Compromising Wired Keyboards
Flavien writes "A team from the Security and Cryptography Laboratory (LASEC) in Lausanne, Switzerland, found 4 different ways to fully or partially recover keystrokes from wired keyboards at a distance up to 20 meters, even through walls. They tested 11 different wired keyboard models bought between 2001 and 2008 (PS/2, USB and laptop). They are all vulnerable to at least one of the 4 attacks. While more information on these attacks will be published soon, a short description with 2 videos is available."
Most modems back in the '80s just ran either RD, TD, or (RD|TD) through the LED. It was cheap and easy and gave you a good activity signal. Nobody cared about people sniffing the data through the LED, and really hardly anyone is ever going to be in a situation where they're even potentially exposed. And for virtually all the rest, this is hardly the low hanging fruit... if you can get close enough to read the LED, you're close enough to see what the target is doing any number of easier ways.
I don't see the big "News Flash" on this.
I think the big news flash on this is that they actually performed four different, real attacks on real, physical keyboards. Theory is one thing, someone actually saying "hey, we can really do this on the cheap now to 11 different keyboards sold at your local Best Buy; here's how..." is another. I don't think it's unreasonable to consider that "news for nerds."
