I noticed in the last few weeks that if I’d recently opened the AliExpress iOS app (ie. it was backgrounded) my car audio would freak out thinking I was giving it an audio command.

I cannot ever imagine installing something like AliExpress as an app.

It's great for shopping. But in the US you have amazon prime. We don't.

Yes, I find it concerning too. I particularly dislike that windows was not aware, nor could it stop the audio stream from effecting the hardware. What other side channels like that exist? Perhaps I can be blamed for using windows

> Perhaps I can be blamed for using windows That would be unreasonable, I argue. No one should have to worry about the security of their devices and data privacy based on which OS they use. Whilst it can be argued that different OSs serve different needs, privacy and security should not be debatable. In fact, most countries have dedicated legislation for this; whether it's just, applied correctly, or serves the publi…

I am pretty sure my phone is listening. The ads I see this week are about topics I discussed last week. Week for week. Stupid thing is that I need the phone to have near by as self-employed electrician. Clients want to communicate after regular office hours. Since the phone is rigged why computer shouldn’t?

Browser fingerprinting can get creative at times, to say the least. eBay's WebSocket port scanner [1] and Reddit's abuse of DRM and JavaScript JIT exploits [2] from years ago are two examples of the kind of in-depth introspection you can perform completely in the background using nothing more than simple non-permission-gated APIs.

JS enabled by default seems every day less secure.

So many website break completely with JS disabled and you end up having to enable it half the time anyway.

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.

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 have Prime, but I can't imagine installing the Amazon app either. The website works just fine.

I don't have Amazon Prime (nor am I in the US) yet use Aliexpress perfectly fine on my mobile phone without using an app. Frankly, I don't understand how the two is related at all?
