AliExpress discovered to be covertly listening to users via browser scripts
Developer Matthew Callaghan noticed that music on his phone stopped when AliExpress website opened on his PC. His Bluetooth headphones supported multipoint, allowing simultaneous connection to his phone and computer. Blocking AliExpress tab or muting web browser didn't fix the issue. Callaghan discovered AliExpress was using hidden scripts, collina.js and fireyejs.js, to listen to users.
These scripts generated unseen audio signals, analyzed how browsers processed them, and collected various device and behavioral data. The scripts formed part of Alibaba's security infrastructure, likely for fraud prevention. However, the fingerprinting occurred on the general AliExpress homepage before sensitive actions. Blocking the scripts stopped the audio issue but may cause additional CAPTCHAs or interfere with login and payment checks.
