Another commenter mentioned here, they also do it on the iOS app and I don't see how Lockdown mode would change anything, it doesn't prevent to play audio.

It was pretty good until about six months ago. Since then loads of sites have added a js requirement to try to stop the AI bots.

Comment on: AliExpress runs silent WebAudio fingerprinting that breaks Bluetooth multipoint

The web around the late 90s and early 2000s had some really sketchy stuff. I think the difference is that it used to be the sleazy underbelly. Now it's accepted as mainstream.My local 'newspaper' website is chock full of scam adverts. The print version is dignified. The website people, somehow, turn a blind eye.And I got an advert on Youtube this week using sexually explicit language to sell pills.

Comment on: AliExpress runs silent WebAudio fingerprinting that breaks Bluetooth multipoint

IMO web browser have been enabling all sorts of obnoxious behavior since before JS. One of my all time favorites were the sites that opened pop-ups in a loop faster than you could close them while an audio clip of a guy yelling "Hey everyone! I'm looking at gay porn!" You had to hit reset. Fuck the Web.

I thought the App Store review guidelines explicitly prohibit hidden features and using public APIs outside their intended purpose. Is audio-based fingerprinting just not something review can realistically catch?

Comment on: AliExpress runs silent WebAudio fingerprinting that breaks Bluetooth multipoint

Ah, so that's what Wolt (Doordash but in Europe) is doing.I noticed that Voice Over (iOS screen reader) crackles and randomly changes volume when using the app, but I attributed it to standard iOS weirdness, and possibly misuse of some iOS API. Now I'm thinking that this may very well be fingerprinting.

Comment on: AliExpress runs silent WebAudio fingerprinting that breaks Bluetooth multipoint

A part of me is always smiling a little inside when people find creative ways to abuse browsers. It's always one more demonstration that the current web is fundamentally broken by design. The distinction between web browsers and random programs that allow remore arbitrary code execution is becoming more and more academic with every new feature that gets exposed to JavaScript.Of course, I am also a horrible hypocrite and will actually use websites that use features like WebUSB or WebRTC.

It's the website.The title of the article literally mentions "WebAudio", and the first paragraph states that the author is using a PC. The second paragraph mentions Chrome and Firefox.Apple and the App Store have zero involvement here.
