Recommended Mitigations Against Black Basta Ransomware Attacks

The Black Basta ransomware-as-a-service (RaaS) group has been aggressively targeting critical infrastructure entities in North America, Europe, and Australia, and attacks have been stepped up, with the group’s affiliates now known to have attacked at least 500 organizations worldwide. In the United States, the group has attacked 12 of the 16 government-designated critical infrastructure sectors, and attacks on healthcare providers have increased in recent months.

Black Basta is thought to be one of multiple splinter groups that were formed when the Conti ransomware group shut down operations in June 2022. The group breaches networks, moves laterally, and exfiltrates sensitive data before encrypting files. A ransom note is dropped and victims are required to make contact with the group to find out how much they need to pay to a) prevent the publication of the stolen data on the group’s leak site and b) obtain the decryption keys to recover their encrypted data.

The group uses multiple methods for initial access to victims’ networks; however, the primary method used by affiliates is spear phishing. The group has also been observed exploiting known, unpatched vulnerabilities in software and operating systems. For instance, in February 2024, the group started exploiting a vulnerability in ConnectWise (CVE-2024-1709). The group has also been observed abusing valid credentials and using Qakbot malware. Qakbot malware is commonly distributed in phishing emails.

The Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), Department of Health and Human Services (HHS), and Multi-State Information Sharing and Analysis Center (MS-ISAC) recently issued a cybersecurity alert about Black Basta in response to the increase in attacks. The alert shares indicators of compromise and the tactics, techniques, and procedures used by the group in recent attacks. All critical infrastructure organizations have been advised to implement a range of mitigations to make it harder for Black Basta ransomware affiliates to access internal networks and move laterally. The recommended mitigations will also strengthen defenses against other ransomware groups and should be considered by all businesses and organizations.

Phishing and spear phishing are common access vectors for ransomware groups and the initial access brokers many of the groups work with, including the operators of Qakbot malware. Strengthening phishing defenses should therefore be a priority. TitanHQ offers three products that help improve phishing defenses: SpamTitan Email Security, PhishTitan, and the SafeTitan security awareness training and phishing simulation platform.

SpamTitan is a comprehensive email security and spam filtering service that blocks the full range of threats including spam, phishing, malware, viruses, and other malicious emails. Independent tests have confirmed the solution has a 99.99% spam catch rate, Bayesian autolearning and heuristics defend against advanced email threats, recipient verification using SPF, DKIM, and DMARC, antivirus protection is provided using two leading anti-virus engines, and the solution incorporates sandboxing for deep analysis of suspicious files. The sandbox is capable of detecting threats from their behavior rather than email signatures and is capable of identifying and blocking zero-day malware threats. The solution is regularly rated the best spam filter for business by independent software review sites and is one of the most popular spam filters for MSPs.

PhishTitan is a powerful anti-phishing solution for businesses that use Microsoft 365 that protects against the advanced attacks that Microsoft’s EOP and Defender miss. The solution includes auto-remediation features to help businesses rapidly respond when they are targeted by cybercriminal groups, and integrates seamlessly with Microsoft 365, augmenting Microsoft’s protections to ensure that more phishing threats are identified and blocked. PhishTitan adds banner notifications to emails from external email accounts and warnings about unsafe content, rewrites URLs to show the true destination, provides time-of-click protection against malicious URLs, provides threat data and analytics to help users assess their risk profile, and subjects all emails to AI and LLM analysis, detecting phishing threats with a high degree of accuracy and blocking threats that Microsoft misses. The solution also uses real-time analysis and threat assessments to neutralize business email compromise and spear phishing attacks before they begin.

It is important to train the workforce on how to recognize and report phishing attempts. SafeTitan is a comprehensive security awareness training platform that provides training in bite-sized chunks. The training modules are no longer than 10 minutes and are easy to fit into busy workflows. By providing regular training each month, businesses can develop a security culture and significantly improve resilience to phishing and spear phishing attacks, especially when combined with phishing simulations. The phishing simulator includes templates from real-world ransomware campaigns, and they are regularly updated based on the latest threat intelligence.

As an additional protection, multi-factor authentication should be implemented on all accounts, and phishing-resistant MFA is the gold standard. Since vulnerabilities are often exploited, it is important to ensure that software, firmware, and operating systems are kept up to date with patches applied promptly. Ransomware groups such as Black Basta are quick to exploit known vulnerabilities in their attacks. Remote access software should be secured and disabled if it isn’t used, networks should be segmented to hamper lateral movement, and backups should be regularly made of all critical data, with copies stored securely offsite on air-gapped devices. Further recommended mitigations can be found in CISA’s StopRansomware Guide.

U.S. Government and Education Sectors Targeted in Multi-Malware Phishing Campaign

The U.S. government and education sectors are being targeted by cybercriminals looking to steal sensitive data. These sectors hold large volumes of sensitive data that are easily monetized, victims can be extorted, and access to compromised networks can be sold to other cybercriminal groups such as ransomware gangs. These attacks can result in significant data breaches, major financial losses, and reputational damage that is hard to repair.

The campaign uses a combination of two malware variants and vulnerability exploitation, and the attack starts with phishing emails with malicious attachments. The campaign was identified by researchers at Veriti and delivers the notorious Agent Tesla remote access trojan (RAT) and an information-stealing malware called Taskun. Agent Tesla provides attackers with remote access to networks and is often used by initial access brokers for compromising networks, with the access sold on to other cybercriminal groups. Agent Tesla can be used to download additional payloads and has comprehensive information-stealing capabilities. The malware can log keystrokes, take screenshots, and steal credentials from browsers, wireless profiles, and FTP clients.

Taskun malware is spyware that also has information-stealing capabilities. In this campaign, the malware is used to compromise systems and make it easier for Agent Tesla to be installed, establish persistence, and operate undetected for long periods. The campaign involves emails with malicious attachments, with social engineering techniques used to trick employees into running malicious code that exploits unpatched vulnerabilities in operating systems and Office applications. The campaign involves a reconnaissance phase to identify the vulnerabilities that can be exploited to maximize the chance of a highly impactful compromise. The vulnerabilities exploited in this campaign include several Microsoft Office remote code execution vulnerabilities dating from 2010 to 2018 and takes advantage of businesses with poor patch management practices, incomplete inventories of connected devices, and devices running outdated software due to issues upgrading.

Defending against email-based attacks involving multiple malware variants and vulnerability exploitation requires a multi-layered approach to security, with cybersecurity measures implemented that provide overlapping layers of protection. The first line of defense should be advanced spam filtering software to block inbound spam and phishing emails. SpamTitan from TitanHQ is an AI-driven cloud-based email filtering service that is capable of identifying and blocking spam and phishing emails and has advanced malware detection capabilities. In addition to dual antivirus engines, the SpamTitan hosted spam filter includes email sandboxing for behavioral detection of malware threats. In independent tests, SpamTitan was shown to block 99.983% of spam emails, 99.914% of phishing emails, and 99.511% of malware.

It is important to ensure that employees are made aware of the threats they are likely to encounter. Security awareness training should be provided to teach cybersecurity best practices, eradicate risky practices, and train employees to be vigilant and constantly on the lookout for signs of phishing and malware. The SafeTitan security awareness training platform makes it easy to develop and automate comprehensive training and keep employees up to date on the latest tactics used by threat actors. SafeTitan, in combination with TitanHQ’s cloud-based anti-spam service, will help to ensure that phishing and malware threats are identified and blocked.

Cybersecurity best practices should also be followed, such as implementing multi-factor authentication on accounts, ensuring patches are applied promptly, keeping software up to date, installing endpoint antivirus solutions, and network segmentation to reduce the impact of a successful attack. It is also important to ensure there is a comprehensive inventory of all devices connected to the network and conduct vulnerability scans to ensure weaknesses are detected to allow proactive steps to be taken to improve security.

More Than Half of Cyber Insurance Claims are for Email-Based Attacks

Business Email Compromise (BEC) is one of the most financially harmful cyberattacks. BEC is an attack where a cybercriminal uses social engineering techniques or phishing to gain access to an email account with a view to tricking people into disclosing sensitive and valuable data that can be sold or used in other types of attacks or scams. The goal of many BEC attacks is to trick senior executives, budget holders, or payroll staff into making fraudulent wire transfers, changing account details for upcoming payments, or altering direct deposit information to payroll payments directed to attacker-controlled accounts. When the attack results in a fraudulent wire transfer it is often referred to as Funds Transfer Fraud (FTF).

For the past several years, the biggest cause of losses to cybercrime – based on complaints filed with the Federal Bureau of Investigation’s (FBI) Internet Crime Complaint Center (IC3) – was BEC attacks. In 2022, IC3 received reports of losses of $2.7 billion from BEC attacks and $2.9 billion in losses in 2023. A recent report from the cyber insurance provider, Coalition, explored the reasons why claims were made on policies and by far the biggest cause of claims was fraud from attacks that originated in inboxes. More than half of claims were for losses that started with emails, with 28% of claims made for BEC attacks and 28% for FTF. The number of claims related to email-based attacks makes it clear that email security is an important aspect of cyber risk management. If you want to reduce cyber risk, email security is one of the best places to start and this is an area where TitanHQ can help.

TitanHQ’s anti spam software, SpamTitan, is an advanced email security solution for businesses and managed service providers that protects against the full range of email-based attacks by blocking spam, phishing, spoofing, malware, and zero-day attacks.

Cybersecurity Solutions That Adapt to Constantly Changing Phishing Threats

Phishing typically involves impersonation of a trusted individual or brand. In email phishing, the sender’s email address is often spoofed to make it appear that the messages have been sent from a legitimate domain, the emails often include the spoofed company’s logo, the color scheme used by that company, and the messages themselves are often very similar to the official emails sent by that brand.

It stands to reason that the most commonly impersonated brands are large tech companies, as more people are familiar with those companies and use their products and services. It should not come as a surprise to hear that the most impersonated brand in Q1, 2024 was Microsoft, which was impersonated in 38% of all phishing attacks, according to data from Check Point Research, up from 30% of attacks in the previous quarter. Google was the second most impersonated brand and was impersonated in 11% of phishing attacks, up from 8% in Q4, 2023.

Phishing attacks impersonating Amazon fell from 9% in Q4, 2023 to just 3% in Q1, 2024. The fall in attacks can be explained by fewer online sales after the holiday period, with phishers favoring other brands at the start of the year. There was an increase in attacks impersonating LinkedIn to target job seekers in response to an increase in job hunting in the New Year. LinkedIn rose to third place and was impersonated in 11% of attacks. Another seasonal increase was a rise in attacks impersonating Airbnb, which made it into the top 10 most impersonated brands, likely due to the increase in holiday bookings in the New Year.

Cybercriminals often change tactics and respond to seasonal changes, such as increasing attacks impersonating delivery firms and online retailers in the run-up to the holiday season, and piggyback on the popularity of major news stories and sporting events. This year is an Olympics year, and the European Football championships will be held in Germany in June. Lures related to these events are certain to be used as interest grows over the coming weeks as the events draw closer.

What is clear from phishing data is attacks are becoming more numerous and more sophisticated. According to tracking data by the Anti-Phishing Working Group (APWG), there were more than five million phishing attempts reported in 2023, the highest total ever recorded by APWG. Attacks against social media platforms showed a marked increase as the year drew to an end and accounted for almost 43% of all phishing attacks.

QR code phishing is also increasing. QR codes are used to send traffic to malicious URLs, and they are highly effective for phishing. Email security solutions typically check embedded hyperlinks against lists of known malicious domains, with many following hyperlinks and assessing the sites that users are redirected to. Many email security solutions, however, lack the capability to read QR codes, so the messages often end up in inboxes where they can be opened by end users.

It is not only email phishing that is increasing. Vishing – voice phishing attacks continue to rise and there was a major increase in Business Email Compromise (BEC) attacks, which the APWG data shows increased by 24% compared to the previous quarter.  As phishing attacks increase in number and sophistication, businesses need to ensure that their defenses are capable of blocking these threats and that their employees are trained to be on high alert and constantly look for the signs of phishing in all communications.

One of the most important protective measures for businesses is to have an effective Office 365 spam filter. The anti-spam and anti-malware protections put in place by Microsoft and included with all licenses (EOP) are effective at blocking spam and known malware, but it is not so effective at blocking zero-day phishing and malware threats, many of which land in users’ inboxes. The more advanced protection that is provided with Microsoft’s E5 premium license improves phishing detection considerably, yet even this measure does not block many sophisticated phishing attempts. As such, many businesses are keen to improve the Office 365 spam filter and look for a third-party cybersecurity solution.

An increasing number of businesses are signing up for advanced AI- and machine learning-driven protection from TitanHQ to improve protection for Microsoft 365 environments. The engine that powers two of TitanHQ’s most popular cybersecurity solutions – SpamTitan and PhishTitan-  has VBSpam+ certification from Virus Bulletin and in Q1, 2024 tests, was found to have a spam catch rate of 99.983%, a phishing catch rate of 99.914%, a malware catch rate of 99.51%, and a false positive rate of 0.00%. Overall, the engine got a 99.983% overall score.

SpamTitan is a cost-effective, easy-to-use email security solution for stopping phishing attacks, spam, malware, and ransomware. The solution features AI-based phishing protection via the newest zero-day threat intelligence, double malware protection with two antivirus engines, a next-generation sandbox for analyzing the behavior of messages to identify zero-day threats, and the solution is easy to integrate with Microsoft 365 to improve protection.

PhishTitan is a cloud-based, next-generation phishing protection and remediation solution that has been developed for use with Microsoft 365 that can identify and block the advanced phishing threats that Microsoft misses. PhishTitan has a high detection accuracy and uses AI to assess the content, tone, and meaning of emails to identify unusual, suspicious, and malicious messages. The solution also adapts to constantly evolving phishing tactics.

URLs in phishing emails are rewritten to identify their true destination, are compared to an extensive range of intelligence feeds, and the solution provides time-of-click protection against malicious links in emails. The solution also learns from user feedback to further improve accuracy and applies banners to emails warning about potentially malicious content and can be used by IT teams to automate the remediation of phishing emails from inboxes.

Phishing attacks are getting more sophisticated and tactics are constantly changing, but with the advanced protection provided by SpamTitan and PhishTitan that significantly improves the Microsoft 365 spam filter, businesses will be prepared.
