Golden Ticket

Adversaries who have the KRBTGT account password hash may forge Kerberos ticket-granting tickets (TGT), also known as a golden ticket. Golden tickets enable adversaries to generate authentication material for any account in Active Directory. Using a golden ticket, adversaries are then able to request ticket granting service (TGS) tickets, which enable access to specific resources. Golden tickets require adversaries to interact with the Key Distribution Center (KDC) in order to obtain TGS. The KDC service runs all on domain controllers that are part of an Active Directory domain. KRBTGT is the Kerberos Key Distribution Center (KDC) service account and is responsible for encrypting and signing all Kerberos tickets. The KRBTGT password hash may be obtained using OS Credential Dumping and privileged access to a domain controller.

Open detection, hunting, mitigation, and evidence workspace

Detection logic

Monitor for anomalous Kerberos activity, such as malformed or blank fields in Windows logon/logoff events (Event ID 4624, 4672, 4634), RC4 encryption within TGTs, and TGS requests without preceding TGT requests. Monitor the lifetime of TGT tickets for values that differ from the default domain duration. Monitor for indications of Pass the Ticket being used to move laterally.

M1026 · Privileged Account Management

Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures: Account Permissions and Roles: - Implement RBAC and least privilege principles to allocate permissions securely. - Use tools like Active Directory Group Policies to enforce access restrictions. Credential Security: - Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials. - Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO). Multi-Factor Authentication (MF…

M1015 · Active Directory Configuration

Implement robust Active Directory (AD) configurations using group policies to secure user accounts, control access, and minimize the attack surface. AD configurations enable centralized control over account settings, logon policies, and permissions, reducing the risk of unauthorized access and lateral movement within the network. This mitigation can be implemented through the following measures: Account Configuration: - Implementation: Use domain accounts instead of local accounts to leverage AD’s centralized management, including group policies, auditing, and access control. - Use Case: For IT staff managing shared resources, provision domain accounts that allow IT teams to log in centrally, reducing the risk of unmanaged, rogue local accounts on individual machines. Interactive Logon Restrictions: - Implementation: Configure group policies to restrict interactive logons (e.g., direct…

MITRE detection strategies and analytics

DET0144 · Detect Forged Kerberos Golden Tickets (T1558.001)
  • AN0405 · Analytic 0405 — Detects forged Kerberos Golden Tickets by correlating anomalous Kerberos ticket lifetimes, unexpected encryption types (e.g., RC4 in modern domains), malformed fields in logon/logoff events, and TGS requests without preceding TGT requests. Also monitors for abnormal patterns of access associated with elevated privileges across multiple systems.
