How to leak sensitive data from an isolated computer (air-gap) to a near by mobile phone - AirHopper

...a breakthrough method (AirHopper) for leaking data from an isolated computer to a mobile phone without the presence of a network...The main idea behind the research is to use radio frequencies in order to transmit the secret data from the computer to the mobile phone. Mobile phones usually come equipped with FM radio receivers and it is already known that software can intentionally create radio emissions from a video display unit. 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.

Amazing, though perhaps some practical difficulties....

One assumes that the mobile phone has specially-written software on it, in order to pick up the FM transmission, so it (the phone) would be in the possession of the password-stealer.

The VDU would presumably be of the CRT design.
