Detects Active Directory object access events (Event ID 4662) associated with domain controller replication rights (Replication-Get-Changes or Replication-Get-Changes-All). This behavior is often associated with credential dumping techniques like DCSync, where an attacker impersonates a domain controller to request replication of sensitive data, such as password hashes, from another domain controller.
