Talk:Van Eck phreaking

[edit] cleanup
Can someone please add the date when van Eck published his paper? Also the description of the process, particularly the section about CRTs, reads very spottily. Could it perhaps be made a bit more straightforward? I'd love to make these changes myself, but I lack the technical familiarity to do so confidently. --user: Trinite
[edit] LCDs
"Van Eck phreaking is the process of eavesdropping on the contents of a CRT or LCD display by detecting its electromagnetic emissions."
The way the article describes the process is that some CRT components not present in an LCD (the electron beam and associated components) are required to eavesdrop. The external sources listed at the bottom don't describe LCD or TFT monitors either. Did someone just assume it would work for these and add them to that line, or is this actually possible? And are there sources to confirm or negate this?

- TEMPEST treats the subject in a more comprehensive fashion, and explains that flat panel monitors are susceptible as well, by the same procedure — picking up stray electromagnetic emissions) — but from different sources of radiation. The actual display hardware seems unaffected, and consequently flat panel monitors should be easier to secure. JRM · Talk 12:26, 7 July 2006 (UTC)

- Thanks for the info, I've added a few links to the main article ('see also' section)!

- It looks like TEMPEST says "With modern flat-panel displays, the high-speed digital serial interface (DVI) cables from the graphics controller are a main source of compromising emanations." It doesn't say what else can anything beyond DVI cables. I think this is missleading. LCD monitors are resistant to Van Eck phreaking and should be listed as so. Anyone disagree? If so please educate me.

- I take back some of what I said, but this article grossly underestimates the complexity of this concept. The results of this method are extremely different between LCD and CRT monitors. Overall, this article is woefully inaccurate.

[edit] telephones
"Phreaking is the process of tapping into phone lines, used here because of its connection to eavesdropping."
This is false. Phreaking encompasses much more than just "tapping into phone lines." I'm sure the entire phreaking culture would be pretty upset at their activity being summed up as just eavesdropping. I have changed this line to "Phreaking is the process of exploiting telephone networks..."

This is linked at the bottom of the page saying it was Van Eck phreaking, but watching the video it doesn't seem like that's the case, or at least it's not obvious that it is. Can anyone confirm that the video is of Van Eck phreaking, or am I missing something? Cdills 22:02, 9 December 2006 (UTC)
- I can confirm that this is not Van Eck phreaking; the video just shows the detection of the changed refresh frequency of a LCD display (the frequency dropped for special characters like the è in Christen Democratisch Appèl), not reconstruction of the display. I've taken out the link. Oliphaunt 22:46, 17 January 2007 (UTC)
