Phishing and email spam is estimated to cost industry more than $1 billion each year, and cybercriminals are becoming more sophisticated in the campaigns they launch to try to extract confidential data or passwords from unsuspecting Internet users.
Part of the reason why phishing and email spam continue to work is the language used within the communication. The message to “Act Now” because an account seems to have been compromised, or because a colleague appears to need urgent support, often causes individuals to act before they think.
Even experienced security experts have been caught by phishing and email spam, and the advice provided to every Internet user is:
If you are unsure of whether an email request is legitimate, try to verify it by contacting the sender independently of the information provided in the email.
Never reveal confidential data or passwords requested in an email or on a web page you have arrived at after following a link in an email.
Enable spam filters on your email, keep your anti-virus software up-to-date and enable two-step authentication on all your accounts whenever possible.
Always use different passwords for different accounts, and change them frequently to avoid being a victim of key-logging malware downloads.
Remember that phishing and email spam is not limited to email. Watch out for scams sent via social media channels.
Phishing in particular has become a popular attack vector for cybercriminals. Although phishing goes back to the early days of AOL, there has been a tenfold increase in phishing campaigns over the past decade reported to the Anti-Phishing Working Group (APWG).
Phishing is an extension of spam mail and can target small groups of people (spear phishing) or target executive-level management (whale phishing) in order to collect information or gain access to computer systems.
The best way to protect yourself from phishing and email spam is to follow the advice provided above and – most importantly – enable a reputable spam filter to block potentially unsafe emails from being delivered to your inbox.
Cybercriminals are constantly coming up with new scams to convince people to part with their login credentials or install botnets, viruses, malware, or ransomware.
Email is one of the easiest ways to get these scams out to the masses, accompanied with a good hook to get the user to open the message. Various tactics are used to achieve the latter, one of the most common being fear. Scaring people into taking action is very effective. A recently identified campaign is a good example. It uses fear of a flu pandemic to get users to take action.
According to the U.S. Centers for Disease Control and Prevention, flu killed about 80,000 in the 2017 to 2018 season, which was a record year for flu deaths. The previous record in the past three decades was beaten by 24,000.
For any phishing email to stand a good chance of fooling large numbers of people, the emails must be credible. This campaign provides that credibility by spoofing the CDC. The subject lines used in the campaign warn of a flu pandemic, and the email addresses used and the logos in the message body make the messages appear to have genuinely been sent by the CDC.
The message included an attachment – named Flu Pandemic Warning – provides important information that users need to know to prevent infection and stop the disease from spreading. The fear of contracting flu combined with the realistic looking emails make it likely that this campaign will fool many individuals.
That document contains malicious code that downloads and runs GandCrab ransomware v5.2, for which there is currently no free decryptor. Once downloaded, GandCrab ransomware will encrypt files on the infected computer preventing them from being accessed. The average ransom demand is $800 per infected computer.
In order for the malicious code to download the ransomware, the content must be enabled. In the message body, recipients are told that in order to view all the information in the document they must enable content. This prior instruction is intended to get the user to click ‘enable content’ quickly when the document is opened, rather than to stop and think.
All users should be alert to these kind of email scams. Caution should be exercised before opening any email attachment, no matter how urgent the message appears to be. Any unsolicited email should be carefully checked as there will usually be signs that indicates all is not what it seems.
Businesses are particularly at risk and can suffer major losses as a result of ransomware attacks, especially when several employees are fooled by these email scams.
Signature-based email defenses were once effective at blocking malware, but malware developers are constantly releasing new versions that have never before been seen. Signature-based AV software struggles to maintain pace and is not effective against zero-day malware variants and malicious code that downloads the malware.
End user training certainly goes a long way and can help to prevent mass infections, but what is really needed is an advanced anti-phishing solution that blocks phishing emails and email scams at source before they are delivered to inboxes. That is an area where TitanHQ can help.
To protect against email-based attacks, TitanHQ developed SpamTitan – A highly effective anti-phishing and anti-spam solution with advanced features that provide superior protection against phishing and malware attacks.
In addition to dual anti-virus engines, SpamTitan incorporates a wide range of checks to distinguish malicious emails from genuine messages. Recently, Spamtitan has had two new features incorporated: DMARC email authentication and sandboxing. DMARC helps to ensure that spoofed email messages, such as those that appear to have been sent by the CDC, are identified as scams and are blocked. Sandboxing is important for protecting against zero-day malware threats and malicious downloaders.
Potentially malicious attachments are executed and analyzed in a Bitdefender-powered sandbox, where the actions performed by malware and malicious code can be assessed without causing harm. When malicious code is detected it is blocked across all users’ inboxes.
With SpamTitan in place, businesses will be well protected against campaigns such as this.

SpamTitan, TitanHQ’s business email security solution, has been named leader in the Spring G2 Crowd Grid Report for Email Security Gateways.
G2 Crowd is a peer-to-peer review platform for business solutions. G2 Crowd aggregates user reviews of business software and the company’s quarterly G2 Crowd Grid Reports provide a definitive ranking of business software solutions.
The amalgamated reviews are read by more than 1.5 million site visitors each month, who use the reviews to inform software purchases. To ensure that only genuine reviews are included, each individual review is subjected to manual review.
The latest G2 Crowd Grid Report covers email security gateway solutions. Gateway solutions are comprehensive email security platforms that protect against email-based attacks such as phishing and malware. The email gateway is a weak point for many businesses and it is one that is often exploited by cybercriminals to gain access to business networks. A powerful and effective email gateway solution will prevent the vast majority of threats from reaching end users and will keep businesses protected.
To qualify for inclusion in the report, email gateway solutions needed to scan incoming mail to identify spam, malware, and viruses, securely encrypt communications, identify and block potentially malicious content, offer compliant storage through archiving capabilities, and allow whitelisting and blacklisting to control suspicious accounts.
For the report, 10 popular email security gateway solutions were assessed from Cisco, Barracuda, Barracuda Essentials, Proofpoint, Mimecast, Symantec, McAfee, Solarwinds MSP, MobileIron, and TitanHQ. Customers of all solutions were required to give the product a rating in four areas: Quality of support, ease of use, meets requirements and ease of administration.
TitanHQ the leader in business email security, today announced it has been recognized as a leader in the G2 Crowd Grid? Spring 2019 Report for Email Security.
TitanHQ’s SpamTitan was named leader based on consistently high scores for customer satisfaction and market presence. 97% of users of SpamTitan awarded the solution 4 or 5 stars out of 5 and 92% said they would recommend SpamTitan to others.

Emotet malware was first identified in 2014 and its original purpose was to obtain banking credentials and other sensitive information; however, the malware is regularly updated and new functionality is added. Emotet malware is now one of the most prevalent and dangerous malware threats faced by businesses.
The malware can detect whether it is running in a virtual environment and will generate false indicators in such cases. The malware is polymorphic, which means it changes every time it is downloaded. That makes it difficult to detect using the signature-based detection methods employed by standard anti-virus software.
The malware also has worm-like features which allows it to rapidly spread to other networked computers. Emotet is also capable of spamming and forwarding itself to email contacts. As if infection with Emotet is not bad enough, it can also download other malware variants onto infected devices.
Emotet malware is one of the most destructive malware variants currently in use and cleaning up Emotet attacks can be incredibly costly. The Department of Homeland Security has reported that some attacks on state, local, tribal, and territorial governments have cost more than $1 million to resolve.
Emotet malware is primarily distributed via spam email, either through malicious attachments or hyperlinks to websites where the malware is silently downloaded. The lures used in the messages are highly varied and include most of the commonly used phishing lures such as shipping notifications, fake invoices, payment requests, PayPal receipts.
Now the threat actors behind the malware have adopted a new tactic to increase infection rates. Once installed on a device, the malware accesses email conversation threads and forwards the message to individuals named in the thread.
The original email conversation is unaltered, but a hyperlink is added to the top of the message. The link directs the recipient to a webpage where a file download is triggered. Opening the document and enabling macros will see Emotet downloaded. Email attachments may also be added to previous conversation threads in place of hyperlinks.
Since the messages come from a known individual with whom an email conversation has taken place in the past, the probability of the document being opened is greater than if messages come out of the blue or are sent from an unknown individual.
Several cybersecurity firms have identified a campaign using this tactic, including phishing intelligence provider Cofense and security researcher Marcus Hutchins (MalwareTech).
The current campaign uses revived conversations from before November 2018, although more recent conversations may be revived in further campaigns. Any revived old email conversation that contains a link or an attachment could indicate a user has been targeted and that at least one member of the email exchange has been infected with Emotet.
The current campaign is not only extensive, it is also proving to be extremely successful. Spamhaus reports that there have been 47,000 new infections in the past two months alone, while Cofense reports that it has identified more than 700,000 infections in the past 12 months.
Protecting against this dangerous malware requires a powerful anti-spam solution and good security awareness training for staff. SpamTitan’s new features can help to detect malicious emails spreading Emotet malware to better protect businesses from attack.

Monday April 15 is Tax Day in the United States – the deadline for submitting 2018 tax returns. Each year in the run up to Tax Day, cybercriminals step up their efforts to obtain users’ tax credentials. In the past few weeks, many tax-related phishing scams have been detected which attempt to install information stealing malware.
One of the main aims of these campaigns is to obtain tax credentials. These are subsequently used to file fraudulent tax returns with the IRS. Tax is refunded to accounts controlled by the attackers, checks are redirected, and a range of other methods are used to obtain the payments.
Attacks on tax professionals are commonplace. If access can be gained to a tax professional’s computer, the tax credentials of clients can be stolen, and fraudulent tax returns can be filed in their names. A single successful attack on a tax professional can see the attacker obtain many thousands of dollars in tax rebates.
There has been the usual high level of tax-related phishing scams during the 2019 tax season and businesses of all types have been targeted. It is not only tax credentials that cybercriminals are after. Many tax-themed phishing scams have been conducted which attempt to install malware and ransomware such as the TrickBot banking Trojan.
The TrickBot banking Trojan is a powerful malware variant which, once installed, can give an attacker full control of an infected computer. The malware is primarily an information stealer. A successful installation on one business computer can allow the attackers to move laterally and spread the malware across the whole network.
The primary purpose of the TrickBot trojan is to steal banking credentials which can be used to make fraudulent wire transfers: however, TrickBot is regularly updated with new features. In addition to stealing banking credentials, the malware can steal VNC. RDP, and PuTTY credentials.
The threat actors behind TrickBot are highly organized and well resourced. More than 2,400 command and control servers are used by the cybercriminal gang and that number continues to grow.
The three new TrickBot malware campaigns were detected since late January by IBM X-Force researchers. Spam email messages are carefully crafted to appear legitimate and look innocuous to business users and appear to have been sent by well-known accounting and payroll firms such as ADP and Paychex.
Spoofed email addresses are commonly used, although in these campaigns, the attackers have used domain squatting. They have registered domains that are very similar to those used by the accounting firms. The domains have transposed letters and slight misspellings to make the email appear to have been sent from a legitimate source. The domains can be highly convincing and, in some cases, are extremely difficult to identify as fake.
The emails are well written and claim to include tax billing records, which are included as attached spreadsheets. The spreadsheets contain malicious macros which, if allowed to run, will download the TrickBot Trojan.
To prevent attacks, several steps should be taken. Macros should be disabled by default on all devices. Prompt patching is required to keep all software and operating systems up to date to prevent vulnerabilities from being exploited.
End users should receive security awareness training and should be taught cybersecurity best practices and how to identify phishing emails. An advanced spam and anti-phishing solution should also be implemented to ensure phishing emails are identified and prevented from reaching end users inboxes. Further, all IoCs and IPs known to be associated with the threat actors should be blocked through spam filtering solutions, firewalls, and web gateways.
The latter is made easy with SpamTitan and WebTitan – TitanHQ’s anti-phishing and web filtering solutions for SMBs.
Current users of the SpamTitan email security solution and SMBs and MSPs that are considering implementing SpamTitan or offering it to their clients are invited to join a webinar in which TitanHQ will explains the exciting new features that have recently been incorporated into the anti-phishing and anti-spam solution.
SpamTitan has recently received a major update that has seen the incorporation of DMARC email authentication to better protect users from email impersonation attacks and the addition of a new Bitdefender-powered sandbox. The sandbox allows users to safely assess email attachments for malicious actions, to better protect them against zero-day malware and other malicious software delivered via email.
The webinar will explain these and other features of SpamTitan in detail and the benefits they offer to customers, including how they better protect SMBs and SMEs from phishing, spear phishing, spoofing, ransomware, malware, and zero-day attacks.
The webinar will also explain why SpamTitan is the leading email security solution for managed service providers serving the SMB and SME market and how the solution can help to enhance security for their clients and can easily be slotted into their service stacks.
The webinar will be taking place on Thursday April 4, 2019 at 12pm, EST and will last approximately 30 minutes.
The past few weeks have seen two major disasters in which hundreds of people lost their lives. 157 people lost their lives in the Ethiopian Airlines Boeing 737 Max crash and the Christchurch mosque massacre saw 50 people killed.
Both events were terrible tragedies that shocked people the world over. Victims and their families have been receiving messages of support on social media and many people have shown their support by making financial donations. More than US$5 million has so far been raised to help the victims of the New Zealand attack.
Unfortunately, cybercriminals are taking advantage. In the past few days, phishing campaigns have been detected that are using the tragedies to infect computers with malware and steal charitable donations.
According to New Zealand’s cybersecurity agency, CERT NZ, multiple campaigns have been detected that are using the Christchurch attack as a lure. Malware has been embedded in video footage of the tragedy which is currently being shared online, including on social media websites.
Phishing attacks are also being conducted which contain links to faked online banking forms that attempt to obtain users banking credentials. One campaign spoofed the Westpac New Zealand bank and emails appeared to have been sent from its domain. Other email campaigns contain pleas for financial assistance and supply bank account details for donations, but the details are for criminal-controlled accounts.
Another campaign has been detected that is using the Ethiopian Airlines Boeing 737 Max crash to spread a remote access Trojan and information stealer. The emails claim to offer information to air travelers about airlines that are likely to also suffer crashes. The emails offer information that has been found on the darkweb by a security analyst. The emails include a JAR file which, it is claimed, has important information for all air travelers on airlines to avoid due to the risk of plane crashes.
Whenever there is a tragedy that is extensively covered in the media cybercriminals try to take advantage. By adopting cybersecurity best practices such as never opening email attachments from unknown senders nor clicking links in emails, these scams can be avoided.
Unfortunately, email spoofing makes it difficult to detect phishing threats. Scam emails often appear genuine and seem to have been sent from a trusted source. To combat the threat to businesses, TitanHQ has recently updated its spam filtering solution, SpamTitan, to provide greater protection from these threats.
SpamTitan now incorporates DMARC to authenticate senders of emails and protect against email impersonation attacks. To provide even greater protection from malware, in addition to dual anti-virus engines, SpamTitan now incorporates a Bitdefender-powered sandbox, where suspicious files can be safely analyzed to determine whether they are malicious.
These additional controls will help to protect businesses and end users from new malware threats and advanced phishing and email impersonation scams.
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 email@example.com 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.
The massive Allscripts EHR breach in January 2018 resulted in massive disruption for the company and its clients. Clients were locked out of their electronic health records for several days while the company battled to recover from the attack. Around 1,500 of the company’s clients were affected.
The cost of mitigating the ransomware attack was considerable, and in addition to those costs, the Allscripts EHR breach prompted many clients to take legal action. The costs continue to mount.
The Allscripts EHR breach involved SamSam ransomware, which has plagued the healthcare industry over the past couple of years. The threat actors behind the attacks typically gain access to healthcare networks through RDP vulnerabilities and deploy the ransomware manually after scouting the network. This way, maximum damage can be inflicted, which increases the probability of the ransom being paid.
The Allscripts EHR breach certain stands out as one of the most damaging ransomware attacks of 2018, although it was just one of many healthcare ransomware attacks in 2018 involving many ransomware variants.
According to Beazley Breach Response Services, ransomware attacks more than doubled in September. Many cybercriminals have switched to cryptocurrency mining malware, but the ransomware attacks on healthcare organizations are continuing and show no sign of slowing.
In recent months, there has been a growing trend of combining malware variants to maximize the profitability of attacks. Ransomware is a quick and easy way for cybercriminals to earn money but combining ransomware with other malware variants is much more profitable. Further, if files are recovered from backups and no ransom is paid, cybercriminals can still profit from the attacks.
Several campaigns have been detected recently that combine Trojans such as AZORult, Emotet and Trickbot with ransomware. Attacks with these Trojans have increased by 132% since 2017 according to Malwarebytes. The Trojans steal sensitive information through keylogging, are capable lateral movement within a network, and also serve as downloaders for other malware such as Ryuk and GandCrab ransomware. Once information has been stolen, the ransomware payload is deployed.
The Allscripts EHR breach was somewhat atypical. It is far more common for ransomware to be delivered via email than brute force attacks on RDP. The campaigns combining Emotet, Trickbot, and AZORult with ransomware are primarily delivered by email.
In addition to ransomware attacks, phishing attacks are rife in healthcare. Email was the most common location of exposed protected health information in 2018. Email security is a weak point in healthcare defenses.
The number of successful ransomware and phishing attacks in healthcare make it clear that email security needs to improve. An advanced spam filter to block malicious emails, improved end user training is required to teach employees how to recognize email threats, intrusion detection systems need to be deployed, along with powerful anti-virus solutions. Only by implementing layered defenses to block email attacks and other attack vectors will healthcare organizations be able to reduce the risk of ransomware attacks.
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 phishing scam has been detected that uses a novel method to evade detection – The use of custom fonts to implement a substitution cipher that makes the source code of the phishing kit appear normal.
When users visit the phishing website they are presented with the logos and standard login page of their bank. To the user, apart from the domain name, there is nothing to indicate that the site is not genuine. As with similar phishing scams, if the user enters their credentials they will be harvested by the scammer and used to gain access to the users’ bank account.
These types of phishing scams are now commonplace, although the latest campaign has an interesting twist – one that make it much harder to detect the site as malicious.
Many phishing kits obfuscate their source code to make it harder to determine what it does. One method that has been used in the past is the use of substitution functions to make the sites harder to detect. This technique substitutes individual letters such as abcd with alternate letters jehr for example. While the page is rendered correctly for the user, when a program reads the source code it is presented with jumbled, gibberish letters.
The result is users see a standard banking login page as does software than scans the site. Further, as an additional measure to avoid detection, the branding that has been stolen from the targeted bank is also obfuscated. It is common for bank logos to be stolen and included on phishing pages to convince visitors they are on the genuine site, but the use of the logos can be detected. By rendering the graphics using scalable vector graphics files, the logos and their source do not appear in the source code of the page.
These tactics could easily be used to target finance department employees and fool them into disclosing their corporate banking credentials, allowing business accounts to be plundered.
These new techniques show just how important it is to block phishing emails at source before they are delivered to end users’ inboxes and the need for comprehensive cybersecurity training to be provided to employees to help them identify potentially malicious emails.
2-factor authentication is an important safeguard to prevent unauthorized account access, but does 2-factor authentication stop phishing attacks?
What is 2-Factor Authentication?
2-Factor authentication is commonly used as an additional protection measure to prevent accounts from being accessed by unauthorized individuals in the event that a password is compromised.
If a password is disclosed in a phishing attack or has otherwise been obtained or guessed, a second authentication method is required before the account can be accessed.
Two-factor authentication uses a combination of two different methods of authentication, commonly something a person owns (device/bank card), something a person knows knows (a password or PIN), and/or something a person has (fingerprint, iris scan, voice pattern, or a token).
The second factor control is triggered if an individual, authorized or otherwise, attempts to login from an unfamiliar location or from a device that has not previously been used to access the account.
For instance, a person uses their laptop to connect from a known network and enters their password. No second factor is required. The same person uses the same device and password from an unfamiliar location and a second factor must be supplied. If the login credentials are used from an unfamiliar device, by a hacker for instance that has obtained a username and password in a phishing attack, the second factor is also required.
A token or code is often used to verify identity, which is sent to a mobile phone. In such cases, in addition to a password, an attacker would also need to have the user’s phone.
Does 2-Factor Authentication Stop Phishing Attacks?
So, does 2-factor authentication stop phishing attacks from succeeding? In many cases, it does, but 2-factor authentication is not infallible. While it was once thought to be highly effective at stopping unauthorized account access, opinion is now changing. It is certainly an important additional, low-cost layer of security that is worthwhile implementing, but 2-factor authentication alone will not prevent all phishing attacks from succeeding.
There are various methods that can be used to bypass 2-factor authentication, for instance, if a user is directed to a phishing page and enters their credentials, the hacker can then use those details in real-time to login to the legitimate site. A 2FA code is sent to the user’s device, the user then enters that code into the phishing page. The attacker then uses the code on the legitimate site.
This 2-factor authentication bypass is somewhat cumbersome, but this week a phishing tool has been released that automates this process. The penetration testing tool was created by a Polish researcher named Piotr Duszynski, and it allows 2FA to be bypassed with ease.
The tool, named Modlishka, is a reverse proxy that has been modified for handling login page traffic. The tool sits between the user and the target website on a phishing domain. When the user connects to the phishing page hosting this tool, the tool serves content from the legitimate site – Gmail for instance – but all traffic passes through the tool and is recorded, including the 2FA code.
The user supplies their credentials, a 2-factor code is sent to their phone, and that code is entered, giving the attacker account access.
It is an automated version of the above bypass that only requires a hacker to have a domain to use, a valid TLS certificate for the domain, and a copy of the tool. No website phishing templates need to be created as they are served from the genuine site. Since the tool has been made available on Github, the 2FA bypass could easily be used by hackers.
Additional Controls to Stop Phishing Attacks
To protect against phishing, a variety of methods must be used. First, an advanced spam filter is required to prevent phishing emails from reaching inboxes. SpamTitan, for instance, blocks more than 99.9% of spam and phishing emails.
Fewer than 0.1% of emails may make it past the spam filter, but any one could result in an account compromise. Security awareness training should therefore be provided to employees to help them identify suspicious emails.
Unfortunately, people do make mistakes and phishing emails can be highly realistic, so it is wise to also implement a web filter.
A web filter will block attempts to connect to known phishing sites and can assess sites in real time to help determine their authenticity. If the checks fail, the user will be prevented from accessing the site.
These anti-phishing controls are now essential cybersecurity measures for businesses to protect against phishing attacks, and are all the more important since 2FA cannot be relied upon to protect against unauthorized access once a password has been compromised.
You can find out more about SpamTitan and WebTitan by contacting TitanHQ.
The last weekend of 2018 has seen a major newspaper cyberattack in the United States that has disrupted production of several newspapers produced by Tribune Publishing.
The attacks were malware-related and affected the Saturday editions of the Los Angeles Times, the San Diego Union-Tribune, the Chicago Tribune, the New York Times, the Wall Street Journal, and others. The malware attack occurred on Thursday, December 27, and caused major problems throughout Friday.
All of the affected newspapers shared the same production platform, which was disrupted by the malware infection. While the type of malware used in the attack has not been publicly confirmed, several insiders at the Tribune have reported that the attack involved Ryuk ransomware.
Ransomware is a form of malware that encrypts critical files preventing them from being accessed. The primary goal of attackers is usually to obtain ransom payments in exchange for the keys to decrypt the encrypted files. It is also common for ransomware to be deployed after network access has been gained and sensitive information has been stolen, either to mask a data breach or in an attempt to make an attack even more profitable. It is also not unknown for ransomware attacks to be conducted to cause disruption. It is suspected that this newspaper cyberattack was conducted primarily to disable infrastructure.
The type of ransomware used in an attack is usually easy to identify. After encrypting files, ransomware changes file extensions to an (often) unique extension. In the case of Ryuk ransomware, extensions are changed to .ryk.
The Los Angeles Times has attributed it to threat actors based outside the United States, although it is unclear which group was behind the cyberattacks. If the attack was conducted to disable infrastructure it is probable that this was a nation-state sponsored attack.
The first Ryuk ransomware cyberattacks occurred in August. Three U.S. companies were attacked, and the attackers were paid at least $640,000 for the keys to unlock the data. An analysis of the ransomware revealed it shared code with Hermes malware, which had previously been linked to the Lazarus Group – An APT group with links to North Korea.
While many ransomware campaigns used mass spamming tactics to distribute the ransomware and infect as many end users as possible, the Ryuk ransomware attacks were much more targeted and involved considerable reconnaissance and extensive network mapping before the ransomware is finally deployed. As is the case with SamSam ransomware attacks, the campaign is conducted manually.
Several methods are used to gain access to networks, although earlier this year a warning about Ryuk ransomware was issued by the U.S. Department of Health and Human Services claiming email to be one of the main attack vectors, highlighting the importance of email security and end user training to help employees recognize email-based threats.
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.

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 firstname.lastname@example.org.
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.

A major San Diego School District phishing attack has been discovered. The phishing attack stands out from the many similar phishing attacks on schools due to the extent of accounts that were compromised, the amount of data that was potentially obtained, and the length of time it took for the data breach to be detected.
According to a recent breach announcement, the login credentials of around 50 district employees were obtained by the attacker. It is not unusual for multiple accounts to be breached in school phishing attacks. Once access is gained to one account, it can be used to send internal phishing emails to other staff members. Since those emails come from within, they are more likely to be trusted and less likely to be detected. Investigations into similar phishing attacks often reveal many more email accounts have been compromised than was initially thought, although 50 sets of compromised credentials is particularly high.
Those accounts were compromised over a period of 11 months. The San Diego School District phishing attack was first detected in October 2018 after staff alerted the district’s IT department to phishing emails that had been received. Multiple reports tipped off the IT department that an ongoing cyberattack was occurring and there may have been a data breach.
The investigation revealed the credentials obtained by the attacker provided access to the district’s network services, which included access to the district’s database of staff and student records. The school district is the second largest in California and serves over 121,000 students each year. The database contained records going back to the 2008/2009 school year. In total, the records of more than 500,000 individuals were potentially obtained by the hacker. Given the length of time that the hacker had access to the network, data theft is highly probable.
The data potentially obtained was considerable. Student information compromised included names, addresses, dates of birth, telephone numbers, email addresses, enrollment and attendance information, discipline incident information, health data, legal notices on file, state student ID numbers, emergency contact information, and Social Security numbers. Compromised staff information also included salary information, health benefits data, paychecks and pay advices, tax data, and details of bank accounts used for direct deposits.
Data could be accessed from January 2018 to November 2018. While it is typical for unauthorized access to be immediately blocked upon discovery of a breach, in this case the investigation into the breach was conducted prior to shutting down access. This allowed the identity of the suspected hacker to be determined without tipping off the hacker that the breach had been detected. The investigation into the breach is ongoing, although access has now been blocked and affected individuals have been notified. Additional cybersecurity controls have now been implemented to block future attacks.
School district phishing attacks are commonplace. School districts often lack the resources of large businesses to devote to cybersecurity. Consequently, cyberattacks on school districts are much easier to pull off. Schools also store large volumes of sensitive data of staff and students, which can be used for a wide range of malicious purposes. The relative ease of attacks and a potential big payday for hackers and phishers make schools an attractive target.
The San Diego School District phishing attack is just one of many such attacks that have been reported this year. During tax season at the start of 2018, many school districts were targeted by phishers seeking the W-2 forms of employees. It is a similar story every year, although the threat actors behind these W-2 phishing attacks have been more active in the past two years.
In December this year, Cape Cod Community College suffered a different type of phishing attack. The aim of that attack was to convince staff to make fraudulent wire transfers. At least $800,000 was transferred to the attackers’ accounts in that attack.
These attacks clearly demonstrate the seriousness of the threat of phishing attacks on school districts and highlights the importance of implementing robust cybersecurity protections to protect against phishing.

campaign is to obtain users’ Office 365 passwords.
The phishing campaign was detected by ISC Handler Xavier Mertens and the campaign appears to still be active.
The phishing emails closely resemble legitimate Office 365 non-delivery notifications and include Office 365 branding. As is the case with official non-delivery notifications, the user is alerted that messages have not been delivered and told that action is required.
The Office 365 phishing emails claim that “Microsoft found Several Undelivered Messages” and attributes the non-delivery to “Server Congestion.” The emails ask the sender to retype the recipient’s email address and send the message again, although conveniently they include a Send Again button.
If users click the Send Again button, they will be directed to a website that closely resembles the official Office 365 website and includes a login box that has been auto-populated with the user’s email address.
While the Office 365 phishing emails and the website look legitimate, there are signs that all is not what it seems. The emails are well written and the sender’s email – email@example.com – looks official but there is irregular capitalization of the warning message: Something that would not occur on an official Microsoft notification.
The clearest sign that this is a phishing scam is the domain to which users are directed if they click on the Send Again button. It is not an official Microsoft domain (agilones.com).
While the error in the email may be overlooked, users should notice the domain, although some users may proceed and enter passwords as the login box is identical to the login on the official Microsoft site.
The campaign shows just how important it is to carefully check every message before taking any action and to always check the domain before disclosing any sensitive information.
Scammers use Office 365 phishing emails because so many businesses have signed up to use Office 365. Mass email campaigns therefore have a high probability of reaching an Outlook inbox. That said, it is easy to target office 365 users. A business that is using Office 365 broadcasts it through their public DNS MX records.
Businesses can improve their resilience to phishing attacks through mandatory security awareness training for all employees. Employees should be told to always check messages carefully and should be taught how to identify phishing emails.
Businesses should also ensure they have an advanced spam filtering solution in place. While Microsoft does offer anti-phishing protection for Office 365 through its Advanced Threat Protection (APT) offering, businesses should consider using a third-party spam filtering solution with Office 365.
SpamTitan provides superior protection against phishing and zero-day attacks, an area where APT struggles.
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.

Adobe has issued an unscheduled update to correct flaws in Adobe Flash Player, including a zero-day vulnerability that is currently being exploited in the wild by an APT threat group on targets in Russia. One target was a Russian healthcare facility that provides medical and cosmetic surgery services to high level civil servants of the Russian Federation.
The zero-day flaw is a use-after-free vulnerability – CVE-2018-15982 – which allows arbitrary code execution and privilege execution in Flash Player. A malicious Flash object runs malicious code on a victim’s computer which gives command line access to the system.
The vulnerability was discovered by security researchers at Gigamon ATR who reported the flaw to Adobe on November 29. Researchers at Qihoo 360 identified a spear phishing campaign that is being used to deliver a malicious document and associated files that exploit the flaw. The document used in the campaign was a forged employee questionnaire.
The emails included a .rar compressed file attachment which contained a Word document, the vulnerability, and the payload. If the .rar file is unpacked and the document opened, the user is presented with a warning that the document may be harmful to the computer. If the content is enabled, a malicious command is executed which extracts and runs the payload – A Windows executable file named backup.exe that is disguised as an NVIDIA Control Panel application. Backup.exe serves as a backdoor into a system. The malicious payload collects system information which is sent back to the attackers via HTTP POST. The payload also downloads and executes shell code on the infected device.
Qihoo 360 researchers have named the campaign Operation Poison Needles due to the identified target being a healthcare clinic. While the attack appears to be politically motivated and highly targeted, now that details of the vulnerability have been released it is likely that other threat groups will use exploits for the vulnerability in more widespread attacks.
It is therefore important for businesses that have Flash Player installed on some of their devices to update to the latest version of the software as soon as possible. That said, uninstalling Flash Player, if it is not required, is a better option given the number of vulnerabilities that are discovered in the software each month.
The vulnerability is present in Flash Player 220.127.116.11 and all earlier versions. Adobe has corrected the flaw together with a DLL hijacking vulnerability in version 18.104.22.168.
A new module has been added to TrickBot malware that adds point-of-sale (POS) data collection capabilities.
TrickBot is a modular malware that is being actively developed. In early November, TrickBot was updated with a password stealing module, but the latest update has made it even more dangerous, especially for hotels, retail outlets, and restaurants: Businesses that process large volumes of card payments.
The new module was identified by security researchers at Trend Micro who note that, at present, the module is not being used to record POS data such as credit/debit card numbers. Currently, the new TrickBot malware module is only collecting data about whether an infected device is part of a network that supports POS services and the types of POS systems in use. The researchers have not yet determined how the POS information will be used, but it is highly likely that the module is being used for reconnaissance. Once targets with networks supporting POS systems have been identified, they will likely be subjected to further intrusions.
The new module, named psfin32, is similar to a previous network domain harvesting module, but has been developed specifically to identify POS-related terms from domain controllers and basic accounts. The module achieves this by using LDAP queries to Active Directory Services which search for a dnsHostName that contains strings such as ‘pos’, ‘retail’, ‘store’, ‘micros’, ‘cash’, ‘reg’, ‘aloha’, ‘lane’, ‘boh’, and ‘term.’
The timing of the update, so close to the holiday period, suggests the threat actors are planning to take advantage of the increase in holiday trade and are gathering as much information as possible before the module is used to harvest POS data.
The recent updates to TrickBot malware have been accompanied by a malicious spam email campaign (identified by Brad Duncan) which is targeting businesses in the United States. The malspam campaign uses Word documents containing malicious macros that download the TrickBot binary.
Protecting against TrickBot and other information stealing malware requires a defense-in-depth approach to cybersecurity. The main attack vector used by the threat actors behind TrickBot is spam email, so it is essential for an advanced anti-spam solution to be deployed to prevent malicious messages from being delivered to end users’ inboxes. End user training is also essential to ensure employees are made aware of the danger of opening emails from unknown senders, launching suspicious email attachments, and clicking hyperlinks in those messages.
Antivirus solutions and endpoint security controls should also be deployed to identify and quarantine potentially malicious files in case malware makes it past perimeter defenses.
There has been a steady increase in HTTPS phishing websites over the past couple of years, mirroring the transition from HTTP to HTTPS on commercial websites. HTTPS sites are those that have SSL/TLS certificates and display a green padlock next to the URL. The green padlock is an indicator of site security. It confirms to website visitors that the connection between their browser and the website is encrypted. This provides protection against man-in-the-middle attacks by ensuring data sent from the browser to the website cannot be intercepted and viewed by third parties.
HTTPS websites are now used by a large number of businesses, especially e-commerce website owners. This has become increasingly important since search engines such as Google Chrome provide clear indications to Internet users that sites may not be secure if the connection is not encrypted.
This is all good of course, but there is one caveat. Users have been told to look for the green padlock to make sure a site is secure, but the green padlock is viewed by many Internet users as a sign that the site is secure and legitimate. While the former is true, the latter is not. The green padlock does not mean that the site is genuine and just because it is displayed next to the URL it does not mean the site is safe.
If the website is controlled by a cybercriminal, all the green padlock means is that other cybercriminals will not be able to intercept data. Any information entered on the website will be divulged to the criminal operating that site.
It stands to reason for HTTPS phishing websites to be used. If Internet users are aware that HTTPS means insecure, they will be less likely to enter sensitive information if the green padlock is not present. Unfortunately, free SSL certificates can easily be obtained to turn HTTP sites into HTTPS phishing websites.
According to PhishLabs, back in Q1, 2016, fewer than 5% of phishing websites used HTTPS. By Q3, 2016, the percentage started to rise sharply. By Q1, 2017, the percentage had almost reached 10%, and by Q3, 2017, a quarter of phishing websites were using HTTPS. The 30% milestone was passed around Q1, 2018, and at the end of Q3, 2018, 49% of all phishing sites were using HTTPS.
A PhishLabs survey conducted late last year clearly highlighted the lack of understanding of the meaning of the green padlock. 63% of consumers surveyed viewed the green padlock as meaning the website was legitimate, and 72% saw the website as being safe. Only 18% of respondents correctly identified the green padlock as only meaning communications with the website were encrypted.
It is important for all Internet users to understand that HTTPS phishing websites not only exist, but before long the majority of phishing websites will be on HTTPS and displaying the green padlock. A conversation about the true meaning of HTTPS is long overdue and it is certainly something that should be covered in security awareness training sessions.
It is also now important for businesses to deploy a web filtering solution that is capable of SSL inspection – The decryption, scanning, and re-encryption of HTTPS traffic to ensure that access to these malicious websites is blocked. In addition to reading content and assessing websites to determine whether they are malicious, SSL inspection ensures site content can be categorized correctly. This ensures that sites that violate a company’s acceptable usage policies are blocked.
There is a downside to using SSL inspection, and that is the strain placed on CPUs and a reduction in Internet speeds. SSL inspection is therefore optional with many advanced web filters. To ensure that the strain is reduced, IT teams should use whitelisting to prevent commonly used websites from being subjected to SSL filtering.

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

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

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.
