Russians use GPU power to crack passwords

Russian password recovery firm Elcomsoft is using the power of graphics cards to dramatically speed up the cracking of passwords. The firm claims its GPU-powered attack can crack a Windows Vista password in little over three days. That's still quite long but much faster than the two months it usually takes with regular computing power.
With NVIDIA and AMD/ATI working overtime to raise the GPU's profile as a math coprocessor for computationally intensive, data-parallel computing problems, it was inevitable that someone would make an announcement that they had succeeded in using the GPU to speed up the password-cracking process. Notice that I said "make an announcement," because I'm sure various government entities domestic and foreign have been working on this from the moment AMD made its "close-to-metal" (CTM) package available for download. The Elcomsoft guys didn't use CTM, though. They opted to go with NVIDIA's higher-level CUDA interface, a move that no doubt cut their development time significantly.
