AliExpress was silently running audio in your browser to fingerprint and track your device

AliExpress has been found to be using silent audio to fingerprint and track users' devices. The practice came to light after researchers discovered that the e-commerce platform was running audio through users' browsers without their knowledge. This method of fingerprinting allows AliExpress to gather unique information about each device, enabling more precise tracking. The revelation has sparked discussions about privacy and the ethical use of technology in online shopping. The practice was first reported by Malwarebytes, The Next Web, and The Register.

According to CyberInsider and Cybernews, the technique involves using the WebAudio API to generate and analyze audio signals, which can then be used to create a unique fingerprint for each device. This fingerprint can be used to track users across different websites and sessions, even if they clear their cookies or use private browsing modes. The Register also noted that the silent audio trick muted a developer's headphones, drawing attention to the issue. AliExpress has not yet publicly addressed the allegations. The platform's use of silent audio for fingerprinting has raised concerns among privacy advocates and users.

Researchers and cybersecurity experts have called for greater transparency and regulation in how companies collect and use user data. The incident underscores the need for stronger privacy protections and more ethical practices in the tech industry. Users and experts alike are watching for any response from AliExpress regarding the allegations. The incident serves as a reminder of the importance of vigilance in protecting personal data online. As the conversation around privacy continues to evolve, companies will need to adapt their practices to meet the growing expectations of users.
