🎧 AliExpress reportedly used browser audio processes, tied to Alibaba's systems, to create a unique device "fingerprint" for tracking users without cookies, potentially interfering with Bluetooth devices.
💻 Researchers discovered code on AliExpress that utilized the Web Audio API to run silent audio processes, even at zero volume, to measure subtle device-specific audio hardware variations.
📊 Beyond audio, these scripts also gathered data from canvas rendering, WebGL, display settings, hardware, WebRTC, and user interactions to create detailed device profiles, used by platforms for fraud prevention and risk assessment.
🛡️ Brave browser flagged this behavior, stating it blocks these AliExpress scripts and has had built-in protections against audio fingerprinting for over six years, also extending similar measures to GPU fingerprinting.
