🚨 A developer browsing AliExpress made a strange discovery when his Bluetooth headphones stopped switching between devices.

After digging into the code, he reportedly found hidden scripts playing inaudible sounds to create a unique fingerprint of his computer, while also collecting data like screen size, memory, mouse behavior and WebRTC signals.

The data was then sent back to Alibaba’s servers.

There’s no evidence AliExpress recorded conversations or accessed microphones, but the tracking reportedly happened without clear user consent.
