What it detects

This rule detects use of rundll32 to invoke the MiniDump export of comsvcs.dll against the LSASS process, the credential-access technique documented in CERT-FR analysis of the APT28 intrusion set targeting French entities. Adversaries leverage this signed LOLBin to capture a memory dump containing plaintext and hashed credentials, making early detection critical for stopping privilege escalation and lateral movement.
