Company Puts NVIDA GPUs to Work Cracking Wireless Security

arstechnica.com — There's a new application from Elcomsoft that explicitly uses NVIDIA development tools to work its magic, but the GPU manufacturer may be less than thrilled about it. NVIDIA's Compute Unified Device Architecture, or CUDA, is a set of development tools (including compiler) designed to simplify the task of coding for the company's GPU products.

  • Hamsterpotpies, on 10/15/2008, -0/+9Torrent or it didn't happen... HINT HINT
  • Ymeg, on 10/15/2008, -2/+10Hardly.

    "Brute Force Attack will take up to 128299838271 years" at 500,000 passwords a second. ElcomSoft is claiming a 20x improvement in speed, but that won't make a dent into an exponential-sized problem. See http://lastbit.com/pswcalc.asp [lastbit.com] for calculation.
  • cgibbo, on 10/15/2008, -0/+7But can it paint the Mona Lisa? Oh wait.
  • theplop, on 10/15/2008, -0/+5Real world example:
    system 1: AMD 4200+ X2, Nvidia 8800GT, 3 Gb ram = 322 Million hashes a second
    system 2: AMD 3800+ X2, Nvidia 7800GT, 2 GB ram = 20 Million Hashes a second

    I cracked a NTLM has in 3:51, completely bruteforce, the password was 6 characters long, which took over 75 Billion hashes to guess.

    Now imagine a few GTX 280's....and as far as i can tell, you can run this over the internet. So i assume you can get your friends involved too. :)


    its a bummer i cant find a crack for 2.71 :(
  • duewydo, on 10/15/2008, -0/+4At first I got a little worried, since I am operating a municipal WIFI system, but I call vaporware. Maybe in 10 more years this could be a possibility but for now I am safe. I won’t give specifics about my key(s), just that it/they is/are as secure as WPA2 will allow. Oh yeah and I change it/them regularly.

    I just don’t see how you can brute force a WIFI connection that fast. I mean even the most omnipotent super mega computer would be limited to its weak 1~50mbit WIFI connection. you can only send so much data, or attempts. I would hope the noise would become apparent (when no one else can connect to the AP)...

  • rald84, on 10/15/2008, -1/+5and yet it still won't be able to run crysis
  • cgibbo, on 10/15/2008, -1/+4But can it run Warhead?
  • JoJoDilio, on 10/15/2008, -0/+3THE CABLE IS MIGHTIER THAN NVIDIA!!!
  • JoJoDilio, on 10/15/2008, -0/+3you're too late.
  • hamobu, on 10/15/2008, -0/+3I wonder how they protect their encryption cracking software from being pirated.
  • Ymeg, on 10/15/2008, -0/+2Moonboots,

    10 upper and lower case characters at twice the speed mentioned in the article will take up to 1719 years.
  • deadmoo, on 10/15/2008, -0/+2I think the 64 CPU times 4 GPU equals 256 total GPU is a misreading of the Elcomsoft specifications. I believe that each client can have up to 64 CPU and 4 GPU, but you can have 2500+ clients in the distributed system.
  • scabbers, on 10/15/2008, -0/+2This fiendish plan can be defeated by using a cable!
  • wediggit, on 10/15/2008, -0/+2Agreed, and I'm running it......watch your keys!!!
  • DaedalusX, on 10/15/2008, -3/+5Rapidshare scene ?

    Hahahahah what a fag!
  • rowlodge, on 10/15/2008, -0/+1crack wireless ?...to get free internet or what?
  • isewise, on 10/15/2008, -0/+1Old version
  • thetinguy, on 10/15/2008, -0/+1http://www.demonoid.com/files/details/1538357/?sho ...

    your welcome
  • pcgeek101, on 10/15/2008, -1/+2nVidia pwns
  • Ymeg, on 10/15/2008, -1/+1or a few thousand years?
  • nobleexperiment, on 10/15/2008, -1/+1Well that'll make that new MacBook pro a great buy if you're into that mobile GPU cracking thing against Space Aliens.
  • pacmaann2, on 10/15/2008, -0/+0man i wish i had 500 bux to try this.......
  • moonboots, on 10/15/2008, -4/+3That's for the most complex passwords with symbols, numbers, and letters. With most wifi passwords, it should take nowhere near that amount of time.
  • LilRabbitFooFoo, on 10/15/2008, -4/+2Regardless, both of these links/stories are about a week out of date now, hello?!
  • moonboots, on 10/15/2008, -6/+2goodbye wpa2
  • PueSi, on 10/15/2008, -8/+1This will be great for the Rapidshare scene, no more missing passwords. Just leave your GTX280 SLi arrange bruteforcing for a couple of days.
