The applications, used by individuals and enterprises, have millions of downloads. According to the maintainer of CPUID, a secondary feature (side API) was compromised, causing the website to randomly display links to third-party domains hosting trojanized versions of CPU-Z, HWMonitor, and PerfMonitor.
