AliExpress runs silent WebAudio fingerprinting that breaks Bluetooth multipoint
TL;DR
AliExpress's website employs silent WebAudio fingerprinting that disrupts Bluetooth multipoint audio connections, causing audio playback issues on connected devices. This problem occurs specifically when the AliExpress page is loaded in certain browsers.
✦ Why It Matters
Test your web applications for compatibility with Bluetooth multipoint audio to avoid disrupting user experiences.
Key Takeaways
- Investigate hidden audio contexts in web pages.
- Use uBlock Origin to block specific scripts.
- Monitor Bluetooth audio behavior when browsing.
- Understand the implications of browser fingerprinting.
How It Works
The scripts create a WebAudio graph with a sawtooth oscillator and an analyser node, which processes audio data without producing audible sound. This keeps the audio path active, preventing device switching.
