The infection only affects users who downloaded the app on April 9 and 10. 2026. Norton should pick up this trojan with a full system scan.

AI Overview

The official CPUID website was compromised between April 9–10, 2026, serving trojanized, malware-infected installers for CPU-Z and HWMonitor. The breach delivered a Remote Access Trojan (RAT) designed to steal browser credentials. The website is now fixed, but users who downloaded these tools during that window should run full security scans immediately.

What Happened

  • Source: The official CPUID.com website was breached, not the application code itself.
  • Scope: Reports indicate the compromise affected HWMonitor 1.63 and certain CPU-Z downloads around April 9th/10th, 2026.
  • Malware Type: The infected installer delivered a “Stuxnet-style” RAT and stealer, with some users reporting Russian-language prompts during installation.

Action Required If You Downloaded Recently

  1. Scan Immediately: Run a full scan with a reputable antivirus, such as Malwarebytes.
  2. Change Credentials: Assume all stored browser passwords, session cookies, and login details were compromised. Change critical passwords immediately.
  3. Check for Suspicious Files: Look for unusual .exe files or unexpected network activity.
  4. Reinstall Software: Download a new copy now that the site has been cleared.
  5. Reinstall Windows (If Needed): If malware is confirmed, reformatting the PC is the only way to be 100% sure it is gone.

The breach was a “watering hole” attack similar to a recent campaign targeting FileZilla. As of April 10th, 2026, CPUID has confirmed the malicious files were removed.
