What is DCSync and what does it do?

DCSync is a feature in mimikatz that allows an attacker to simulate a domain controller's replication behavior and request password hashes for all domain users from a legitimate domain controller using the DRS (Directory Replication Service) protocol. It is commonly used to harvest credential material for lateral movement or privilege escalation in Active Directory environments.
