Detects OAuth2 permission consent events where a user grants a third-party or newly registered application access to high-risk scopes (such as Mail, Files, or Directory). This technique is commonly used to establish persistence and bypass MFA by gaining access to user accounts via malicious or compromised OAuth applications.
Detects mass-phishing consent campaigns by monitoring non-admin users consenting to multi-tenant or unverified-publisher applications requesting non-basic-profile OAuth scopes. The rule aggregates multiple consent events for the same application over a 1-hour window to identify potentially malicious consent-phishing activity.
Detects modifications to Microsoft Entra ID (formerly Azure AD) cross-tenant access settings. This rule alerts on changes that allow external tenants to interact with the environment, such as enabling inbound/outbound trusts, automatic redemption, or trusting MFA claims, which can be leveraged to establish persistence or facilitate lateral movement between tenants.

Detects modifications to Microsoft Entra ID (formerly Azure AD) Conditional Access policies that lower security posture. This includes disabling policies, switching them to report-only mode, removing Multi-Factor Authentication (MFA) or grant control requirements, or expanding exclusion lists to exempt users, groups, or locations from security controls. Such modifications are often indicative of an adversary attempting to maintain persistent access or bypass MFA requirements.
Detects a potential Primary Refresh Token (PRT) or device code phishing attack by identifying a two-step authentication sequence: first, a successful user sign-in via device code flow, followed shortly by a subsequent sign-in from a different, unmanaged, or untrusted device. This behavioral pattern often indicates an adversary using stolen device code session data to authenticate a new device session.
Detects modifications to federated domain authentication, identity provider trusts, or federation settings in cloud environments (e.g., Entra ID, Okta). Unauthorized changes to these configurations can be used to establish persistence, enable SAML token forgery, or bypass Multi-Factor Authentication (MFA).
Detects the assignment of highly privileged Azure AD/Entra ID directory roles (e.g., Global Administrator, Application Administrator) to a service principal. Assigning such roles to service principals is a common persistence technique, as these identities can be used to bypass conditional access policies and MFA through non-interactive authentication methods like client credentials.
