What it detects

This rule flags Windows process creation events where the command line contains Mimikatz-related tool strings such as "mimikatz" or "DumpCreds". It also matches common Mimikatz module invocations and keywords (e.g., module/function markers like "::" and actions such as "sekurlsa::", "lsadump::", "token::", "dpapi::"). This matters because credential-dumping tools often leave distinctive command-line artifacts that defenders can spot in process telemetry. The detection relies on command line fields captured at process start.
