Has any real ones been found and confirmed?
I remember one being mentioned a couple of years ago or so by one researcher but last I can remember it was not confirmed and IIRC other researchers were voicing their doubt about it.

Reading PGP keys with a microphone up to few meters away from the laptop, from the sound of the power supply. It's more noise when it's busy. https://m.tau.ac.il/~tromer/acoustic/ https://m.tau.ac.il/~tromer/acoustic/
- eitland 7y agoThanks. Yes, this looks more familiar. For some reason my head was shortcutting "attack" to mean "infect". Thorrez in sibling comment mentions BadBIOS which is probably the one I thought about.
- Thorrez 7y agoThe one you remember was BadBIOS, and yes it was bunk.
- eitland 7y agoThanks! (Also, I realize that my brain thinks 2013 is "a couple of years ago". On a personal level that is possibly even more scary :-/ )
