Keyboard sniffers to steal data

Computer criminals could soon be eavesdropping on what you type by analysing the electromagnetic signals produced by every key press.
By analysing the signals produced by keystrokes, Swiss researchers have reproduced what a target typed.
The security researchers have developed four attacks that work on a wide variety of computer keyboards.
The results led the researchers to declare keyboards were "not safe to transmit sensitive information".
Better attacks
The attacks were dreamed up by doctoral students Martin Vuagnoux and Sylvain Pasini from the Security and Cryptography Laboratory at the Swiss Ecole Polytechnique Federale de Lausanne (EPFL).
The EPFL students tested 11 different keyboard models that connected to a computer via either a USB or a PS/2 socket. The attacks they developed also worked with keyboards embedded in laptops.
Every keyboard tested was vulnerable to at least one of the four attacks the researchers used. One attack was shown to work over a distance of 20 metres.
In their work the researchers used a radio antenna to "fully or partially recover keystrokes" by spotting the electromagnetic radiation emitted when keys were pressed.
In a web posting they added: "no doubt that our attacks can be significantly improved, since we used relatively unexpensive equipments [sic]."
In videos showing their early work the researchers are seen connecting keyboards to a laptop running on battery power. They avoided using a desktop computer or an LCD display to minimise the chance of picking up signals from other sources.
Details of the attacks are scant but the work is expected to be reported in a peer-reviewed journal soon.
The research builds on earlier work done by University of Cambridge computer scientist Markus Kuhn who looked at ways to use electromagnetic emanations to eavesdrop and steal useful information.

maybe someone will steal my debt
Need some stuff designed or printed? I can help with that.
Tee hee, maybe mine too!
that baby looks fuckin evil as shit
they've basically developed binoculars. Okay so thats over stating the case but its still not impressive.
luckily i've found that dislodging every key and wrapping them in tinfoil before carefully replacing them really helps. you should try it
i think everyone would start typing extra hard
Every day it seems there is a new advancement that not 10 years ago would have been literally the heights of fantasy and science fiction.
10 years ago, hey

It might be the best recap episode ever.

It reminds me of a book that one of my high school buddies had, it was a book about how to stop hackers.
And it gave you a step by step process of many things hackers do and how they do it.
So in essence it was just a book that taught you how to be a hacker.
(edit) wait not Necronomicon, the fuck book am I thinking of
damnit, I should read threads better, cryptonomicon
whoah
these were totally the exact thoughts that were going through my head when I read the OP
this is freaky (or should I say...phreaky???)
but seriously, what the heck was the point of that scene? I didn't really get it at all, other than to show that van eck phreaking works
Ia! Ia!
except that van eck phreaking was published and proved to work in 1985
