Researchers at Fox‑IT have managed to wirelessly extract secret AES-256 encryption keys from a distance of one metre (3.3 feet) – using €200 (~US$224) worth of parts obtained from a standard electronics store – just by measuring electromagnetic radiation. At that distance sniffing the keys over the air took five minutes, but if an attacker got within 30 centimetres (11.8 inches) of a device, the extraction time is cut down to just 50 seconds.

There are, of course, some caveats. The tests took place under laboratory conditions, rather than in a busy office or server room where other signals might interfere with the data collection. But it's an interesting example of how an attack previously thought of as unfeasible due to cost and distance has been made easier by smarter and cheaper technology.
