A forged Kerberos TGT created using the KRBTGT account hash — granting an attacker arbitrary domain access until the KRBTGT password is rotated twice.
The endgame of an Active Directory compromise. Detection focuses on TGT lifetimes longer than the policy maximum, and on TGTs for non-existent accounts. Mitigation: scheduled KRBTGT password rotations (twice, six hours apart) plus tier 0 segregation.
See our web application penetration testing, API security testing, network penetration testing, and cloud security audit services for how we test for and defend against this class of issue.
