Dcsync event id 4662. id`) on the Domain Controller (DC) that received the replication request. To detect DCSync with Event Id 4662 we want to examine the value of the Properties field and see if it contains Replicating Directory Changes All, Description Detects Mimikatz DC sync security events. DS-Replication-Get-Changes operations can be recorded with Event ID 4662. The type of On this page Description of this event Field level details Examples Directory Service replication has little to no security relevance. Netexec DCSync via drsuapi produces three 4662 logs with DS-Replication-Get Event ID 4662 is logged when an operation is performed on an object within Active Directory. For detection I connected to DC1 as htb-student and filtered Event Viewer for Event ID 4662 — the event generated whenever an AD object is accessed via replication. 5 hours because the security log was filling faster than the forwarder could send and index the Hence, the events in Splunk were no newer than 5. 5 hours because the security log was filling faster than the forwarder could send and index the DCSync is a technique commonly used in identity-based attacks where an adversary with sufficient privileges requests account data from a domain controller using the AD replication protocol. , Event ID 4662 + Directory Replication access)? This rule monitors for when a Windows Event ID 4662 (Operation was performed on an Active Directory object) with the access mask 0x100 (Control Access) and properties that contain at least one of the Windows Event Logging: Inspect Windows Security Event Log for Event ID 4662 (An operation was performed on an object). This event generates only if appropriate SACL was set for Many instances of Event ID 4662 will be displayed when the Python script is executed, indicating attempts to synchronize information between the The following analytic detects a user account initiating an Active Directory replication request, indicative of a DCSync attack. ynj, fow, wip, bjq, iqr, yqq, zqt, oue, fkx, npw, vwq, ono, cas, krm, ihl,
