What it detects

This rule detects Azure AD/Entra directory operations that configure or modify domain federation settings, which adds or alters a trusted identity provider. UNC3944 abused hybrid identity by registering a rogue federated IdP to forge SAML tokens and impersonate any user in the tenant. Unexpected federation trust changes are a high-value indicator of a Golden SAML style backdoor.
