WARMCOOKIE Malware Evolves with Advanced Evasion Tactics

The WARMCOOKIE backdoor malware is undergoing active development, introducing significant new capabilities despite law enforcement disruptions. Recent variants feature enhanced execution handlers and a sophisticated "string bank" evasion technique that uses legitimate company names to disguise its presence on infected systems. The malware's infrastructure remains resilient, reusing expired SSL certificates and shifting towards domain-based command-and-control servers. Analysis of campaign IDs and encryption keys suggests a complex operational structure, possibly a malware-as-a-service model with customized builds for different operators. These continuous updates indicate WARMCOOKIE will remain a persistent and evolving threat, requiring adaptive defense strategies.

Cyber Espionage Campaign Targets Diplomats with PlugX Malware

A threat actor known as UNC6384 has been targeting European diplomatic entities in a cyber-espionage campaign since September. The group exploits a high-severity Windows vulnerability and uses refined social engineering tactics to deliver PlugX malware. The campaign, which initially targeted entities in specific regions, is expanding across the broader diplomatic community. The attack chain involves spear-phishing emails leading to malicious LNK files that exploit the vulnerability and execute obfuscated PowerShell commands. Researchers recommend organizations review and block command-and-control infrastructures and conduct security awareness training to mitigate such attacks.
