I remember reading about how secure rooms couldn't have telephones in them because there was an old school hack where you could use the copper cables at the exchange to pick up the sound from the telephone handset microphone even though it was sitting in the receiver......old school meet new school.
This is insane on so many levels, so basically if you put your cell phone near your laptop and then "open" your files while someone is performing an open mic listen......they can reverse engineering your passcode by listening to the sounds your cpu makes while processing the code.
Basically its "listening" to the electronic signals as it passes through the circuits.
Are we truly in a time where anything and everything is open and does this change how we "do things". Is it "all out there" and we just need to know how to "listen to the ether Mal".
