Every graphics card renders specific images and WebGL elements slightly differently based on hardware drivers. Sannysoft extracts the WebGL vendor and renderer strings. If these strings explicitly mention terms like "SwiftShader" or "Mesa" (which indicate software-based virtual machine rendering), anti-bot systems know the browser is running inside a headless server environment.
