Laptops and Flat Panels vulnerable to Van Eck Methods (/.)

[Jason]

Just came across this on Slashdot and I must say this sounds alarming.

"Using radio to eavesdrop on CRTs has been around since the 80s, but Cambridge University researchers have now shown that laptops and flat-panel displays are vulnerable too. Using basic radio equipment and an FPGA board totaling less than $2,000 it was possible for researchers to read text from a laptop three offices away. 'Kuhn also mentioned that one laptop was vulnerable because it had metal hinges that carried the signal of the display cable. I asked if you could alter a device to make it easier to spy on. "There are a lot of innocuous modifications you can make to maximize the chance of getting a good signal," he told me. For example, adding small pieces of wire or cable to a display could make a big difference.'"
