Detection approach
Silent Audio Render Trap detected active audio fingerprint alteration. A 0Hz silent oscillator rendered non-zero noise, proving an active audio-randomizer extension is spoofing the browser profile. Alternatively, getChannelData and copyFromChannel buffers desynchronized, a typical fingerprint of incomplete AudioBuffer prototype wrapping.
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
Employees browsing on Citrix, VMware, or virtual audio routing configurations.
