    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.
