Canvas Poisoning

Detection approach

Canvas poison detected. 2D rendering of a transparent 1x1 image returned poisoned non-zero pixel data. This proves a privacy extension or automated spoofing framework (like Brave's Farbling or CanvasBlocker) is actively poisoning canvas outputs.

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

Brave users (with "Farbling" enabled) or users with CanvasBlocker privacy extensions.
