Jumping the gun I know since there is no verification but this, if true, is totally world changing, isn't it?

- shutter 18y agoThe article noted this: "They faulted cost pressures on keyboard manufacturers for not making keyboards more snoop proof." So if this is true, at least it appears that new keyboards could be improved to block eavesdropping.
- maximilian 18y agoIt would probably be pretty easy to kill the EM emanating from the keyboard. If all the circuitry was surrounded by tinfoil and the cable had better shielding, it'd probably cut the radiation a lot. If anything, i'd bet its the cable that does all the radiating? I'll have to think about that one a bit. Its totally badass though. I kinda wanna go home and build something like that. Probably harder than it looks though.
- pmorici 18y agolooks like they used a USRP.
- pmorici 18y agoNot really. Attacks against unintended emissions have been around for years, whats one more for the pile. The other thing I would question is wether or not this can actually capture and decode the signals at actual typing rates versus the hunt and peck speed demonstrated in the video...
- khafra 18y agoConsidering researchers have been able to read CRTs without looking at them by Van Eck phreaking, and more recently even get LCDs (http://www.omninerd.com/news/TEMPEST_Attack_on_LCD http://www.omninerd.com/news/TEMPEST_Attack_on_LCD) it's not really even game changing for a realistically secured facility. http://www.tscm.com/TSCM101tempest.html http://www.tscm.com/TSCM101tempest.html is a primer, and http://cryptome.org/nsa-tempest.htm http://cryptome.org/nsa-tempest.htm is an in-depth guide, if you think it's worth your time and money to mitigate this kind of vulnerability.
