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 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 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.

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 OAuth application consent grants where the application requests both 'offline_access' (enabling refresh tokens for long-term access) and sensitive mailbox permission scopes (such as Mail.Read, Mail.ReadWrite, Mail.Send, or IMAP.AccessAsUser.All). This combination is indicative of consent phishing attacks designed to establish persistent, silent access to user email accounts, bypassing password resets and multi-factor authentication.
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).
This rule detects the granting of sensitive, high-privilege Microsoft Graph API delegated or application permissions to an application or service principal in an Entra ID environment. Such permissions, including directory and user management or full application access, are frequently used by adversaries for persistence and privilege escalation within cloud environments.

Detects anomalous sign-in activity for service principals (non-interactive accounts) where the same application authenticates from multiple distinct countries within a 24-hour window. This behavior often indicates the unauthorized use of compromised service principal credentials, such as client secrets or certificates, from distributed attacker-controlled infrastructure.

Detects a potential Business Email Compromise (BEC) persistence chain where a user grants an OAuth application mailbox read/write permissions, followed immediately by the creation of an inbox rule (forwarding, moving, or deleting) targeting messages containing keywords like 'invoice', 'wire', or 'payment'.
