[Noisebridge-discuss] hack a computer by the sound of the CPU

[Johny Radio]

"...possible to distinguish most of the programs which the computer was 
running, and in some of them it was possible to distinguish between the 
acoustic signature of different RSA secret keys (signing or decryption), 
and fully extract decryption keys, by measuring the sound the machine 
makes during decryption of chosen ciphertexts.

...All you need is a mobile phone placed at 20-30 cm from the computer 
you want to hack."
