Detection approach
Chrome notification permission inconsistency detected. The Notification API reports 'denied', but the permissions.query API reports 'prompt'. This is a known fingerprint of Headless Chrome.
How this helps detect bots
Collect this signal alongside session context, request metadata, and other independent indicators. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.
Legitimate traffic to consider
Brave Browser users or users running custom privacy configurations that block permission querying.
