CDP Stack Trace Trap

Detection approach

CDP prepareStackTrace hook trap triggered. Error.prepareStackTrace caught serialization execution (DevTools or an automated CDP console logger inspected the environment). This is a definitive signature of Chrome DevTools Protocol automation.

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

Site-monitoring tools (Sentry, LogRocket, Datadog) or privacy extensions intercepting console logs.
