Identifies an end-user (non-admin) consent grant in Microsoft Entra ID to an application requesting delegated scopes commonly abused in illicit consent grant (OAuth phishing) attacks, such as mail, mailbox settings, contacts, files, SharePoint, OneNote, Teams chat and Exchange Web Services. Graph scopes are evaluated together with offline_access, which returns a long-lived refresh token and gives an attacker-controlled application durable, silent access to the victim's data without stealing a password or re-prompting for MFA. The alert classifies the application owner as Microsoft first-party, in-tenant or external to help prioritize review.

Detects when a user authorizes a GitHub OAuth application. Stolen OAuth grants persist after password changes until revoked and can clone or ZIP private repositories. This is not a GitHub App installation (integration_installation.create).

Detects when a Workspace user copies a document, spreadsheet, form, or script from an external Drive into their My Drive and, within minutes from the same IP, authorizes a custom web OAuth client that requests an Apps Script scope. script.container is the container sidebar or dialog. The check also matches any other script.* scope, a *.currentonly scope, or a scope containing scripts or container. Adversaries send spearphishing links with a /copy URI parameter so the victim replicates a malicious object locally. Google names that replica with a "Copy of " prefix. The copy is performed by a domain user rather than a collaborator account, and the consent is not a known Google first-party client.

Identifies an illicit consent grant request on-behalf-of a registered Entra ID application. Adversaries may create and register an application in Microsoft Entra ID for the purpose of requesting user consent to access resources. This is accomplished by tricking a user into granting consent to the application, typically via a pre-made phishing URL. This establishes an OAuth grant that allows the malicious client applocation to access resources on-behalf-of the user.

Identifies an Microsoft 365 illicit consent grant request on-behalf-of a registered Entra ID application. Adversaries may create and register an application in Microsoft Entra ID for the purpose of requesting user consent to access resources in Microsoft 365. This is accomplished by tricking a user into granting consent to the application, typically via a pre-made phishing URL. This establishes an OAuth grant that allows the malicious client applocation to access resources in Microsoft 365 on-behalf-of the user.

Identifies a failed OAuth 2.0 token grant attempt for a public client app using client credentials. This event is generated when a public client app attempts to exchange a client credentials grant for an OAuth 2.0 access token, but the request is denied due to the lack of required scopes. This could indicate compromised client credentials in which an adversary is attempting to obtain an access token for unauthorized scopes. This is a New Terms rule where the okta.actor.display_name field value has not been seen in the last 14 days regarding this event.
