What it detects

This rule detects Entra ID audit events where consent is granted to an application. During the Midnight Blizzard intrusion analyzed by Wiz Research the actor consented malicious OAuth applications to high-privilege Graph permissions such as full_access_as_app, so unexpected consent grants can indicate an attacker establishing persistent mailbox and directory access.
