New cyberattack method: tracking typing remotely via keyboard sounds

A group of British cybersecurity researchers has figured out a novel new attack method: recording the sound a computer keyboard makes. The researcher took recordings using a nearby smartphone of typists and used it to train a sound classification model, achieving accuracies of 95% to suss out the actual keys pressed.

They call this an acoustic side channel attack, and it possibly could be used to steal passwords and other critical data from a target’s computer.
