description: This rule identifies Windows process creation command lines containing common Mimikatz identifiers and module/function markers used in credential-access activity. Attackers rely on Mimikatz-style arguments (e.g., DumpCreds or module namespaces like sekurlsa::, dpapi::, lsadump::, vault::) to enumerate credentials and access sensitive material. It uses Windows process command-line telemetry and matches partial string patterns across the full command line.

What it detects

This rule identifies Windows process creation command lines containing common Mimikatz identifiers and module/function markers used in credential-access activity. Attackers rely on Mimikatz-style arguments (e.g., DumpCreds or module namespaces like sekurlsa::, dpapi::, lsadump::, vault::) to enumerate credentials and access sensitive material. It uses Windows process command-line telemetry and matches partial string patterns across the full command line.
