What it detects

This rule detects a user or admin consent grant to an OAuth service principal, a technique used in the illicit consent grant attacks documented by Huntress. Adversaries lure victims into consenting to attacker-controlled applications to obtain long-lived access tokens for mail and directory data. Because legitimate app consent is common, this detection is best paired with anomalous application naming or reply URLs and treated as a hunting lead.
