The latest Security Affairs Malware newsletter covers several significant malware threats that have emerged recently. Notably, a group identified as Stan Ghouls is targeting users in Russia and Uzbekistan using the NetSupport Remote Access Trojan (RAT), which allows attackers to control infected systems remotely. Another concerning development is the discovery of ZeroDayRAT, a new spyware designed to infiltrate both Android and iOS devices. Additionally, researchers have uncovered a Linux botnet named SSHStalker, which utilizes old-school IRC methods to compromise new victims. These activities demonstrate the evolving tactics of cybercriminals and emphasize the need for users and organizations to remain vigilant against these persistent threats.

Last week, a newly patched vulnerability in BeyondTrust's Remote Code Execution (RCE) software was exploited in the wild. This vulnerability poses significant risks as it allows attackers to execute commands on affected systems without authorization. BeyondTrust has issued patches to address this issue, but organizations using the affected software need to act quickly to apply these updates to prevent potential breaches. Additionally, in an interview, Deneen DeFiore, the Chief Information Security Officer at United Airlines, discussed the importance of resilience in cybersecurity. She emphasized that while prevention is crucial, organizations must also prepare for disruptions and manage risks associated with their interconnected vendor and partner ecosystems. This dual focus on resilience and safety is essential for maintaining operational integrity in today's complex digital landscape.

A recent investigation by Q Continuum has uncovered that 287 Chrome extensions are leaking private browsing data from approximately 37.4 million users to companies like Similarweb and Alibaba. These extensions, often perceived as harmless tools, have been found to convert users' browsing histories into marketable products. The data breach raises significant privacy concerns, particularly for users who may not be aware that their online activities are being monitored and sold. This incident highlights the need for users to be vigilant about the extensions they install and the permissions they grant. As these extensions may not seem malicious at first glance, it serves as a reminder of the potential risks associated with browser add-ons.

Recent threat intelligence reports indicate that a single threat actor is behind the majority of attacks exploiting two critical vulnerabilities in Ivanti Endpoint Manager Mobile (EPMM), identified as CVE-2026-21962 and CVE-2026-24061. These vulnerabilities allow for remote code execution, posing significant risks to organizations using this mobile management solution. The findings suggest that companies using Ivanti's software need to be vigilant, as the attacks are actively occurring. The focus on a single actor highlights the need for targeted defenses against this specific threat. Organizations are encouraged to monitor for unusual activity and apply any available patches to mitigate potential exploitation.

Attackers are targeting users of cryptocurrency hardware wallets Trezor and Ledger by sending fake physical letters that appear to be from these companies. These letters aim to deceive users into revealing their recovery phrases, which can be used to steal their cryptocurrencies. This tactic exploits the trust users have in these well-known wallet providers and could lead to significant financial losses for those who fall for the scam. It’s crucial for users to be cautious and verify any communications they receive, especially when it comes to sensitive information like recovery phrases. The rise of such scams underscores the need for increased awareness and education around cryptocurrency security.

A newly identified hacking group, suspected to be linked to Russian intelligence, has launched attacks against various Ukrainian sectors, including defense, government, and energy. This group is using a malware called CANFAIL, which was uncovered by researchers from Google Threat Intelligence Group. The targeting of critical infrastructure and military entities raises significant concerns about national security and the ongoing conflict in the region. As these attacks could disrupt essential services and information systems, the situation highlights the need for enhanced cybersecurity measures among the affected organizations. This incident is part of a broader pattern of cyber warfare tactics being employed against Ukraine.

North Korean hackers are running a fake recruiter scheme aimed at JavaScript and Python developers, using enticing cryptocurrency-related coding challenges to lure victims. These challenges often contain hidden malware designed to compromise the developers' systems. This tactic exploits the growing interest in cryptocurrency and the remote job market, making it especially appealing to tech professionals looking for work. Developers who engage with these fake opportunities risk not only their personal data but also their work environments, as the malware can lead to further security breaches. Awareness of these scams is crucial for developers to protect themselves from potential attacks.

Conpet, Romania's national oil pipeline operator, has confirmed that its data was compromised due to a Qilin ransomware attack that targeted its IT infrastructure last week. This incident raises concerns about the security of critical infrastructure, as ransomware attacks can disrupt essential services and lead to significant operational challenges. While specific details about the type of data compromised haven't been disclosed, the breach highlights the ongoing risks that organizations in crucial sectors face from sophisticated cybercriminals. The attack underscores the need for robust security measures in protecting vital systems against ransomware threats. Stakeholders in the energy sector should take note and review their security protocols to prevent similar incidents.
