Researchers Prove That A Hard Drive’s LED Light Can Be Used To Covertly Leak Data

The seemingly harmless blinking lights on servers and desktop PCs may give away secrets if a hacker can hijack them with malware. Researchers in Israel have come up with an innovative hack that turns a computer’s LED light into a signaling system that shows passwords and other sensitive data. The researchers found that with malware, they could control the LED light to emit binary signals by flashing on and off. That flickering could send out a maximum of 4,000 bits per second or enough to leak out passwords, encryption keys and files, according to their paper. It’s likely no one would notice anything wrong. http://www.pcworld.com/
