Native Patching

Detection approach

Native function patching detected on core APIs (e.g., navigator.permissions or document.createElement). A script is actively trying to hide its spoofed environment.

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

Users with security extensions (e.g. NoScript, Privacy Badger) or enterprise monitoring tools that wrap native APIs.
