New Malware Threats Uncovered This Week

Cybersecurity Week in Review: Emerging Threats and Critical Vulnerabilities

This week’s roundup brings a mix of intriguing cybersecurity developments – from LLM package hallucinations impacting supply chains to critical fixes in Nagios Log Server – alongside some gripping vulnerabilities and malware updates making headlines. It’s been a busy week with plenty to digest, so let’s break down the key stories.

LLM Package Hallucinations and Real-World Impact

One of the more unexpected issues making waves is the impact of language model (LLM) package hallucinations on supply chains. While these “hallucinations” don’t belong to the realm of surreal art, they can inadvertently introduce errors that compromise the entire supply chain process. Because even the best AI can occasionally see things that aren’t there, businesses need to be cautious and proactive in mitigating these risks.

Malware Updates: MysterySnail RAT on the Prowl

Cybersecurity experts have uncovered an updated, more advanced version of the MysterySnail remote access trojan (RAT) malware. Believed to be operated by the Chinese-speaking IronHusky hacker group, this version aims to infiltrate sensitive government networks. The sophistication of this malware update highlights the ongoing battleground between cyber attackers and organisations striving to secure their systems.

Critical Vulnerabilities in Networking Devices

A series of critical vulnerabilities affecting Tenda W12 and i24 devices have come to light this week. Multiple CVEs have been disclosed, each with a high severity rating, and they serve as a timely reminder of the importance of patching and vulnerability management. Here’s a quick glance at the issues:

• CVE-2025-3820: A stack-based buffer overflow in the function cgiSysUplinkCheckSet within /bin/httpd can trigger a remote attack. (Severity: 8.8)
• CVE-2025-3803: Another buffer overflow vulnerability in the function cgiSysScheduleRebootSet exposes these devices to remote exploitation. (Severity: 8.8)
• CVE-2025-3802: The function cgiPingSet in the same file is similarly at risk, potentially allowing remote attackers to manipulate the device. (Severity: 8.8)
• CVE-2025-43917: In a different vein, this vulnerability affects the Pritunl Client. An administrator with access to /Applications can escalate privileges after uninstalling the product, essentially leaving a backdoor open for unauthorised commands. (Severity: 8.2)

These vulnerabilities are particularly concerning as they are already disclosed to the public, meaning attackers have the blueprints for exploitation. It’s a stark reminder for network administrators to regularly update firmware and review system integrity.

Strengthening Vulnerability Tracking: CISA and MITRE’s Extended Partnership

Amid these vulnerabilities, there’s some reassuring news on the organisational front. CISA has extended MITRE’s contract to operate the CVE programme for an additional 11 months. Alongside this, the establishment of a new non-profit CVE Foundation is set to bolster the long-term sustainability and global governance of vulnerability tracking. The continued partnership ensures that security experts worldwide can keep a closer eye on emerging threats with reliable updates.

Staying Ahead in the Cybersecurity Landscape

Whether it’s headline-grabbing malware or vulnerabilities in widely used devices, keeping pace with these developments is crucial for businesses of all sizes. For organisations in the UK – including those in Yorkshire – staying compliant and secure is imperative. At Synergos Consultancy, we’re committed to helping companies navigate these challenges, guiding them through ISO Certifications, GDPR compliance, and other critical standards in a continually evolving cybersecurity environment.

In a world where digital threats continue to evolve, every update brings not just a warning, but also a chance to improve our defences. Here’s to another week of vigilance and continuous improvement in the cybersecurity sphere!
