What it detects

This rule flags events where an end user consents to an application with admin consent marked as false. Adversaries may abuse user-level consent flows to gain application access without requiring tenant-wide approval. Detection relies on Azure audit log fields indicating the consent context, specifically the IsAdminConsent value.
