Electromagnetic Scanners Can Detect What You’re TypingRight Now

It ’s obvious to assume that your henpecking on a wireless keyboard could be tap by a RF - snooping ne’er - do - well , but what about your wired or laptop keyboard — that should be safe , right ? Nope . Researchers at Lausanne , Switzerland ’s Security and Cryptography Laboratory ( part of the EPFL school ) havedemonstratedhere that 12 unlike keyboards , buy from 2001 until now , can be eavesdropped upon by monitor their electromagnetic signature — wirelessly , from up to 65 human foot away , through walls .

. This 2nd video demonstrates the second hardening of their experimentation . The researchers devise four separate methods for EM eavesdropping , which will be detail in specific in a newspaper to be turn after match revue . The method for intercept sign regard discover the full spectrum of electromagnetic radiotherapy emitted by a keyboard ( which are unshielded to keep cost and spring factors down ) , and analyzing the specific change in signal over a variety of wavelength for each key pressure . All the more reason to work / live in a giant Farraday cage . LASEC / EPFL ]
