What it detects

This rule detects Mimikatz module commands on the command line regardless of the executable name, catching renamed copies of the tool. The sekurlsa and lsadump modules extract plaintext credentials, hashes and tickets from LSASS memory and the SAM. These module strings are highly specific to credential theft and rarely appear in legitimate activity.
