A team of UK researchers has trained adeep learningmodel to interpret keystrokes remotely based solely on audio.
This accuracy dropped to 93% when using Zoom to train the system.
Basically, you couldhacksensitive information armed with nothing more than a microphone and machine learning algorithm.

The team conducted the test using a MacBook Pro.
They pressed 36 individual keys 25 times a piece.
This was the basis for the machine learning model to recognise what character is associated with what keystroke sound.
