What it detects

This rule detects command line usage of the mimikatz sekurlsa module which the intrusion set used to extract plaintext credentials and hashes from LSASS memory during the attacks on Japanese targets. The sekurlsa keyword in a command line is a high confidence indicator of credential theft tooling even when the binary has been renamed.
