Researchers Sniff Keystrokes From Thin Air, Wires

narramissic writes "Two separate research teams have found that the electromagnetic radiation that is generated when a computer keyboard is tapped is actually pretty easy to capture and decode. Using an oscilloscope and an inexpensive wireless antenna, the Ecole Polytechnique team was able to pick up keystrokes from virtually any keyboard, including laptops — with 95 percent accuracy over a distance of up to 20 meters. Using similar techniques, Inverse Path researchers Andrea Barisani and Daniele Bianco picked out keyboard signals from keyboard ground cables. On PS/2 keyboards, 'the data cable is so close to the ground cable, the emanations from the data cable leak onto the ground cable, which acts as an antenna,' Barisani said. That ground wire passes through the PC and into the building's power wires, where the researchers can pick up the signals using a computer, an oscilloscope and about $500 worth of other equipment. Barisani and Bianco will present their findings at the CanSecWest hacking conference next week in Vancouver. The Ecole Polytechnique team has submitted their research for peer review and hopes to publish it very soon."

    Hello! So, this is my first post on Slashdot (I love the name! It's so clever. When I tried to tell somebody the address, h - t - t - p, colon, slash, slash, slashdot dot org they got soooo confused! I laughed at the sheer cleverness of the founders!)

    Anyway, I'm just glad to finally be posting here on ole Slashdot. It's a pretty neat website, and looks so modern and clean! I wish I knew how to design websites as well as this one, I'd be a hit at the next office party after I redesign our internal bbs. It'll be super :)

    So, how's everybody doing this afternoon :) I'm great! Hope to hear back from you guys soon! Until then, ~Jason.

    One of the displays contained a gigantic object that looked like it would take two men to shift.

    yes things have gotten much smaller over the years, even the shift key.

    ok this is what happening, my parents are out with family friends, and theyll be back any minute so i need your help Heres some background: see, i volunteer on my sisters softball team (im 22, the girls are 15) and whatever yea i met this girl, her name is Alison, and were going out for a while. We have a lot in common, sometimes i help her with homework. I helped her on her english essay and she still got a D. This is because the teacher is a prick ... anywayz So she came over like an hour ago, and i really want to lose my virginity, so i ask her to have sex "no, no i cant, its not right" she said, but i told her "dont worry i know what im doing, ill be done in like 10 seconds, pluss ill give you 2 n64 games if you say yes" So i gave her Diddy Kong Racing, and Ken Griffey Jr Baseball, and then she goes to my room. Shes a bit confused and scarred. Then i think to myself - yo i need lube right? Cuz i heard the guys on digg saying you need to lube up her clit otherwise it wont fit properly. Ok so i have no lube, but i really want to lose my virginity - so i grab some butter from the fridge, but its cold, it wont melt - so i microwaved it for 8 minutes, and then i put it in a glass and poured it on her cooter, now shes saying i burned it. I don't know what to do, my parents are going to be back any minute and shes crying in the bathroom plz help you guyz are relly smrat and please help me. Any idea how to shut her up? Should i give her a psp game?
