What it detects

This rule detects execution of Mimikatz through its characteristic privilege debug and logonpasswords module arguments as seen in the ScreenConnect to Hive ransomware case where the actor dumped cleartext credentials from LSASS and this matters because these command sequences are unique to credential theft tooling and precede rapid domain wide compromise.
