Elcomsoft Distributed Password Recovery supports both WPA and the newer WPA2 encryption used in the majority of Wi-Fi networks, allowing breaking Wi-Fi protection quickly and efficiently with most laptop and desktop computers.

Glad to see that people are finally finding ways to harness GPU power.
Not happy to see that it is making my job harder

Well, heck, most of the big security problems are pretty well understood. Think about it this way, Goose, it keeps a paycheck flowing your way! That's not to be despised these days.

I'm a veteran of the field myself, and I'm not real surprised this is happening. The Russian Mafia has probably been working on this since before NVidia released their CUDA APIs for their chips... What I find astounding is how the DHS didn't consider this a munition and limit its export.

I can guarantee you this is not going unnoticed by them now. Companies like Mitre are probably putting teams on this as we speak. But this is supposed to be a consumer product! Telling NVidia they can't export this is like telling IBM they can't offer consulting services outside the US. Very hard to accept.

And forget WPA - that's low-hanging fruit. What about cracking Triple-DES? Seems like that might be within reach now. Fortunately, there are stronger encryption algorithms for IPSec and other standards, but NVidia sems to have just given a huge new toy to crooks for them to play with...

Thanks, Wreckage, for reminding us about this. I've sent your link to inform my IT guy about this. Particularly since we work in a space where ***any*** leakage of our information could be catastrophic for us as a company...

Talk about the Law of Unintended Consequences at work here...

That's a good catch. Did you see the performance of relatively outmoded NVidia GPUs versus a Core 2 Duo??? Heck, I'd like to see the numbers for a GTX280...

Even with the ability to use a GPU, this would seem to be reliant on a weak password. WPA2 is still well fortified thanks to AES (I am not as sure about WPA1/RC4) which is still unbreakable from a brute-force perspective. If the password isn't already weak (in which case a rainbow table probably has it), you're not going to break a WPA2 password even with a small army of GeForce cards.
