ATI, NVIDIA and WPA/WPA2 passwords

Friday, April 10th, 2009

In 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, 2009

You’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.
