What it detects

This rule detects wevtutil clearing the Security, Application, or System event logs, an anti-forensic action performed by The Gentlemen ransomware operators to erase traces of intrusion. Wiping logs hampers incident response and hides prior activity. Detection of log clearing is a strong indicator of hands-on-keyboard compromise.
