Breaching Air-Gap Security With Radio

An anonymous reader writes: Security researcher Mordechai Guri with the guidance of Prof. Yuval Elovici from the cyber security labs at Ben-Gurion University in Israel presented at MALCON 2014 a breakthrough method ("AirHopper") for leaking data from an isolated computer to a mobile phone without the presence of a network. In highly secure facilities the assumption today is that data can not leak outside of an isolated internal network. It is called air-gap security. AirHopper demonstrates how the computer display can be used for sending data from the air-gapped computer to a near by smartphone. The published paper and a demonstration video are at the link.

Most places have a faraday cage in which the classified material and any electronic device accessing the material is houses. If a device leaves the cage, it is handled appropriately and never turned on. Problem solved. Such measures have been used well before Gene Hackman's cage in Enemy of the State :-) Of course, a human mistake is much more likely to reveal the information...
