Prototype Canary Lie

Detection approach

Prototype integrity canaries are missing from native prototypes. Non-configurable properties planted on native prototypes at script load were deleted. This proves a stealth plugin restored or replaced the prototype object to hide automation fingerprints.

How this helps detect bots

This signal is assessed with other independent session, browser, and network evidence. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

None. Stealth plugins restoring original prototypes to hide hooks wipe our verification flags.
