Detects potential DCSync attacks by monitoring for Windows Event ID 4662 (Object Access) where a non-domain controller account exercises directory replication rights (DS-Replication-Get-Changes-All) against Active Directory domain objects. This identifies unauthorized attempts to pull sensitive credential data directly from a Domain Controller.
