The team also tested accuracy during a Zoom call, in which the keystrokes were recorded with the laptop’s microphone during a meeting. In this test, the AI was 93% accurate in reproducing the keystrokes. In Skype, the model was 91.7% accurate.
There are some ways around this kind of attack, as reported by Bleeping Computer.
the AI model was trained on the waveform, intensity, and time of each keystroke to identify them
In the wild, this attack would take the form of malware installed on your phone or another nearby device with a microphone. Then, it just needs to gather data from your keystrokes and feed them into an AI model by listening on your microphone.
