# Playbook for T1003 - Credential Dumping - Mimikatz DCSync

This playbook provides systematic remediation steps to investigate incidents suspected to be caused by Mimikatz DCSync. This playbook triggers when one of the Mimikatz functions `(lsadump::dcsync`\) is used. The function is typically used on attacked Domain Controllers \(DC\).

Mimikatz is a popular hacking tool that enables users to issue commands that help retrieve confidential data from the attacked system. The confidential data includes passwords, their hashes, and others.

**Note:** This is a high-fidelity alert, which is assumed to be rarely triggered. When it triggers, you should notify a senior team member or Manager immediately.
