What it detects

This rule detects a delegated permission grant that targets an Entra agent blueprint access_agent scope, the consent step that lets an attacker-controlled app drive an assistive AI agent. Adversaries obtain delegated access to agents that can send mail and act on the user behalf, so a grant referencing access_agent indicates agent hijacking through illicit consent.
