How Your Smartphone Can Spy On What You Type

We all do it — place our phones down on the desk next to the keyboard. This might not be such a good idea if you want to keep your work to yourself.

A pair of neural networks were trained to recognize which keys were being pressed just based on the vibration — and it was remarkably good at it for such a small device. There have been systems that read the keys by listening but this is the first system that can hide in mobile phone malware.
