#890 On her microphone's secret service: How spies, anyone can grab crypto keys from the air
In a paper published by the Association for Computing Machinery, researchers from Tel Aviv University have detailed how inexpensive kit can be used to harvest 4,096-bit encryption keys in just a few seconds and from distances of around 10 metres (33 feet).

These are the same boffins who hid a loop of wire and a USB radio dongle in a piece of pita bread last year and used it to steal keys over the air.

In their latest research, the team managed to pick up encryption keys using acoustics. As a computer's processor churns through the encryption calculations, the machine emits a high-frequency "coil whine" from the changing electrical current flowing through its components.
