Detection approach
Empty keyboard layout map on desktop environment. Headless setups or virtualized servers (like Linux/Docker runners) report size 0, whereas physical desktop systems expose mapped layouts.
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
Users with high security blocks or using custom OS partitions with disabled layout queries.
