Smart Password Mutations Explained

Wednesday, April 15th, 2009

Strong 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.

Great hot water supply

Google made a video tour inside their premises. Looks like an amazing wire-n-hardware gathering:

Oh, I wish we could rent this mass of metal for password cracking purposes! In that case, however, water cooling system would not be enough to chill all our graphic cards. Better to think of a way for heat-utilization, like channeling hot water to the nearest residential neighbourhood and  “use it as heating source for buildings in the area” as suggested by Anonymous in Seth H. Weintraub’s blog, or at least open Russian bath near it :)

Nvidia Quadro FX 4800

You 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.
