Just a gripe:

Why do you always link to your own posts when referring to old projects? It’s just an extra click to see the actual project and it’s really annoying.

I have posted some links to research publications relating to tempest in this topic (should be the 1st post). Can anyone tell me how come my post did not appear?

One creepy thing I heard the NSA can reconstruct an image from a unshielded monitor though they need to be very close.
On side note the RFI emissions were how they used to get altairs to play music back in the 70s.

I think now they use a special copper mesh to block signals and encrypt all out side communications.

Well, if they’re going to listen, might as well share a few tunes with’em. :)

Having guards secure a 100ft perimeter around the device would not be effective with the use of directional antennas, unless I’m missing something here.

Tempest is actually a technical standard by which electronics are secured against radiological intelligence gathering methods aka RINT. In specific the methodology employed here is van eck listening. It annoys me that people call it tempest anything when tempest is the security standard itself and utterly unrelated to the science or the application of it in these situations. There is a great doc from USENIX a couple years back about how to pick up emissions off of digital cables running to LCDs and why it’s actually easier to do on an lcd than on a crt. Fun app though. Always loved eliza… the only problem is … for some reason programmers and specifically hackers all name their apps eliza. It’s wierd.

“Their new, heavily shielded and line filtered version of the device was rejected by the military who simply told commanders to monitor a 100 feet around their post to prevent eavesdropping” :D thats a simple and effective solution ;)
