News: Computer spy methods found in LED lights
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.

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.
