Fast Facts A covert malware-as-a-service group, TAG-150, has been distributing custom remote access Trojans (RATs), primarily targeting U.S. government agencies and critical infrastructure, with over 1,600 known attacks. The operation remains largely hidden, with no significant presence on the Dark Web, suggesting it may be exclusive and operated by more sophisticated cybercriminals, complicating detection and law enforcement efforts. TAG-150 has developed two distinct RAT variants—an invasive C-based version with broad features and a stealthy Python-based "PyNightshade"—aimed at maximizing operational flexibility and evading antivirus detection. The group’s evolving malware toolkit indicates intentions to scale operations, potentially expanding its reach and sophistication,…

Quick Takeaways The GPUGate campaign manipulates Google Ads and GitHub to trick users into downloading malware, exploiting trust in both platforms to deliver malicious payloads. It employs a novel GPU-gated decryption technique, only decrypting its payload if a physical GPU is detected, making analysis difficult in sandbox environments. The malware targets IT professionals and developers in Western Europe, aiming for organizational access to steal credentials, exfiltrate data, or deploy ransomware. Once inside, it elevates privileges via PowerShell, establishes persistence, and evades detection by modifying Windows Defender, representing an advanced and ongoing threat since late 2024. Problem Explained The “GPUGate” malware…
