Description
ADFS DKM key attribute (thumbnailphoto) access in AD container, potential Golden SAML token forging attempt.
Attacker's Goals
The attack goal is to forge a valid SAML token to impersonate any user and gain persistent, unauthorized access to cloud resources, effectively bypassing MFA and standard security controls.
Investigative actions
- Check for recent changes to the SAML signing certificate on both the Identity Provider and the Service Provider to rule out a configuration drift or expiration issue.
- Check for other correlated alerts on on-premises systems that may be related to the Golden SAML attack.
- Look for signs that the user account is compromised (e.g. abnormal logins, unusual activity).
