What it detects

This rule detects Mimikatz command modules such as sekurlsa logonPasswords and lsadump sam being passed on the command line, the credential-access step in the ELPACO-team Confluence intrusion where logon passwords and SAM secrets were harvested to a results log. Adversaries run these Mimikatz modules to extract plaintext and hashed credentials from memory and the registry, so these module strings are a high-confidence dumping indicator regardless of the binary name.
