I have never done it, but I have seen the results, it shows legible text.
Ross Anderson at Cambridge University has produced a set of word processing
software that can defeat V-E scanning using software only. What you see on
the screen is not what you see in the van - it's unintelligible. I don't
know how it works and I have no idea if anyone is picking up on it

Subject: [PEN-TEST] Penetration Testing and Van Eck Scanning

Just a thought I had while on a nicotine-and-caffeine break:

Has anyone ever done a bit of Van Eck (aka TEMPEST)
surveillance as part of
a penetration test, just to show people what can be seen from
a van in the
corporate parking lot when the security attendant is on his
lunch break?
That could provide a few hot debates in boardrooms,
especially if one were
to tune in to the Internet browsing habits of a few senior

Has anyone done it, or had/seen it done (esp. outside of a military
environment)? Are there any good references around re.
proposed civilian
standards for 'safety' from Van Eck scanning? And where would one look
around either for people who do that type of surveillance, or
the equipment
to do that with.

And, finally, if this is not the right forum for such
discussions, could
anyone in the know point me to such?

Very ta,
