zencleaner

MAL-2026-17629

Malicious code in zencleaner (PyPI)

Details

When a license key is activated or deactivated in the local UI, zencleaner/webhook_logger.py posts the key, the PC name, the Windows user name and the client IP to a hardcoded Discord webhook, although the README says nothing is sent to the internet. 1.0.3 and 1.0.3.1 also look up the public IP through ipify.org and ifconfig.me. Separately, cleaner_system.py clears the Windows event logs, Security included, with wevtutil; a comment in that function reads "so forensic scanners report 0 entries". Nothing runs at install time. I read all three versions and did not run them.

Compromised versions (3)

  • 1.0.0
  • 1.0.3
  • 1.0.3.1

Any computer that installed or ran a compromised version should be considered fully compromised. Rotate every secret on that machine from a clean environment.
