Hi list,

I've seen some fuss about the technique called "tempest" lately. Some
people claim it would be "the thing" in modern security. This bugs me
somehow because first of all I think it is way to much of an effort
compared to the more casual techniques used today. Also all information
that I can find on the Internet refers to some stuff the NSA released in
the mid-nineties. Now that is not really a good and reliable source of
information in my believe. :)

Can anybody tell me how far evolved this technique is today and who uses
it? Maybe some reference to a whitepaper or something similar. Would be
great.

Thanks
Paul

Brief definition of tempest for those who have never heard of it:
Picking up the radiation produced by a monitor or cables that connect
the graphics-card or graphics-chipset with the monitor in order to spy
the screen of the user. Kind of like getting access to a VNC server on
the box without having input yourself. The interesting part is that it
is technically undetectable.
