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.
You should consider hiding your beer somewhere safe.
Way ahead of you. BURP.
Not mine - whenever I have to access a hard drive, I put it in the microwave (don't worry, I cut a hole in the door for the esata cable) and turn it on while the drive is reading or writing data. The background noise from the microwave obscures the relatively quiet noises made by the drive, and the magnetic field generated by the microwave's magnetron creates a magnetic bubble, or "shield" around the drive, ensuring that remote radiomagnetical analysis cannot penetrate the interior of the microwave and thus steal my important personal data (read: porn). The only problem with this setup is the drive usually stops working after a few seconds - I think this is simply due to the esata cable winding around the drive itself, so maybe if I can remove the turntable spindle from inside the microwave I can solve this minor issue.
