Overview
Unknown threat actors compromised CPUID (cpuid[.]com), a website that hosts popular hardware monitoring tools such as CPU‑Z, HWMonitor, HWMonitor Pro, and PerfMonitor. For less than 24 hours, the site served malicious executables masquerading as these legitimate utilities and deployed a remote‑access trojan (RAT) known as STX RAT.
The incident spanned roughly from April 9, 15:00 UTC to April 10, 10:00 UTC.
