  • Possible DCSync from a non domain controller Low 5 variations

    Attacker's goals: An attacker is trying to retrieve Active Directory data, including password hashes.
    Investigative actions: Check whether one of the machines is a new domain controller.

  • Potential DCSync by an unusual user Informational Identity Analytics 1 variation

    Attackers may leverage the domain replication process to extract sensitive information (DCSync).

    Required data: Windows Event Collector XDR Agent with eXtended Threat Hunting (XTH)
    Attacker's goals: An attacker is trying to retrieve Active Directory data, including password hashes.
    Investigative actions: Check the role of the account, and see if it should initiate a DC synchronization. Check if the account performing the DCSync is related to a new DC. Find the source host of the DCSync (correlate between event 4662 and 4624 based on the field 'Logon ID'). Check if the account was recently added to an administrative groups/had new sensitive privileges assigned to it. Monitor suspicious traffic to/from the host to identify lateral movement or access to sensitive resources.
