CPU-Z / HWMonitor: Watering Hole Attack - Copy-Paste Method

    Date: 04/14/2026

    Severity: High

    Summary

    A watering hole attack compromised the official CPUID website, replacing legitimate download links for popular tools like CPU-Z and HWMonitor with malicious versions. The trojanized installers included legitimate signed executables alongside a malicious DLL (CRYPTBASE.dll) that used DLL sideloading to establish C2 communication and execute payloads after passing anti-sandbox checks. The attackers reused infrastructure and configurations from a previous campaign, highlighting a “copy-paste” approach to rapidly deploy similar supply chain-style attacks against trusted software sources.
