Spam software is a network security 101 basic protection that should be in place at every organization. Spam software filters out productivity-draining spam messages and prevents phishing emails and other email-based threats from being delivered to employees’ inboxes.
Research conducted by the intelligence software and anti-phishing training company PhishMe shows that 91% of cyberattacks start with a phishing email. Phishing emails aim to get the recipient to divulge sensitive information such as bank account information or login credentials. However, over the course of the past 12 months, cybercriminals have increasing used spam email to distribute ransomware. In Q3, 2016, PhishMe reported that 97% of phishing emails were being used to deliver ransomware or ransomware downloaders. Spam email is now the number one vector used to deliver malware and ransomware.
Spam email campaigns are also becoming more sophisticated and it is becoming much harder to distinguish spam from genuine emails. Many of the latest campaigns contain no spelling mistakes, are grammatically correct and use imagery from well-known brands with smart, professional layouts.
Cybercriminals are also using social engineering techniques to fool end users into clicking malicious links and opening infected email attachments. Without spam software to quarantine those emails, they will be delivered to inboxes and employees are likely to be fooled into taking the requested actions.
Fortunately, advanced spam solutions can now filter out more than 99% of spam emails, with SpamTitan preventing more than 99.9% of spam emails from being delivered. This category contains up to date information on spam software, new threats that are now blocked and advice for organizations on improving defenses against email threats.
This week, TitanHQ has rolled out two new features for its award-winning email security solution SpamTitan: Sandboxing and DMARC email authentication.
TitanHQ developed the technology behind its email security solution more than 20 years ago and over the past two decades SpamTitan has received many updates to improve features for end users and increase detection rates.
SpamTitan already blocks more than 99.9% of spam and malicious emails to prevent threats from reaching end users’ inboxes. The level of protection SpamTitan provides against email attacks has made it the gold standard in email security for the SMB market and managed service providers serving SMBs.
In order to provide even greater protection against increasingly sophisticated email threats, TitanHQ added a new sandboxing feature. The next-generation sandboxing feature, powered by Bitdefender, provides SpamTitan customers with a safe environment to run in-depth analyses of suspicious programs and files that have been delivered via email.
New SpamTitan Sandboxing Service
The sandbox is a powerful virtual environment totally separate from other systems. When programs are run in the sandbox, they behave as they would on an ordinary endpoint and can be assessed for suspicious behavior and malicious actions without causing harm.
Prior to being sent to the sandbox, files are first analyzed using SpamTitan’s anti-malware technologies. Only files that require further analysis make it to the sandbox where they are safely detonated. Tactics used by malware to evade detection and avoid analysis are logged and flagged. Purpose-built, advanced machine learning algorithms they assess the files and check their actions against an extensive array of known threats from a range on online repositories in a matter of minutes.
If the file is confirmed as benign, it can be released. If the file is determined to be malicious, the sandboxing service automatically sends a report to the Bitdefender’s Global Protective Network and all further instances of the threat will then be blocked globally to ensure the file does not need to be analysed again.
The sandbox provides advanced protection against zero-day exploits, polymorphic threats, APTs, malicious URLs, new malware samples that have yet to be identified as malicious, and new threats that have been developed for undetectable targeted attacks.
Incorporation of this feature into SpamTitan gives customers advanced emulation-based malware analysis capabilities without having to purchase a separate sandboxing solution and ensures customers are protected against rapidly evolving advanced threats.
DMARC Email Authentication Added to SpamTitan
Email spoofing is the term given to the use of a forged sender address. Email spoofing is used to increase the likelihood of an email being delivered and opened by an end user. The email address of a known contact, well known company, or government organization is usually spoofed to abuse trust in that individual, brand, or organization.
DMARC authentication is now essential for all businesses and is a powerful control to prevent spoofing attacks. DMARC is used to check email headers to provide further information about the true sender of an email. Through DMARC, the message is authenticated as having been sent from the organization that owns the domain. If authentication fails, the message is rejected.
While SPF provides a certain degree of protection against email spoofing, DMARC is far more dependable. SpamTitan now incorporates DMARC authentication to provide even greater protection against email spoofing attacks.
Both of these new features have been added in the latest update to SpamTitan and are available to users at no extra cost.
“We have listened to requests from customers to have new features added to SpamTitan, and by far the most requested improvements are anti-spoofing technology and sandboxing,” said Ronan Kavanagh, CEO, TitanHQ. “I’m delighted to say that both of these new features have now been added to provide enhanced security for customers at no extra cost.”
During tax season, tax phishing scams are rife. If cybercriminals can steal personal information such as the information contained on W2 forms, they can use the information to file fraudulent tax returns. Each set of credentials can net cybercriminals thousands of dollars. Attacks on businesses can be even more profitable. If an attack results in the theft of the tax credentials of a company’s entire workforce, hundreds of fraudulent tax returns can be filed.
The IRS works hard to combat fraud, but even so, many of these attacks are successful and fraudulent tax refunds are issued. This week, as part of its efforts to combat tax fraud, the IRS has launched its 2019 Dirty Dozen campaign. The campaign raises awareness of the threat of tax fraud and encourages taxpayers, businesses, and tax professionals to be vigilant.
The campaign features 12 common tax scams that attempt to obtain personal information or access to systems that contain such information. The campaign will see a different scam highlighted for 12 consecutive days. The campaign was launched on March 4 with the biggest threat in tax season: Tax phishing scams.
Common Tax Phishing Scams
Tax phishing scams are constantly evolving and each year several new tax phishing scams are identified. The most common scams and attacks are:
Business Email Compromise (BEC) attacks
Business Email Spoofing (BES) attacks
Email impersonation attacks
BEC attacks involve the use of a genuine business email account to send messages to employees requesting the W2 form information of employees, changes to business account information, requests to reroute direct deposits and make fraudulent wire transfers. The attackers often gain access to a high-level executive’s email account through a spear phishing campaign. BEC is one of the most common business tax phishing scams.
BES attacks are similar, except that no email account has been compromised. The email address of an executive or other employee is spoofed so that emails appears to have been sent from within an organization.
Email impersonation attacks are common during tax season. Scammers impersonate the IRS and use a variety of lures to obtain personal information. Common lures are threats of legal action or fines for outstanding taxes and offers of tax refunds. They often direct users to a website where they are required to enter their personal information. These phishing webpages are also linked to on social media websites. The clients of tax professionals may also be impersonated. Emails often request changes be made to direct deposit accounts or contain requests for sensitive information.
Malware is often used to gain access to the computers of tax professionals, and employees in the payroll and HR departments. Keyloggers are commonly used as they allow the attackers to steal login credentials. Malware can also transfer files containing sensitive information to the attackers’ servers. Malware is often installed via scripts in email attachments – malicious macros for instance – or via drive-by downloads from malicious websites.
New Phishing Scam Targeting Tax Professionals
One of the new tax phishing scams to emerge this year targets tax professionals. First the attackers gain access to tax professionals’ computers, either through spear phishing campaigns or by installing malware. Client tax information is then stolen and fraudulent tax returns are files in the clients’ names. When the IRS processes the refunds, payments are sent to taxpayers’ bank accounts. Those taxpayers then receive a call or an email demanding the return of the funds which have been paid in error. The attackers claim to be from a debt collection agency used by the IRS or the IRS itself.
Don’t Become a Victim of a Tax Phishing Scam
Many taxpayers and businesses fall victim to tax phishing scams each year, especially during tax season when attacks increase; however, by taking some simple steps and being vigilant it is possible to identify scams and keep financial and personal data secure.
Any email, text, or telephone call that requests personal/tax information should be treated as a potential scam. If an email or text message is received that claims to be from the IRS demanding payment of outstanding taxes, an offer of a tax refund, or a threat of legal action, bear in mind that the IRS does not initiate contact via email or text message asking for personal information. If such a message is received, forward the email to firstname.lastname@example.org and contact the IRS or check your online tax account to find out if there is a genuine problem. Never use the contact information or links in an email and do not open an email attachment in an email that appears to have been sent by the IRS.
Businesses can include information about tax phishing scams in their security awareness training sessions, but departments that are likely to be targeted by cybercriminals – payroll, human resources, finance and accounting Etc.) should receive specific training ahead off the start of tax season. Sending monthly reminders about phishing attacks and other tax scams each month via email is also a good best practice.
Since most attacks start with a phishing email, businesses should ensure that they have an advanced spam filtering solution in place to block phishing and other emails at the gateway before they can be delivered to end users. SpamTitan is an ideal anti-spam solution for businesses and tax professionals to protect against tax phishing scams. The solution blocks more than 99.9% of spam and phishing emails and includes outbound email scanning to ensure that compromised email accounts cannot be used for spamming.
To protect against internet phishing scams, a web filtering solution is ideal. WebTitan prevents end users from visiting phishing websites, including blocking visits to malicious websites via hyperlinks in scam emails. The solution also blocks drive-by malware downloads and other web-based threats.
If you are a tax professional or you run a business and are unhappy with your current anti-spam or web filtering solution provider, or you have yet to implement either of these solutions, give the TitanHQ team a call today for further information on how these solutions can protect your business, details of pricing, and to book a product demonstration.
Spoofed email phishing scams can be hard for end users to identify. The scams involve sending a phishing email to a user and making the email appear as if it has been sent by a known individual. This could be a known contact such as a supplier, a work colleague, a friend or family member, or a well-known company.
These phishing campaigns abuse trust in the sender and they are highly effective. Many end users are warned never to click on links in emails or open email attachments in messages from unknown senders, but when the sender is known, many users feel that the email is safe.
One of the most effective spoofed email phishing scams involves impersonation of the CEO or a high-level executive such as the CFO. This type of scam is often referred to as a business email compromise scam or BEC attack. A message is sent to an employee in the accounts department requesting an urgent wire transfer be made along with the account details. The attacker may first start an email conversation with the target before the request is made. No employee wants to refuse a direct request from the CEO, so the requested action is often taken.
Over the past few months, sextortion scams have grown in popularity with cybercriminals. Sextortion scams are those which threaten to oust the victim unless a payment is made. This could be disclosing the user’s internet browsing habits (dating sites, adult sites) to a spouse, work colleagues, and family members. There were many of these scams launched following the hacking of the Ashley Madison website when details of users of the site were dumped online.
Several sextortion scams have been detected in the past few months which claim that the sender (a hacker) has gained access to the user’s computer and installed malware that provided access to the webcam, microphone, and internet browsing history. The email message informs the recipient that they have been recorded while viewing adult websites and a video of them has been spliced with the content they were viewing at the time. The attacker threatens to send the video to every one of the user’s contacts on email and social media accounts.
Two recent sextortion campaigns have been detected that spoof the users own email address, so the email appears to have been sent from their own email account. This tactic backs up the claim that the attacker has full control of the user’s device and access to their email contacts. The reality is the email header has just been spoofed. Additionally, the user’s password is included in the message, which has been obtained from a past data breach. The password may not be current, but it may be recognized.
A check of the bitcoin wallet address included in the emails for the blackmail payment shows these scam emails have been highly effective and several victims have paid up to avoid being outed. One campaign netted the attacker $100,000 in one week, another saw payments made totaling $250,000.
These spoofed email phishing scams are not difficult to block, yet many businesses are vulnerable to these types of attacks. Security awareness training for employees is a must. If employees are not taught how to check for spoofed email phishing scams, they are unlikely to recognize threats for what they are. Even so, it is difficult for an average employee to identify every possible phishing attempt, as phishing email simulations show.
What is needed is an advanced spam filtering solution that can detect spoofed email phishing attacks and block the malicious emails at source to prevent messages from being delivered to inboxes. SpamTitan Cloud, for instance, blocks more than 99.9% of spam and phishing emails to keep businesses protected.
If you want to keep your business protected and prevent these all to common spoofed email phishing attacks, give the TitanHQ team a call. A member of the team will be happy to talk about the product, the best set up for your organization, and can arrange to give you a full product demonstration and set you up for a free trial.
It doesn’t take long after the release of a patch for hackers to take advantage, especially when the vulnerability potentially impacts 500 million users. It is therefore not surprising that at least one hacker is taking advantage of a recently disclosed WinRAR vulnerability.
Oftentimes, vulnerabilities are found in certain versions of software, but this vulnerability affects all WinRAR users and dates back 19 years. The WinRAR vulnerability was identified by researchers at Check Point. WinRAR was alerted and confirmed the vulnerability existed, and promptly issued an updated version of the file compression tool with the vulnerability removed. Details of the vulnerability were disclosed in a Check Point blog post on February 20, 2019.
The WinRAR vulnerability in question was present in a third-party DLL file which was included in WinRAR to allow ACE archive files to be uncompressed. The researchers found that by renaming a .rar archive to make it appear that the compressed file was an ACE archive, it was possible to extract a malicious file into the startup folder unbeknown to the user. That file would then run on boot, potentially giving an attacker full control of the device. The malicious file would continue to load on startup until discovered and removed.
All an attacker would need to do to exploit the WinRAR vulnerability is to convince a user to open a specially crafted .rar archive file attached to an email. Compressed files are often used in malspam campaigns to hide malicious executable files. Since .rar and .zip files are commonly used by businesses to send large files via email, they are likely to be recognized and may be opened by end users.
In this case, if the archive contents are extracted, the user would likely be unaware that anything untoward had happened, as the executable is loaded into the startup folder without giving any indication the file has been extracted. Due to the location of extraction, no further actions are required by the user.
In this case, the executable installs a backdoor, although only if the user has User Account Control (UAC) disabled. That said, this is unlikely to be the only campaign exploiting the WinRAR vulnerability. Other threat actors may develop a way to exploit the vulnerability for all users that have yet to update to the latest WinRAR version.
Many users will have WinRAR installed on their computer but will rarely use the program, so may not be aware that there is an update available. It is possible that a large percentage of users with the program installed have yet to update to the latest version and are vulnerable to attack.
This campaign illustrates just how important it is to patch promptly. As soon as a patch is released for a popular software program it is only a matter of time before that vulnerability is exploited, even just a few days.
Patching all devices in use in an organization can take time. It is therefore important to make sure that all employees receive security awareness training and are taught email security best practices and how to identify potentially malicious emails.
Unfortunately, social engineering techniques can be highly convincing, and many users may be fooled into opening email attachments, especially when the attacker spoofs the sender’s email address and the email appears to come from a known individual. It is therefore essential to have an advanced spam filtering solution in place that is capable of detecting malicious attachments at source, including malicious files hidden inside compressed files, and stop the messages from being delivered to inboxes.

The 2019 Cybersecurity Survey conducted by the Healthcare Information and Management Systems Society (HIMSS) has highlighted healthcare email security weaknesses and the seriousness of the threat of phishing attacks.
HIMSS conducts the survey each year to identify attack trends, security weaknesses, and areas where healthcare organizations need to improve their cybersecurity defenses. This year’s survey confirmed that phishing remains the number one threat faced by healthcare organizations and the extent that email is involved in healthcare data breaches.
This year’s study was conducted on 166 healthcare IT leaders between November and December 2018. Respondents were asked questions about data breaches and security incidents they had experienced in the past 12 months, the causes of those breaches, and other cybersecurity matters.
Phishing attacks are pervasive in healthcare and a universal problem for healthcare providers and health plans of all sizes. 69% of significant security incidents at hospitals in the past 12 months used email as the initial point of compromise. Overall, across all healthcare organizations, email was involved in 59% of significant security incidents.
The email incidents include phishing attacks, spear phishing, whaling, business email compromise, and other email impersonation attacks. Those attacks resulted in network breaches, data theft, email account compromises, malware infections, and fraudulent wire transfers.
When asked about the categories of threat actors behind the attacks, 28% named ‘online scam artists’ and 20% negligence by insiders. Online scam artists include phishers who send hyperlinks to malicious websites via email. It was a similar story the previous year when the survey was last conducted.
Given the number of email-related breaches it is clear that anti-phishing defenses in healthcare need to be improved. HIPAA requires all healthcare employees to receive security awareness training, part of which should include training on how to identify phishing attacks. While this is a requirement for compliance, a significant percentage (18%) of healthcare organizations do not take this further and are not conducting phishing simulations, even though they have been shown to improve resilience against phishing attacks by reinforcing training and identifying weaknesses in training programs.
The continued use of out of date and unsupported software was also a major concern. Software such as Windows Server and Windows XP are still extensively used in healthcare, despite the number of vulnerabilities they contain. 69% of respondents admitted still using legacy software on at least some machines. When end users visit websites containing exploit kits, vulnerabilities on those devices can easily be exploited to download malware.
It may take some time to phase out those legacy systems, but improving healthcare email security is a quick and easy win. HIMSS recommends improving training for all employees on the threat from phishing with the aim of decreasing click rates on phishing emails. That is best achieved through training, phishing simulations, and better monitoring of responses to phishing emails to identify repeat offenders.
At TitanHQ, we can offer two further solutions to improve healthcare email security. The first is an advanced spam filtering solution that blocks phishing emails and prevents them from being delivered to inboxes. The second is a solution that prevents employees from visiting phishing and other malicious websites such as online scams.
SpamTitan is an advanced anti-phishing solution that scans all incoming emails using a wide range of methods to identify malicious messages. The solution has a catch rate in excess of 99.9% with a false positive rate of just 0.03%. The solution also scans outbound messages for spam signatures to help identify compromised email accounts.
WebTitan Cloud is a cloud-based web filtering solution that blocks attempts by employees to visit malicious websites, either through web surfing or responses to phishing emails. Should an employee click on a link to a known malicious site, the action will be blocked before any harm is caused. WebTitan also scans websites for malicious content to identify and block previously known phishing websites and other online scams. Alongside robust security awareness training programs, these two solutions can help to significantly improve healthcare email security.

A new Office 365 phishing scam has been detected that attempts to get users to part with their Office 365 credentials with a request for collaboration via SharePoint.
The campaign was first detected in the summer of 2018 by researchers at cybersecurity firm Avanan. The Office 365 phishing scam is ongoing and has proven to be highly effective. According to Kaspersky Lab, the phishing campaign has been used in targeted attacks on at least 10% of companies that use Office 365.
This Office 365 phishing scam abuses trust in SharePoint services that are often used by employees. An email is sent to an Office 365 user that contains a link to a document stored in OneDrive for Business. In contrast to many phishing campaigns that spoof links and fool users into visiting a website other than the one indicated by the link text, this link actually does direct the user to an access request document on OneDrive.
A link in the document then directs users to a third-party website where they are presented with a Microsoft Office 365 login page that is a perfect copy of the official Office 365 login page. If login credentials are entered, they are given to the scammers. Once obtained, it is possible for the scammers to gain access to the Office 365 account of the user, including email and cloud storage.
The email accounts can be used for further phishing campaigns on the user’s contacts. Since those messages come from within the organization, they are more likely to be trusted. Email accounts can also contain a wealth of sensitive information which is of great value to competitors. In healthcare, email accounts can contain patient information, including data that can be used to steal identities. The attackers can also use the compromised credentials to spread malware. Employees may know not to open attachments from unknown individuals, but when they are sent from a colleague, they are more likely to be opened.
Businesses that use Microsoft’s Advanced Threat Protection (APT) service may mistakenly believe they are protected from phishing attacks such as this. However, since the links in the email are genuine OneDrive links, they are not identified as malicious. It is only the link in those documents that is malicious, but once the document is opened, Microsoft’s APT protection has already been bypassed.
Finding Office 365 users is not difficult. According to a 2017 Spiceworks survey, 83% of enterprises use Office 365 and figures from 2018 suggest 56% of organizations globally have adopted Office 365. However, a basic check can easily identify Office 365 users as it is broadcast on public DNS MX records. If one user can be found in an organization, it is highly likely that every other user will be using Office 365.
Businesses can take steps to avoid Office 365 phishing scams such as this.
Ensure that all employees are made aware of the threat from phishing, and specifically this Office 365 phishing scam. They should be told to exercise caution with offers to collaborate that have not been preceded by a conversation.
Conduct phishing email simulations to test defenses against phishing and identify individuals that require further security awareness training.
Activate multifactor authentication to prevent stolen credentials from being used to access Office 365 accounts from unknown locations/devices.
Change from APT anti-phishing controls to a third-party spam filter such as SpamTitan. This will not only improve catch rates, it will also not broadcast that the organization uses Office 365.
Use an endpoint protection solution that is capable of detecting phishing attacks.
Implement a web filter to prevent users from visiting known phishing websites and other malicious web pages.
The French engineering firm Altran Technologies has been grappling with a malware infection that hit the firm on January 24, 2019.
Immediately following the malware attack, Altran shut down its network and applications to prevent the spread of the infection and to protect its clients. Technical and computer forensics experts are now assisting with the investigation. The Altran cyberattack has affected operations in some European countries and the firm is currently working through its recovery plan.
A public announcement has been made about the attack although the malware involved has not been officially confirmed. Some cybersecurity experts believe the attack involved a new ransomware variant named LockerGoga which emerged in the past few days.
LockerGoga ransomware was first identified on January 24 in Romania and subsequently in the Netherlands. It was named by MalwareHunterTeam, based on the path used for compiling the source code into an executable.
LockerGoga ransomware does not appear to be a particularly sophisticated malware variant. Security researcher Valthek, who analyzed the malware, claimed the code was ‘sloppy’, the encryption process was slow, and little effort appears to have been made to evade detection. The ransomware appends encrypted files with the .locked file extension.
The ransomware note suggests that companies are being targeted although it is currently unclear how the ransomware is being distributed.
LockerGoga ransomware encrypts a wide range of file types and, depending on the command line argument, may target all files. Since the encryption process is slow, fast detection and remediation will limit the damage caused. Failure to detect the ransomware and take prompt action to mitigate the attack could prove costly. The ransomware can spread laterally through network connections and network shares, resulting in widespread file encryption.
The ransomware had a valid certificate that was issued to a UK firm by Comodo Certificate Authority. The certificate has since been revoked.
LockerGoga ransomware is currently being detected as malicious by 46/69 AV engines on VirusTotal, including Bitdefender, the primary AV engine used by SpamTitan.
A new Ursnif Trojan campaign has been detected that uses a new variant of the malware which uses fileless techniques to avoid detection. In addition to the banking Trojan, GandCrab ransomware is also downloaded.
Increase in Banking Trojan and Ransomware Combination Attacks
Ransomware attacks can cause considerable disruption to businesses, although a good backup strategy can allow businesses to recover quickly in the event of a successful attack without having to pay the ransom demand.
However, there has been a significant increase in phishing attacks that deliver not one but two malware variants – ransomware to extort money from companies but also an information stealer to obtain sensitive information such as login and banking credentials. Malware variants used in these attacks also have the capability to download other malware variants and gather system data and process information for use in further attacks.
These phishing campaigns allow hackers to maximize the profitability of attacks and make the attack profitable even if the business does not pay the ransom.
There have been several examples of these attacks in recent months. Earlier in January, warnings were issued about the combination of Ryuk ransomware with the Trickbot and Emotet Trojans – Two malware variants that are used in wire fraud attacks. Ryuk ransomware has been extensively used in attacks on U.S. healthcare providers. The combination with the banking Trojans makes the attacks far more damaging.
Now another campaign has been detected using different malware variants – The Ursnif Trojan and the latest version of GandCrab ransomware.
What Does the Ursnif Trojan Do?
The Ursnif Trojan is one of the most active banking Trojans currently in use. The main functions of the malware is to steal system information and bank account credentials from browsers. The latest variants of the Ursnif Trojan have also been used to deploy other malware variants such as GandCrab ransomware.
According to security researchers at Carbon Black, who identified the latest campaign, the Ursnif Trojan now uses fileless execution mechanisms to make detection more difficult. Instead of downloading and writing files to the hard drive – which can be detected – a PowerShell script downloads a payload and executes it in the memory. That payload then downloads a further file and injects it into the PowerShell process, ultimately resulting in the downloading of the ransomware.
When code is loaded in the memory, it often does not survive a reboot, although the latest variant of Ursnif has persistence. This is achieved by storing an encoded PowerShell command inside a registry key and subsequently launching the command via the Windows Management Instrumentation Command-line (WMIC).
Once information has been collected from an infected system, it is packaged inside a CAB file and sent back to the attackers C2 via encrypted HTTPS. This makes data exfiltration difficult to detect.
The Ursnif Trojan campaign uses email as the attack vector with infection occurring via a Word document attachment that contains a VBA macro. If the attachment is opened and macros are enabled (automatically or manually), the infection process will be triggered.
How Businesses can Protect Against Attacks
Due to the difficulty detecting the malware attack once it has started, the best way to protect against this attack is by improving anti-phishing defenses. It is important to prevent the malicious emails from being delivered to inboxes and to ensure that employees are trained how to identify the messages if they make it past email defenses. The former can be achieved with a powerful spam filtering solution such as SpamTitan.
Along with security awareness training for employees to condition them not to open emails from unknown senders or open attachments and enable macros, businesses can mount an effective defense against the attack.
SMB cybersecurity protections do not need to be advanced as those of large enterprises, but improvements need to be made to ensure smaller businesses are protected. The risk of a cyberattack is not theoretical. While large businesses are having their defenses regularly tested, small to medium sized businesses are also being attacked. And alarmingly often.
Large businesses may store much higher volumes of valuable data, but they also tend to invest heavily in the latest cybersecurity technologies and have dedicated teams to oversee security. Cyberattacks are therefore much harder to pull off. SMBs are much easier targets. Cyberattacks may be less profitable, but they are easier and require less effort.
SMB Cyberattacks are Increasing
A 2017 SCORE study confirmed the extent to which hackers are attacking SMBs. Its study of macro-based malware showed there had been at least 113,000 attacks on SMBs in 2017 and 43% of those attacks were on SMBs. SMBs suffered at least 54,000 ransomware attacks in 2017 and online banking attacks were highly prevalent in the SMB sector.
The 2018 State of Cybersecurity in Small and Medium Size Businesses study, conducted by the Ponemon Institute, painted an even bleaker picture for SMBs. The study suggests SMBs face the same cybersecurity risks as larger businesses and are being attacked almost as often. In its study, 67% of SMB respondents reported having experienced a cyberattack in the past 12 months and 58 had suffered a data breach. Alarmingly, almost half of respondents (47%) said they had little or no understanding about how SMB cyberattacks could be prevented.
The study revealed 60% of successful cyberattacks were the result of employee negligence, hackers were behind 37% of breaches, and for 32% of cyberattacks the cause could not be established.
The high number of successful cyberattacks makes it clear that SMB cybersecurity needs to be improved. Unfortunately, many SMBs simply don’t have the budget to pay for expensive cybersecurity solutions and a lack of skilled staff is also an issue. So, given these restraints, where should SMBs start?
Where to Start with SMB Cybersecurity
Improving SMB cybersecurity does not necessarily mean hiring skilled cybersecurity staff and spending heavily on state-of-the-art cybersecurity solutions. The best place to start is by ensuring basic cybersecurity best practices are adopted. Highly sophisticated cyberattacks are becoming more common, but many successful attacks are the result of basic cybersecurity failures.
These include the failure to implement password policies that enforce the use of strong passwords, not changing all default passwords, or not using a unique password for each account. Implementing 2-factor authentication is a quick way to improve security, as is the setting of rate limiting to lock accounts after a set number of failed login attempts.
Many successful cyberattacks start with a phishing email. An advanced spam filtering solution is therefore essential. This will ensure virtually all malicious messages are blocked and are not delivered to end users. A web filter also offers protection against phishing by preventing employees from visiting phishing websites. It will also block web-based attacks and malware downloads. Both of these SMB cybersecurity solutions can be implemented at a low cost. It costs just a few dollars per year, per employee, to implement SpamTitan and WebTitan.
A little training goes a long way. Employees should be provided with cybersecurity training and should be taught how to identify email and web-based threats. There are plenty of free and low-cost resources for SMBs to help them train their employees. US-CERT is a good place to start.
Good backup policies are an essential part of SMB cybersecurity. In the event of a cyberattack or ransomware attack, this will prevent catastrophic data loss. A good strategy to adopt is the 3-2-1 approach. Three copies of backups, on two different types of media, with one copy stored securely off-site. Also make sure backups are tested to ensure file recovery is possible.
Once the basics have been covered, it is important to conduct a security audit to discover just how secure your network and systems are. Many managed service providers can assist with security audits and assessments if you do not have sufficiently skilled staff to perform an audit inhouse.
Improvements to SMB cybersecurity will carry a cost but bear in mind that an ounce of security is worth a pound of protection and investment in cybersecurity will prove to be much less expensive than having to deal with a successful cyberattack.
Barely a day goes by without an announcement being made about an email account compromise, especially in the healthcare industry, but how does business email get hacked? What are the main ways that email account access is gained by unauthorized individuals?
Four Ways Business Email Gets Hacked
There four main ways that business email gets hacked, although fortunately there are simple steps that can be taken to improve email security and reduce the risk of an email account compromise at your business.
The easiest way for a hacker to gain access to a business email account is to ask the account holder for their password. This method is incredibly simple, costs next to nothing, and is very effective. Phishing, like fishing, uses a lure to achieve its aim. An attacker only needs to craft an email with a plausible reason for divulging a password.
The attack could be as simple as spoofing an email from the IT department that requests the user change his or her password for security reasons. A link is supplied in the email that directs the user to a site where they have to enter their password and a replacement. Office 365 phishing scams are now common. A user is directed to a spoofed website where they are presented with a standard Office 365 login box, which they need to enter to open a shared file for example.
The lures are diverse, although there is usually a valid reason for providing login credentials, urgency, and often a threat – The failure to take action will result in harm or loss.
Brute Force Attacks
An alternative method of hacking a business email account is for the attacker to attempt to guess a user’s password. This is a much more long-winded approach that can require thousands of attempts before the password is guessed. This technique is automated and made easier by poor password choices and the failure to change default passwords. Passwords obtained in previous breaches can be used, which will catch out people who use the same passwords for multiple platforms. Information about a person can also be found on social media – A partner’s name, child’s name, pet name, or dates of birth – Information that is commonly used to create passwords.
A man-in-the-middle attack involves an attacker intercepting information such as a password when it is sent between two parties. Information can be intercepted in unencrypted emails or when a user logs into a web-based platform via their browser. Man-in-the-middle attacks are common on unsecured public Wi-Fi networks and evil twin Wi-Fi hotspots – Hotspots that mimic a genuine hotspot provider, such as a coffee shop or hotel. Any information transmitted via that hotspot can be easily intercepted.
Writing Down Passwords
Many businesses have implemented password polices that require the use of strong and difficult to remember passwords. As a result, some employees write their passwords down on post-it notes, tape a password to their computer, or keep a note under their keyboard where any visitor to an office could discover it.
How to Stop Business Email Getting Hacked
These methods of gaining access to business email accounts are easy and inexpensive to block through low-cost cybersecurity solutions, policies and procedures, and staff training.
For businesses, the most important control to implement to protect against phishing is an advanced spam filter. A spam filter inspects all incoming emails for common spam signatures and malicious links and blocks messages before they are delivered to end users. Some spam filters also inspect outgoing email, which helps to prevent a breached email account from being used for further phishing attacks on contacts.
Even the best spam filters will not block every single phishing email so security awareness training for staff is essential. Regular training sessions should be provided – at least twice annually – and these should be augmented with more regular reminders about security and newsletters about the latest threats. Phishing simulations are useful for testing the effectiveness of training and to condition employees how to respond to email threats.
Brute force attacks are best prevented with good password policies that prevent weak passwords from being set. To prevent employees from writing passwords down, consider paying for a password manager or allowing the use of long passphrases, which are easy to remember but difficult to guess. Ensure two-factor authentication is enabled and rate limiting is applied to block login attempts after a set number of failed password guesses.
Man-in-the-middle attacks can be prevented in a number of ways. Remote workers should be provided with a VPN to access work networks and email. Some web filters, WebTitan for instance, can be used to protect remote workers online and prevent man-in-the-middle attacks and can also to prevent users from visiting malicious websites, such as those used for phishing.

To protect their clients from phishing attacks, Managed Service Providers (MSPs) need to provide a comprehensive range of cybersecurity solutions. This post explores the risks from phishing and suggests some easy to implement anti-phishing solutions for MSPs to add to their security offerings.
Phishing is the Number One Cyber Threat Faced by SMBs
Phishing is the number one cyber threat faced by businesses and one of the hardest to defend against. All it takes is for an employee to respond to a single phishing email for a costly data breach to occur. The consequences for the company can be severe.
Email accounts contain a wide range of sensitive information. A phishing attack on a UnityPoint Health hospital in Des Moines, IA, in 2018 saw the protected health information of 1.4 million patients compromised. Also in 2018, a phishing attack on the Boys Town National Research Hospital saw one account compromised that contained the information of more than 105,300 patients. Phishing emails are also used to introduce malware and ransomware. These attacks can be even more damaging and costly to mitigate.
The healthcare industry is extensively targeted by phishers due to the high value of healthcare data, although all industry sectors are at risk. In response to the high number of cyberattacks and the current threat levels, the Trump administration recently launched the “Know the Risk, Raise your Shield” campaign. The campaign aims to raise awareness of the threat from phishing and other attack methods and encourage private businesses to do more to improve their defenses.
Phishing will continue to be a major threat to businesses for the foreseeable future. Attacks will continue because they require relatively little skill to conduct, phishing is highly effective, and attacks can be extremely lucrative.
Easy to Implement Anti-Phishing Solutions for MSPs
There is no single solution that will provide total protection against phishing attacks. Businesses need layered defenses, which provides an opportunity for MSPs. SMBs can struggle to implement effective defenses against phishing on their own and look to MSPs for assistance.
MSPs that can provide a comprehensive anti-phishing package will be able to protect their clients, prevent costly phishing attacks, and generate more business. Effective anti-phishing controls are also an easy sell. Given the cost of mitigating attacks, the package is likely to pay for itself. But what solutions should be included in MSPs anti-phishing offerings?
Listed below are three easy-to-implement anti-phishing solutions for MSPs to offer to their clients, either individually or part of an anti-phishing security package.
Advanced Spam Filtering
Advanced spam filtering solutions are essential. They block phishing emails on the server before they can be delivered to inboxes or employees’ spam folders. An advanced spam filter will block in excess of 99.9% of spam and malicious emails and by itself, is the single most important solution to implement.
SpamTitan is an ideal anti-phishing solution for MSPs. This cloud-based solution supports an unlimited number of domains, all of which can be protected through an easy to use interface. The solution supports per domain administrators, with each able to implement elements of their own email such as searches and release of messages from quarantine. Reports can be generated per domain and those reports can be automatically sent to clients. The solution can be fully rebranded to take MSP logos and color schemes, and the solution can be hosted in a private cloud.
Security Awareness Training and Testing
While the majority of malicious emails will be blocked at source, a very small percentage may slip through the net. It is therefore essential for employees to be aware of the risks from phishing and to have the skills to identify potential phishing emails. MSPs can help their clients by providing a staff training program. Many security awareness training companies offer MSP programs to help manage training for clients and a platform to conduct phishing simulation exercises to test security awareness.
DNS-Based Web Filtering
Even with training, some employees may be fooled by phishing emails. This is to be expected, since many phishing campaigns use messages which are highly realistic and virtually indistinguishable from genuine emails. Spam filters will block malicious attachments, but a web filter offers protection from malicious hyperlinks that direct users to phishing websites.
A DNS-based web filter blocks attempts by employees to access phishing websites at the DNS-level, before any content is downloaded. When an employee clicks on a phishing email, they will be directed to a block screen rather than the phishing website. Being DNS-based, web filters are easy to implement and no appliances are required.
WebTitan is an ideal web filtering solution for MSPs. WebTitan can be configured in just a couple of minutes and can protect all clients from web-based phishing attacks, with the solution managed and controlled through a single easy-to-use interface. Reports can be automatically scheduled and sent to clients, and the solution is available in full white-label form ready for MSPs branding. A choice of hosting solutions is also offered, and the solution can connect with deployment, billing and management tools through APIs.

A new Netflix phishing scam has been detected that attempts to fool Netflix subscribers into disclosing their login credentials and other sensitive information such as Social Security numbers and bank account numbers.
This Netflix phishing scam is similar to others that have been intercepted over the past few months. A major campaign was detected in October and another in November. The latest Netflix phishing scam confirms that the threat actors are now launching large-scale phishing attacks on a monthly basis.
The number of recent Netflix scams and the scale of the campaigns has prompted the U.S. Federal Trade Commission (FTC) to issue a warning to raise awareness of the threat.
The latest campaign was detected by an officer in the Ohio Police Department. As with past campaigns, the attackers use a tried and tested method to get users to click on the link in the email – The threat of account closure due to issues with the user’s billing information.
In order to prevent closure of the user’s Netflix account a link in the email must be clicked. That will direct the user to the Netflix site where login credentials and banking information must be entered. While the web page looks genuine, it is hosted on a domain controlled by the attackers. Any information entered on that web page will be obtained by the threat actors behind the scam.
The emails appear genuine and contain the correct logos and color schemes and are almost identical to the official emails sent to users by Netflix. Netflix also includes links in its emails, so unwary users may click without first checking the authenticity of the email.
Image Source: FTC via Ohio Police Department
There are signs that the email is not what it seems. The email is incorrectly addressed “Hi Dear”; British English is used, even though the email is sent to U.S. citizens; the email is sent from a domain that is not used by Netflix; and the domain to which the email directs users is similarly suspect. However, the scam is sure to fool many users who fail to carefully check emails before taking any action.
Consumers need to exercise caution with email and should carefully check messages before responding, no matter how urgent the call for action is. It is a good best practice to always visit a website directly by entering in the domain into the address bar of a web browser, rather than clicking a link in an email.
If the email is determined to be a scam, it should be reported to the appropriate authorities in the country in which you reside and also to the company the scammers are impersonating. In the case of Netflix phishing scams, emails should be sent to email@example.com.
While this Netflix phishing scam targets consumers, businesses are also at risk. Many similar scams attempt to get users to part with business login credentials and bank account information. Businesses can reduce the risk of data and financial losses to phishing scams by ensuring all members of the company, from the CEO down, are given regular security awareness training and are taught cybersecurity best practices and are made aware of the latest threats.
An advanced spam filtering solution is also strongly recommended to ensure the vast majority of these scam emails are blocked and do not reach inboxes. SpamTitan for instance, blocks more than 99.9% of spam and phishing emails and 100% of known malware.
For further information on anti-phishing solutions for businesses, contact the TitanHQ team today.

According to a recent Irish phishing study, as many as 185,000 office workers in the country have fallen victim to phishing scams.
Phishing is a method used by cybercriminals to obtain sensitive information such as login credentials, financial information, and other sensitive data. While phishing can take place over the phone, via messaging platforms or by text message, email is most commonly used.
Messages are sent in bulk in the hope that some individuals will respond, or campaigns can be much more targeted. The latter is referred to as spear phishing. With spear phishing attacks, cybercriminals often research their victims and tailor messages to maximize the probability of them eliciting a response.
A successful phishing attack on employees can see them disclose their email credentials which allows their accounts to be accessed. Then the attackers can search emails accounts for sensitive information or use the accounts to conduct further phishing attacks on other employees. When financial information is disclosed, business bank accounts can be emptied.
Businesses can suffer major financial losses as a result of employees responding to phishing emails, the reputation of the business can be damaged, customers can be lost, and there is also a risk of major regulatory fines.
Irish Phishing Study Findings
The Irish phishing study was conducted on 500 Irish office workers by the survey consultancy firm Censuswide. Respondents to the Irish phishing study were asked questions about phishing, whether they had fallen for a phishing scam in the past, and how they rated their ability to identify phishing attacks.
In line with findings from surveys conducted in other countries, 14% of respondents said they had been a victim of a phishing attack. There were also marked differences between different age groups. Censuswide analyzed three age groups: Millennials, Gen X, and baby boomers. The latter two age groups were fairly resistant to phishing attempts. Gen X were the most phishing-savvy, with just 6% of respondents in the age group admitting to having been fooled by phishing emails in the past, closely followed by the baby boomer generation on 7%. However, 17% of millennials admitted having fallen for a phishing scam – The generation that should, in theory, be the most tech-savvy.
Interestingly, millennials were also the most confident in their ability to recognize phishing attempts. 14% of millennials said they would not be certain that they could detect fraud, compared to 17% of Gen X, and 26% of baby boomers.
It is easy to be confident about one’s ability to spot standard phishing attempts, but phishing attacks are becoming much more sophisticated and very realistic. Complacency can be very dangerous.
Phishing Protection for Businesses
The results of the Irish phishing study make it clear that businesses need to do more to protect themselves from phishing attacks. Naturally, an advanced spam filtering solution is required to ensure that employees do not have their phishing email identification skills put to the test constantly. SpamTitan, for instance, blocks more than 99.9% of spam and phishing emails, thus reducing reliance on employees’ ability to identify scam emails.
The Irish phishing study also highlights the importance of providing security awareness training to employees. The study revealed 44% of the over 54 age group had opened an attachment or clicked on a link in an email from an unknown sender, as had 34% of millennials and 26% of the Gen X age group. Alarmingly, one in five respondents said that their employer had not provided any security awareness training whatsoever.
Employees need to learn how to identify scams, so security awareness training must be provided. Since cybercriminals’ tactics are constantly evolving, training needs to be continuous. Annual or biannual training sessions should be provided, along with shorter refresher training sessions. Businesses should also consider conducting phishing email simulations to test resilience to phishing attacks and highlight weak links.
To be effective, anti-phishing training needs to be provided to all employees and requires buy-in from all departments. Unless that happens, it will be difficult to develop a culture of security awareness.
In this post we offer four simple steps to take to improve Office 365 security and make it harder for hackers and phishers to gain access to users’ accounts.
Hackers are Targeting Office 365 Accounts
It should come as no surprise to hear that hackers are targeting Office 365 accounts. Any software package that has 155 million global users is going to be a target for hackers, and with the number of users growing by an astonishing 3 million a month, Office 365 accounts are likely to be attacked even more frequently.
One study this year has confirmed that to be the case. There has been a 13% increase in attempts to hack into Office 365 email accounts this year, and many of those attacks succeed. You should therefore take steps to improve Office 365 security.
Hackers themselves are paying for Office 365 and are probing its security protections to find vulnerabilities that can be exploited. They also test their phishing emails on real office 365 accounts to find out which ones bypass Microsoft’s anti-phishing protections.
When emails have been developed that bypass Microsoft’s anti-phishing protections, mass email campaigns are launched on Office 365 users. Businesses using Office 365 can easily be found and targeted because it is made clear that they use Office 365 through public DNS MX records.
So how can you improve office 365 security and make it harder for hackers? If you take the four steps below, you will be able to greatly improve Office 365 security and thwart more attacks.
Enforce the Use of Strong Passwords
Hackers often conduct brute force attacks on Office 365 email accounts so you need to develop a strong password policy and prevent users from setting passwords that are easy to brute force. You should not allow dictionary words or any commonly used weak passwords, that otherwise meet your password policy requirements – Password1! for instance.
The minimum length for a password should be 8 characters but consider increasing that minimum. A password of between 12 and 15 characters is recommended. Make sure you do not set a too restrictive maximum number of characters to encourage the use of longer passphrases. Passphrases are harder to crack than 8-digit passwords and easier for users to remember. To make it even easier for your users, consider using a password manager.
Implement Multi-Factor Authentication
Even with strong passwords, some users’ passwords may be guessed, or users may respond to phishing emails and disclose their password to a scammer. An additional login control is therefore required to prevent compromised passwords from being used to access Office 365 accounts.
Multi-factor authentication is not infallible, but it will help you improve Office 365 security. With MFA, in addition to a password, another method of authentication is required such as a token or a code sent to a mobile phone. If a password is obtained by a hacker, and an attempt is made to login from a new location or device, further authentication will be required to access the account.
Enable Mailbox Auditing in Office 365
Mailbox auditing in Office 365 is not turned on by default so it needs to be enabled. You can set various parameters for logging activity including successful login attempts and various mailbox activities. This can help you identify whether a mailbox has been compromised. You can also logs failed login attempts to help you identify when you are being attacked.
Improve Office 365 Security with a Third-Party Spam Filter
As previously mentioned, hackers can test their phishing emails to find out if they bypass Office 365 anti-phishing controls and your organization can be identified as using Office 365. To improve Office 365 security and reduce the number of phishing emails that are delivered to end users’ inboxes, consider implementing a third-party spam filter rather than relying on Microsoft’s anti-phishing controls. Dedicated email security vendors, such as TitanHQ, offer more effective and more flexible anti-spam and anti-phishing solutions than Microsoft Advanced Threat Protection at a lower cost.
A U.S. school system had Office 365 spam filtering controls in place and other cybersecurity solutions installed, but still experienced a costly 6-week malware infection. In this post we explore what went wrong and how you can improve security in your organization.
Multi-Layered Defenses Breached
If you want to mount a solid defense and prevent hackers from gaining access to your networks and data, multi-layered cybersecurity defenses are required, but for one Georgia school district that was not enough. On paper, their defenses looked sound. Office 365 spam filtering controls had been applied to protect the email system, the school district had a firewall appliance protecting the network, and a web filter had been installed to control what users could do online. Endpoint security had also been installed.
The school district was also updating its desktops to Windows 10 and its servers to Windows Server 2012 or later. Everything looked nice and secure.
However, the transportation department delayed the upgrades. The department was still sharing files on a local Windows 2003 server and some of the desktops were still running Windows XP, even though support for the OS had long since ended. The outdated software and lack of patching was exploited by the attackers.
How Was the Malware Installed?
The investigation has not yet determined exactly how the attack was initiated, but it is believed that it all started with an email. As a result of the actions of an end user, a chain of events was triggered that resulted in a 6-week struggle to mitigate the attack, the cost of which – in terms of time and resources – was considerable.
The attack is believed to have started on a Windows XP machine with SMBv1 enabled. That device had drives mapped to the Windows 2003 server. The malware that was installed was the Emotet Trojan, which used the EternalBlue exploit to spread across the network to other vulnerable devices. The attackers were able to gain control of those devices and installed cryptocurrency mining malware.
The cryptocurrency mining slowed the devices to such an extent that they were virtually unusable, causing many to continually crash and reboot. The network also slowed to a snail’s pace due to the streams of malicious traffic. While the upgraded Windows 10 machines were not affected initially, the attackers subsequently downloaded keyloggers onto the compromised devices and obtained the credentials of an IT support technician who had domain administration rights. The attackers then used those privileges to disable Windows Defender updates on desktops, servers, and domain controllers.
Over the course of a week, further Trojan modules were downloaded by creating scheduled tasks using the credentials of the IT support worker. A spam module was used to send malicious messages throughout the school district and several email accounts were compromised as a result and had malware downloaded. Other devices were infected through network shares. The TrickBot banking Trojan was downloaded and was used to attack the systems used by the finance department, although that Trojan was detected and blocked.
Remediation Took 6 Weeks
Remediating the attack was complicated. First the IT department disabled SMBv1 on all devices as it was not known what devices were vulnerable. Via a Windows Group Policy, the IT team then blocked the creation of scheduled tasks. Every device on the network had Windows Defender updates downloaded manually, and via autoruns for Windows, all processes and files run by the Trojan were deleted. The whole process of identifying, containing, and disabling the malware took 6 weeks.
The attack was made possible through an attack on a single user, although it was the continued use of unsupported operating systems and software that made the malware attack so severe.
The attack shows why it is crucial to ensure that IT best practices are followed and why patching is so important. For that to happen, the IT department needs to have a complete inventory of all devices and needs to make sure that each one is updated.
While Microsoft released a patch to correct the flaw in SMBv1 that was exploited through EternalBlue, the vulnerable Windows XP devices were not updated, even though Microsoft had released an update for the unsupported operating system in the spring of 2017.
Additional Protection is Required for Office 365 Inboxes
The attack also shows how the actions of a single user can have grave repercussions. By blocking malicious emails at source, attacks such as this will be much harder to pull off. While Office 365 spam filtering controls block many email-based threats, even with Microsoft’s Advanced Threat Protection many emails slip through and are delivered to inboxes.
Hackers can also see whether Office 365 is being used as it is broadcast through DNS MX records, which allows them to target Office 365 users and launch attacks.
Due to the additional cost of APT, the lack of flexibility, and the volume of malicious emails that are still delivered to inboxes, many businesses have chosen to implement a more powerful spam filtering solution on top of Office 365.
One such solution that has been developed to work seamlessly with Office 365 to improve protection against email threats is SpamTitan.
Sextortion scams have proven popular with cybercriminals this year. A well written email and an email list are all that is required. The latter can easily be purchased for next to nothing via darknet marketplaces and hacking forums. Next to no technical skill is required to run sextortion scams and as scammers’ Bitcoin wallets show, they are effective.
Many sextortion scams use the tried and tested technique of threatening to expose a user’s online activities (pornography habits, dating/adultery site usage) to all their contacts and friends/family unless a payment is made. Some of the recent sextortion scams have added credibility by claiming to have users’ passwords. However, new sextortion scams have been detected in the past few days that are using a different tactic to get users to pay up.
The email template used in this scam is similar to other recent sextortion scams. The scammers claim to have a video of the victim viewing adult content. The footage was recorded through the victim’s webcam and has been spliced with screenshots of the content that was being viewed at the time.
In the new campaign the email contains the user’s email account in the body of the email, a password (Most likely an old password compromised in a previous breach), and a hyperlink that the victim is encouraged to click to download the video that has been created and see exactly what will soon be distributed via email and social media networks.
Clicking the link in the video will trigger the downloading of a zip file. The compressed file contains a document including the text of the email along with the supposed video file. That video file is actually an information stealer – The Azorult Trojan.
This form of the scam is even more likely to work than past campaigns. Many individuals who receive a sextortion scam email will see it for what it really is: A mass email containing an empty threat. However, the inclusion of a link to download a video is likely to see many individuals download the file to find out if the threat is real.
If the zip file is opened and the Azorult Trojan executed, it will silently collect information from the user’s computer – Similar information to what the attacker claims to have already obtained: Cookies from websites the user has visited, chat histories, files stored on the computer, and login information entered through browsers such as email account and bank credentials.
However, it doesn’t end there. The Azorult Trojan will also download a secondary payload: GandCrab ransomware. Once information has been collected, the user will have their personal files encrypted: Documents, spreadsheets, digital photos, databases, music, videos, and more. Recovery will depend on those files having been backed up and not also encrypted by the ransomware. Aside from permanent file loss, the only other alternative will be to pay a sizeable ransom for the key to decrypt the files.
If the email was sent to a business email account, or a personal email account that was accessed at work, files on the victim’s work computer will be encrypted. Since a record of the original email will have been extracted on the device, the reason why the malware was installed will be made clear to the IT department.
The key to not being scammed is to ignore any threats sent via email and never click links in the emails nor open email attachments.
Businesses can counter the threat by using cybersecurity solutions such as spam filters and web filters. The former prevents the emails from being delivered while the latter blocks access to sites that host malware.
The search for Christmas gifts can be a difficult process. All too often that search proves to be unfruitful and consumers opt to buy gift cards instead. At least with a gift card you can be sure that your friends and family members will be able to buy a gift that they want; however, beware of holiday season gift card scams. Many threat actors are using gift cards as the lure to fool end users into installing malware or parting with sensitive information.
Holiday Season Sees Marked Increase Gift Card Phishing Scams
Holiday season gift card scams are commonplace, and this year is no exception. Many gift card-themed scams were detected over Thanksgiving weekend that offered free or cheap gift cards to lure online shoppers into parting with their credit card details.
Everyone loves a bargain and the offer of something for nothing may be too hard to resist. Many people fall for these scams which is why threat actors switch to gift card scams around this time of year.
Consumers can be convinced to part with credit card details, but businesses too are at risk. Many of these campaigns are conducted to gain access to login credentials or are used to install malware. If an end user responds to such a scam while at work, it is their employer that will likely pay the price.
This year has seen many businesses targeted with gift card scams. Figures from Proofpoint suggest that out of the organizations that have been targeted with email fraud attacks, almost 16% had experienced a gif card-themed attack: Up from 11% in Q2, 2018.
This year has also seen an increase in business email compromise (BEC) style tactics, with emails appearing to have been sent from within a company. The emails claim to have been sent from the CEO (or another executive) requesting accounts and administration staff purchase gift cards for clients or ask for gift cards be purchased to be used for charitable donations.
To reduce the risk from gift card scams and other holiday-themed phishing emails, businesses need to ensure they have powerful spam filtering technology in place to block the emails at source and prevent them from being delivered to inboxes.
Advanced Anti-Phishing protection for Office 365
Many businesses use Office 365, but even Microsoft’s anti-phishing protections see many phishing emails slip through the net, especially at businesses that have not paid extra for advanced phishing protection. Even with the advanced anti-phishing controls, emails still make it past Microsoft’s filters.
To block these malicious messages, an advanced third-party spam filter is required. SpamTitan has been developed to work seamlessly with Office 365 to improved protection against malware, phishing emails, and more sophisticated phishing attacks.
SpamTitan blocks more than 99.9% of spam email, while dual anti-virus engines block 100% of known malware. What really sets SpamTitan in a different class is the level of protection it offers against new threats. A combination of Bayesian analysis, greylisting, machine learning, and heuristics help to identify zero-day attacks, which often slip past Office 365 defenses.
If you want to improve protection from email-based attacks and reduce the volume of spam and malicious messages that are being delivered to Office 365 inboxes, give TitanHQ a call today and book a product demonstration to see SpamTitan in action. You can sign up for a free trial of SpamTitan to test the solution in your own environment and see for yourself the difference it makes.
There has been an increase in phishing attacks on retailers, supermarket chains, and restaurants in recent weeks. The aim of the phishing attacks is to deliver remote access Trojans and remote manipulator software to gain persistent access to computers and, ultimately, obtain banking credentials and sensitive customer data on POS systems.
Several new campaigns have been detected in recent weeks targeting retail and food sector companies, both of which are well into the busiest time of the year. With employees working hard, it is likely that less care will be taken opening emails which gives cybercriminals an opportunity.
PUB Files Used in Phishing Attacks on Retailers
Over the past few weeks, security researchers have noted an uptick in phishing attacks on retailers, with one threat group switching to using.pub files to install malware. Many phishing attacks use Word documents containing malicious macros. The use of macros with .pub files is relatively uncommon. The change to this new attachment type may fool employees, as they will be less likely to associate these files with cyberattacks.
Social engineering techniques are used to fool end users into opening the files, with the .pub files masquerading as invoices. Many emails have been intercepted that appear to have been sent from within a company, which helps to make the files appear genuine.
If opened, the .pub files, via malicious macros, run Microsoft Installer (MSI) files that deliver a remote access Trojan. Since these installers will most likely be familiar to end users, they may not realize the installers are malicious. Further, the MSI files are time delayed so they do not run immediately when the .pub files are opened, increasing the probability that the RAT downloads will go unnoticed.
The TA505 threat group is using this tactic to install the FlawedAmmy remote access Trojan and other malicious payloads such as Remote Manipulator System (RMS) clients.
The phishing emails used to deliver these malicious files are targeted and tailored to a specific business to increase the likelihood of success. These targeted spear phishing attacks are now becoming the norm, as threat actors move away from the spray and pray tactics of old.
Cape Cod Community College Phishing Attack Results in Theft of More Than $800,000
Phishing attacks on retailers have increased, but other industries are also at risk. Educational institutions are also prime targets, as has been highlighted by a recent phishing attack on Cape Cod Community College.
The Cape Cod Community College phishing attack involved sophisticated messages that delivered malware capable of evading the college’s anti-virus software. The malware was used to obtain the banking credentials of the college, and once those credentials had been obtained, the hackers proceeded to make fraudulent transfers and empty bank accounts. Transfers totaling $807,130 were made, and so far, the college and its bank have only been able to recover $278,887.
All too often, fraudulent transfers are not detected quickly enough to recover any funds. Once the transfers have cleared the attacker-controlled bank accounts are emptied, after which the probability of recovering funds falls to near zero.
Defense in Depth the Key to Phishing Protection
Email is the primary vector used to phish for sensitive information and deliver malware to businesses. Regardless of whether businesses use local email systems or cloud-based email services such as Office 365, advanced spam filtering controls are required to block threats. For instance, SpamTitan blocks more than 99.9% of spam email and 100% of known malware. SpamTitan also uses heuristics, machine learning, and Bayesian analysis to identify previously unseen threats – One of the areas of weakness of Office 365’s anti-phishing defenses.
Network segmentation is also essential. Critical services must be separated to ensure that the installation of malware or ransomware on one device will not allow the attackers to gain access to the entire network. This is especially important for retailers and other businesses with POS systems. Network segmentation will help to keep POS systems and the financial data of customers secure.
Advanced endpoint protection solutions offer far greater protection than standard antivirus solutions and are less reliant on malware signatures. Standard AV solutions will only block known malware. With standard AV solutions, new malware variants can easily slip through the net.
End user security awareness training should be mandatory for all employees and training needs to be a continuous process. A once a year training session is no longer sufficient. Regular training throughout the year is required to ensure employees are made aware of the latest threats and tactics being used to gain access to login credentials and install malware.

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

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

Phishing is the number one security threat faced by businesses. In this post we explore why phishing is such as serious threat and the top phishing lures that are proving to be the most effective at getting employees to open malicious attachments and click on hyperlinks and visit phishing websites.
Phishing is the Biggest Security Threat Faced by Businesses
Phishing is a tried and tested social engineering technique that is favored by cybercriminals for one very simple reason. It is very effective. Phishing emails can be used to fool end users into installing malware or disclosing their login credentials. It is an easy way for hackers to gain a foothold in a network to conduct further cyberattacks on a business.
Phishing works because it targets the weakest link in security defenses: End users. If an email is delivered to an inbox, there is a relatively high probability that the email will be opened. Messages include a variety of cunning ploys to fool end users into taking a specific action such as opening a malicious email attachment or clicking on an embedded hyperlink.
Listed below are the top phishing lures of 2018 – The messages that have proven to be the most effective at getting end users to divulge sensitive information or install malware.
Top Phishing Lures of 2018
Determining the top phishing lures is not straightforward. Many organizations are required to publicly disclose data breaches to comply with industry regulations, but details of the phishing lures that have fooled employees are not usually made public.
Instead, the best way to determine the top phishing lures is to use data from security awareness training companies. These companies have developed platforms that businesses can use to run phishing simulation exercises. To obtain reliable data on the most effective phishing lures it is necessary to analyze huge volumes of data. Since these phishing simulation platforms are used to send millions of dummy phishing emails to employees and track responses, they are useful for determining the most effective phishing lures.
In the past few weeks, two security awareness training companies have published reports detailing the top phishing lures of 2018: Cofense and KnowBe4.
Top Phishing Lures on the Cofense Platform
Cofense has created two lists of the top phishing lures of 2018. One is based on the Cofense Intelligence platform which collects data on real phishing attacks and the second list is compiled from responses to phishing simulations.
Both lists are dominated by phishing attacks involving fake invoices. Seven out of the ten most effective phishing campaigns of 2018 mentioned invoice in the subject line. The other three were also finance related: Payment remittance, statement and payment. This stands to reason. The finance department is the primary target in phishing attacks on businesses.
The list of the top phishing lures from phishing simulations were also dominated by fake invoices, which outnumbered the second most clicked phishing lure by 2 to 1.
Number of Reported Emails
New Message in Mailbox
Online Order (Attachment)
Secure Message (MS Office Macro)
Online Order (Hyperlink)
Confidential Scanned document (Attachment)
Conversational Wire transfer (BEC Scam)
Top Phishing Lures on the KnowBe4 Platform
KnowBe4 has released two lists of the top phishing lures of Q3, 2018, which were compiled from responses to simulated phishing emails and real-world phishing attempted on businesses that were reported to IT security departments.
The most common real-world phishing attacks in Q3 were:
You have a new encrypted message
IT: Syncing Error – Returned incoming messages
HR: Contact information
FedEx: Sorry we missed you.
Microsoft: Multiple log in attempts
IT: IMPORTANT – NEW SERVER BACKUP
Wells Fargo: Irregular Activities Detected on Your Credit Card
LinkedIn: Your account is at risk!
Microsoft/Office 365: [Reminder]: your secured message
Coinbase: Your cryptocurrency wallet: Two-factor settings changed
The most commonly clicked phishing lures in Q3 were:
% of Emails Clicked
Password Check Required Immediately
You Have a New Voicemail
Your order is on the way
Change of Password Required Immediately
De-activation of [[email]] in Process
UPS Label Delivery 1ZBE312TNY00015011
Revised Vacation & Sick Time Policy
You’ve received a Document for Signature
Spam Notification: 1 New Messages
[ACTION REQUIRED] – Potential Acceptable Use Violation
The Importance of Blocking Phishing Attacks at their Source
If login credentials to email accounts, Office 365, Dropbox, and other cloud services are obtained by cybercriminals, the accounts can be plundered. Sensitive information can be stolen and Office 365/email accounts can be used for further phishing attacks on other employees. If malware is installed, cybercriminals can gain full control of infected devices. The cost of mitigating these attacks is considerable and a successful phishing attack can seriously damage a company’s reputation.
Due to the harm that can be caused by phishing, it is essential for businesses of all sizes to train staff how to identify phishing threats and implement a system that allows suspicious emails to be reported to security teams quickly. Resilience to phishing attacks can be greatly improved with an effective training program and phishing email simulations. It is also essential to deploy an effective email security solution that blocks threats and ensures they are not delivered to inboxes.
SpamTitan is a highly effective, easy to implement email filtering solution that blocks more than 99.9% of spam and phishing emails and 100% of known malware through dual anti-virus engines (Bitdefender and ClamAV). With SpamTitan protecting inboxes, businesses are less reliant on their employees’ ability to identify phishing threats.
SpamTitan subjects each incoming email to a barrage of checks to determine if a message is genuine and should be delivered or is potentially malicious and should be blocked. SpamTitan also performs checks on outbound emails to ensure that in the event that an email account is compromised, it cannot be used to end spam and phishing emails internally and to clients and contacts, thus helping to protect the reputation of the business.
Improve Office 365 Email Security with SpamTitan
There are more than 135 million subscribers to Office 365, and such high numbers make Office 365 a big target for cybercriminals. One of the main ways that Office 365 credentials are obtained is through phishing. Emails are crafted to bypass Office 365 defenses and hyperlinks are used to direct end users to fake Office 365 login pages where credentials are harvested.
Businesses that have adopted Office 365 are likely to still see a significant number of malicious emails delivered to inboxes. To enhance Office 365 security, a third-party email filtering control is required. If SpamTitan is installed on top of Office 365, a higher percentage of phishing emails and other email threats can be blocked at source.
To find out more about SpamTitan, including details of pricing and to register for a free trial, contact the TitanHQ team today. During the free trial you will discover just how much better SpamTitan is at blocking phishing attacks than standard Office 365 anti-spam controls.
A new Office 365 threat has been detected that stealthily installs malware by hiding communications and downloads by abusing legitimate Windows components.
New Office 365 Threat Uses Legitimate Windows Files to Hide Malicious Activity
The attack starts with malspam containing a malicious link embedded in an email. Various themes could be used to entice users into clicking the link, although one recent campaign masquerades as emails from the national postal service in Brazil.
The emails claim the postal service attempted to deliver a package, but the delivery failed as there was no one in. The tracking code for the package is included in the email and the user is requested to click the link in the email to receive the tracking information.
In this case, clicking the link will trigger a popup asking the user to confirm the download of a zip file, which it is alleged contains the tracking information. If the zip file is extracted, the user is required to click on a LNK file to receive the information. The LNK file runs cmd.exe, which executes a Windows Management Instrumentation (WMI) file: wmic.exe. This legitimate Windows file will be used to communicate with the attacker’s C2 server and will create a copy of another Windows file – certutil.exe in the %temp% folder with the name certis.exe. A script then runs which instructs the certis.exe file to connect to a different C2 server to download malicious files.
The aim of this attack is to use legitimate Windows files to download the malicious payload: A banking Trojan. The use of legitimate Windows files for communication and downloading files helps the attackers bypass security controls and install the malicious payload undetected.
These Windows files have the capability to download other files for legitimate purposes, so it is hard for security teams to identify malicious activity. This campaign targets users in Brazil, but this Office 365 threat should be a concern for all users as other threat actors have also adopted this tactic to install malware.
Due to the difficultly distinguishing between legitimate and malicious wmic.exe and certutil.exe activity, blocking an office 365 threat such as this is easiest at the initial point of attack: Preventing the malicious email from being delivered to an inbox and providing security awareness training to employees to help them identify this Office 365 threat. The latter is essential for all businesses. Employees can be turned into a strong last line of defense through security awareness training. The former can be achieved with a spam filtering solution such as SpamTitan. SpamTitan will prevent the last line of defense from being tested.
How to Block this Office 365 Threat with SpamTitan and Improve Email Security
Microsoft uses several techniques to identify malspam and prevent malicious messages from reaching users’ inboxes; however, while efforts have been made to improve the effectiveness of the spam filtering controls of Office 365, many malicious messages are still delivered.
To improve Office 365 security, a third-party spam filtering solution should be used. SpamTitan has been developed to allow easy integration into Office 365 and provides superior protection against a wide range of email threats.
SpamTitan uses a variety of methods to prevent malspam from being delivered to end users’ inboxes, including predictive techniques to identify threats that are misidentified by Office 365 security controls. These techniques ensure industry-leading catch rates in excess of 99.9% and prevent malicious emails from reaching inboxes.
How SpamTitan Protects Businesses from Email Threats
Security Solutions for MSPs to Block Office 365 Threats
Many MSPs resell Office 365 licenses to their customers. Office 365 allows MSPs to capture new business, but the margins are small. By offering additional services to enhance Office 365 security, MSPs can make their Office 365 offering more desirable to businesses while improving the profitability of Office 365.
TitanHQ has been developing innovative email and web security solutions for more than 25 years. Those solutions have been developed from the ground up with MSPs for MSPs. Three solutions are ideal for use with Office 365 for compliance ad to improve security – SpamTitan email filtering, WebTitan web filtering, and ArcTitan email archiving.
By incorporating these solutions into Office 365 packages, MSPs can provide clients with much greater value as well as significantly boosting the profitability of offering Office 365.
To find out more about each of these solutions, speak to TitanHQ. The MSP team will be happy to explain how the products work, how they can be implemented, and how they can boost margins on Office 365.
Financial institutions, healthcare organizations and universities have seen an increase in cyberattack in recent months, but there has also been an increase in phishing attacks on publishers and literary scouting agencies.
Any business that stores sensitive information that can be monetized is at risk of cyberattacks, and publishers and literary scouting agencies are no exception. Like any employer, scouting agencies and publishers store sensitive information such as bank account numbers, credit card details, Social Security numbers, contract information, and W-2 Tax forms, all of which carry a high value on the black market. The companies also regularly make wire transfers and are therefore targets for BEC scammers.
However, in a somewhat new development, there have been several reports of phishing attacks on publishers and literary scouting agencies that attempt to gain access to unpublished manuscripts and typescripts. These are naturally extremely valuable. If an advance copy of an eagerly awaited book can be obtained before it is published, there will be no shortage of fans willing to pay top dollar for a copy. Theft of manuscripts can result in extortion attempts with ransoms demanded to prevent their publication online.
2018 has seen a significant increase in phishing attacks on publishers and literary scouting agencies. Currently, campaigns are being conducted by scammers that appear to have a good understanding of the industry. Highly realistic and plausible emails are being to publishing houses and agencies which use the correct industry terminology, which suggests they are the work of an industry insider.
One current campaign is spoofing the email account of Catherine Eccles, owner of the international literary scouting agency Eccles Fisher. Emails are being sent using Catherine Eccles’ name, and include her signature and contact information. The messages come from what appears to be her genuine email account, although the email address has been spoofed and replies are directed to an alternative account controlled by the scammer. The messages attempt to get other literary agencies to send manuscripts via email or disclose their website passwords.
An increase in phishing attacks on publishers on both sides of the Atlantic have been reported, with the threat already having prompted Penguin Random House North America to send out warnings to employees to alert them to the threat. According to a recent report in The Bookseller, several publishers have been targeted with similar phishing schemes, including Penguin Random House UK and Pan Macmillan.
Protecting against phishing attacks requires a combination of technical solutions, policies and procedures, and employee training.
Publishers and scouting agencies should deploy software solutions that can block phishing attacks and prevent malicious emails from being delivered to their employees’ inboxes.
SpamTitan is a powerful anti-phishing tool that blocks 99.97% of spam emails and 100% of known malware. DMARC email-validation is incorporated to detect email spoofing and prevent malicious emails from reaching employees’ inboxes.
End user training is also essential to raise awareness of the risks of phishing. All staff should be trained how to recognize phishing emails and other email threats to ensure they do not fall for these email scams.
If you run a publishing house or literary scouting agency and are interested in improving your cyber defenses, contact the TitanHQ team today for further information on cybersecurity solutions that can improve your security posture against phishing and other email and web-based threats.
Hackers have been going back to school and entering higher education. Quite literally in fact, although not through conventional channels. Entry is gained through cyberattacks on universities, which have increased over the course of the past 12 months, according to figures recently released by Kaspersky Lab.
Cyberattacks on Universities on the Rise
Credit cards information can be sold for a few bucks, but universities have much more valuable information. As research organizations they have valuable proprietary data. The results of research studies are particularly valuable. It may not be possible to sell data as quickly as credit cards and Social Security numbers, but there are certainly buyers willing to pay top dollar for valuable research. Nation state sponsored hacking groups are targeting universities and independent hacking groups are getting in on the act and conducting cyberattacks on universities.
There are many potential attack vectors that can be used to gain access to university systems. Software vulnerabilities that have yet to be patched can be exploited, misconfigured cloud services such as unsecured S3 buckets can be accessed, and brute force attempts can be conducted to guess passwords. However, phishing attacks on universities are commonplace.
Phishing is often associated with scams to obtain credit card information or login credentials to Office 365 accounts, with businesses and healthcare organizations often targeted. Universities are also in the firing line and are being attacked.
The reason phishing is so popular is because it is often the easiest way to gain access to networks, or at least gain a foothold for further attacks. Universities are naturally careful about guarding their research and security controls are usually deployed accordingly. Phishing allows those controls to be bypassed relatively easily.
A successful phishing attack on a student may not prove to be particularly profitable, at least initially. However, once access to their email account is gained, it can be used for further phishing attacks on lecturers for example.
Spear phishing attacks on lecturers and research associates offer a more direct route. They are likely to have higher privileges and access to valuable research data. Their accounts are also likely to contain other interesting and useful information that can be used in a wide range of secondary attacks.
Email-based attacks can involve malicious attachments that deliver information stealing malware such as keyloggers, although many of the recent attacks have used links to fake university login pages. The login pages are exact copies of the genuine login pages used by universities, the only difference being the URL on which the page is located.
More than 1,000 Phishing Attacks on Universities Detected in a Year
According to Kaspersky Lab, more than 1,000 phishing attacks on universities have been detected in the past 12 months and 131 universities have been targeted. Those universities are spread across 16 countries, although 83/131 universities were in the United States.
Preventing phishing attacks on universities, staff, and students requires a multi layered approach. Technical controls must be implemented to reduce risk, such as an advanced spam filter to block the vast majority of phishing emails and stop them being delivered to end users. A web filtering solution is important for blocking access to phishing websites and web pages hosting malware. Multi-factor authentication is also essential to ensure that if account information is compromised or passwords are guessed, an additional form of authentication is required to access accounts.
As a last line of defense, staff and students should be made aware of the risk from phishing. Training should be made available to all students and cybersecurity awareness training for researchers, lecturers, and other staff should be mandatory.
Office 365 phishing attacks are commonplace, highly convincing, and Office 365 spam filtering controls are easily being bypassed by cybercriminals to ensure messages reach inboxes. Further, phishing forms are being hosted on webpages that are secured with valid Microsoft SLL certificates to convince users the websites are genuine.
Office 365 Phishing Attacks Can Be Difficult to Identify
In the event of a phishing email making it past perimeter defenses and arriving in an inbox, there are several tell-tale signs that the email is not genuine.
There are often spelling mistakes, incorrect grammar, and the messages are sent from questionable senders or domains. To improve the response rate, cybercriminals are now spending much more time carefully crafting their phishing emails and they are often virtually indistinguishable from genuine communications from the brand they are spoofing. In terms of formatting, they are carbon copies of genuine emails complete with the branding, contact information, sender details, and logos of the company being spoofed. The subject is perfectly believable and the content well written. The actions the user is requested to take are perfectly plausible.
Hyperlinks are contained in emails that direct users to a website where they are required to enter their login credentials. At this stage of the phishing attack there are usually further signs that all is not as it seems. A warning may flash up that the website may not be genuine, the website may start with HTTP rather than the secure HTTPS, or the SSL certificate may not be owned by the company that the website is spoofing.
Even these tell-tale signs are not always there, as has been shown is several recent Office 365 phishing attacks, which have the phishing forms hosted on webpages that have valid Microsoft SSL certificates or SSL certificates that have been issued to other cloud service providers such as CloudFlare, DocuSign, or Google.
Microsoft Azure Blog Storage Phishing Scam
One recent phishing scam uses Azure blob storage to obtain a valid SSL certificate for the phishing form. Blob storage can be used for storing a variety of unstructured data. While it is possible to use HTTP and HTTPS, the phishing campaign uses the latter, which will show a signed SSL certificate from Microsoft.
In this campaign, end users are sent an email with a button that must be clicked to view the content of a cloud-hosted document. In this case, the document appears to be from a Denver law firm. Clicking the button directs the user to an HTML page hosted on Azure blog storage that requires Office 365 credentials to be entered to view the document. Since the document is hosted on Azure blob storage, a Microsoft service, it has a valid SSL certificate that was issued to Microsoft adding legitimacy to the scam.
Entering login credentials into the form will send them to the attackers. The user will then be directed to another webpage, most likely unaware that they have been phished.
CloudFlare IPFS Gateway Abused
A similar campaign has been detected that abuses the CloudFlare IPFS gateway. Users can access content on the IPFS distributed file system through a web browser. When connecting to this gateway through a web browser, the HTML page will be secured with a CloudFlare SSL certificate. In this case, the login requires information to be entered including username, password, and recovery email address and phone number – which will be forwarded to the attacker, while the user will be directed to a PDF file unaware that their credentials have been stolen.
Office 365 Phishing Protections are Insufficient
Office 365 users are being targeted by cybercriminals as they know Office 365 phishing controls can be easily bypassed. Even with Microsoft’s Advanced Threat Protection for Office 365, phishing emails are still delivered. A 2017 study by SE Labs showed even with this additional anti-phishing control, Office 365 anti-phishing measures were only rated in the low-middle of the market for protection. With only the basic Exchange Online Protection, the protection was worse still.
Whether you run an SMB or a large enterprise, you are likely to receive high volumes of spam and phishing emails and many messages will be delivered to end users’ inboxes. Since the emails can be virtually impossible for end users to identify as malicious, it is probable that all but the most experienced, well trained, security conscious workers will be fooled. What is therefore needed is an advanced third-party spam filtering solution that will work alongside Office 365 spam filtering controls to provide far greater protection.
How to Make Office 365 More Secure
While Office 365 will block spam emails and phishing emails (Osterman Research showed it blocks 100% of known malware), it has been shown to lack performance against advanced phishing threats such as spear phishing.
Office 365 does not have the same level of predictive technology as dedicated on-premises and cloud-based email security gateways which are much better at detecting zero-day attacks, new malware, and advanced spear phishing campaigns.
To greatly improve protection what is needed is a dedicated third-party spam filtering solution for Office 365 such as SpamTitan. SpamTitan focuses on defense in depth, and provides superior protection against advanced phishing attacks, new malware, and sophisticated email attacks to ensure malicious messages are blocked or quarantined rather than being delivered to end users’ inboxes. Some of the additional protections provided by SpamTitan against Office 365 phishing attacks are detailed in the image below:

Managed service providers (MSPs) are discovering the huge potential for profit from offering security-as-a-service to their clients. Managed security services are now the biggest growth area for the majority of leading MSPs, with security-as-a-service well ahead of cloud migration, cloud management, and managed Office 365 services according to a recent survey conducted by Channel Futures.
Channel Futures conducted the survey as part of its annual MSP 501 ranking initiative, which ranks MSPs based on their ability to act on current trends and ensure they remain competitive in the fast-evolving IT channel market. The survey evaluated MSP revenue growth, hiring trends, workforce dynamics, service deliverables, business models, and business strategies.
The survey revealed that by far the biggest growth area is managed security services. Security-as-a-service was rated the biggest growth area by 73% of MSPs. 55% of MSPs said professional services were a major growth area, 52% said Office 365, and 51% said consulting services.
It is no surprise that security-as-a-service is proving so popular as the volume of attacks on enterprises and SMBs has soared. Cybercriminals are attacking enterprises and SMBs trying to gain access to sensitive data to sell on the black market. Attacks are conducted to sabotage competitors, nation-state-sponsored hackers are attempting to disrupt critical infrastructure, and data is being encrypted to extort money. There is also a thriving market for proprietary data and corporate secrets.
The cost of mitigating attacks when they succeed is considerable. For enterprises, the attacks can make a significant dent in profits, but cyberattacks on SMBs can be catastrophic. A study conducted by the National Cyber Security Alliance suggests as many as 60% of SMBs go out of business in the 6 months following a hacking incident.
Enterprises and SMBs alike have had to respond to the increased threat by investing heavily in security, but simply throwing money at security will not necessarily mean all security breaches are prevented. Companies need to employee skilled IT security professionals to implement, monitor and maintain those cybersecurity solutions, conduct vulnerability scans, and identify and address security gaps. Unfortunately, there is a major shortage of skilled staff and attracting the right talent can be next to impossible. Faced with major challenges, many firms have turned to MSPs to and have signed up for security-as-service offerings.
Forward-thinking MSPs have seized the opportunity and are now providing a comprehensive range of managed security services to meet the needs of their clients. They are offering a wide range of tools and services from phishing protection to breach mitigation services; however, for many MSPs, developing such a package is not straightforward.
Security-as-a-service is in high demand, but MSPs must be able to package the right services to meet customers’ needs and have a platform that can handle the business end. They too must attract the staff who can implement, monitor, and manage those services for their clients.
When devising a security-as-a-service offering, one option is to use a common security architecture for all clients and provide them with a range of solutions from the same provider. Many companies have implemented a slew of different security tools from multiple providers, only to discover they are still experiencing breaches. It is a relatively easy sell to get them to move over to a system where all the component parts are seamlessly integrated and to benefit from an MSP’s expertise in managing those solutions. There is a risk of course that clients will just choose to go direct rather than obtain those services from an MSP. This single platform strategy has been adopted by Liberty Technology – ranked 242 in the MSP 501 list – and is working well, especially for clients that have fewer than 1,000 employees.
At the other end of the spectrum is Valiant Technologies, ranked 206 in the MSP 501 list. Valiant has chosen a wide range of products from multiple cybersecurity solution providers and has built a unique package of products for its security service.
The products were chosen for the level of protection they offered and how well they work together. This approach has been a success for the firm. “Providing a bundle of offerings from different vendors that work well together is the most effective way for an MSP to retain its role as a trusted adviser,” said the firm’s CEO Tom Clancy. The security service has been added to other business services provided by the MSP and has proved to be an easy sell to clients.
ComTec Solutions, which ranked in position 248 in the MSP 501 list, is still deciding on the best way forward. The provision of security-as-a-service is a no brainer, but the company is currently assessing whether it is worthwhile building a security operations center (SOC) and becoming a managed security service provider (MSSP) or outsourcing the SOC service.
There are several different approaches to take when developing a managed security service offering. What is vital is that such a service is provided. The MSP 501 survey has shown that the most successful MSPs have responded to demand and are now helping their clients secure their networks through their security-as-a-service offerings. Those MSPs are clearly reaping the rewards.
If you are an MSP that is considering developing a security-as-a-service offering, be sure to speak to TitanHQ about its world-class cloud-based security solutions for MSPs – WebTitan and SpamTitan – and find out how they can be integrated into your security stack.
A new Python-based form of ransomware has been detected that masquerades as Locky, one of the most widely used ransomware variants in 2016. The new ransomware variant has been named PyLocky ransomware by security researchers at Trend Micro who have observed it being used in attacks in Europe, particularly France, throughout July and August.
The spam email campaigns were initially sent in relatively small batches, although over time the volume of emails distributing PyLocky ransomware has increased significantly.
Various social engineering tactics are being used by the attackers to get the ransomware installed, including fake invoices. The emails intercepted by Trend Micro have included an embedded hyperlink which directs users to a malicious webpage where a zip file is downloaded. The zip file contains PyLocky ransomware which has been compiled using the PyInstaller tool, which allows Python applications to be converted to standalone executable files.
If installed, PyLocky ransomware will encrypt approximately 150 different file types including Office documents, image files, sound files, video files, databases, game files, archives, and program files. Files stored on all logical drives will be encrypted and the original copies will be overwritten. A ransom note is then dropped on the desktop which has been copied from the note used by the threat actors behind Locky, although the two cryptoransomware threats are unrelated. Ransom notes are written in French, English, Korean, and Italian so it is probable that the attacks will become more widespread over the coming weeks.
While Python is not typically used to create ransomware, PyLocky is not the only Python-based ransomware variant to have been created. Pyl33t was used in several attacks in 2017, and CryPy emerged in 2016. What makes the latest ransomware variant stand out is its anti-machine learning capabilities, which help to prevent analysis using standard static analysis methods.
The ransomware abuses Windows Management Instrumentation (WMI) to determine the properties of the system on which it is installed. If the total visible memory of a system is 4GB or greater, the ransomware will execute immediately. If it is lower than 4GB, the ransomware will sleep for 11.5 days – an attempt to determine if it is in a sandbox environment.
Preventing attacks requires a variety of cybersecurity measures. An advanced spam filtering solution such as SpamTitan will help to prevent the spam emails being delivered to end users’ inboxes. A web filter, such as WebTitan, can be employed to control the websites that can be accessed by end users and block malicious file downloads. Security awareness training will help to ensure that end users recognize the threat for what it is. Advanced malware detection tools are required to identify the threat due to its anti-machine learning capabilities.
There is no free decryptor for PyLocky. Recovery without paying the ransom will depend on a viable backup copy existing, which has not also been encrypted in the attack.
A spam email campaign is being conducted targeting corporate email accounts to distribute Loki Bot malware. Loki Bot malware is an information stealer capable of obtaining passwords stored in browsers, obtaining email account passwords, FTP client logins, cryptocurrency wallet passwords, and passwords used for messaging apps.
In addition to stealing saved passwords, Loki Bot malware has keylogging capabilities and is potentially capable of downloading and running executable files. All information captured by the malware is transferred to the attacker’s C2 server.
Kaspersky Lab researchers identified an increase in email spam activity targeting corporate email accounts, with the campaign discovered to be used to spread Loki Bot malware. The malware was delivered hidden in a malicious email attachment.
The intercepted emails included an ICO file attachment. ICO files are copies of optical discs, which are usually mounted in a virtual CD/DVD drive to open. While specialist software can be used to open these files, most modern operating systems have the ability to access the contents of the files without the need for any additional software.
In this case, the ICO file contains Loki Bot malware and double clicking on the file will result in installation of the malware on operating systems that support the files (Vista and later).
It is relatively rare for ICO files to be used to deliver malware, although not unheard of. The unfamiliarity with ICO files for malware delivery may see end users attempt to open the files.
The campaign included a wide range of lures including fake purchase orders, speculative enquiries from companies containing product lists, fake invoices, bank transfer details, payment requests, credit notifications, and payment confirmations. Well-known companies such as Merrill Lynch, Bank of America, and DHL were spoofed in some of the emails.
A separate and unrelated spam email campaign has been identified that is using IQY files to deliver a new form of malware known as Marap. Marap malware is a downloader capable of downloading a variety of different payloads and additional modules.
Upon installation, the malware fingerprints the system and gathers information such as username, domain name, IP address, hostname, language, country, Windows version, details of Microsoft .ost files, and any anti-virus solutions detected on the infected computer. What happens next depends on the system on which it is installed. If the system is of particular interest, it is earmarked for a more extensive compromise.
Four separate campaigns involving millions of messages were detected by researchers at Proofpoint. One campaign included an IQY file as an attachment, one included an IQY file within a zip file and a third used an embedded IQY file in a PDF file. The fourth used a Microsoft Word document containing a malicious macro. The campaigns appear to be targeting financial institutions.
IQY files are used by Excel to download web content directly into spreadsheets. They have been used in several spam email campaigns in recent weeks to install a variety of different malware variants. The file type is proving popular with cybercriminals because many anti-spam solutions fail to recognize the files as malicious.
Since the majority of end users would not have any need to open ICO or IQY files, these file types should be added to the list of blocked file types in email spam filters to prevent them from being delivered to end users’ inboxes.
Hotels, restaurants, and telecommunications companies are being targeted with a new spam email campaign that delivers a new form of malware called AdvisorsBot. AdvisorsBot is a malware downloader which, like many malware variants, is being distributed vis spam emails containing Microsoft Word attachments with malicious macros.
Opening an infected email attachment and enabling macros on the document will see Advisorsbot installed. Advisorsbot’s primary role is to perform fingerprinting on an infected device. Information will be gathered on the infected device is then communicated to the threat actors’ command and control servers and further instructions are provided to the malware based on the information gathered on the system. The malware records system information, details of programs installed on the device, Office account details, and other information. It is also able to take screenshots on an infected device.
AdvisorsBot malware is so named because the early samples of the malware that were first identified in May 2018 contacted command and control servers that contained the word advisors.
The spam email campaign is primarily being conducted on targets in the United States, although infections have been detected globally. Several thousands of devices have been infected with the malware since May, according to the security researchers at Proofpoint who discovered the new malware threat. The threat actors believed to be behind the attacks are a APT group known as TA555.
Various email lures are being used in this malware campaign to get the recipients to open the infected attachment and enable macros. The emails sent to hotels appear to be from individuals who have been charged twice for their stay. The campaign on restaurants uses emails which claim that the sender has suffered food poisoning after eating in a particular establishment, while the attacks on telecommunications companies use email attachments that appear to be resumes from job applicants.
AdvisorsBot is written in C, but a second form of the malware has also been detected that is written in .NET and PowerShell. The second variant has been given the name PoshAdvisor. PoshAdvisor is executed via a malicious macro which runs a PowerShell command that downloads a PowerShell script which executes shellcode that runs the malware in the memory without writing it to the disk.
These malware threats are still under development and are typical of many recent malware threats which have a wide range of capabilities and the versatility to be used for many different types of attack such as information stealing, ransomware delivery, and cryptocurrency mining. The malicious actions performed are determined based on the system on which the malware has been installed. If that system is ideally suited for mining cryptocurrency, the relevant code will be installed. If the business is of particular interest, it will be earmarked for a more extensive compromise.
The best form of defense against this campaign is the use of an advanced spam filtering solution to prevent the emails from being delivered and security awareness training for employees to condition them how to respond when such a threat arrives in their inbox.
The past year has seen a steady increase in the number of reported email account compromises, with the healthcare industry one of the main targets for hackers.
Some of those breaches have seen the protected health information of thousands of patients compromised, with the largest phishing attack in 2018 – The phishing attack on Boys Town National Research Hospital – seeing more than 105,000 patients’ healthcare information exposed. Due to reporting requirements under HIPAA, healthcare phishing attacks are highly visible, although email account compromises are occurring across all industry sectors and the problem is getting worse.
284% Increase in Email Account Compromises in a Year
The increase in successful phishing attacks has been tracked by Beazley, a provider of specialist insurance services. The company’s research shows the number of reported phishing attacks increased every quarter since Q1, 2017 when there were 45 reported breaches that involved email accounts being compromised. In Q2, 2018, there were 184 email account compromises reported. Between Q1, 2017 and Q1, 2018, the number of reported data breaches involving compromised email accounts increased by 284%.
Why are email account compromises increasing? What do hackers gain from accessing email accounts rather than say, gaining access to networks which store vast amounts of data?
It can take a significant amount of time and effort to identify a vulnerability such a missed patch, an exposed S3 bucket, or an unsecured medical device, and exploit it.
By comparison, gaining access to an email account is relatively easy. Once access is gained, accessing further email accounts becomes easier still. If a hacker can gain access to an email account with the right level of administrative privileges, it may be possible for the entire mail system of an organization to be accessed.
If a hacker can gain access to a single email account, the messages in the account can be studied to gain valuable information about a company, its employees, and vendors. The hackers can identify further targets within an organization for spear phishing campaigns – termed Business Email Compromise (BEC) attacks – and attacks on contractors and suppliers.
Once One Account is Breached, Others Will Follow
If an executive’s email account is compromised, it can be used to send requests for wire transfers to the accounts department, HR can be emailed requesting W2-Forms that contain all the information necessary for filing fake tax returns and for identity theft. Requests can be sent via email to redirect employees’ paychecks and phishing emails can be sent to other employees directing them to websites where they have to divulge their email credentials.
Figures from the FBI show just how lucrative these Business Email Compromise (BEC) phishing attacks can be. Since October 2013, more than $12.5 billion has been lost to BEC attacks, up from $5.3 billion in December 2016.
Once access to the email system is gained, it is much easier to craft highly convincing spear phishing emails. Past email conversations can be studied, and an individual’s style of writing emails can be copied to avoid raising any red flags.
Email Account Compromises Are Costly to Resolve
Beazley also notes that email account compromises are some of the costliest breaches to resolve, requiring many hours of painstaking work to manually checking each email in a compromised account for PII and PHI. One example provided involved a programmatic search of compromised email accounts to identify PHI, yet that search uncovered 350,000 documents that required a manual check. The cost of checking those documents alone was $800,000.
Beazley also notes that when investigating breaches, the breached entity often discovers that only half of the compromised email accounts have been identified. The data breaches are usually much more extensive than was initially thought.
Unfortunately, once access to a single email account is gained, it is much harder to prevent further email compromises as technological controls are not so effective at identifying emails sent from within a company. However, it is relatively easy to block the initial phishing attempt.
How to Prevent Email Account Compromises
Many companies fail to implement basic controls to block phishing attacks. Even when a phishing-related breach is experienced, companies often remain susceptible to further breaches. The Ponemon Institute/IBM Security Cost of a Data Breach study showed there is a 27.9% probability of a company experiencing a further breach in the 24 months following a data breach.
To prevent phishing attacks, companies need to:
Deploy an advanced spam filtering solution that blocks the vast majority of malicious messages
Provide ongoing security awareness training to all staff and teach employees how to identify phishing emails
Conduct regular phishing simulation exercises to reinforce training and condition employees to be more security aware
Implement two-factor authentication to prevent attempts to access email accounts remotely
Implement a web filter as an additional control to block the accessing of phishing websites
Use strong, unique passwords or passphrases to make brute force and dictionary attacks harder
Limit or prevent third party applications from connecting to Office 365 accounts, which makes it harder for PowerShell to be used to access email accounts for reconnaissance.
In recent weeks, several large healthcare data breaches have been reported that have seen cybercriminals gain access to employees’ email accounts and sensitive data, although the recently disclosed UnityPoint Health phishing attack stands out due to the huge number of individuals that have been impacted and the extent of sensitive data exposed.
UnityPoint Health is one of the largest healthcare systems serving Iowa residents. The Des Moines-based healthcare provider recently discovered that its employees have been targeted in a phishing campaign that has seen several email accounts compromised. Those email accounts contained the sensitive information of approximately 1.4 million patients.
That not only makes this the largest phishing incident to have been suffered by a U.S. healthcare provider in 2018, it is also the largest healthcare data breach of 2018 and one of the most serious phishing attacks and data breaches ever reported.
The UnityPoint Health phishing attack has seen highly sensitive data compromised, including names, addresses, health insurance information, medical record numbers, diagnoses, treatment information, lab test results, medications, providers, dates of service, Social Security numbers, driver’s license numbers and, for a limited number of patients, their payment card information.
The phishing emails were sent to employees between March 14 and April 3, 2018, although the breach was not detected until May 31. As is common in phishing attacks on businesses, access to email accounts was gained through the impersonation of a senior executive.
A series of spoofed emails were sent to employees that appeared to have come from a trusted executive’s email account. Employees who opened the email were instructed to click a link that required them to enter their email login information. That information was captured by the attackers who were then able to gain access to the employees’ email accounts.
The UnityPoint Health phishing attack potentially gave the hackers access to all the information stored in the compromised email accounts – Information that could be used for identity theft and fraud. It is unclear whether mailboxes were downloaded, although UnityPoint Health said its forensic investigation suggests that the primary goal was to divert payroll payments and to use account access to fool accounts department staff into making fraudulent wire transfers. It is unclear if any of those attempts succeeded.
This is also not the only UnityPoint Health phishing attack to be reported this year. In March, UnityPoint Health announced that 16,400 patients had been affected by a separate phishing attack that saw multiple email accounts compromised.
The latest incident has prompted the healthcare provider to implement new technology to detect phishing and BEC attacks, multi-factor authentication has been implemented, and additional security awareness training has been provided to employees. Credit monitoring and identify theft monitoring services have been offered to patients whose driver’s license or Social Security number has been exposed, and all patients have been notified by mail.
As the Ponemon Institute’s 2018 Cost of a Data Breach Study showed, the cost of these million-record+ data breaches is considerable. The average cost of such a breach was estimated to be around $40 million.
One of the world’s biggest shipping firms – Cosco – has experienced a ransomware attack that has seen its local email system and network telephone in the Americas taken out of action as the result of widespread file encryption.
The Cosco ransomware attack is believed to have been contained in the Americas region. As a precaution and to prevent further spread to other systems, connections to all other regions have been disabled pending a full investigation. A warning has also been issued to all other regions warning of the threat of attack by email, with the firm telling its staff not to open any suspicious email communications. IT staff in other regions have also been advised to conduct scans of their network with antivirus software as a precaution.
The attack started on Tuesday, July 24, and its IT infrastructure remains down; however, the firm has confirmed that that attack has not affected any of its vessels which continue to operate as normal. Its main business systems are still operational, although the operators of terminals at some U.S ports are experiencing delays processing documentation and delivery orders.
It would appear that the Cosco ransomware attack is nowhere near the scale of the attack on the world’s biggest shipping firm A.P. Møller-Maersk, which like many other firms, fell victim to the NotPetya attacks last year. In that case, while the malware appeared to be ransomware, it was actually a wiper with no chance of file recovery.
The attack, which affected more than 45,000 endpoints and 4,000 servers, is estimated to have cost the shipping company between $250 million and $350 million to resolve. All servers and endpoints needed to be rebuilt, and the firm was crippled for 10 days. In that case, the attack was possible due to an unpatched vulnerability.
Another major ransomware attack was reported last week in the United States. LabCorp, one of the leading networks of clinical testing laboratories in the United States, experienced a ransomware attack involving a suspected variant of SamSam ransomware. While the variant of ransomware has not been confirmed, LabCorp did confirm the ransomware was installed as a result of a brute force attack on Remote Desktop Protocol (RDP).
Labcorp was both quick to detect the attack and contain it, responding within 50 minutes, although 7,000 systems and 1,900 servers are understood to have been affected. It has taken several days for the systems to be brought back online, during which time customers have been experiencing delays obtaining their lab test results.
Several cybersecurity firms have reported that ransomware attacks are in decline, with cryptocurrency mining offering better rewards, although the threat from ransomware is still ever present and attacks are occurring through a variety of attack vectors – exploitation of vulnerabilities, brute force attacks, exploit kit downloads, and, commonly, through spam and phishing emails.
To protect against ransomware attacks, companies must ensure security best practices are followed. Patches must be applied promptly on all networks, endpoints, applications, and databases, spam filtering software should be used to prevent malicious messages from reaching inboxes, web filters used to prevent downloads of ransomware from malicious websites, and all staff should receive ongoing cybersecurity awareness training.
Additionally, systems should be implemented to detect anomalies such as excessing file renaming, and networks should be segmented to prevent lateral movement in the event that ransomware is deployed.
Naturally, it is also essential that data are backed up regularly to ensure recovery is possible without having to resort to paying the ransom demand. As the NotPetya attacks showed, paying a ransom to recover files may not be an option.
Rakhni ransomware, a malware variant first detected in 2013, has spawned many variants over the past three years and is still an active threat. Rakhni ransomware locks files on an infected device to prevent the user from accessing their data. A ransom demand is issued and if payment is made, the attackers will supply the keys to unlock the encryption. If the ransom is not paid the files will remain encrypted. In such cases, the only option for file recovery is to restore files from backups.
Now the developers of Rakhni ransomware have incorporated new functionality. Checks are performed on an infected device to determine whether it has sufficient processing power to be used as a cryptocurrency mining slave. If so, cryptocurrency mining malware will be downloaded. If not, ransomware will be deployed.
This new development should not come as a major surprise. The massive rise in the value of many cryptocurrencies has made mining cryptocurrencies far more profitable for cybercriminals than ransomware. When ransomware is installed, many victims choose not to pay and instead recover files from backups. Infection is no guarantee that a payment will be received. If a cryptocurrency miner can be installed, it gets straight to work generating money for the attackers. Ransomware attacks are still a major threat, although many cybercriminals have switched their operations to mining cryptocurrencies. In fact, cryptocurrency mining malware attacks are now much more common than ransomware attacks.
However, not all computers have sufficient CPU processing power to make cryptocurrency mining worthwhile, so the method used by the threat actors behind Rakhni ransomware helps them maximize their profits.
The new Rakhni ransomware campaign was detected by researchers at Kaspersky Lab. The malware used is Delphi-based and is being distributed in phishing emails containing a Microsoft Word file attachment.
The user is advised to save the document and enable editing. The document contains a PDF file icon which, if clicked, launches a fake error message suggesting the DLL file required to open the PDF file has not been found. The user needs to click on the OK box to close the error message.
When the error box is closed, the malware performs a series of checks on the machine to identify the processes running on the device and assesses those processes to determine if it is running in a sandbox environment and the likelihood of it being able to run undetected. After these checks have been performed the system is assessed to determine its capabilities.
If the machine has more than two processors and does not have a Bitcoin folder in the AppData folder, a cryptocurrency miner will be installed. The cryptocurrency miner uses fake root certificates which show the program has been issued by Microsoft Corporation to help disguise the miner as a trusted application.
If a Bitcoin folder does exist, certain processes will be stopped, and Rakhni ransomware will be downloaded and run. If there is no Bitcoin folder and only one processor, the malware will use its worm component and twill attempt to spread to other devices on the network where the process starts over.
Advanced anti-virus software can provide protection against this attack, while spam filtering solutions can prevent the phishing emails from being delivered to end users. Businesses should also ensure that their employees are made aware of the risk of these types of attacks through security awareness training. Employees should be instructed never to open attachments in emails from unknown senders and taught the warning signs of a potential attack in progress. Naturally, good data backup practices are essential to ensure that if all other controls fail, files can be recovered without paying a ransom.
A major Children’s Mercy Hospital phishing attack has highlighted the importance of implementing effective spam filtering controls and the need to provide security awareness training to end users.
Phishing is a method of fraudulently obtaining sensitive information through deception. While attacks can occur over the telephone, via social media sites, or through text messages and chat platforms, the most common attack vector is email.
Convincing emails are sent to end users urging them to open an email attachment or to click on a malicious link. Attachments are used to install malware, either directly through malware attached to the email, or more commonly, using macros or other malicious code in documents which download scripts that in turn download the malicious payload.
In the case of embedded hyperlinks in emails, they typically direct an end user to a website that asks them to login. The website could ask for their email credentials, appear to be a Google login box, Dropbox login page, or other file sharing platform. Disclosing login credentials on that webpage sends the information to the attackers. These login pages are convincing. They look exactly like the sites that they are spoofing.
That was the case with the Children’s Mercy Hospital phishing attack. The Kansas City, MO, hospital received several phishing emails which directed employees to fake login pages on criminally-controlled websites.
The phishing attack occurred on or shortly before December 2, 2017. On Dec 2, Children’s Mercy’s security team identified authorized access to two employees’ email accounts. Access to the accounts was blocked the same day and the passwords were reset. Two weeks later, on December 15 and Dec 16, two further email accounts were accessed by unauthorized individuals. Again, unauthorized access was detected and blocked the same day. A fifth email account was accessed on January 3, 2018 with access blocked the following day.
The prompt action in response to the Children’s Mercy phishing attack limited the potential for those email accounts to be abused. When criminals gain access to email accounts they often use them to send further phishing emails. Since those emails come from a legitimate email account, the recipients of the messages sent from that account are more likely to open the emails as they come from a trusted source. That is why business email compromise scams are so effective – because employees trust the sender of the email and take action as requested in the belief that they are genuine communications.
In the case of the Children’s Mercy phishing attack, the criminals acted quickly. Following a forensic investigation into the attacks, Children’s Mercy discovered on January 19, 2018, that even though access to the accounts was promptly blocked, the attackers had successfully downloaded the mailboxes of four of the five employees. The messages contained a wide range of protected health information (PHI) of 63,049 patients.
The PHI included information such as name, gender, age, height, weight, BMI score, procedure dates, admission dates, discharge dates, diagnosis and procedure codes, diagnoses, health conditions, treatment information, contact details, and demographic information.
While Social Security numbers, insurance information, and financial data were not obtained – information most typically required to commit fraud – such detailed information on patients could be used in impersonation attacks on the patients. It would be quite easy for the attackers to pretend they were from the hospital and convince patients to provide their insurance information for example, which could then be used for medical identity fraud.
Due to the scale of the attack and number of emails in the compromised accounts, it has taken a considerable time to identify the individuals affected. The Kansas City Star reports that some patients are only just being notified.
In response, the hospital implemented 2-factor authentication and other technical controls to prevent further attacks.
2-factor authentication is an important security measure that provides protection after a phishing attack has occurred. If login credentials are supplied, but the location or the device used to access the account is unfamiliar, an additional method of authentication is required before access to the account is granted – a code sent to a mobile phone for example.
Two of the most effective security controls to prevent credential theft via phishing are spam filters and security awareness training.
An advanced spam filter is an essential security measure to block phishing attacks. The changing tactics of cybercriminals means no spam filtering solution will be able to block every single phishing email, although SpamTitan, a highly effective spam filtering solution with advanced anti-phishing protections, blocks more than 99.97% of spam and malicious emails to ensure they do not arrive in end users’ inboxes.
Security awareness training helps to prevent employees from clicking on the small percentage of messages that get past perimeter defenses. Employees need to be trained to give them the skills to identify phishing attempts and report them to their security teams. An ongoing training program, with phishing simulation exercises, will help to condition employees to recognize threats and respond appropriately. Over time, phishing email detection skills will improve considerably.
An effective training program can limit the number of employees that respond to phishing attacks, either preventing the attackers from gaining access to email accounts or severely limiting the number of employees who respond and disclose their credentials.
The Children’s Mercy phishing attack is one of many such attacks on healthcare organizations and businesses, and as those attacks increase and more data is obtained by criminals, implementing advanced phishing protections has never been more important.

The FBI has published its 2017 Internet Crime Report, which details the main types of online crime reported to its Internet Crime Complaint Center (IC3).
In 2017, businesses and consumers reported 301,580 incidents to IC3 and more than $1.4 billion was lost to cybercriminals. Of course, these are only reported losses. Many Internet crimes go unreported, so the true losses are likely to be substantially higher.
2017 saw more complaints of Internet crime than any other year since 2013 when the reports first started to be published.
Identity theft and corporate data breaches often make the headlines, although by far the biggest area of criminal activity are business email compromise (BEC) scams – or email account compromise (EAC) when the scams target individuals.
Business Email Compromise Scams – The Main Cause of Losses in 2017
More than three times as much money was lost to BEC and EAC scams than the next highest cause of losses: confidence fraud/romance scams. In 2017, the reported losses from BEC/EAC scams was $676,151,185.
Business email compromise and email account compromise scams involve the use of a compromised email account to convince individuals to make transfers of funds to accounts controlled by criminals or to send sensitive data via email.
BEC scams usually start with compromising the email account of the CEO, CFO or another board member – which is why this type of scam is also known as CEO fraud. Access to the executive’s email account is gained via brute force guessing of passwords or, most commonly, social engineering techniques and phishing scams.
Once access to the email account is gained, an email conversation is initiated with another member of the workforce, typically an individual responsible for making wire transfers. That individual is instructed to make a transfer to a new bank account – that of the attacker. Alternatively, the data of employees is requested – W2 Forms – or other sensitive company information. These scams often involve large transfers of funds. In 2017 there were 15,690 such scams reported to IC3, making the average loss $43,094.
Phishing Extensively Used in Internet Crime
Phishing, vishing, smishing and pharming were grouped together. They ‘only’ resulted in losses of $29,703,421, although the losses from these crimes are difficult to calculate accurately. The losses associated with phishing are grouped in many other categories. BEC scams often start with a phishing attack and research from Cofense suggests 91% of corporate data breaches start with a phishing email.
The 2017 Internet Crime Report reveals the extent to which phishing is used in cyberattacks. There were 25,344 phishing incidents reported to IC3 in 2017 – the third highest category of Internet crime behind non-payment/non-delivery and personal data breaches. Many personal data breaches start with a phishing email.
Ransomware Attack Mitigation Proves Expensive
In addition to the threat of BEC attacks, the FBI’s 2017 Internet Crime Report warns of the threat from ransomware. Ransomware only resulted in reported losses of $2.3 million and attracted 1,783 complaints, although it is worthy of a mention due to the considerable disruption that attacks can cause. The reported losses – in terms of the ransoms paid – may be low, but actual losses are substantially higher. The ransomware attack on the City of Atlanta in April 2018 saw a ransom demand of $52,000 issued, although the actual cost of mitigating the attack was reported to be at least $2.7 million in April. However, in June 2018, city Information Management head Daphney Rackley indicated a further $9.5 million may be required over the coming year to cover the cost of mitigating the attack.
Tech Support Fraud Losses Increased by 90%
Another hot topic detailed in the 2017 Internet Crime Report is tech support fraud – This is a widespread scam where individuals are fooled into thinking they have a computer problem such as a virus or malware installed, when they do not. Calls are made warning of detected malware, and users are directed to malicious websites via phishing emails where pop-up warnings are displayed, or screen lockers are used.
These scams usually require the victim to pay the scammer to remove a fictitious infection and provide them with remote access to a computer. In addition to the scammers charge for removing the infection, sensitive data such as usernames, passwords, Social Security numbers, and bank account information are often stolen. 2017 saw a 90% increase in losses from tech support scams.
Protecting Against Internet Crime
One of the most important defenses for businesses to implement to protect against the leading cause of financial losses is an advanced spam filtering solution. Business email compromise scams often start with a phishing email and effective spam filtering will reduce the potential for email accounts to be compromised. Ransomware and malware are also primarily distributed via email. An advanced spam filter such as SpamTitan will block 100% of all known malware and prevent malicious messages from being delivered to inboxes.
Security awareness training is also essential. Malicious messages will make it past spam filtering solutions on occasion, so it is important for all end users to be prepared for malicious messages and taught security best practices. Training should be provided to every individual in the company with a corporate email account or access to an Internet facing computer, including board members.
A web filtering solution is also an important consideration. A web filter is an additional anti-malware control that can be used to prevent employees from visiting malicious websites – either via links in emails, redirects, or through general web browsing. A web filter, such as WebTitan, will block ransomware and malware downloads and prevent end users from accessing the types of phishing websites used to initiate BEC attacks.
These three cybersecurity measures should be part of all organizations’ cybersecurity defenses. They will help to prevent businesses from being included in next year’s FBI Internet Crime Report.
UK users are being targeted with a fake WannaCry ransomware alert threatening file encryption if a ransom demand is not paid.
Fraudsters Claim WannaCry is Back!
In May last year, WannaCry ransomware attacks brought many companies to a standstill, with the UK’s National Health Service (NHS) a notable victim. Now, a little more than a year later, a new WannaCry ransomware campaign is being run, or so the sender of a batch of phishing emails claims.
Email recipients are told “WannaCry is back!” and are warned that their devices have been hacked and ransomware has been installed.
Email recipients are warned that the threat actors have perfected their ransomware and this time around antivirus software and firewalls will not prevent file encryption. Further, recovery will not be possible if the ransom is not paid.
Failure to pay, or any attempt to try to remove the ransomware without paying the ransom demand will result in permanent file deletion. Further, the ransomware can propagate and infect the local network, cloud data, and remote devices, regardless of operating system.
Email recipients are told that the ransomware has already been deployed and payment of a ransom of 0.1 Bitcoin – Around $650 – must be made to stop the attack. Email recipients are given just 24 hours to pay the ransom before data are permanently deleted.
The email is signed by WannaCry-Hack-Team, and so far, more than 300 copies of the message have been reported to the UK government’s National Fraud and Cyber Crime Reporting Centre, Action Fraud.
A Phishing Scam that Preys on WannaCry Fears
There are some signs that the email is not a genuine threat, and instead is just preying on fears about another WannaCry style attack.
Ransomware attackers encrypt data then ask for a ransom to unlock files. They do not send a warning saying they will encrypt data if a ransom is not paid. That tactic may be used by some DDoS attackers, but not by ransomware threat actors.
Email recipients are told that this version of WannaCry will work on “any version of Windows, iOS, Android, and Linux.” The original version of WannaCry took advantage of a vulnerability in Windows Server Message Block. WannaCry only affected vulnerable Windows devices that had not been patched. The ransomware was not a threat on other operating systems.
Phishing campaigns often include spelling mistakes in the subject line and message body and this email is no different. The subject line is – “Attantion WannaCry”.
This is simply a phishing campaign that attempts to extort money from the recipient. No ransomware has been installed and the attackers cannot encrypt any files.
If you receive such a message threatening file encryption unless you pay a ransom, report the message to Action Fraud (UK), US-CERT (firstname.lastname@example.org) in the United States, or the government Fraud and Cyber Crime agency in your country of residence and delete the email and do not pay any Bitcoin ransom.
Of course, not all ransomware threats are as benign as this and many attackers will be able to encrypt your data. To protect against real ransomware threats ensure you create multiple backups of your files, deploy a spam filtering solution, ensure your operating system and all software are kept up to date, and keep your anti-virus protection up to date.
