Security researchers demonstrate AirHopper, leak data from isolated networks

[Ink]

Think your completely isolated, internet-disconnected "air gap" computer network is secure from wireless infiltration? Think again -- security researchers at Ben-Gurion University in Israel have found a way to lift data from closed networks using little more than a standard computer monitor and FM radio waves. It's a pretty clever trick: researchers have created a keylogging app called AirHopper that can transmit radio frequencies by exploiting the PC's display. A companion app on an FM-equipped smartphone can decode those transmissions and record the host machine's keystrokes in real-time.

Yes, from the computer screen. Still, this is the first time that a mobile phone is considered in an attack model as the intended receiver of maliciously crafted radio signals emitted from the screen of the isolated computer. AirHopper demonstrates how textual and binary data can be exfiltrated from physically a isolated computer to mobile phones at a distance of 1-7 meters, with effective bandwidth of 13-60 Bps (Bytes per second). Enough to steal a secret password.
