Cybersecurity researchers have identified a malware campaign that exploited Hugging Face's AI infrastructure to distribute Android banking trojans. The attackers used a deceptive app called TrustBastion, which tricked users into installing what appeared to be legitimate security software. Upon installation, the app redirected users to an encrypted endpoint that linked to Hugging Face repositories, allowing the malware to evade traditional security measures. The campaign generated new malware variants every 15 minutes, resulting in over 6,000 commits in about 29 days. It infected thousands of victims globally, particularly in regions with high smartphone banking usage but lower mobile security awareness. The operation is believed to be linked to an established cybercriminal group. Security experts warn that this incident highlights vulnerabilities in trusted platforms and calls for improved security measures, including behavioral analysis systems and verification of application authenticity. The incident has also sparked discussions about the need for enhanced security protocols for AI platforms.

Microsoft's February 2026 Patch Tuesday addressed 59 vulnerabilities in Windows 11, with six confirmed as actively exploited. The most critical vulnerability is CVE-2026-21510, a Windows Shell security feature bypass with a CVSS rating of 8.8, allowing attackers to evade warnings by tricking users into opening malicious files. Another significant vulnerability, CVE-2026-21513, also rated at 8.8, affects MSHTML and allows remote attackers to bypass execution prompts through malicious code in HTML or shortcut files. CVE-2026-21514 impacts Microsoft Word and enables adversaries to disable OLE mitigations, posing risks through document-based attacks. Two local privilege escalation vulnerabilities are CVE-2026-21519 in Desktop Window Manager and CVE-2026-21533 in Windows Remote Desktop Services, with CVSS scores of 7.8. CVE-2026-21525 is a denial-of-service vulnerability in Remote Access Connection Manager. The update includes 53 additional vulnerabilities across various Microsoft products and services, with CVE-2026-21531 in Azure SDK rated at 9.8 and CVE-2026-20841 affecting Windows Notepad rated at 8.8. The cumulative update for Windows 11 (KB5077181) also includes enhancements and resolves WPA3 Wi-Fi connectivity issues. Microsoft reminded users of the June 2026 expiration of Secure Boot certificates, which requires timely updates to ensure secure booting. Users can install the updates via Windows Update.

AKDAN Malware Hunters has launched the AKDAN HALL PED, a security solution that detects and neutralizes unknown document-based malware in 0.27 seconds, achieving a 99% success rate against emerging threats. This technology uses Pre-Execution Detection (PED) and a virtual "hypnosis" environment to analyze potentially malicious behavior, differing from traditional antivirus software that relies on known threat databases. CEO Sean Jeon, with over 15 years in cybersecurity, emphasizes the need for proactive measures as 91% of cyberattacks start via email, often using document-based malware. The AKDAN HALL product line includes a cloud-based agent for personal use and the AKDAN HALL Mini, a compact server for sensitive environments, both designed to complement existing antivirus solutions. The company has received support from the Initial Startup Package program at Seoul National University of Science and Technology and plans to expand into the Japanese market.

Microsoft is enhancing the security of Windows devices by replacing boot-level security certificates that are nearing expiration, with this initiative integrated into regular Windows platform updates. The original Secure Boot certificates from 2011 will expire between June and October 2026, prompting Microsoft to issue new certificates in 2023, which are included in many new Windows devices sold since 2024. Older hardware will require updates to remain compliant. Devices with expired certificates will continue to operate but will enter a "degraded security state," potentially hindering future updates and causing compatibility issues. The new Secure Boot certificates rollout began with the Windows 11 KB5074109 update. Most Windows 11 users will have the new certificates installed automatically, while specialized systems may have different update protocols. Windows 10 users must enroll in Microsoft’s Extended Security Updates to receive the new certificates.

53% of UK businesses experience cybercrime attempts at least once a month. 70% of business owners anticipate a cyber attack in the near future, but only about 35% feel prepared. 43% of cyberattacks are directed at small businesses, and over half of these may face closure due to the damage. Antivirus software can prevent data breaches, is cost-effective, reduces the likelihood of ransomware, and protects devices of remote workers.

eScan, an antivirus solution, has become a conduit for a supply chain attack that may have affected millions of users through a compromised software update mechanism. The attack exploited eScan’s automatic update system, distributing malware via official channels that appeared legitimate, thus bypassing traditional security measures. Reports indicate that supply chain attacks have increased by over 300% in the past three years, with software update mechanisms being prime targets. The exact number of affected users is still under investigation, but the breach occurred over a limited period before detection. Enterprises using eScan now face vulnerabilities in their security infrastructure, prompting IT departments to conduct forensic analyses to determine if their networks were compromised. The breach raises concerns about digital security as users typically rely on antivirus solutions for protection. Researchers found that the malware used advanced techniques, including multi-stage deployment and polymorphic behavior to evade detection, indicating significant resources behind the attack. In response, eScan has initiated an incident response protocol, revoked compromised digital certificates, and added verification layers to its update system. However, restoring user trust will require transparency about the breach and preventive measures. The incident has led to widespread security audits across the antivirus sector and may accelerate the adoption of zero-trust security models. Regulatory inquiries are underway regarding eScan's data protection practices, and legal experts anticipate class-action lawsuits from affected users and enterprises. The breach highlights a trend where attackers target security infrastructure itself, making software distribution security a critical focus for cybersecurity professionals. Proposed solutions include blockchain-based verification systems and industry-wide standards for supply chain security. The eScan breach underscores that no organization is immune to sophisticated supply chain attacks, as compromising a security vendor can provide access to its entire customer base. Increased information sharing about supply chain threats is advocated to enhance collaboration within the security industry. Moving forward, eScan must balance technical remediation with transparent communication to rebuild trust, while users are advised to implement defense-in-depth strategies rather than relying solely on one security tool.

Microsoft will disable the NTLM authentication protocol by default in the next major Windows Server release and associated Windows client versions. NTLM, introduced in 1993, has been vulnerable to various cyberattacks, including NTLM relay and pass-the-hash attacks. The transition plan includes three phases: enhanced auditing tools in Windows 11 24H2 and Windows Server 2025, new features like IAKerb and a Local Key Distribution Center in late 2026, and eventually disabling network NTLM by default in future releases. NTLM will remain in the operating system but will not be used automatically. Microsoft deprecated NTLM authentication in July 2024 and has encouraged developers to transition to Kerberos or Negotiation authentication.
