And there are hacks to make other components work as antennas, so there it is again, the dependency on a clean firmware. But the range without a dedicated radio chip is considerably less, reducing the risk in theory for many users.
Yes, that too. You can use Rpis pin to transmit FM radio for instance. Which gives me crazy idea: if you transmitted a fake ad "call <number> and say <seed> to win 1M dollars" how many people could hear it and would call?
I mean the power available to do that from inside a hardware wallet is probably not gonna make it far enough for much anyone to do much with it, doubly so if you only have a relatively limited time to get it through before you run out of power.
Yep, this specific idea was just funny thought, not a serious attack.
