4. Biometric & Behavioral Interactions
Flat Gyroscope Profile
Detection approach
The user agent claims this is an iPhone interacting with your site. However, the device's gyroscope and accelerometer registered absolute zero micro-movements during a 10-second session. Real humans hold their phones, resulting in natural jitter. This phone is sitting completely flat on a massive charging rack in a click farm.
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
Mobile users placing their phones completely flat on a desk, charger, or stand.
