Detects when domain federation settings are configured or modified in an Entra ID tenant via the Microsoft Graph API. Adversaries with Global Administrator or Domain Administrator privileges may add a custom domain, verify ownership, and configure it to federate authentication with an attacker-controlled identity provider. Once federated, the adversary can forge SAML or WS-Federation tokens to authenticate as any user under that domain, bypassing MFA and conditional access policies. This technique, commonly known as Golden SAML, was used by UNC2452 (APT29) during the SolarWinds campaign for persistent, stealthy access to victim tenants.
