Computer spy methods found in LED lights

Did you ever get the feeling you where being watched?
Well, seems by monitoring the flashes of LED lights on electronics equipment and the indirect glow from monitors, scientists in the United States and the United Kingdom have discovered ways to remotely eavesdrop on computer data. Make me wonder if someone is looking at me through my monitor as I'm surfing the net! You have to wonder when will it ever end?


Optical signals from the little flashing LED (light-emitting diode) lights, usually red and dotting everything from modems to keyboards and routers, can be captured with a telescope and processed to reveal all the data passing through the device, Joe Loughry, a computer programmer at Lockheed Martin Space Systems in Denver, told Reuters on Wednesday.

"It requires little apparatus, can be done at a considerable distance, and is completely undetectable," he writes in his paper, "Information Leakage from Optical Emanations." "In effect, LED indicators act as little free-space optical data transmitters, like fiber optics but without the fiber."
