Playwright Bindings

Detection approach

Playwright binding artifacts detected in the global window context. Native functions were found containing __installed properties, a direct signature of Microsoft Playwright's ExposeFunction API.

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. Direct signature of Microsoft Playwright's ExposeFunction API, absent on human consumer devices.
