As a result, the KDC will issue the ticket using the privileges of DC1$.Ĭombining CVEs CVE-2021-42278 and CVE-2021-42287, an attacker with domain user credentials can leverage them for granting access as a domain admin.Īccess Token Manipulation (T1134), Exploitation for Privilege Escalation (T1068), Steal or Forge Kerberos Tickets (T1558) Therefore, the KDC will perform another lookup appending a trailing $. When processing the TGS request, the KDC will fail its lookup for the requestor machine DC1 the attacker created. If a TGS was requested for an account that couldn't be found, the KDC will attempt to search it again with a trailing $. When performing an authentication using Kerberos, Ticket-Granting-Ticket (TGT) and the Ticket-Granting-Service (TGS) are requested from the Key Distribution Center (KDC). This escalation attack allows attackers to easily elevate their privilege to that of a Domain Admin once they compromise a regular user in the domain.

In this article, you'll learn how to understand, classify, remediate and prevent the following types of attacks: The following security alerts help you identify and remediate Compromised credential phase suspicious activities detected by Defender for Identity in your network. For information about True positive (TP), Benign true positive (B-TP), and False positive (FP), see security alert classifications. To learn more about how to understand the structure, and common components of all Defender for Identity security alerts, see Understanding security alerts. Microsoft Defender for Identity identifies these advanced threats at the source throughout the entire attack kill chain and classifies them into the following phases: Typically, cyber-attacks are launched against any accessible entity, such as a low-privileged user, and then quickly move laterally until the attacker gains access to valuable assets – such as sensitive accounts, domain administrators, and highly sensitive data.
