Detection approach

After a _blank link click, the original tab registered additional scroll or click events within 50 milliseconds. A human cannot interact with a background tab that fast; this proves script-driven parallel execution.

How this helps detect bots

Collect this signal alongside session context, request metadata, and other independent indicators. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

Rapid double clicking, or automated macro keys mapped by gamers or power users.
