Detect DCSync attacks (MITRE T1003.006) where adversaries abuse Active Directory replication privileges to extract password hashes, by auditing Event ID 4662 for the DS-Replication-Get-Changes GUIDs and flagging non-domain-controller accounts issuing DsGetNCChanges RPC calls. Use when hunting for credential theft via Mimikatz lsadump::dcsync or Impacket secretsdump, investigating lateral movement with domain admin credentials, or auditing AD replication permissions.

# Detecting DCSync Attack in Active Directory
## When to Use
- When hunting for credential theft in Active Directory environments
- After compromise of accounts with Replicating Directory Changes permissions

- During incident response involving lateral movement with domain admin credentials
- When auditing AD replication permissions as part of security hardening
## Prerequisites
- Windows Security Event Logs with Event ID 4662 (Object Access) enabled
- Advanced Audit Policy: Audit Directory Service Access enabled
