hi all,

last night i was sceptical about the possibility of deriving an actual password based on the remotely observed frequency of a CPU (various methods could be used to observe the frequency)

did a google check this morning, found this one using the acoustic levels of the CPU fan back in 2013


and looks like the same researchers upgraded their technique to electro magnetic in 2015
