AliExpress uses hidden Web Audio API for fingerprinting, disrupting Bluetooth multipoint audio
Key points
- AliExpress pages create two hidden AudioContext objects.
- These contexts connect to the audio destination without playing sound.
- The activity disrupts Bluetooth multipoint audio functionality.
- Scripts collina.js and fireyejs.js are responsible for this behavior.
Hidden Audio Contexts Detected
Investigation into Bluetooth multipoint audio disruption by AliExpress pages revealed the creation of two hidden AudioContext objects. These contexts enter a running state and connect nodes to AudioContext.destination, despite the absence of visible audio or video elements, media playback calls, or active Media Session metadata on the page.
Impact on Bluetooth Multipoint
The hidden audio activity causes Bluetooth multipoint headphones to prioritize the PC connection, stopping audio playback from other connected devices like a phone. Closing the AliExpress tab immediately resolves the audio disruption, indicating a direct link between the website's background processes and the Bluetooth issue.
Attribution to Anti-Abuse Tooling
Stack traces from the AudioContext constructors point to two scripts: collina.js and fireyejs.js. Both scripts are located under an AWSC directory and are identified as components of Alibaba's browser security and anti-abuse tooling. This suggests the Web Audio API is being used for browser fingerprinting or similar background processes.

Reporting from
AliExpress website scripts create hidden Web Audio API contexts that interfere with Bluetooth multipoint audio connections, even when no audible media is playing. This behavior is attributed to Alibaba's anti-abuse tooling, which uses the Web Audio API for browser fingerprinting.
