Just saw the air gap show. Very nice idea. Problem is, if your main machine is owned, and they put a script on it that writes a keylogger to any attached flash, plugging in a flash drive could transfer that script over to your pristine box. Info can get back to the net box over the same flash drive, jumping the gap. I can't believe the NSA would use this technique.

Hey all. I am running Ubuntu 9.10 on a few boxes at home. Have Verizon Fios router, with wifi through the house, wpa2 with a random alphanumeric password, SSID broadcast turned off and MAC verification on. I was playing around with Ubuntu Remote Desktop, and turned it on on 1 box, allowing viewing and control of the box through Remote Desktop, thinking this was safe, as an intruder would have to get on the local network through the router firewall to hack the box. I was surprised to see that someone was able to get in and control the mouse and open some files on the box. I immediately closed down the box and inactivated Remote Desktop. Any ideas about safety/hackability?? I thought I was doing everything right and no one would have been able to easily get through wpa2. (I know the wifi doesn't extend to the curb, so was someone sitting in my backyard with a sniffer???). Any ideas are appreciated. Thanks, Maypo.
