I’m sure Temu collects all information you put into the app and your behaviour in it, but this guy is making some very bold claims about things that just aren’t possible unless Temu is packing some serious 0-days.

For example he says the app is collecting your fingerprint data. How would that even happen? Apps don’t have access to fingerprint data, because the operating system just reports to the app “a valid fingerprint was scanned” or “an unknown fingerprint was scanned”, and the actual fingerprint never goes anywhere. Is Temu doing an undetected root/jailbreak, then installing custom drivers for the fingerprint sensor to change how it works?

And this is just one claim. It’s just full of bullshit. To do everything listed there it would have to do multiple major exploits that are on state-actor level and wouldn’t be wasted on such trivial purpose. Because now that’s it’s “revealed”, Google and Apple would patch them immediately.

But there is nothing to patch, because most of the claims here are just bullshit, with no technical proof whatsoever.

Wouldn’t the phone have to have your fingerprint stored in order to compare it to the one scanned?

Yes, the phone does, but that data is protected in the hardware and never sent to the software, the hardware basically just sends ok / not ok. It’s not impossible to hack in theory, nothing is, but it would be a very major security exploit in itself that would deserve a bunch of articles on it’s own.

Pretty sure this is not true. That’s how apple’s fingerprint scanners work. On android the fingerprint data is stored either in the tpm or a part of the storage encrypted by it.

Yeah, so the app never sees it. What are you disagreeing with?

I just corrected that, can’t I without disagreeing?

I mean that I don’t know what part of my comment is “not true”. I welcome corrections, I just don’t see what is being corrected here.
