A team of researchers from British universities has trained a deep learning model that can steal data from keyboard keystrokes recorded using a microphone with an accuracy of 95%.
Given that there’s variance among even the same key switches, as well as differences in sound based on the construction of the keyboard the switches are placed in, possibly even based on the surface the keyboard is placed on, the model would probably have to be trained specifically for a given target.
Since I’m working from home, I have much bigger things to worry about if attackers get access to my physical machine to train their model lol
