Laptops And Flat Panels Now Vulnerable to Van Eck Methods 144

An anonymous reader writes "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.'"
