Browser Tampering
Detect when browser APIs have been overridden
What it detects
Identifies when JavaScript APIs have been tampered with or overridden. Tampering is a common technique used by bots, anti-detect browsers, and fingerprint-spoofing extensions.
How it works
Tests browser APIs for signs of modification: prototype chain alterations, toString() output inconsistencies, property descriptor mismatches, and timing anomalies that indicate function wrapping.
