Detection approach
GPU/renderer mismatch: The User-Agent claims a consumer desktop operating system, but the GPU renderer returned Mesa, SwiftShader, LLVMpipe, or Google software renderers. Real consumer machines route graphics through hardware GPUs. Software renderers indicate virtual environments.
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
Office workers running virtual desktop systems lacking dedicated physical graphics hardware.
