The researchers combined the sound of each key with the corresponding letter for the training. They then typed a password into the laptop and had the AI calculate which word was heard based on the sound. The AI recognized the password with an accuracy of 95 percent. To make the attack realistic, the researchers tested whether this method could also be used to spy on passwords during a video meeting via Zoom or Skype. And indeed, the AI still …
