According to The Inquirer, Nvidia GT300 promised in October. Should be a good video card for GPU-accelerated password cracking

Monday, April 20th, 2009Password cracking with Microsoft cofee
Thursday, April 16th, 2009No, it’s no a typo . COFEE means Computer Online Forensic Evidence Extractor, actually. Never heard about it? Then read Microsoft supplies Interpol with DIY forensics tool. Just don’t ask where to get it. We have not seen it either.
NEW: Rainbow Tables for password-protected Excel spreadsheets
Thursday, April 16th, 2009And now…. we have Rainbow Tables for Microsoft Excel docs with 40-bit encryption. So, it became possible to reach near-instant recovery of 97% of spreadsheets created in MS Excel 97-2003. Unfortunately, due to specificity of Excel spreadsheets format it’s unreal to get 100%-recovery, still, you can use brute force to cover the rest 3%.

Microsoft Office 14
Thursday, April 16th, 2009According to CNET News, Office 14 technical preview will be available in Q3, and release version in the first half of 2010; Office 2010 will come in both 32-bit and 64-bit versions.
If password encryption will be improved there — of course, we’ll update Office Password Recovery accordingly. Though it is already good enough in Office 2007 — even with GPU acceleration, the password recovery speed is only thousands passwords per second (see some benchmarks at Distributed Password Recovery page), so even relatively short passwords are secure enough.
Smart Password Mutations Explained
Wednesday, April 15th, 2009Strong passwords are mutated passwords. Everyone who publishes recommendations on creating secure password says that you have to use both upper- and lower-case letters and inject some tricky special characters. Such recommendations may result in p@$$words and pAsswOrds, and p_a_s_s_w_o_r_d_s. The fact is that modern password recovery software uses dictionary attack to get one’s password back. Dictionary attack means searching lists of dictionary words and common phrases that can be found on the Internet or delivered with the software. It is easy to grab that dictionary words and word phrases make bad passwords, but one has to understand that adding special characters to these words and phrases does’t do them any good. Such password can be easily cracked when smart mutations option is on.
We give you a tip on word mutations implemented by modern password cracking tools, so that you can create really strong passwords for your files and accounts.
Nvidia Quadro FX 4800
Wednesday, April 15th, 2009You should be aware that Distributed Password Recovery and Wireless Security Auditor work not only with NVIDIA GeForce cards and Tesla supercomputers (in terms of GPU acceleration), but with professional Quadro cards, too. We never compared the performance of GeForce and Quadro, though. Curious? Then read the Nvidia Quadro FX 4800: Workstation Graphics At Its Finest? article published at Tom’s Hardware today.
Technically, Quadro FX 4800 is very similar to GeForce GTX 280. But have a look at the Performance Comparison. On some tests, Quadro is up to 10 times faster than GeForce. Yes, almost the same GPU. Yes, same version of drivers. Amazing. Just note that the retail price on FX 4800 is in $1600-$2000 range. But if it can do password cracking at much higher rate than GeForce (again, we never tried it, sorry), it looks like a good investment.
ATI, NVIDIA and WPA/WPA2 passwords
Friday, April 10th, 2009In case if you missed it: new ATI Catalyst drivers (9.4) now available (you can read the release notes for details). For some reason, some driver files have been renamed (well, not in 9.4, but in 9.3 released a bit earlier, though that version was really buggy and we cannot recommend to use it anyway), and our WPA password recovery (audit) software was not able to recognize Radeon cards anymore.
Well, to make the long story short: simply download the latest ATI Catalyst drivers and updated Elcomsoft Wireless Security Auditor . Just note that this (new) version of EWSA will not work with drivers version 9.1 or older.
In the meantime, NVIDIA CUDA 2.2 (beta) released. Does that actually matter? Yes, because NVIDIA Tesla C1060 and S1070 are now officially supported on Windows. Besides, we need to have a look at Zero-copy support for direct access to system memory, because it may speed-up the GPU-enabled password cracking on some particular algorithms.
Lotus Notes ID files password cracking
Friday, April 10th, 2009You’re probably aware that our Distributed Password Recovery works with Lotus Notes ID files (as well as with two dozen other file formats, of course). Some sad news: in latest versions of Notes (8.5), encryption has been improved. In older versions, only 64-bit and 128-bit RC2 options were available, but now you can also use AES (128-bit or 256-bit). Well, encryption itself does not actually matter, but the problem is that password verification routine is not much better (worse?) as well: 5,000/10,000 SHA-1 cycles have been added. EDPR will be updated accordingly to support new format (you can subscribe to our mailing list to be notified), of course, but don’t expect the high recovery speed: we can get several hundred passwords per second only. For older versions of Notes, the speed was ~100,000 passwords per second or higher.
23 NVIDIA GeForce GTX 295s packed into one system
Wednesday, April 8th, 2009Looks like a very good system for password cracking (using GPU-accelerated Elcomsoft Distributed Password Recovery), isn’t it? Especially assuming that even single GeForce GTX 295 is faster than Intel Octa-Core CPU (to be released later this year).
WPA Benchmark
Monday, April 6th, 2009Here are the benchmarks for WPA recovery; we’ve run tests on one of the most powerful modern CPUs and a bunch of GPUs. Even GTX 280 outperformed Core 2 Quad Q6600:
