MicroWorld Technologies, the maker of eScan antivirus, experienced a supply-chain compromise where malicious updates were pushed through the legitimate eScan updater. This multi-stage malware establishes persistence on infected systems, enables remote access for attackers, and blocks automatic security mechanisms. Although no known exploits are currently observed in the wild, the threat poses a medium severity risk due to its potential impact on confidentiality, integrity, and availability. European organizations using eScan antivirus are at risk, especially those in countries with higher adoption of this product. The attack leverages trusted update channels, making detection and prevention more challenging. Mitigation requires immediate verification of update integrity, network monitoring for unusual remote access, and enhanced endpoint detection capabilities. Countries with significant use of eScan and strategic sectors reliant on this antivirus are more likely to be targeted. The threat underscores the critical risk of supply-chain attacks in cybersecurity defenses.

A Microsoft Teams voice-phishing campaign leveraging Quick Assist, a remote administration tool, was tracked in September 2025. The campaign uses help desk scams to gain initial access, followed by user group enumeration and the execution of a PowerShell script to download a command and control payload. The attack employs AMSI bypass, encrypted communications, and a web-socket remote access trojan. Multiple Microsoft 365 tenants with IT-related subdomains were used, along with various IPs and domains for C2 infrastructure. The campaign shows similarities to Storm-1811 and PhantomCaptcha activities, suggesting a complex cybercrime ecosystem. The attackers' ultimate goal may be ransomware deployment, although observed attempts were successfully blocked.
KRVTZ-NET IDS alerts from February 2, 2026, report reconnaissance and early exploitation attempts targeting Fortigate VPN devices via CVE-2023-27997. The activity includes repeated GET requests to the /remote/logincheck endpoint, inbound requests to hidden environment files, and HTTP User-Agent scanning from known scanners like Censys. No active exploits are confirmed in the wild and no patches are currently available. The threat mainly affects organizations using Fortigate VPN appliances, with European countries such as Germany, France, the UK, Netherlands, Italy, Spain, Belgium, and Sweden at elevated risk. The threat is assessed as high severity due to potential impact and ease of exploitation despite low immediate risk. Mitigation involves enhanced network monitoring, access restrictions, IDS/IPS deployment, and proactive vulnerability management.

Threat actors associated with ShinyHunters-branded extortion operations are expanding their tactics, targeting cloud-based SaaS applications for data theft and extortion. The attackers use sophisticated voice phishing and credential harvesting to gain initial access, then exfiltrate sensitive data from various platforms. They employ aggressive extortion tactics, including harassment and DDoS attacks. The activity involves multiple threat clusters (UNC6661, UNC6671, UNC6240) and targets a growing number of cloud platforms. The attackers leverage social engineering to bypass MFA and use tools like ToogleBox Recall to cover their tracks. This activity highlights the effectiveness of social engineering and the importance of phishing-resistant MFA methods.

A sophisticated multi-stage malware campaign employs living-off-the-land techniques and in-memory payload delivery to evade security controls. The infection chain begins with a hidden batch file that executes an embedded PowerShell loader, which then injects Donut-generated shellcode into legitimate Windows processes. The final payload is a heavily obfuscated .NET framework implementing advanced anti-analysis techniques, credential harvesting, surveillance capabilities, and remote system control. Data exfiltration occurs via Discord webhooks and Telegram bots. The malware, identified as Pulsar RAT, features live chat functionality and background payload deployment, demonstrating a modern, high-evasion Windows malware operation designed for long-term access and large-scale data theft.
