Remember the blinking light on the CD tray on your old PC? Early ones would leak data that way, the light could be decoded. While I was searching for that, I found a more recent attack where the light is repurposed to actually just transmit data. And I found another proof of concept that uses the RAM cycles to transmit data through the air.
Its a good thing I don't have any secrets.
Keep in mind that this argument can get abused. Your privacy is always secret. Just because you have nothing to hide doesn't mean you shouldn't be keeping it hidden.
Um ... ya, thanks for that insightful advice. If you didn't catch it, I've been around since CD lights were leaking data. And I know all about it. I aint new.

Sorry. I was irritated w sombody else. Peace.
Van Eck Phreaking, figuring out what a computer is doing from nothing more than it's stray radio emissions, is some magical shit.
I read a good chunk of the paper. It was surreal.
