From the BBC:
Computer criminals could soon be eavesdropping on what you type by analysing the electromagnetic signals produced by every key press.
By analysing the signals produced by keystrokes Swiss researchers have reproduced what a target typed.
The security researchers have developed four attacks that work on a wide variety of computer keyboards.
The results led the researchers to declare keyboards were “not safe to transmit sensitive information”.
Using a radio antenna and relatively “inexpensive equipment”, researchers demonstrated that every keyboard, whether it’s plugged into the USB or PS/2 port, or embedded into laptops, was vulnerable to at least one of four attacks they had devised. One attack could work up to 20 metres away.
