Webdriver Descriptor

Detection approach

navigator.webdriver getter descriptor missing in Chrome: stealth deleted Object.getPrototypeOf(navigator).webdriver. In real Chrome this is a native getter returning false. The deletion is the signature of puppeteer-extra-plugin-stealth's navigator.webdriver evasion.

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. Unique signature of puppeteer-extra-plugin-stealth's property deletion evasion.
