Threats Tagged 'gpu mining'

Microsoft Defender Experts identified an active cryptojacking campaign leveraging AI-assisted delivery mechanisms alongside traditional SEO poisoning. Attackers create fake download sites impersonating trusted utilities like CrystalDiskInfo, HWMonitor, and FurMark, targeting users with high-performance GPUs. Victims download ZIP archives containing legitimate executables bundled with malicious DLLs that establish persistence via ScreenConnect remote access tools. The operation employs sophisticated techniques including DLL sideloading, process hollowing into Microsoft-signed .NET binaries, and comprehensive defense evasion. Beyond cryptocurrency mining, the campaign establishes persistent remote access that could enable data theft, lateral movement, or ransomware deployment. The threat actors deliberately target PC enthusiasts and hardware-focused users most likely to own discrete GPUs suitable for profitable mining operations.

A series of attacks targeting Korean Internet cafés have been identified, focusing on systems with specific management software installed. The threat actor, active since 2022, uses Gh0st RAT for system control and ultimately installs T-Rex CoinMiner for cryptocurrency mining. The initial access method remains unknown. The attacks involve memory patching of management software and use of downloaders. The malware suite includes Gh0st RAT, its droppers, patchers, downloaders, and T-Rex CoinMiner. Unlike typical coin mining operations using XMRig for Monero, this actor employs T-Rex, likely due to the presence of high-performance GPUs in Internet café PCs. The attacks have been ongoing since late 2024, prompting responses from management software manufacturers.
