What it detects

This rule flags events where an application is granted a delegated permission grant for all users with highly privileged scope. Such grants can enable broad access under the app’s identity, increasing the impact of credential theft or malicious OAuth consent. It relies on Azure audit log entries with the message indicating a delegated permission grant.
