I'm interested in breaking wpa/wpa2 networks. I believe the only real way to do it is to capture the handshake and then try to dictionary attack it for a match. To do that, I'd need pyrit to utilize my dual GPU's.

So, who has used pyrit before? Who has any other background in breaking passwords?

That's what GPUHash.com uses:

Interesting. Looks like he's only using 2 gpu's.

What's the difference between rainbow tables, dictionary word list, and precomputed hashes?

Rainbow tables are generated by bruteforcing the hashes and storing them for later. Dictionary word lists are also a table of hashes, but smaller in size due to only including common dictionary words and permutations, not the entire bruteforced keyspace. Precomputed hashes refer to both rainbow tables and dictionary lists.

Not that I would know about war driving, but...   Wink
You can also capture enough traffic to calculate a password. It may take 2gig. of data however. On a little used system that could take a while.

That only works with WEP.

Yeah, WEP is pretty simple especially on a network with at least one user. On a good day, you can crack that in under 5 minutes. With no users on the network it takes a bit longer.

WPA/WPA2 is a whole nother ball game, lol
