Provenance

Reported as

PlagueSuspender suspends threads responsible for process scanning, allowing debuggers to attach without crashing the protected application

Mechanism

PlagueSuspender identifies and suspends threads that perform process scans, preventing detection of attached debuggers or analysis tools. This defeats Byfron's process protection by disabling its monitoring threads.

Detection & mitigation

Monitor for suspicious thread suspension targeting security-critical processes using ETW or kernel callbacks; deploy anti-tampering that verifies thread integrity and use protected process light (PPL) to harden security services.
