protection.
SpamTitan uses dual antivirus engines to identify previously seen malware variants and sandboxing to identify new (zero day) malware threats. Suspicious email attachments are sent to the sandbox where they are subjected to in depth analysis to identify malicious actions such as command and control center callbacks.
SpamTitan uses Sender Policy Framework (SPF) and DMARC to block spoofing and email impersonation attacks, which are used to convince employees to open attachments and click malicious links. SpamTitan also includes outbound scanning, which detects devices that have potentially been infected and prevents messages from spreading Emotet internally and to business contacts.
There are many cybersecurity solutions that can provide protection against malware, but finding one that is easy to use, effective, and reasonably priced can be a challenge.
SpamTitan ticks all of those boxes. It is the most and best ranked email security solution on Capterra, GetApp and Software Advice, has achieved a rating of 4.9 out of 5 on Google reviews, and is listed in the top three in the email security gateway, MSP email security, and email security for Office 365 categories.

The threat of phishing is ever present, especially for the healthcare industry which is often targeted by phishers due to the high value of healthcare data and compromised email accounts. Phishing attacks are having a major impact on healthcare providers in the United States, which are reporting record numbers of successful phishing attacks. The industry is also plagued by ransomware attacks, with many of the attacks having their roots in a successful phishing attack. One that delivers a ransomware downloader such as the Emotet and TrickBot Trojans, for example.
A recent survey conducted by HIMSS on U.S. healthcare cybersecurity professionals has confirmed the extent to which phishing attacks are succeeding. The survey, which was conducted between March and September 2020, revealed phishing to be the leading cause of cybersecurity incidents at healthcare organizations in the past year, being cited as the cause of 57% of incidents.
One interesting fact to emerge from the survey is the lack of appropriate protections against phishing and other email attacks. While it is reassuring that 91% of surveyed organizations have implemented antivirus and antimalware solutions, it is extremely concerning that 9% appear to have not. Only 89% said they had implemented firewalls to prevent cybersecurity incidents.
Then there is multi-factor authentication. Multifactor authentication will do nothing to stop phishing emails from being delivered, but it is highly effective at preventing stolen credentials from being used to remotely access email accounts. Microsoft suggested in a Summer 2020 blog post that multifactor authentication will stop 99.9% of attempts to use stolen credential to access accounts, yet multifactor authentication had only been implemented by 64% of healthcare organizations.
That does represent a considerable improvement from 2015 when the survey was last conducted, when just 37% had implemented MFA, but it shows there is still considerable for improvement, especially in an industry that suffers more than its fair share of phishing attacks.
In the data breach reports that are required for compliance with the Health Insurance Portability and Accountability Act (HIPAA) Rules, which healthcare organizations in the U.S are required to comply with, it is common for breached organizations to state they are implementing MFA after experiencing a breach, when MFA could have prevented that costly breach from occurring in the first place. The HIMSS survey revealed 75% of organizations augment security after suffering a cyberattack.
These cyberattacks not only take up valuable resources and disrupt busines operations, but they can also have a negative impact on patient care. 28% of respondents said cyberattacks disrupted IT operations, 27% said they disrupted business operations, and 20% said they resulted in monetary losses. 61% of respondents said the attacks had an impact on non-emergency clinical care and 28% said the attacks had disrupted emergency care, with 17% saying they had resulted in patient harm. The latter figure could be underestimated, as many organizations do not have the mechanisms in place to determine whether patient safety has been affected.
The volume of phishing attacks that are succeeding cannot be attributed to a single factor, but what is clear is there needs to be greater investment in cybersecurity to prevent these attacks from succeeding. An effective email security solution should be top of the list – One that can block phishing emails and malware attacks. Training on cybersecurity must be provided to employees for HIPAA compliance, but training should be provided regularly, not just once a year to meet compliance requirements. Implementation of multifactor authentication is also an essential anti-phishing measure.
One area of phishing protection that is often overlooked is a web filter. A web filter blocks the web-based component of phishing attacks, preventing employees from accessing webpages hosting phishing forms. With the sophisticated nature of today’s phishing attacks, and the realistic fake login pages used to capture credentials, this anti-phishing measure is also important.
Many hospitals and physician practices have limited budgets for cybersecurity, so it is important to not only implement effective anti-phishing and anti-malware solutions, but to get effective solutions at a reasonable price. That is an area where TitanHQ excels.
TitanHQ can provide cost-effective cloud-based anti-phishing and anti-malware solutions to protect against the email- and web-based components of cyberattacks and both of these solutions are provided at a very reasonable cost, with flexible payment options.
Further, these solutions have been designed to be easy to use and require no technical skill to set up and maintain. The ease of use, effectiveness, and low price are part of the reason why the solutions are ranked so highly by users, achieving the best rankings on Capterra, GetApp and Software Advice.

The Emotet Trojan is one of the main malware threats currently used to attack businesses. The Trojan is primarily distributed using spam emails, using a variety of lures to convince users to install the Trojan.
The spam emails are generated by the Emotet botnet – an army of zombie devices infected with the Emotet Trojan. The Trojan hijacks the victim’s email account and uses it to send copies of itself to the victim’s business contacts using the email addresses in victims’ address books.
Emotet emails tend to have a business theme, since it is business users that are targeted by the Emotet actors. Campaigns often use tried and tested phishing lures such as fake invoices, purchase orders, shipping notices, and resumes, with the messages often containing limited text and an email attachments that the recipient is required to open to view further information.
Word documents are often used – although not exclusively – with malicious macros which install the Emotet Trojan on the victim’s device. In order for the macros to run, the user is required to ‘Enable Content’ when they open the email attachment.
Users are instructed in the documents to enable content using a variety of tricks, oftentimes the documents state that the Word document has been created on an IoS or mobile device, and content needs to be enabled to allow the content to be viewed or that the contents of the document have been protected and will not be displayed unless content is enabled.
Earlier this month, a new lure was used by the Emotet actors. Spam emails were sent explaining a Windows update needed to be installed to upgrade apps on the device, which were preventing Microsoft Word from displaying the document contents. Users were instructed to Enable Editing – thus disabling Protected View – and then Enable Content – which allowed the macro to run.
The Emotet Trojan does not simply add devices to a botnet and use them to conduct further phishing attacks. One of the main uses of Emotet is to download other malware variants onto infected devices. The operators of the Emotet botnet are paid by other threat actors to distribute their malware payloads, such as the TrickBot Trojan and QBot malware.
The TrickBot Trojan was initially a banking Trojan that first appeared in 2016, but the modular malware has been regularly updated over the past few year to add a host of new functions. TrickBot still acts as a banking Trojan, but is also a stealthy information stealer and malware downloader, as is QBot malware.
As with Emotet, once the operators of these Trojans have achieved their aims, they deliver a secondary malware payload. TrickBot has been used extensively to deliver Ryuk ransomware, one of the biggest ransomware threats currently in use. QBot has teamed up with another threat group and delivers Conti ransomware. From a single phishing email, a victim could therefore receive Emotet, TrickBot/QBot, and then suffer a ransomware attack.
It is therefore essential for businesses to implement an effective spam filtering solution to block the initial malicious emails at source and prevent them from being delivered to their employee’s inboxes. It is also important to provide security awareness training to employees to help them identify malicious messages such as phishing emails in case a threat is not blocked and reaches employees’ inboxes.
Organizations that rely on the default anti-spam defenses that are provided with Office 365 licenses should consider implementing an additional spam filtering solution to improve protection against Emotet and other malware and phishing campaigns. Phishing emails often slip past Office 365 defenses and are delivered to inboxes. With a powerful, advanced spam filtering solution such as SpamTitan layered on top of Office 365 anti-spam protections, users will be better protected.

A product demonstration can be arranged, your questions will be answered, and assistance will be provided to help set you up for a free trial to evaluate the solution in your own environment.
The TrickBot Trojan, one of the biggest malware threats to appear in recent years, has had its backend infrastructure taken down by a coalition of tech firms.
TrickBot started life in 2016 as a banking Trojan used to target Windows devices but the malware has received many updates over the years and has had many new modules added to give it a much wider range of capabilities. TrickBot targets hundreds of different banks and also steals credentials and Bitcoin wallets. In recent years, the operators have teamed up with several different criminal organizations and have used the Trojan to deliver keyloggers, cryptominers, information stealers and ransomware variants such as Ryuk and Conti. TrickBot can now perform a huge range of malicious actions via many different plugins and in January and February 2020 was targeting more than 600 websites via a webinject module, most of which being financial institutions.
The Trojan achieves persistence on infected devices and adds them to a botnet, which has grown into one of the largest in operation. The operators of the Trojan are also known to use the EternalBlue exploit to move around infected networks and spread the Trojan to other devices on the network. This can make removal of the Trojan difficult, as once it is removed from a device, other infected devices on the network simply reinfect it when it is reconnected.
TrickBot is primarily spread via phishing emails via malicious macros, but other malware-as-a-service operations also deliver TrickBot, such as Emotet. TrickBot typically used lures aimed at business users, such as shipment receipts, receipt reminders, required declarations, delivery notifications, and other logistics themes using Word and Excel attachments and Java Network Launch Protocol (.jnlp) attachments, as well as malicious hyperlinks embedded in emails. In 2020, a large-scale campaign was conducted using coronavirus and COVID-19 themed lures, one of which spoofed humanitarian groups and claimed to offer free COVID-19 tests.
Those emails were sent by a diverse range of compromised email accounts and marketing platforms, with the threat group also using domains with their own mail servers to distribute the malware. There has been growing concern that the botnet could also be used in campaigns to disrupt the upcoming November 3, 2020 U.S. presidential election.
TrickBot is stealthy and uses a variety of mechanisms to evade detection by security solutions, including password protected zip files, delayed downloads of the Trojan when macros are run, heavily obfuscated loaders, encryption of configuration files, and a complex command and control infrastructure. The latter has now been untangled and its backend infrastructure has been taken down.
Several tech firms including Microsoft, ESET, Black Lotus Labs, and NTT have been working together for months to try to disrupt the TrickBot operation. More than 125,000 samples of the TrickBot Trojan were analyzed along with over 40,000 configuration files used by various TrickBot modules. After several months of painstaking work, the command and control servers used by the botnet were identified and its network infrastructure was mapped. Armed with the IP addresses, Microsoft obtained a court order and seized control of the infrastructure of servers used to distribute and communicate with the malware and its various modules. The IP addresses associated with the malware have now been disabled.
When the takedown occurred, more than 1 million devices had been infected with the malware and were part of its botnet. The takedown is great news, as one more malware threat – and a major one at that – has been taken out of action, at least temporarily. Efforts are now underway by ISPs to contact victims to ensure the Trojan is removed from their systems.
Businesses are constantly targeted by cybercriminals and phishing one of the easiest ways that they can gain a foothold in corporate networks. An email is sent to an employee with a lure to entice them to click an embedded hyperlink and visit a website. When they arrive on the site, they are presented with a login prompt and must enter their credentials. The login prompt is indistinguishable from the real thing, but the domain on which the login prompt appears is controlled by the attacker. Any information entered on the website is captured.
End user training will go a long way to keeping your business protected against phishing attacks. Phishers target people using a variety of “social engineering” tactics to get them to take a specific action, which could be visiting a website and downloading malware, giving up their login credentials, or sending a wire transfer to the criminal’s bank account. By conditioning employees to perform checks and to stop and think before taking any action suggested in an email, you will greatly improve resilience to phishing attacks.
Many employees will say that they can identify a phishing email and will never be fooled, but the number of successful phishing attacks that are occurring every day suggests there are gaps in knowledge and even the most tech-savvy individuals can be fooled.
To illustrate this point, consider the SANS Institute. If you have never heard of the SANS Institute, it is one of the world’s leading computer and information security training and certification organizations, including anti-phishing training.
In August 2020, the SANS Institute announced that one of its employees had fallen for a phishing scam and disclosed their login credentials. The attacker used those credentials to access the account and set up a mail forwarder that sent a copy of every email to the attacker’s email account. 513 emails, some of which contained sensitive information on SANS members, were forwarded to the account before the attack was detected. The emails contained the personally identifiable information of 28,000 SANS members. The SANS Institute decided to use this attack as a training tool and will be providing details of how it succeeded to help others prevent similar attacks.
This incident shows that even the most highly trained individuals can fall for a phishing email. Had training not been provided, instead of one compromised email account there could have been many.
Phishers are constantly changing tactics and developing new scams to fool people and technological anti-phishing solutions. The key to phishing attack prevention is to implement a range of defenses to block attacks. Any one of those measures may fail to detect a phishing email on occasion, but others will be in place to provide protection. This defense-in depth approach is essential given the sophistication of phishing attacks and the volume of messages now being sent.
In addition to regular end user training and phishing simulation emails to harden the human element of your defenses, you need an advanced spam filter. If you use Office 365 you will already have a basic level of protection provided through Microsoft’s basic spam filter, Exchange Online Protection (EOP), but this should be augmented with a third-party solution such as SpamTitan to block more threats. EOP blocks spam, known malware, and many phishing emails, but SpamTitan will greatly improve protection against more sophisticated phishing attacks and zero-day malware.
You should also consider implementing a web filter to block the web-based component of phishing attacks. When an employee attempts to visit a malicious website that is used to steal credentials and other sensitive information, a web filter can prevent that website from being accessed.
With a spam filter, web filter, and end user training, you will be well protected, but you should also implement 2-factor authentication. If credentials are stolen, 2-factor authentication can prevent those credentials from being used by the attacker to gain access to the account.

Our team of experienced engineers will be happy to help you set up SpamTitan email security and the WebTitan web filter on a free trial so you can see for yourself how effective both are at blocking phishing attacks and other cybersecurity threats.
Several SBA loan phishing scams identified in recent weeks that impersonate the U.S. Small Business Administration in order to obtain personally identifiable information and login credentials for fraudulent purposes.
Due to the hardships suffered by businesses due to the COVID-19 pandemic, the SBA’s Office of Disaster Assistance is offering loans and grants to small businesses to help them weather the storm.
Hundreds of millions of dollars has been made available by the U.S government under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) to help struggling individuals and companies during the pandemic. Cybercriminals have been quick to develop campaigns to fraudulently obtain those funds, raid bank accounts, steal sensitive information, and distribute malware and ransomware.
Several phishing campaigns have been launched since April 2020 targeting businesses that are considering or have already applied for loans under the SBA’s Economic Injury Disaster Loan Program.
Phishing emails have been sent encouraging small businesses to apply for a loan. One such campaign confirms that the business is eligible for a loan and the loan has been pre-approved. The purpose of the scam is to obtain business information that allows the scammers to apply for a loan on behalf of the business and pocket the funds.
Another scam impersonates the SBA and claims an application for a loan is complete and payment will be made once supporting documents have been received. The emails include an attached form that must be completed and uploaded to the SBA website. The email attachment appears to be a .img file but has a hidden double extension and is actually a .exe executable. Double clicking and running the file will see GuLoader malware installed, which is a downloader that can deliver a range of different malicious payloads.
The same email address used for that campaign was used in a different attack that included a PDF form that requested bank account information and other sensitive data, which needed to be completed and uploaded to a spoofed SBA website.
In the past few days, yet another SBA loan phishing scam has come to light. Phishing emails were sent to Federal Executive Branch, and state, local, tribal, and territorial government agencies. The phishing scam relates to an SBA application for a loan with the subject line “SBA Application – Review and Proceed.” The emails links to a cleverly spoofed SBA web page that indistinguishable from the genuine login page apart from the URL that attempts to steal credentials. The scam prompted the DHS’ Cybersecurity and Infrastructure Security Agency (CISA) to issue an emergency alert warning of the scam.
These SBA loan phishing scams use a variety of lures and have multiple aims, but they can be avoided by following good cybersecurity best practices.
First and foremost, you should have an advanced spam filtering solution in place such as SpamTitan. SpamTitan checks email headers and message content for the signs of spam, phishing and scams and uses DMARC and sender policy framework (SPF) to identify and block email impersonation attacks.
Dual antivirus engines detect 100% of known malware and sandboxing is used to subject attachments to deep analysis to identify malicious code and malware that has not been seen before. Machine learning technology is also used to identify new phishing scams, along with multiple threat intelligence feeds to identify known phishing scams.
Prior to opening any downloaded document or file it should be scanned using antivirus software that has up to date virus definitions. Check the properties of files to make sure they are what they claim to be and do not have a double extension.
Care should be taken opening any email or email attachment, even emails that are expected. Steps should be taken to verify the legitimacy of any request received via email, especially one that requires the provision of personally identifiable information or requests bank account and other highly sensitive information.
Emails and websites may look legitimate and have SBA logos, but that does not guarantee they are genuine. Always carefully check the sender of the email – Genuine SBA accounts end with sba.gov. The display name can easily be spoofed so click reply and carefully check the email address is correct. Care should be taken when visiting any website linked in an email. Check the full URL of any website to make sure it is the legitimate domain.
CISA also recommends monitoring users’ web browsing habits and restricting access to potentially malicious websites. The easiest way to do this is by using a web filtering solution such as WebTitan. WebTitan allows businesses to monitor Internet activity in real-time, send automatic alerts, block downloads of certain file types, and carefully control the types of website that can be accessed by employees.

A new phishing campaign has been detected that uses Google Cloud Services to fool victims into giving up their Office 365 credentials. The new campaign is part of a growing trend of disguising phishing attacks using legitimate cloud services.
The phishing attack starts like any other with an email containing a hyperlink that the recipient is requested to click. If the user clicks the link in the email, they are directed to Google Drive where a PDF file has been uploaded. When the file is opened, users are asked to click a hyperlink in the document, which appears to be an invitation to access a file hosted on SharePoint Online.
The PDF file asks the victim to click the link to sign in with their Office 365 ID. Clicking the link will direct the user to a landing page hosted using Google’s storage.googleapis.com. When the user arrives on the landing page, they are presented with an Office 365 login prompt that looks exactly like the real thing. After entering their credentials, they will be directed to a legitimate PDF whitepaper that has been obtained from a well-respected global consulting firm.
The campaign has been designed to make it appear that the victim is simply being directed to a PDF file that has been shared via Sharepoint, and the actual PDF file is displayed after the victim has divulged their credentials. It is therefore likely that the victim will not realize that their Office 365 credentials have been phished. The only sign that this is a scam is the source code on the phishing page, which even tech-savvy individuals would be unlikely to check.
This campaign was identified by researchers at Check Point, but it is just one of many similar campaigns to have been identified over the past few months. Since these domains are legitimate and have valid SSL certificates, they are difficult to detect as malicious. This campaign abused Google Cloud Services, but several other campaigns have been detected using the likes of IBM Cloud, Microsoft Azure and others to add legitimacy to the campaigns.
This campaign highlights the importance of providing security awareness training to the workforce and warning employees about the risks of clicking links in unsolicited emails, even those that link to genuine domains. An advanced email security solution should also be implemented to block malicious emails and ensure the majority of malicious messages are not delivered to inboxes. That is an area where TitanHQ can help.
Emotet was the most prolific malware botnet of 2018 and 2019, but the botnet fell silent on February 7, 2020 but it has now sprung back to life and is being used to distribute Trojan malware. The botnet returned with a malicious spam campaign on July 17 of at least 30,000 emails, mostly targeting organizations in the United States and United Kingdom. The scale of the campaign has now grown to around 250,000 emails a day with the campaign now global.
The Emotet botnet is a network of computers infected with Emotet malware and there are estimated to be around half a million infected Windows computers under the control of the botnet operators. Those infected devices are contacted through the attackers’ command and control (C2) servers and are sent instructions to send out spam emails spreading Emotet malware.
Once the malware is downloaded, the infected computer is added to the botnet and is used to send spam emails. Emotet infections can also spread laterally within an organization. When investigations are launched following the detection of Emotet, it is common for other computers to be discovered to be infected with the malware.
What makes Emotet particularly dangerous is the operators of the botnet pair up with other threat groups and deliver other malware variants. Emotet has been used to distribute a range of malware variants since its creation in 2014, but recently the malware payload of choice was the TrickBot Trojan. TrickBot is a banking trojan cum information stealer that also serves as a malware downloader. In addition to stealing sensitive data, the operators of TrickBot pair up with other malware developers, notably the developers of Ryuk ransomware. Once TrickBot has stolen information, the baton is passed over to Ryuk, which will also steal data before encrypting files on network. The new Emotet campaign started by distributing the TrickBot Trojan, although the payload has since switched to the QakBot banking Trojan. QakBot also delivers ransomware as a secondary payload, with Prolock often used in the past.
Emotet emails use a variety of lures to get recipients to click links to malicious websites or open infected email attachments. Emotet targets businesses, so the lures used are business related, such as fake shipping notices, invoices, purchase orders, receipts, and job applications. The emails are often personalized, and the threat actors known to hijack email threads and send responses with malicious documents added.
An Emotet infection is serious and should be treated with the same urgency as a ransomware attack. Prompt action may allow Emotet to be removed before a secondary payload is delivered.
Fortunately, Emotet malware is delivered via email so that gives businesses an opportunity to prevent infections. By deploying an advanced spam filter such as SpamTitan that has sandboxing to subject email attachments to deep analysis, these malicious emails can be identified and quarantined. Coupled with other email security measures such as end user training, businesses can mount a robust defense and block infections.
The return of Emotet was inevitable, and while the resumption of activity is bad news, there is some good news. A vigilante hacker has started sabotaging Emotet operations by targeting a weak link in their infrastructure. Emotet malware is downloaded from the internet from a range of hacked WordPress sites. The vigilante has found that the temporary stores of Emotet can be easily hacked as they tend to all use the same password. After guessing that password, the Emotet payload has been replaced with a variety of animated GIFs and has disrupted operations, reducing infections to around a quarter of their normal levels. That said, the Emotet gang is attempting to regain control of its web shells and infections with Emotet are still growing.
A recent survey by Capterra on British SMEs has revealed 30% have fallen victim to a phishing attack during the COVID-19 lockdown. Just under half of the phishing emails received (45%) were related to coronavirus or COVID-19.
COVID-19 phishing emails increased significantly during the first quarter of 2020 as the coronavirus spread around the world. Since the virus was unknown to science, scientists have been working tirelessly to learn about the virus, the disease it causes, how the virus is spread, and what can be done to prevent infection. The public has been craving information as soon as it is available, which creates the perfect environment for phishing attacks. People want information and threat actors are more than happy to offer to provide it.
The Capterra survey highlights the extent to which these campaigns are succeeding. Employees are receiving phishing emails and being fooled by the social engineering tactics the scammers have adopted. The high success rate has seen many threat actors temporarily abandon their tried and tested phishing campaigns that they were running before the SARS-CoV-2 outbreak, and have repurposed their campaigns to take advantage of the public’s thirst for knowledge about the virus. In the first quarter of 2020, KnowBe4 reported a 600% increase in COVID-19 and coronavirus themed phishing emails.
The high percentage of businesses that have experienced phishing attacks during the COVID-19 lockdown indicates many SMEs need to augment their anti-phishing defenses. There is also a need for further training to be provided to employees, as the emails are being opened and links are being clicked.
On the training front, formal training sessions may be harder to administer with so many employees working remotely. Consider conducting short training sessions via teleconferencing platforms and sending regular email alerts warning about the latest techniques, tactics and procedures being used in targeted attacks on remote workers. Phishing simulation exercises can be hugely beneficial and will help to condition workers to check emails thoroughly and report any threats received. These simulations also help identify which employees need further training to help them recognize potential phishing attacks.
Of course, the best way to ensure that employees do not open phishing emails and malicious attachments is to ensure they are not delivered to employees’ inboxes. That requires an advanced spam filtering solution.
Many SMEs and SMBs have now moved to an Office 365 hosted email solution, in which case email filtering will be taking place using Microsoft’s Exchange Online Protection – The default spam filtering service that protects all office 365 users. If you are reliant on this solution for filtering out phishing emails and other types of malicious messages, you should consider adding a third-party solution on top of EOP.
Exchange Online Protection provides a reasonable level of security and can block phishing emails and known malware threats, but it lacks the features of more advanced spam filtering solutions and cloud-based email security gateways, such as machine learning and predictive technology to identify attacks that have not been seen before.
As an additional protection against phishing attacks, a web filtering solution should be considered. In the event of a phishing email arriving in an inbox, a web filter serves as an additional layer of protection to prevent attempts by employees to visit websites linked in the emails. When an attempt is made to visit a known phishing website or web content that violates your acceptable internet usage policies, access will be blocked and the user will be directed to a local web page telling them why access has been denied.
Multi-factor authentication should also be implemented for email to ensure that in the event that credentials are compromised, a second factor must be provided before access to the email account is granted.

Data obtained by the UK think tank Parliament Street has revealed the extent to which universities are being targeted by cybercriminals and the sheer number of spam and malicious emails that are sent to the inboxes of university staff and students.
Data on malicious and spam email volume was obtained by Parliament Street through a Freedom of Information request. The analysis of data from UK universities showed they are having to block millions of spam emails, hundreds of thousands of phishing emails, and tens of thousands of malware-laced emails every year.
Warwick University’s figures show that more than 7.6 million spam emails were sent to the email accounts of staff and students in the final quarter of 2019 alone, which included 404,000 phishing emails and more than 10,000 emails containing malware.
It was a similar story at Bristol University, which received more than 7 million spam emails over the same period, 76,300 of which contained malware. Data from the London School of Hygiene and Tropical Medicine revealed more than 6.3 million spam emails were received in 2019, which included almost 99,000 phishing emails and more than 73,500 malware attacks. 12,773,735 spam and malicious emails were received in total for 2018 and 2019.
Data from Lancaster University revealed more than 57 million emails were rejected for reasons such as spam, malware, or phishing, with 1 million emails marked as suspected spam. The figures from Imperial College London were also high, with almost 40 million emails blocked in 2019.
Like attacks on companies, cyberattacks on universities are often conducted for financial gain. These attacks attempt to deliver malware and obtain credentials to gain access to university networks to steal data to sell on the black market. Universities store huge amounts of sensitive student data, which is extremely valuable to hackers as it can be used for identity theft and other types of fraud. Attacks are also conducted to deliver ransomware to extort money from universities.
Universities typically have high bandwidth to support tens of thousands of students and staff. Attacks are conducted to hijack devices and add them to botnets to conduct a range of cyberattacks on other targets. Email accounts are being hijacked and used to conduct spear phishing attacks on other targets.
Nation state sponsored advanced persistent threat (APT) groups are targeting universities to gain access to intellectual property and research data. Universities conduct cutting edge research and that information is extremely valuable to companies who can use the research data to develop products to gain a significant competitive advantage.
Universities are seen as relatively soft targets compared to organizations of a similar size. Cybersecurity defenses tend to be far less advanced, and the sprawling networks and number of devices used by staff and students make defending networks difficult.
With the number of cyberattacks on universities growing, leaders of higher education institutions need to take steps to improve cybersecurity and prevent the attacks from succeeding.
The majority of threats are delivered via email, so advanced email security defenses are essential, and that is an area where TitanHQ can help.
Independent test show SpamTitan blocks in excess of 99.97% of spam email, helping to keep inboxes free of junk email. SpamTitan incorporates dual anti-virus engines to block known threats, machine learning to identify new types of phishing attacks, and sandboxing to detect and block zero-day malware and ransomware threats. When email attachments pass initial tests, suspicious attachments are sent to the sandbox for in depth analysis to identify command and control center callbacks and other malicious actions. SpamTitan also incorporates SPF and DMARC controls to block email impersonation attacks, data loss prevention controls for outbound messages and controls to detect potential email account compromises.
If you want to improve cybersecurity defenses, start with upgrading your email security defenses with SpamTitan. You may be surprised to discover the little investment is required to significantly improve your email security defenses. For more information, call the TitanHQ team today.
Several new COVID-19 phishing email campaigns have been detected over the past few days that are exploiting fear about the novel coronavirus pandemic to deliver computer viruses and steal sensitive information.
People are naturally worried about getting infected with the real virus especially with the high fatality rate, so emails related to COVID-19 are likely to be opened.
Some of the phishing emails that have been intercepted are easy to identify as malicious. They are poorly written with spelling mistakes and grammatical errors, but some campaigns have been expertly crafted and are highly convincing and are likely to catch out many people.
The first COVID-19 phishing campaigns were detected in January and the number has steadily grown over the past few weeks. Many different threat groups are now using COVID-19 phishing lures to fool the unwary into disclosing credentials, visiting malicious links, or downloading malware.
The World Health Organization (WHO) has issued a warning after several phishing campaigns were detected that impersonated WHO. The emails claimed to provide essential information about cases in the local area along with advice on how to avoid infection. One of the most recently detected campaigns claimed to provide “Coronavirus Updates” with the emails containing a ZIP file attachment that appeared to be a PDF file – MYHEALTH.PDF. However, the file was actually an executable file – MYHEALTH.exe. If the file was opened, it triggered the download of GULoader, which in turn downloads Formbook malware from Google Drive. Another similar campaign included a Word attachment that downloaded the TrickBot Trojan, which is being used to deliver Ryuk ransomware as a secondary payload.
The Centers for Disease Control and prevention is also being impersonated. One campaign claims the novel coronavirus had become an airborne threat and warns of new cases in the local area. The emails appear to have been sent from a legitimate CDC email account – CDC-Covid19[@]cdc.gov. The emails include an attachment titled “Safety Precautions” which appears to be an Excel spreadsheet, but it actually a .exe executable file. Double clicking on the file attachment triggers the download of a banking Trojan.
Email and text-based phishing campaigns are targeting UK taxpayers and impersonate HM Revenue and Customs (HMRC). The emails include a legitimate HMRC logo and advise the recipients about a new COVID-19 tax refund program. According the emails, the refund program was set up in cooperation with National Insurance and National Health Services and allows taxpayers to claim back tax to help deal with the coronavirus pandemic. In order to receive the refund, the user is told they must supply their name, address, mother’s maiden name and their bank card number.
In the past few days, a web-based malware distribution campaign has been identified. Several websites are now displaying world maps and dashboards that allow people to track the spread of the virus and find out about the location of new cases. People are naturally concerned about cases in their local area, and the website maps are attracting a lot of visitors.
Shai Alfasi, a security researcher at Reason Labs, discovered several websites using fake versions of maps and dashboards. The websites prompt users to download an application that allows them to track infections in real-time. The application is an executable file that delivers the AZORult information stealer.
With COVID-19 infections increasing and showing no sign of slowing, COVID-19 phishing campaigns are likely to continue. Organizations should raise awareness of the threat of COVID-19 phishing attacks with their employees and ensure appropriate technical solutions are implemented to block web and email-based attacks. TitanHQ can help with the latter and can provide advanced email and web security solutions to block these attacks. If you have not yet implemented a web filter or email security solution to protect your Office 365 accounts, now is a good time to start. Contact TitanHQ today for further information.
Microsoft has announced it has taken control of the U.S. infrastructure of the Necurs botnet and has taken steps to prevent the botnet operators from registering new domains and the rebuilding the Necurs infrastructure.
The Scale of the Necurs Botnet
The Necurs botnet first appeared in 2012 and has grown into one of the largest spam and malware distribution networks. The botnet consists of around 9 million devices that have been infected with Necurs malware. Each device within the botnet is under the control of the cybercrime group behind the botnet.
The Necurs botnet is used to commit a wide range of cybercrimes by the operators of the botnet as well as other cybercriminal groups who rent out parts of the botnet as a service. The Necurs botnet was used for malware and ransomware distribution, cryptocurrency mining, and attacks on other computers to steal credentials and confidential data. The Necurs botnet also has a distributed Denial of Service (DDoS) module capable of performing massive DDoS attacks, although this function is yet to be used.
The main use of the botnet is spamming. The botnet has been used to send vast quantities of spam email, including emails pushing fake pharmaceutical products, pump and dump stock scams, and Russian dating scams. To give an example of the scale of the spamming, over a 58-day period of observation, Microsoft found that a single Necurs malware-infected computer had sent out 3.8 million spam emails to 40.6 million email accounts. That is just one infected device out of 9 million! In 2017, the botnet was being used to spread Dridex and Locky ransomware at a rate of around 5 million emails an hour and between 2016 and 2019 the botnet was responsible for 90% of email-based malware attacks.
The Takedown of Necurs Infrastructure
Microsoft has tracked the criminal activity of the Necurs botnet operators for 8 years. The gang is believed to be Evil Corp, the Russian cybercriminal group behind the Dridex banking Trojan. Evil Corp has been named the most harmful cybercrime group in the world.
The takedown of the Necurs botnet involved a coordinated effort by Microsoft and partners in 35 countries. Microsoft obtained an order from the U.S. District Court for the Eastern District of New York on March 5, 2020 to seize the U.S. domains used by the botnet operators. These domains were used to issue commands to the 9 million infected computers.
Simply seizing the domains would not be sufficient to take down the botnet, as the botnet’s command and controls servers could be rapidly rebuilt. Domains used by the threat actors are often taken down, so new domains are constantly registered weeks or months in advance.
The key to long-term disruption of the botnet was cracking the algorithm used by the threat actors to generate new domains. Microsoft analyzed the algorithm and calculated more than 6 million domains that would be used by the threat actors over the next 25 months. Steps have been taken to prevent those domains from being registered and becoming part of the Necurs infrastructure.
The 9 million devices around the world are still infected with Necurs malware. Microsoft and its partners have identified the infected devices and are working with ISPs and CERT teams around the world to rid those devices of the malware.
Just a few days after new figures from the FBI confirmed business email compromise scams were the biggest cause of losses to cybercrime, news broke of a massive cyberattack on a Puerto Rico government agency. Cybercriminals had gained access to the email account of an employee, understood to work in the Puerto Rico Employee Retirement System.
The compromised email account was used to send requests to other government agencies requesting changes be made to standard bank accounts for remittance payments. Since the email account used was trusted, the changes to bank accounts were made. Scheduled payments were then made as normal and millions of dollars of remittance payments were wired to attacker-controlled bank accounts.
The Puerto Rico Industrial Development Company, a state-owned corporation that drives economic development of the country, was one of the worst hit. Emails were received requesting changes to bank accounts and two payments were made. The first payment of $63,000 was made in December and another payment of $2.6 million in January. Other departments were also targeted, including the Tourism Company. The latter made a payment of $1.5 million. In total, the scammers attempted to steal around $4.73 million.
The business email compromise scam was uncovered when those payments were not received by the correct recipients. Prompt action was then taken to block the transfers and some of the payments were frozen, but the government has not been able to recover around $2.6 million of the stolen funds.
A full investigation has been launched to determine how the attackers gained access to the email account to pull off the scam. While the method used has not been confirmed, BEC attacks usually start with a spear phishing email.
A phishing email is sent to a person of interest requesting urgent action be taken to address a problem. A link is supplied in the email that directs the user to a website that requests their email account credentials. The account can then be accessed by the attacker. Attackers often set up mail forwarders to receive a copy of every email sent to and from the account. This enables them to learn about the company and typical payments and construct highly convincing scam emails.
Once access to a corporate email account is gained, the BEC scam is much harder to identify and block. The best defense is to ensure that the initial phishing emails are not delivered, and that is an area where TitanHQ can help.
A novel coronavirus phishing campaign has been detected that uses scare tactics to trick users into infecting their computer with malware.
The World Health Organization has now declared the 2019 novel coronavirus outbreak a global emergency. The number of cases has increased 10-fold in the past week with almost 9,100 cases confirmed in China and 130 elsewhere around the world.
A worldwide health crisis such as this has naturally seen huge coverage in the press, so it is no surprise that cybercriminals are capitalizing on the concern and are using it as a lure in a malspam campaign to scare people into opening an email attachment and enabling the content.
A novel coronavirus phishing campaign has been detected that uses a fake report about the coronavirus to get email recipients to open a document that details steps that should be taken to prevent infection. Ironically, taking the actions detailed in the email will actually guarantee infection with a virus of a different type: Emotet.
The coronavirus phishing campaign was identified by IBM X-Force researchers. The campaign is targeted on users in in different Japanese prefectures and warning of an increase in the number of local confirmed coronavirus cases. The emails include a Word document attachment containing the notification along with preventative measures that need to be taken.
If the attachment is opened, users are told they must enable content to read the document. Enabling the content will start the infection process that will see the Emotet Trojan downloaded. Emotet is also a downloader of other malware variants. Other banking Trojans and ransomware may also be downloaded. Emotet can also send copies of itself to the victim’s contacts. Those messages may also be coronavirus related.
To add credibility, the Emotet gang makes the emails appear to have been sent by a disability welfare service provider in Japan. Some of the captured messages include the correct address in the footer.
More than 2,000 new infections have been confirmed in the past 24 hours in China and all of its provinces have now been impacted. Cases have now been reported in 18 other countries with Thailand and Japan the worst hit outside of China with 14 cases confirmed in each country. As the coronavirus spreads further and more cases are reported, it is likely that the Emotet gang will expand this campaign and start targeting different countries using emails in different languages. Kaspersky lab has also said that it has identified malspam campaigns with coronavirus themes that use a variety of email attachments to install malware.
Businesses can protect against Emotet, one of the most dangerous malware variants currently in use, by implementing a spam filtering solution such as SpamTitan that incorporates a sandbox where malicious documents can be analyzed in safety to check for malicious actions.

It has been well documented how much time businesses waste dealing with spam and there is no denying the threat that malicious spam emails (malspam) pose, but it is not just a problem for big business. Spam in academia is also a major problem.
A recent study published in the journal, Scientometrics, explores the cost of spam in academia. The study was primarily focused on spam emails sent by new, non-peer reviewed journals that are attempting to gain a share of the market. These journals are adopting the same spam tactics often used by scammers to sell cheap watches, cut price medications, and for phishing and spreading malware.
Three researchers – Jaime A. Teixeira da Silva, Aceil Al-Khatib, and Panagiotis Tsigaria – attempted to quantify the amount of time that is being wasted dealing with those messages and the losses that result.
To assess the extent of the problem, the researchers used figures from several studies on spamming to obtain an average number of targeted spam emails that academics receive each day. They opted for a conservative figure of 4-5 messages, per academic, per day. Most of those messages take just a few seconds to open and read but that time mounts up. They assumed an average time of 5 seconds per message – less than half a minute per day. That equates to $100 per researcher, per year at an average hourly rate of $50. Using the United Nations estimate of the number of researchers in academia globally, the total global cost of spam in academia was estimated to be $1.1 billion a year.
That figure is based on the lost time alone and does not factor in non-targeted spam emails – bulk unsolicited emails not specifically targeting researchers. Add in the time dealing with those messages and the global cost reaches $2.6 billion a year. To put the cost into perspective, $2.6 million is much more than the time researchers devote to peer review, which has been estimated at costing $1.9 billion a year. The figures do not include the considerable losses due to phishing, malware, and ransomware attacks. Factor in those costs and the losses would be several orders of magnitude higher.
Co-author of the study, Panagiotis Tsigaris, a professor of economics at Thompson Rivers University in Canada, explained that there is no silver bullet when it comes to dealing with spam and suggested several ways that the cost of spam in academia could be reduced.
Tsigaris suggests that penalties should be increased for publishing in predatory journals, and that academics should be educated about spam email and improvements should be made to email filtering technology.

Cyberattacks on managed service providers have been increasing over the past few months and they are now a key target for hackers. If a hacker can gain access to the systems of a managed service provider, their remote administration tools can be used to launch attacks on their clients.
There have been several major cyberattacks on managed services providers in the past few weeks, with nation state-backed hacking groups targeting MSPs serving enterprises and ransomware gangs are conducting attacks on MSPs serving small and medium sized businesses.
Three major cyberattacks on managed service providers serving healthcare organizations in the United States have been reported in the past two months. All three have affected more than 100 healthcare clients and one impacted 400.
In late November, the Milwaukee-based managed IT service provider, Virtual Care Provider Inc., was attacked with Ryuk ransomware. The attack started on November 17, 2019 and affected all of its clients’ data. Around 110 nursing homes and acute care facilities were prevented them from accessing their patients’ medical records. The consequences for its clients were dire. Assisted living facilities and nursing homes were prevented from billing for Medicaid, which meant essential funding was not provided and nursing homes were prevented from ordering essential drugs for patients. Virtual Care Provider was issued with a $14 million ransom demand, which the company could not afford to pay. The managed service provider had around 20% of its services affected and had to rebuild around 100 servers.
The ransomware was deployed as a secondary payload by the TrickBot Trojan. TrickBot had been installed on its network 14 months previously via a malicious email attachment.
A few weeks later, a Colorado-based managed service provider serving dental practices was attacked with ransomware. Complete Technology Solutions was infected with a ransomware variant called Sodinokibi. First the MSP was attacked, then its remote administration tools were used deploy ransomware on the networks of more than 100 dental practices. A ransom demand of $700,000 was issued, which the MSP refused to pay. Its clients are now having to pay the attackers for the keys to decrypt their files. Only a few that had backups stored off the network were able to recover without paying the ransom.
This is the second such attack to affect a company serving the dental industry. The dental record backup service provider, PerCSoft, was also attacked with Sodinokibi ransomware. That attack affected approximately 400 dental practices. CyrusOne was also attacked with Sodinokibi ransomware and its managed services division and six of its clients were affected.
It is not only ransomware that is being used in the attacks. Nation-state threat groups such as APT10 are also targeting MSPs. Their aims are different. The attacks are being conducted to gain access to the intellectual property of their enterprise customers.
As cyberattacks on managed service providers increase, MSPs must ensure that they have adequate defenses in place to keep the hackers at bay. This is an area where TitanHQ can help. TitanHQ is the leading provider of cloud-based email and web security solutions for managed service providers that serve the SMB market.
TitanHQ offers a trio of solutions for MSPs under the TitanShield program. SpamTitan email security is a powerful cloud-based solution that keeps inboxes free of spam, phishing emails, and malware. SpamTitan incorporates SPF and DMARC to block email impersonation attacks, uses dual antivirus engines to detect known malware threats, and heuristics and sandboxing to identify and block zero-day threats.
WebTitan Cloud is a 100% cloud-based DNS filtering solution that works seamlessly with SpamTitan to block web-based phishing attacks and malware downloads. The solution allows you to monitor and identify malicious threats in real time, and includes AI-driven protection against active and emerging phishing URLs, including zero-minute threats.
The third solution is ArcTitan, a cloud-based email archiving solution that provides protection against data loss and helps MSPs and their clients meet their compliance obligations. ArcTitan serves as a black box flight recorder for email and stores email data securely in the cloud on Replicated Persistent Storage on AWS S3. When emails need to be searched and recovered, the searches are lightning fast. ArcTitan can search up to 30 million emails a second.
ArcTitan has recently been moved to a brand new system, with the service delivered as a highly available, self-healing horizontally scaled Kubernetes cluster. Within that cluster are many different components working in harmony together, but independently. Should any component go down, that component can be taken offline and repaired with no impact on the others, ensuring a much more reliable service with minimal or no disruption during an outage. With ArcTitan, email is protected from cyberattacks.
These solutions are not only an ideal for improving the security posture of MSP clients, they can help to ensure that MSP systems are protected from attack. All TitanHQ solutions are quick and easy to implement, have a low management overhead, and are API-driven so they can easily be incorporated into MSP’s remote management and monitoring systems.

Recent research has highlighted just how important it is for businesses to implement a range of defenses to ensure phishing emails are not delivered to inboxes and how business phishing protections are failing.
The studies were conducted to determine how likely employees are to click on phishing emails that arrive in their inboxes. Alarmingly, one study indicated almost three quarters of employees were fooled by a phishing test and provided their credentials to the attacker. In this case, the attacker was the consultancy firm Coalfire.
71% of the 525 businesses that were tested had at least one employee disclose login credentials in the phishing test, compared to 63% last year. At 20% of businesses, more than half of the employees who were tested fell for the phishing scam, compared to 10% last year.
A second study conducted by GetApp revealed a quarter of 714 surveyed businesses said they had at least one employee who responded to a phishing attack and disclosed their login credentials and 43% of businesses had employees that had clicked on phishing emails. The study also revealed only 27% of businesses provide security awareness training to employees, only 30% conduct phishing simulations, and 36% do not have multi-factor authentication in place on email.
The Importance of Layered Phishing Defenses
To mount an effective defense against phishing and other cyberattacks, a defense in depth approach to security is required.
With layered defenses, businesses are not replying on a single solution to block phishing attacks. Multiple defenses are put in place with the layers overlapping. If one measure proves to be ineffective at blocking a phishing email, others are in place to provide protection.
One area where many businesses fail is relying on Office 365 anti-phishing controls. A study by Avanan showed Office 365 phishing defenses to be effective at blocking most spam emails, but 25% of phishing emails were delivered to inboxes.
What is required is an advanced anti-spam and anti-phishing platform that can be layered on top of Office 365 to ensure that these phishing emails are blocked. SpamTitan can be seamlessly implemented in Office 365 environments and provides superior protection against phishing and malware attacks. SpamTitan blocks more than 99.9% of spam and phishing emails, 100% of known malware, and incorporates a host of features to identify zero-day threats.
As good as SpamTitan is at blocking email threats, other layers should be implemented to block phishing attacks. If a phishing email arrives in an inbox, a web filter will provide protection by blocking attempts by employees to visit phishing websites and sites hosting malware. WebTitan is a powerful DNS filtering solution that protects against the web-based element of phishing attacks. WebTitan adds an extra layer to phishing defenses and will block attempts by employees to visit malicious sites.
If an attacker succeeds in obtaining the credentials of an employee, it is important that those credentials cannot be used to gain access to the account. That protection is provided by multi-factor authentication. Multi-factor authentication is not infallible, but it will prevent stolen credentials from being used to access accounts in the majority of cases.
Security awareness training is also vital. Employees are the last line of defense and that defensive line will be tested. If employees are not trained how to identify phishing emails and other email security threats, they cannot be expected to recognize threats when they land in inboxes. An annual training session is no longer enough, considering how many phishing attacks are conducted on businesses and how sophisticated the attacks are becoming.
Security awareness training should consist of an annual training session with regular refresher training sessions throughout the year. Employees should be kept up to date on the latest tactics being used by cybercriminals to help them identify new scam emails that may bypass email security defenses. Phishing simulation exercises are also important. If these simulations are not conducted, businesses will have no idea how effective their training sessions have been, and which employees have not taken the training on board.
A new phishing campaign has been detected that is targeting Office 365 admins, whose accounts are far more valuable to cybercriminals than standard Office 365 accounts.
A standard Office 365 email account can used for spamming or conducting further phishing attacks on the organization or business contacts. However, there is a problem. When the account is used for phishing, the sent messages are likely to be noticed by the user. Failed delivery messages will also arrive in the user’s inbox. The account may only be able to be used for a short time before an account compromise is detected.
The attackers targeting Office 365 admins aim to compromise the entire domain. Office 365 admins can create new accounts on the domain, which are then used for phishing. Since the only person using that account is the attacker, it is likely the malicious actions will not be noticed, at least not as quickly. The only person who will see the failed delivery messages and sent emails is the attacker.
The newly created account abuses trust in the business domain. Any individual to receive such a phishing message may mistakenly believe the email is a legitimate message from the company. The messages also take advantage of the reputation of a business. Since the business domain will have been used only to send legitimate messages, the domain will have a high trust score. That makes it far more likely that the emails being sent from the new account will be delivered to inboxes and will not be picked up by Office 365 spam filters. The Office 365 admin may also have access to all email accounts on the domain, which will allow the attacker to steal a huge amount of email data.
In theory, Office 365 admins should be better at identifying phishing emails than other employees in the organization as they usually work in the IT department; however, these emails are very realistic and will likely fool many Office 365 admins.
The lure being used is credible. The emails appear to have been sent by Microsoft and include the Microsoft and Office 365 logos. The emails claim that the organization’s Office 365 Business Essentials invoice is ready. The user is told to sign into the Office 365 admin center to update their payment information, set their Message Center preferences, and edit their release preferences or join First Release and set these up if they have not done so already. The emails include an unsubscribe option and are signed by Microsoft and include the correct contact information. The emails also link to Microsoft’s privacy statement.
The embedded hyperlinks in the emails link to an attacker-controlled domain that is a carbon copy of the official Microsoft login page. If the user’s credentials are entered, they are captured by the attacker.
This campaign highlights how important it is to have layered email security defenses in place to block phishing attacks. Many phishing emails bypass standard Office 365 anti-phishing controls so additional protection is required.
An advanced anti-phishing solution such as SpamTitan should be layered on top of Office 365 to provide greater protection against sophisticated phishing attacks. Approximately 25% of all phishing emails bypass standard Office 365 phishing protections.
Another anti-phishing layer that many businesses have yet to implement is a web filter. A web filter, such as WebTitan, provides protection when messages are delivered to inboxes, as it blocks attempts by employees to visit phishing websites. When a link to a known phishing website is clicked, or the user attempts to visit a questionable domain, they will be directed to a block page and the phishing attack will be blocked.
The aim of this post is to provide you with some easy to adopt email security best practices that will greatly improve your organization’s security posture.
Email is the Most Common Attack Vector!
It is a certainty that business email systems will be attacked so email security measures must be implemented. The best form of email security is to do away with email altogether, but since businesses rely on email to communicate with customers, partners, and suppliers, that simply isn’t an option.
Email not only makes it easy to communicate with the people you need to for your business to operate, it also allows cybercriminals to easily communicate with your employees and conduct phishing attacks, spread malware and, if a corporate email account is compromised, communicate with your customers, partners and suppliers.
Email security is therefore essential, but there is no single solution that will protect the email channel. A spam filtering solution will stop the majority of spam and malicious email from reaching inboxes, but it will not block 100% of unwanted emails, no matter what solution you implement. The key to robust email security is layered defenses. If one defensive measure fails, others are in place that will provide protection.
You need a combination of technical, physical, and administrative safeguards to secure your email. Unfortunately, there is no one-size-fits-all approach that can be adopted to secure the email channel but there are email security best practices that you can adopt that will improve your security posture and make it much harder for cybercriminals to succeed.
With this in mind, we have outlined some of the most important email security best practices for your business and your employees to adopt.
Email Security Best Practices to Implement Immediately
Cybercriminals will attempt to send malware and ransomware via email, and phishing tactics will be used to steal sensitive information such as login credentials, so it is important to be prepared. Listed below are 8 email security best practices that will help you keep your email system secure. If you have not yet implemented any of these best practices, or have only done so partially, now is the time to make some changes.
Develop a Cybersecurity Plan for Your Business
We have included this as the first best practice because it is so important. It is essential for you to develop a comprehensive cybersecurity plan for your entire organization as not all threats arrive via email. Attacks come from all angles and improving email security is only one of the steps you need to take to improve your overall cybersecurity posture.
There are many resources available to help you develop a cybersecurity plan that addresses all cyber risks. The Federal Communications Commission has developed a Cyberplanner to help with the creation of a custom cybersecurity plan and the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) has recently issued a Cyber Essentials Guide for Small Businesses and Governments. Take advantage of these and other resources to develop an effective cybersecurity plan.
Implement an Advanced Spam Filtering Solution
A spam filter serves as a semi-permeable membrane that prevents email threats from being delivered to inboxes and lets genuine emails pass through unimpeded. This is the single most important security measure to implement to protect against email threats and productivity-draining spam.
If you use Office 365 you will already have some protection, as Office 365 includes a spam filter and anti-virus software, but it falls short on phishing protection and will not block zero-day malware threats. You need layered defenses to secure email which means a third-party spam filter should be used on top of Office 365. Research from Avanan showed 25% of phishing emails bypass Office 365 defenses.
There are many spam filtering services for SMBs, but for all round protection against known and zero-day threats, ease of implementation, ease of use, and price, SpamTitan is the best choice for SMBs.
Ensure Your Anti-Virus Solution Scans Incoming Emails
You will no doubt have anti-virus software in place, but does it scan incoming emails? Email is one of the main ways that malware is delivered, so anti-virus software for email is a must. This does not necessarily mean you need a different antivirus solution. Your existing solution may have that functionality. Your spam filter is also likely to include AV protection. For example, SpamTitan incorporates dual anti-virus engines for greater protection and a sandbox where email attachments are analyzed for malicious actions. The sandbox his used to detect and block zero-day malware – New, never-before seen malware variants that have yet to have their signatures incorporated into AV engines.
Create and Enforce Password Policies
Another obvious email security best practice is to create a password policy that requires strong passwords to be set. There is no point creating a password policy if it is not enforced. Make sure you implement a control measure to prevent weak passwords from being set. Weak passwords (password, 123456, or dictionary words for example) are easy to remember but also easy to guess. Consider that cybercriminals are not sitting at a computer guessing passwords one at a time. Automation tools are used that make thousands of password guesses a minute. It doesn’t take long to guess a weak password! You should also make sure rate limiting is applied to block an IP from logging in after a set number of failed login attempts.
It is a good best practice to require a password of at least 8 characters to be set, with a combination of upper- and lower-case letters, numbers, and symbols and to block the use of dictionary words. Consider allowing long passphrases to be used as these are easier for employees to remember. Check National Institute of Science and Technology (NIST) advice on secure password practices if you are unsure about creating a password policy.
Implement DMARC to Stop Email Impersonation Attacks and Domain Abuse
DMARC, or Domain-based Message Authentication, Reporting & Conformance to give it its full name, is an email protocol that uses Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to determine whether an email is authentic.
By creating a DMARC record you are preventing unauthorized individuals from sending messages from your domain. DMARC also lets you know who is sending messages from your domain, and it lets you set a policy to determine what happens to messages that are not authenticated, I.e. quarantine them or reject them. Some email security solutions, such as SpamTitan, incorporate DMARC authentication.
Not only DMARC help you block email impersonation attacks, it also prevents abuse of your domain. Your DMARC record tells receiving email servers not to accept messages sent from authenticated users, thus helping protect your brand.
Implement Multi-Factor Authentication
Multi-factor authentication is yet another layer you can add to your anti-phishing defenses. Multi-factor authentication, as the name suggests, means more than one method is used to authenticate a user. The first factor is usually a password. A second factor is also required, which is something a person knows or possesses. This could be a mobile phone, to which a one-time PIN code is sent, or a token on a trusted device.
This safeguard is vital. If a password is obtained, in a phishing attack for example, the password alone will not grant access to the email account without an additional factor being provided. A combination of a password, token, and one-time PIN is a good combination.
Train Your Employees and Train Them Again
No matter how tech savvy your employees appear to be, assume they known nothing about cybersecurity. They will certainly not routinely stick to email security best practices unless you train them to do so and then hammer the message home.
Before letting any employee have access to email, you should provide security awareness training. Your training should cover email security best practices such as never opening email attachments from unknown senders, never enabling content in documents unless the document has been verified as legitimate, and never to click hyperlinks in emails or send highly sensitive information such as passwords via email.
You must also train your employees how to recognize phishing emails and other malicious messages and tell them what to do when suspicious emails are received. Anyone with access to email or a computer must be provided with security awareness training, from the CEO down.
One training session is not enough. Even an annual training session is no longer sufficient. You should be providing regular training, be sending cybersecurity newsletters warning about the latest threats, and using other tools to help create a security culture in your organization.
Conduct Phishing Awareness Simulation Exercises
You have provided training, but how do you know if it has been effective? The only way to tell is to conduct tests and that is easiest with phishing simulation exercises. These are dummy phishing emails that are sent to employees when they are not expecting them to see how they respond. You maybe surprised at how many employees respond and disclose sensitive information, open attachments, or click links in the emails.
The aim of these emails is to identify people that have not taken their training on board. The idea is not to punish those employees, but to tell you who needs further training. There are several companies that can assist you with these exercises. Some even offer free phishing simulation emails for SMBs.

Phishers are constantly changing tactics and coming up with new ways to fool people into handing over their credentials or installing malware. New campaigns are being launched on a daily basis, with tried and tested lures such as fake package delivery notices, fake invoices and purchase orders, and collaboration requests all very common.
In a departure from these common phishing lures, one threat group has opted for a rarely seen lure, but one that has potential to be very effective: Fake court subpoenas. The emails use fear and urgency and are designed to get users to panic and click quickly.
This campaign has been running for a few weeks and is targeting users in the United Kingdom, although this scam could easily be adapted and used in attacks on users in other countries.
Many phishing scams have the goal of stealing credentials to allow email accounts or Office 365 accounts to be accessed. In this case, the aim of the attack is to spread information stealing malware called Predator the Thief.
The phishing emails appear to have been sent by the Ministry of Justice in the UK. The sender field has Ministry of Justice as the display name and the emails have the Ministry of Justice crest, although the actual email address suggests the email has come from the Department of Justice (DOJ).
The emails warn the user that they have been subpoenaed. They are supplied with a case number along with a date when they have been ordered to attend court.
The emails include a hyperlink which the user must click to find out details of the charge and the documents they will need to bring with them to court. Urgency is added by warning the recipient they only have 14 days to respond to provide notice, and that the court case will proceed without them if they do not respond.
The URL in the email is seemingly benign, as it links to Google Docs – a trusted website. Clicking the link will see the user first directed to Google Docs, then redirected to OneDrive. When the user arrives on the OneDrive site, a document is downloaded. That document contains a malicious macro that launches a PowerShell command that downloads Predator the Thief malware.
Predator the Thief is an information stealer that can take screenshots and steals email and FTP credentials, along with cryptocurrency wallets and browser information. In contrast to many browser information stealers, this malware variant doesn’t just target the main browsers, but a host of less popular browsers. Once information has been stolen, the malware cleans up and exits, which makes it harder for the infection to be detected.
Phishing scams such as this highlight the need for layered security. Naturally, an advanced anti-spam solution such as SpamTitan should be implemented to block these threats and ensure and ensure messages are not delivered to end users’ inboxes. SpamTitan also includes DMARC email authentication to block mail impersonation attempts and a sandbox where email attachments are analyzed for malicious actions.
SpamTItan blocks in excess of 99.9% of all malicious emails, but it is not possible to block 100% of threats no matter what email security solution you use. This is where another layer is required. WebTitan is a DNS filtering solution that blocks threats such as this at the point where a DNS lookup is performed. This allows malicious websites to be blocked before any content is downloaded. WebTitan can also be configured to block downloads of certain file types.
With these two solutions in place, your business will be well protected against phishing emails and web-based malware downloads.
A new Stripe phishing campaign has been detected that uses fake warnings advising users about an invalid account to lure people into divulging their credentials and bank account information.
Stripe is an online payment processor used by many online firms on their e-commerce websites to accept payments from their customers. As such, the company is perfect for spoofing as many people will be aware that the company processes payments and will think it reasonable that they need to provide credentials and bank account information to ensure payments are processed.
The scam starts with a phishing email supposedly from the Stripe Support department. The email advises the customer that the information associated with their account is currently invalid. The message is sent as a courtesy notice warning the user that their account will be placed on hold until the matter is corrected. The user is asked to review their details to correct the issue. A button is included in the email for users to click to do this.
The emails contain spelling mistakes and questionable grammar, so are likely to be identified as suspect by vigilant individuals. Security awareness training often teaches employees to hover their mouse arrow over a hyperlink to find out the true URL, but in this campaign it will not work. The attackers have added a title to the HTML tag of the embedded hyperlink so when the mouse arrow is hovered over the “Review your Details” button, that text will be displayed instead of the URL.
If that button is clicked, the user will be directed to a seemingly legitimate Stripe login page. The login box is a clone of the real login page and a series of boxes will be displayed, each requiring different information to be entered, including bank account and contact information.
When the user is required to enter their password, regardless of what is typed, the user will be advised that they have entered an incorrect password and will be asked to enter the password again. The user is then directed to the legitimate Stripe login page to make it appear they have been on the correct Stripe website all along.
Similar tactics are used in countless other phishing campaigns targeting other well-known companies. The presence of spelling mistakes and grammatical errors in messages should tip off end users that the email is a phishing attempt, but all too often end users fail to notice these errors and click and divulge sensitive information.
One issue is a lack of cybersecurity training in the workplace. If employees are not trained how to identify phishing emails, it is inevitable that some will end up falling for these scams and will divulge their credentials. Those credentials can be used to gain access to bank accounts or email accounts, with the latter often used to conduct further phishing attacks on the organization. One email account breach can easily lead to dozens of breached accounts.
For example, a phishing attack on a U.S. healthcare provider started with a single phishing email and led to 73 email accounts being compromised. As for cybersecurity awareness training, this is often nonexistent. One recent study on 2,000 employees in the United Kingdom revealed three quarters had received no workplace cybersecurity training whatsoever.
Protected by Microsoft Office 365 Anti-Phishing Controls? Are You Sure?
One in every 99 emails is a phishing email, so it is important to ensure your defenses are capable of blocking those messages. Many businesses mistakenly believe they are protected against these emails by Microsoft’s Office 365 anti-phishing controls. While those measures do block spam email and some phishing messages, one recent study by Avanan has shown 25% of phishing attacks sneak past Office 365 defenses and are delivered to inboxes. For an average firm that means several phishing emails will reach end users’ inboxes every day. To ensure your business is protected against phishing attacks, additional anti-phishing controls are required on top of Office 365.
Businesses can protect their Office 365 accounts against phishing by layering SpamTitan on top of Office 365. SpamTitan is an advanced anti-phishing and anti-malware solution that provides superior protection against phishing, malware, spear phishing, and zero-day attacks.
Heuristics rules are used to analyze message headers and these rules are constantly updated to include the latest threats. Bayesian analysis and heuristics are used to check message content, and along with machine learning techniques, new threats are blocked and prevented from reaching inboxes. Sandboxing is also used to assess email attachments for malicious code used to install malware in addition to dual-AV engines that scan for known malware.
These advanced measures ensure that Office 365 inboxes are kept free from malware and phishing emails. These advanced capabilities along with the ease of implementation and use and industry-leading customer support are why SpamTitan is the leading provider of anti-spam and anti-phishing solutions for SMBs and managed service providers that serve the SMB market.

G2 Crowd, the independent peer-to-peer business software review site, has published its G2 Crowd Grid® Summer 2019 Report for Cloud Email Security. For the third consecutive quarter, SpamTitan has been named the leading cloud email security provider having been awarded the highest score for customer satisfaction.
G2 Crowd is the largest tech marketplace for businesses. The site attracts more than 3 million visitors and contains more than 843,500 reviews from verified software users. The reviews and Grid Reports are relied upon by countless businesses to help them make better software buying decisions.
Each quarter, G2 Crowd produces Grid reports that highlight the key players in different software categories. The G2 Crowd Grids are used to rank software solutions based on market presence and user satisfaction and categorize each as wither a niche player, contender, high performer, or leader. To be named a leader, a product must have a strong market presence and high user satisfaction level.
Market presence is determined by the size of the company, its social impact, and market share. The user satisfaction score is calculated from amalgamated reviews from verified users of the software.
User reviews are important when choosing a software solution. If the software is difficult to use, fails to live up to expectations, or does not provide the required functionality, staff will avoid using it as much as possible. For a security solution that is particularly bad news.
The Summer 2019 report includes 9 email security solutions. SpamTitan achieved the highest overall customer satisfaction score – 97% – of all nine solutions by some distance. The next highest customer satisfaction scores were for Proofpoint Email Security & Protection (75%), Area 1 Security (69%), and Barracuda Email Security Gateway (61%).
In addition to the Grid reports, amalgamated scores are included for six different customer satisfaction criteria: Ease of setup, ease of use, ease of admin, ease of doing business, quality of support, and meets requirements. Once again, SpamTitan topped the list with the highest score for ease of setup (92%) and ease of use (92%) and was one of only two solutions that achieved scores of over 90% in each of the six categories.
“The overwhelmingly positive feedback on G2 Crowd from users of SpamTitan is indicative of our commitment to ensuring the highest levels of customer success,” said Ronan Kavanagh, CEO, TitanHQ. “That’s an incredible achievement for a product that is significantly more affordable than the market leaders.”
Cybercriminals are using SharePoint to send malicious documents to businesses in the United Kingdom. This tactic has seen many messages pass through email security defenses undetected and arrive in inboxes.
The campaign appears to be targeting businesses in the financial services and aims to obtain Office 365 credentials and username/password combos from other email service providers. Those credentials can be used to gain access to sensitive information in email accounts and cloud storage repositories such as OneDrive.
In the latest campaign, the attacker used a compromised email account at a London legal firm to send emails to employees of businesses in the financial services sector. The attacker uses SharePoint to send a request to review a document. In order to view the document, the user is required to click an embedded hyperlink in the email.
If that link is clicked, the user is directed to SharePoint and onto another malicious URL where they are requested to download a OneNote document. In order to download that document, the user is required to enter their login credentials.
Since the initial URL is for the SharePoint domain, many email security solutions fail to identify the link as malicious. Similar tactics have been used in phishing campaigns that link to OneDrive, Citrix ShareFile, Google Drive, and Windows.net. Since the domains are thought to be benign and the email messages do not contain any malware, the messages are delivered to end users.
The URL used in this campaign is likely to arouse suspicion even though it is a SharePoint domain, but not all users carefully check URLs and the full URL may not be visible on mobile devices, which increases the risk of an end user being fooled into disclosing their login credentials. The spoofed OneDrive for Business portal to which the user is directed is also a poor imitation, but it is sufficiently realistic to fool many end users. Other identified phishing campaigns using file sharing websites are far more convincing and are unlikely to be detected as malicious even by security conscious employees.
When credentials are compromised, the email account is often used to send further phishing emails to other individuals in the organization. Since those emails come from an internal account, users are more likely to respond. The attackers can also view past message threats in the compromised account and use those messages to continue a conversation. The messaging style of the account holder can also be mimicked to add further realism to the phishing emails. Typically, businesses discover one email account has been compromised, but the investigation reveals the attack is far more widespread and many email accounts have been compromised. Once recent phishing attack on a U.S. healthcare provider saw an astonishing 72 email accounts compromised!
To block these threats, an advanced email security solution is required. Businesses should look for a solution that incorporates DMARC. DMARC incorporates SPF and DKIM email authentication protocols and verifies that the IP address used to send the email is authorized to send emails from that domain. If that check fails, the email is blocked. This is one of the most important and most effective methods of detecting and blocking email impersonation attacks, including BEC attacks and lateral phishing attempts.
Fortunately, a combination of an advanced spam filtering solution and end user security awareness training will help to ensure that emails do not reach inboxes and, if they do, that employees will be alert to the threat and will avoid clicking the link and disclosing their credentials.
An innovative phishing campaign has been discovered that uses branded Microsoft Office 365 login pages to trick victims into believing they are logging into their genuine Office 365 account.
The phishing emails warn the user that a message synchronization failure has blocked the delivery of emails to the user’s account. A link is supplied with the anchor text “Read Message” which directs the user to a fake Office 365 login page where they can review the messages and decide what to do with them.
If the user clicks on the link, their email address will be checked and validated, and the user will be directed to the phishing page. What makes this campaign unique is the check allows the attackers to scrape the branded tenant Office 365 login page used by the company via HTTP GET requests. The company’s custom background and logo are added dynamically to the phishing page. If a company does not have a custom login page, the standard Office 365 background is used.
The login pages are clones of the tenant pages, so they are unlikely to be recognized as fake by users. The phishing pages are also hosted on legitimate cloud storage infrastructure. The domains include either the blob.core.windows.net or azurewebsites.net domains, which have valid Microsoft SSL certificates. The result is a highly convincing campaign that is likely to fool many employees into divulging their login credentials.
Microsoft Office 365 Users are Under Attack!
Microsoft Office 365 is the most widely adopted cloud service by user count and has more than 155 million active users. 1 in 5 U.S. employees use at least one Office 365 service and half of businesses that use cloud services use Office 365. With such high numbers it is no surprise that Office 365 users are being targeted.
What is of major concern is the number of phishing emails that are bypassing standard Office 365 phishing defenses. A study by Avanan this year showed 25% of phishing emails bypass Office 365 defenses and arrive in employees’ inboxes.
When access is gained to one email account, it can be used for lateral phishing attacks on other employees in the organization. The goal of the attackers is to compromise as many accounts as possible and, ideally, an administrator account. Compromised accounts can also be used for BEC attacks, credentials can be used to access other Office 365 resources, and email accounts can be plundered for sensitive data.
How to Protect Your Business and Block Office 365 Phishing Attacks
There are three key measures to take to improve your defenses against Office 365 phishing attacks. The most important step is to improve anti-phishing protections with a third-party anti-spam and anti-phishing solution.
SpamTitan can be implemented in minutes and will provide superior protection against phishing attacks on Office 365 accounts. The solution has been independently tested and shown to block more than 99.9% of spam emails and 100% of known malware. A sandboxing feature allows suspicious attachments to be detonated in a safe and secure environment where all actions are analyzed for malicious activity and DMARC authentication of emails provides protection from email impersonation attacks that usually bypass Office 365 filters.
No anti-phishing solution will provide total protection against phishing attacks, so it is important to ensure that employees receive security awareness training. The workforce should be taught about the risks of email attacks and how to identify phishing emails. With training, you can turn your employees into strong last line of defense.
Even the most security-conscious employee could be fooled into disclosing their Office 365 credentials by a sophisticated phishing email. It is therefore important to implement 2-factor authentication.
2-factor authentication requires a second method of authenticating users, other than a password, when they attempt to login from an unfamiliar location or new device. In the event of credentials being compromised, account access can be blocked by -factor authentication. However, 2-factor authentication is not infallible, so businesses should not rely on this measure alone to protect their Office 365 accounts.

A new CAPTCHA phishing scam has been detected which is being used to trick users into downloading a malicious file that intercepts multi-factor authentication codes on a user’s smartphone. With the codes, hackers can perform a more extensive attack and gain access to a much wider range of resources such as email and bank accounts.
When a visitor lands on the phishing page, a check is performed to determine what device is being used. If the user is on an Android device, a malicious APK file is downloaded to their device. Any other platform will receive a zip file containing malware.
A fake version of the familiar Google reCAPTCHA is displayed on the phishing page. It closely resembles the legitimate version, although it does not support sound and the images do not change when they are clicked. The fake reCAPTCHA is housed on a PHP webpage and any clicks on the images are submitted to the PHP page, which triggers the download of the malicious file. This campaign appears to be focused on mobile users.
On an Android device, the malicious APK intercepts PIN codes from two-factor authentication messages, which allow the attackers to gain access to the user’s bank account. With these PIN codes, an email account can also be compromised, which would allow further accounts to be compromised by requesting password resets.
A successful attack could see several accounts used by an individual subjected to unauthorized access. Businesses are also attacked in a similar manner. Successful attacks on businesses could give the attackers access to huge volumes of sensitive company data and even infrastructure resources.
This method of delivering malware is nothing new and has been around since 2009. A CAPTCHA phishing campaign was detected in February 2018 attempting to download a malicious file, and a similar campaign was run in 2016.
A method of attack is adopted for a while then dropped. While it is possible to prepare the workforce for phishing attacks such as this through training, security awareness training alone is not enough as tactics frequently change, and new methods of attack are frequently developed.
As this attack shows, two-factor authentication is far from infallible. In addition to this method of obtaining 2FA codes, the SS7 protocol used to send SMS messages has flaws that can be exploited to intercept messages.
Security awareness training and 2FA are important, but what is required on top of these protections is a powerful anti-spam and anti-phishing solution. Such a solution will block phishing emails at the gateway and make sure they are not delivered to inboxes.
It is important to choose a solution that provides protection against impersonation attacks. Many phishing campaigns spoof a familiar brand or known individual. A solution that incorporates Domain-based Message Authentication, Reporting & Conformance (DMARC) will help to ensure that the sender of the message is genuine, by performing checks to make sure that the sender of the message is authorized to send messages from that domain.
Most anti-phishing solutions incorporate an anti-virus component that scans all incoming attachments for malware and malicious code, but cybercriminals are using sophisticated methods to evade detection by AV solutions. Files may include malicious code that is hard to detect. A sandbox is therefore required to execute suspicious attachments in a safe environment where they can be monitored for malicious activity. By testing attachments in the sandbox, malicious files can be identified and more genuine emails and attachments will arrive in inboxes.
SpamTitan incorporates these features and more. Together they help to ensure a catch rate in excess of 99.9%, with a low false positive rate of 0.03%. With SpamTitan in place, you will be well protected against phishing attacks such as the latest CAPTCHA scam.
Hotels in America are being targeted by cybercriminals in a campaign spreading a remote access Trojan (RAT) called NetWiredRC. The RAT is delivered via malicious emails targeting financial staff in hotels in North America.
The campaign uses a typical lure to get recipients to open the attached file. The message claims there are invoices outstanding and the recipient is asked to validate payment. The invoices are included in a zip file attached to the email.
If the file is extracted and the executable is launched, the Trojan will be downloaded by a PowerShell script. The Trojan achieves persistence by loading itself into the startup folder and will run each time the computer boots. The malware gives the attacker full control over an infected computer. Files can be uploaded and downloaded, further malware variants can be installed, keystrokes can be logged, and credentials can be stolen.
The ultimate aim of the threat actors behind this campaign is not known, although most cyberattacks on hotels are conducted to gain access to guest databases and payment systems. If malware can be loaded onto POS systems, card details can be skimmed when guests pay for their rooms. It can be months before hotels discover their systems have been breached, by which time the card details of tens of thousands of guests may have been stolen. Hutton Hotel in Nashville, TN, discovered in 2016 that its POS system had been infected with malware for three years.
There have been several recent cases of cyberattacks on hotels resulting in guest databases being stolen and sold on darknet marketplaces. The data breach at Marriott resulted in the theft of 339 million records and Huazhu Hotels Group in China experienced a breach of 130 million records.
Data breaches can prove incredibly costly. The cost of the data breach at Marriott could well reach $200 million, but even smaller data breaches can prove costly to resolve and can cause serious damage to a hotel’s reputation.
The latest spam campaign shows just how easy it is to gain a foothold in a network that ultimately leads to a 3-year data breach or the theft of more than 300 records: The opening of an attachment by a busy employee.
Hotels can improve their defenses by implementing cybersecurity solutions that block the threats at source. SpamTitan protects businesses by securing the email system and preventing malicious messages from reaching end users’ inboxes. WebTitan is an advanced web filtering solution that allows hotels to block malware downloads and carefully control the websites that can be accessed by staff and guests.

New figures have been released by the U.S. Financial Crimes Enforcement Network (FinCEN) on 2018 Business Email Compromise attacks. The latest FinCEN report highlighted the pervasiveness of the threat and potential for the attacks to result in serious financial harm.
Business Email Compromise (BEC) attacks are concerned with gaining access to a business email account and using that account to send messages to other individuals in an organization and business contacts. While compromised email accounts can be used for a variety of purposes, with BEC the primary goal is usually to convince an employee to make a fraudulent wire transfer or send sensitive information such as employee W-2 Forms.
Social engineering techniques are used to obtain the credentials of a high-level executive and convince an employee to make a fraudulent transfer. While at face value these scams are simplistic – they involve sending an email that requests a bank transfer be made – the scams are often highly sophisticated.
More than $300 Million a Month Was Lost to 2018 Business Email Compromise Attacks
The FinCEN report shows why these attacks are worth the effort. The average fraudulent transaction value in 2018 was $125,439 and $310 million per month was lost to BEC scams in 2018.
FinCEN received approximately 1,100 suspicious activity reports in 2018 that were attributed to BEC scams. It should be taken into consideration that many businesses are not obliged to report security breaches such as BEC scams, so the total losses will be considerably higher.
BEC attacks are also being conducted far more frequently and losses to the scams have skyrocketed. The 2016 FinCEN report indicates at least $110 million was lost to BEC scams. Losses to BEC scams have increased by 172% increase in just two years.
There has been a marked change in BEC scam tactics over the last two years, which has helped to increase the dollar amount of each fraudulent transaction.
As previously mentioned, the scams involve compromising an email account, which was commonly the email account of the CEO or CFO. The email accounts were used to send wire transfer requests and the average transaction value was $50,272. The 2018 figures show that there has been a shift from attacks that impersonate the CEO to attacks impersonating contractors and other vendors.
If a vendor’s email account is compromised, fake invoices can be sent to all companies that the vendor works for. Further, the typical amount of a vendor invoice is substantially higher than the transfer amounts typically requested by CEOs.
FinCEN’s figures show the average fake invoice transaction value was $125,439 for fake invoices from contractors, which is $75,167 more than the typical CEO email request.
FinCEN’s 2017 figures indicate 33% of BEC attacks involved impersonation of the CEO, but the percentage had fallen to just 12% in 2018. 39% of all BEC attacks in 2018 involved the impersonation of an outside entity such as a business associate, contractor, or vendor.
How to Improve Defenses Against BEC Attacks
With attacks increasing and losses spiraling, businesses need to take steps to reduce risk by improving email security and providing further training to employees. Employees should be made aware of the risk of BEC attacks, told about the latest threats, and should be taught how to identify a scam email. Policies should also be developed and implemented which require verification of all emailed transfer requests and bank account changes.
Training and policies will help to create a strong last line of defense, but the primary goal should be blocking the scam emails at the email gateway to ensure end users are not tested. That requires a powerful anti-spam and anti-phishing solution such as SpamTitan. SpamTitan blocks more than 99.97% of all spam and malicious emails to keep business inboxes threat free.

Two new Office 365 phishing scams have been detected in the past few days. One scam uses a fake Office 365 site to deliver the Trickbot Trojan and the other is a spear phishing campaign targeting Office 365 administrators to capture their credentials.
The Trickbot campaign uses a realistic domain – get.office365.live – that has all the typical elements of a genuine Microsoft website, including links to Microsoft resources. The website, identified by MalwareHunterTeam, detects the visitor’s browser and displays a popup within a few seconds of landing on the website.
A different warning is displayed for Firefox and Chrome users, with the associated logos. The warning comes from either the Chrome or Firefox Update Center. The message states that the user has an older version of the browser, which may cause incorrect site mapping, loss of all stored and personal data, and browser errors. An update button is supplied to download the browser update.
If the update button is clicked, it triggers the download of an executable file called upd365_58v01.exe. If that executable is run, the Trickbot Trojan will be downloaded and inserted into a svchost.exe process. That makes it harder for the user to detect the information stealer through Task Manager.
The Trickbot Trojan has several capabilities. It is a banking Trojan that can intercept banking credentials using webinjects. It also contains a password grabbing module which steals saved login credentials, autofill information, browsing history, and Bitcoin wallets. The malware also serves as a downloader for other malware variants and a module also been developed for propagation which includes the EternalBlue exploit.
Once installed, the malware stays in continuous contact with its C2. Due to the obfuscation methods used, the infection is unlikely to be detected by an end user, but the network admin may notice unusual traffic or attempts to connect to blacklisted domains.
This is a professional campaign that is likely to fool many end users. It is currently unclear whether traffic is being directed to the site through malvertising redirects or phishing emails.
Office 365 Admins Targeted
A phishing campaign has been detected which is targeting Office 365 administrators. Fake browser warnings are used to trick admins into disclosing their login credentials.
Emails have been constructed using the Microsoft and Office 365 logos which contain a warning about an aspect of Office 365 which requires the admin’s immediate attention. One message warns the admin about a mail redirect on an Office 365 inbox which indicates there has been an account compromise. Another advises the admin that the company’s Office 365 licenses have expired.
The emails contain a link for the admin to use to login to their Office 365 account to address the problem. The user will be directed to a webpage on the windows.net domain which has a valid certificate from Microsoft. The Microsoft login box is identical to that used on the Microsoft site.
Most admins will be vigilant and wary of warnings such as these. Even if the links are clicked, admins are likely to check the domain to make sure it is genuine. However, these scams are conducted because they do work. Some admins will be fooled and will disclose their credentials.
Admin credentials are highly valuable as they allow an attacker to create new office 365 accounts, access other user’s mailboxes, and send phishing emails from other accounts on the domain. These targeted attacks on admins are becoming more common due to the high value of the accounts and the range of attacks they allow a hacker to perform.
There is no single cybersecurity solution that will provide total protection from phishing attacks. What is needed is a defense in depth approach. End users should be provided with ongoing security awareness training to ensure they are aware of the most common threats and know how to identify potential scams. Phishing simulations are useful for gauging how effective training has been.
However, the priority must be to block these attacks and prevent end users from being tested. An advanced spam filter such as SpamTitan blocks more than 99.97% of spam and phishing emails. SpamTitan scans all incoming messages for malware and uses dual anti-virus engines for greater accuracy. A sandboxing feature has also now been added to allow the safe execution and analysis of suspicious email attachments.
WebTitan serves as an additional security layer that prevents end users from visiting malicious websites. The DNS filter can be used to exercise control over the types of websites that can be visited by employees and blocks all attempts to visit blacklisted websites, such as those that have been used for malware distribution, scams, or phishing.

New Office 365 Phishing Scams Detected FAQ
Will a spam filter block all spam and phishing emails?
No spam filter will be 100% effective, 100% of the time, which is why it is important to implement layered defenses. Many spam filters block around 99% of spam. SpamTitan is an advanced spam filter that has been independently verified as blocking 99.97% of spam email with a low false positive rate of just 0.03%.
How does email content filtering work?
Once initial checks have been performed to identify malware and emails from known spam sources, message content filtering takes place. Email content is analyzed, and each email is assigned a spam score based on phrases, keywords, images, and hyperlinks. A threshold is set and if that score is reached, the message will be rejected or quarantined.
What is greylisting and why is it important?
Greylisting is an important spam filtering mechanism for detecting new sources of spam. Greylisting initially rejects an email and requests the message is resent. Since email servers being used for spamming are busy sending huge volumes of messages, they do not respond to these requests or there is a significant delay. The delay is a good indicator that the message is spam.
Why should I scan outbound emails?
Outbound scanning is important for several reasons. By scanning outbound emails, email account compromises can be detected quickly to block business email compromise attacks. Attempts to use internal email accounts for sending malware and spam will be blocked, and tags can be applied to certain data types to identify attempted data theft by malicious insiders.
A serious outage has affected the spam filtering service, OnlyMyEmail, leaving customers without spam protection for several days.
The spam filtering service, also known as MXDefender, suddenly stopped working on Thursday and customers have been left in the dark about what has happened. Many have taken to online forums and social media to find answers but have only found hundreds of other customers asking the same questions. Customers have not been able to submit support tickets, the website is down, and the phone lines have been jammed.
MSPs know all too well that their clients are vulnerable to attack while their spam filtering service is down. Without the filter in place, spam, phishing, and malware-laced emails can flood into inboxes. All it takes is for one employee to respond to one of those messages for a costly breach to occur.
Several MSPs on forum such as Spiceworks have expressed their frustration about the prolonged outage and have already had to move their clients to alternative service providers to ensure they are protected until the issues are resolved. Two large MSPs have already switched to SpamTitan as a result of the OnlyMyEmail outage.
TitanHQ has received many enquiries about SpamTitan since the OnlyMyEmail service went down, as customers seek an alternative solution to protect their inboxes from email threats and spam. Many have given up waiting for an answer from OnlyMyEmail.
If you are a managed service provider or business that has been affected by the outage, it is important to implement a replacement spam filtering solution as soon as possible. The failure to do so will leave you extremely vulnerable to attack.
TitanHQ has developed an award-winning anti-spam and anti-phishing solution that has been shown to block more than 99.9% of spam in independent tests.
The 2019 G2 Crowd Report on Email Security Gateways named SpamTitan the leader for customer satisfaction. 97% of users awarded the product 4 or 5 stars and 92% of users would recommend the product to others.
TitanHQ ranked top for quality of support with an overall score of 94% – 10% more than the average score for support. SpamTitan clearly outperformed products from likes of Cisco, Barracuda, Mimecast, and SolarWinds.

You may have heard of ransomware-as-a-service – where ransomware is rented for a cut of the profits generated – but now there are a growing number of hackers offering phishing-as-a-service.
Ransomware-as-a-service proved popular as it allowed people without the skill set to create their own ransomware to conduct attacks and take a share of the profits. Conducting phishing attacks is easier. It requires no knowledge of malware or ransomware. All that is required is a hosted web page that mimics a brand you want to target, a phishing kit, and an email account to send phishing emails far and wide.
There is still entry barrier to cross before it is possible to conduct phishing attacks. Phishing requires some knowledge and skill as a spoofed phishing web page must be created and emails crafted that will attract a click. The web page will also need to be hosted somewhere so a compromised domain will therefore be required.
Phishing-as-a-service provides all of that. To get started, you purchase one of several phishing templates based on what you are targeting – Office 365, SharePoint, OneDrive, Google, or DocuSign credentials for example. The phishing pages are sold complete with phishing kits loaded and one month’s hosting.
One group offering phishing-as-a-service guarantees the phishing page will be hosted for one month and includes a three-link backup. If one URL fails or is reported as a phishing website, a further two links can be provided on request followed by a further three after that.
Phishing-as-a-service takes all the time-consuming work out of starting a phishing campaign and allows phishing campaigns to be conducted by individuals with next to no specific skills. Once payment is made for the web page, all that is required is the ability to conduct a spam campaign. The service also comes with the option of purchasing lists of email addresses for the country of choice. All that is required to conduct a phishing campaign is payment ($30+) for phishing-as-a-service and a convincing phishing email.
With the entry barrier being substantially lowered, phishing attacks are likely to become much more frequent. It is therefore essential for businesses of all sizes to take steps to improve protections and reduce susceptibility to phishing attacks.
If you are defending against any attack it pays to know your enemy. It is therefore essential for all employees with an email account to be provided with security awareness training and be taught how to recognize a phishing attack.
It is also important to implement cybersecurity solutions that help to ensure your last line of defense will not be tested. You should have an advanced anti-spam solution in place to block the vast majority of phishing threats. If you use Office 365 for your business email, a third-party anti-spam solution will provide a greater level of protection.
An additional protection against phishing attacks that is often overlooked is a DNS filter or web filter. A web filter gives organizations control over what their employees can do online and which websites they can visit. Any website that has been reported as malicious is automatically blocked using blacklists and webpages are scanned in real-time and blocked if malicious. If a phishing email reaches an inbox and attracts a click, the attempt to access the phishing website can be blocked.
If you want to improve your email and web security posture or you are looking for better value cybersecurity solutions, TitanHQ can help. Contact TitanHQ today to discuss your email and web security requirements and you will be advised on the best solutions to meet your needs.

DMARC email authentication is an important element of phishing defenses, but what is DMARC email authentication, what does it do, and how does it protect against email impersonation attacks?
There is some confusion about what DMARC email authentication is and what it can do. In this post we explain in clear English what DMARC means and why it should be part of your anti-phishing defenses.
DMARC is short for Domain-based Message Authentication, Reporting, and Conformance. Its purpose is to make it harder for threat actors to conduct phishing attacks that spoof brands and get those messages delivered to inboxes.
With DMARC, organizations can create a record of who is authorized to send emails from their domain. This helps to prevent misuse of a company brand in phishing campaigns.
If DMARC is implemented on email, a business can have all incoming emails checked against DMARC records and any email that fails the check can be subjected to certain actions.
The message can be delivered as normal with a warning and the email will be included in a report of emails that failed the check. The message could automatically be sent to quarantine for manual approval before delivery is made. Alternatively, the message could be rejected or subjected to a custom policy. An organization can select the best policy to adopt based on their level of risk tolerance.
DMARC will not stop all phishing emails from being delivered, but it is an important measure to implement to stop email spoofing and reduce the number of phishing emails that reach inboxes.
DMARC is just one of several rules that are used to determine whether emails are genuine and should be delivered or if the messages have been sent from an unauthorized user.
Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and DNS records are also used to determine whether the email server being used is authorized to send emails for the organization.
The SPF record indicates which email servers are authorized to send mail on behalf of a domain. This would be the organization itself and any third parties, such as marketing companies. The SPF record is a DNS TXT record that includes IP addresses and hostnames that are allowed to send emails from a particular domain. The SPF record is the first thing checked by DMARC rules.
DKIM is more advanced and uses a TXT record and asymmetric public-private key encryption. With DMARC enabled, the signature is encrypted with the public key and the key is published on DNS servers. The domain’s private key is then used at the recipient’s email server for verification.
If DKIM is enabled, the public key-encrypted signature is compared with the message that is decrypted using a newly generated key to confirm that the message has not been altered. DKIM also confirms that the sender is from the listed domain and that the sender has not been spoofed.
DMARC offers a much greater level of protection than SPF and is more dependable, so both should be implemented. TitanHQ is happy to announce that both SPF and DMARC are incorporated into SpamTitan to better protect users from email spoofing attacks.

A new strain of ransomware has been identified which has been used in multiple attacks over the past few weeks.
All of the attack vectors used to distribute the ransomware are not yet known, but samples of the ransomware have been distributed via a spam email campaign.
The spam email campaign uses a tried and test format to deliver the ransomware payload. A Word document called Info_BSV_2019.docm is attached to emails with requests that the recipient open the document. In order for the contents to be displayed, the user is told they must enable macros. Enabling macros will launch code that downloads an executable file, which is renamed LooCipher.exe and is executed.
The ransomware will encrypt a standard range of file types, but instead of deleting the original files, they are retained as zero-byte files. Encrypted files are given the extension .lcphr.
The ransomware creates a file on the Windows Desktop called c2056.ini, which includes the unique ID number of the computer, the time limit for paying the ransom, and the Bitcoin wallet address for payment. The ransom note warns that deletion of the ini file will prevent file recovery.
Users are given 5 days to pay the ransom or the key to unlock files will be permanently deleted. The ransom is €300 ($330) in Bitcoin per device. No option is provided to test to see whether a file can be decrypted.
LooCipher ransomware may not be particularly polished, but it has already claimed several victims. Recovery will depend on an organization’s ability to restore files from backups. It is not clear whether the attackers hold valid keys to decrypt encrypted files.
Ransomware attacks have been increasing following a decline in popularity of ransomware with hackers in 2018. There have been high profile attacks on U.S. cities and ransoms and hundreds of thousands of dollars have been paid in ransoms. Ransomware attacks on healthcare organizations have increased, and several new strains of ransomware have emerged.
Recently the Department of Homeland Security warned of the risk of wiper malware attacks by Iranian threat actors, as tensions between the United States and Iran continue to increase.
These malware threats may be delivered by a variety of different methods, but spam email is the delivery vector of choice. Protecting against these malware threats requires an advanced spam filtering solution capable of precision control over incoming email and the ability to scan messages and analyze attachments for malicious code.
SpamTitan uses twin AV engines to identify known malware and a sandbox to analyze suspicious attachments to identify malicious actions and provides superior protection against malware, ransomware, viruses, botnets, and phishing attacks.
To find out more about how you can improve email security with SpamTitan, contact the TitanHQ team today.
Tension is rising between the United States and Iran following the downing of a U.S. Global Hawk surveillance drone close to the Strait of Hormuz and the recent mine attacks.
Less visual are the attacks on IT systems. The Washington post recently reported that the United States had conducted a successful cyberattack on the Islamic Revolutionary Guard Corps, part of the Iranian military, which is believed to have been involved in the mine attacks.
Iranian-affiliated hacking groups have conducted cyberattacks on U.S. industries and government agencies and those attacks are increasing in frequency. So much so that the Director of the U.S. Cybersecurity and Infrastructure Security Agency (CISA), Chris Krebs, sent out a warning on Twitter about the increased risk of attack.
“CISA is aware of a recent rise in malicious cyber activity directed at United States industries and government agencies by Iranian regime actors and proxies,” said Krebs.
Threat actors affiliated with Iran have been using wiper malware in targeted attacks on businesses, government agencies, industries, and infrastructure. Whereas ransomware encrypts files with the aim of receiving a ransom payment, the purpose of wiper malware is to permanently destroy data and wipe systems clean.
Wiper malware has previously been used in major attacks, some targeted, others less so. In 2012, Saudi Aramco, a Saudi Arabian oil firm, was attacked with a wiper malware variant called Shamoon. The malware wiped tens of thousands of computers.
More recently were the NotPetya attacks. While initially thought to be ransomware, it was later discovered there was no mechanism for file recovery and the malware was a wiper. Some companies were hit hard. The shipping firm Maersk suffered losses of around $300 million due to NotPetya. Global losses are estimated to be between $4-8 billion.
Hackers working for the Iranian regime commonly gain access to computers and servers through the use of phishing, spear phishing, credential stuffing, and password spraying.
“What might start as an account compromise, where you think you might just lose data, can quickly become a situation where you’ve lost your whole network,” warned Krebs.
As with ransomware, recovery from a wiper malware attack is reliant on backups, except there is no safety net as a ransom cannot be paid to recover data. It is therefore essential that a working copy of all data is maintained, with one copy stored securely off-site on a non-networked, non-internet exposed device.
Even with a working copy of data, recovery can be time consuming and costly. It is therefore important to ensure that solutions are in place to block the main attack vectors.
A spam filtering solution with advanced anti-malware capabilities is therefore required to block email-based attacks. A web filtering solution can prevent users from visiting malicious websites or inadvertently downloading malware and employees should be provided with security awareness training to help them recognize potential threats.
Standard cybersecurity best practices should be adopted such as ensuring strong password policies are implemented and enforced, multi-factor authentication is implemented, all software is kept up to date and patched are applied promptly. IT departments should also ensure permissions are set to the rule of least privilege.
A phishing campaign targeting university employees has already claimed several victims and has seen many email accounts compromised.
Emails are tailored to the institution and use a range of social engineering tricks to convince employees to click a link in the email and enter their Office 365 login credentials to access online content. The credentials are captured and used to gain access to university email accounts.
Once credentials have been obtained, a treasure trove of sensitive data can be plundered. Emails and email attachments contain personally identifiable information of staff, students, and parents, which can be used to commit identity theft and other fraudulent acts. Proprietary information can be obtained, along with details of contacts. The compromised accounts can also be used to conduct further phishing attacks on the university and externally on business contacts and other educational institutions.
Campaigns convincing users to install malware can give the attackers full control of university computers and a foothold to move laterally throughout the network. Access to university email accounts and backdoors in university computers are sold on the dark web, along with a range of stolen and forged university documents.
The healthcare industry is heavily targeted by cybercriminals due to the high value of health data. Health data is versatile and can be used for a multitude of fraudulent purposes. It also has a long-life span and can be used for much longer than financial information. Cybercriminals are also now realizing the potential rewards from attacks on universities. Student data is similarly versatile, and the wealth of data stored in university email accounts provides plenty of opportunities for profit.
Oregon State University is the latest university to announce it is the victim of a phishing attack. The Office 365 email account of an employee was compromised, through which the attacker had access to the records of 636 students. The account was used to send phishing emails to other entities throughout the United States.
Graceland University in Iowa and Southern Missouri State University recently announced that several email accounts had been compromised in recent phishing attacks, which would have allowed access to be gained to sensitive information.
It is unclear whether this is a single campaign or part of a wave of separate attacks on universities. What is clear is the attacks are increasing, so universities should take steps to improve email and web security.
Employees are being targeted so it is important to ensure that staff members are taught email security best practices and are shown how to identify phishing emails.
Technological defenses can also be improved to prevent malicious messages from arriving in Office 365 inboxes. As an additional protection, a DNS filter can be used to prevent users from accessing phishing websites and other known malicious web pages.
TitanHQ has developed powerful anti-phishing and anti-malware solutions for universities that help them protect against email and web-based attacks.
SpamTitan is a powerful anti-spam solution that incorporates DMARC authentication and sandboxing to provide superior protection against impersonation and malware attacks for Office 365 users.
WebTitan is a DNS filtering solution that prevents users from accessing known malicious websites, such as those used for phishing and distributing malware.
To improve Office 365 phishing defenses and better protect your email accounts and networks from malware attacks, contact TitanHQ for further information on these two powerful cybersecurity solutions for educational institutions.

The TitanHQ team will be on hand at the conference to discuss your email and web security needs and will offer practical advice to help you better serve the needs of your customers and get the very most out of TitanHQ solutions.
Visitors to the TitanHQ stand (booth 23) will have the opportunity to learn about TitanHQ’s exclusive TitanShield Program for MSPs. Through the TitanShield program, members have access to SpamTitan email security and phishing protection; the WebTitan DNS filter; and the ArcTitan email archiving solution. Around 2,000 MSPs have already signed up to the program and are using TitanHQ solutions to protect their clients.
If you currently use Cisco Umbrella to provide web and malware protection, you may be paying far more for security than is necessary and could well be struggling with product support. Be sure to speak to the team about the savings from switching and the support provided by TitanHQ. A visit will also be useful for MSPs that are currently supporting Office 365, as the team will explain how spam, phishing and malware protection can be enhanced.
TitanHQ Executive Vice President-Strategic Alliances, Rocco Donnino, will be on the panel for the new, Datto Select Avendors event on Monday. The event runs from 3PM to 4PM and brings together experts from several select companies who will help solve some of the epic problems faced by MSPs today.

Shade ransomware was first identified by security researchers in 2014, when it was primarily being used in attacks on Russian businesses; however the threat actors behind this ransomware variant have broadened their horizons and attacks are now being conducted around the world. The United States is now the most attacked country followed by Japan, India, Thailand, and Canada. Russia has now fallen from top spot to seventh.
Shade ransomware, like many ransomware variants, is primarily spread via email. Emails are sent to businesses which appear at first glance to be invoices or bills. The emails contain links to websites hosting malicious files which are downloaded to the user’s device. A variant of this method uses a PDF attachment which contains a link inside which must be clicked to download a fake invoice or bill.
An analysis of the latest campaigns was recently conducted by Palo Alto Networks Unit 42 team. That analysis revealed the attackers are concentrating their attacks on high-tech companies, retailers, wholesalers, telecommunications, and educational institutions and the threat actors behind the campaigns have been highly active in 2019.
Since Shade ransomware is most commonly spread via spam email, to reduce the risk of an attack, businesses should implement an advanced email gateway solution that is capable of identifying and blocking the malspam emails that ultimately deliver Shade ransomware.
SpamTitan protects businesses from Shade ransomware and other email-based malware attacks. SpamTitan includes dual antivirus engines to detect malicious files attached to emails and scans the content of messages and subjects them to a Bayesian analysis and heuristics to identify signatures of spam and malicious messages.
The solution now incorporates a Bitdefender-powered sandbox feature which allows files to be opened in a safe and secure environment where they can be analyzed for malicious activity. The solution also allows users to block attachments commonly used to deliver malware, such as zip files and executable files such as .exe and .js.
These and other protection mechanisms help to ensure that only legitimate emails are delivered and malicious messages are prevented from being delivered to end users’ inboxes.
If you want to protect your business against ransomware and malware attacks, contact TitanHQ today to find out more about SpamTitan and take the first step towards improving your security posture.
SpamTitan, TitanHQ’s business email security solution, has been named leader in the Spring G2 Crowd Grid Report for Email Security Gateways.
G2 Crowd is a peer-to-peer review platform for business solutions. G2 Crowd aggregates user reviews of business software and the company’s quarterly G2 Crowd Grid Reports provide a definitive ranking of business software solutions.
The amalgamated reviews are read by more than 1.5 million site visitors each month, who use the reviews to inform software purchases. To ensure that only genuine reviews are included, each individual review is subjected to manual review.
The latest G2 Crowd Grid Report covers email security gateway solutions. Gateway solutions are comprehensive email security platforms that protect against email-based attacks such as phishing and malware. The email gateway is a weak point for many businesses and it is one that is often exploited by cybercriminals to gain access to business networks. A powerful and effective email gateway solution will prevent the vast majority of threats from reaching end users and will keep businesses protected.
To qualify for inclusion in the report, email gateway solutions needed to scan incoming mail to identify spam, malware, and viruses, securely encrypt communications, identify and block potentially malicious content, offer compliant storage through archiving capabilities, and allow whitelisting and blacklisting to control suspicious accounts.
For the report, 10 popular email security gateway solutions were assessed from Cisco, Barracuda, Barracuda Essentials, Proofpoint, Mimecast, Symantec, McAfee, Solarwinds MSP, MobileIron, and TitanHQ. Customers of all solutions were required to give the product a rating in four areas: Quality of support, ease of use, meets requirements and ease of administration.
