Languages Mismatch

Detection approach

Languages locale mismatch detected (navigator.languages[0] !== navigator.language). Stealth plugins that spoof preferred languages often fail to override both properties consistently.

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

Multilingual users who travel or change their system keyboard/input languages while keeping localized browsers.
