How would I go about cracking an NTLM hash. Would I use rainbow tables, could I find one or could someone help crack this for me? What are some brute forcing options?

I used the ntlm loweralpha 1-9 rainbowtables from http://www.freerainbowtables.com In many cases bruteforcing a hash is not a good option because depending on how long the password is it can take years. Cain http://www.oxid.it/cain.html is a good hash cracker. It will dump the password hashes right from the local system. It also supports many different hash types and has other features such as a network sniffer and ARP poisoning. There are lots of tutorials or just look it up on Google.

Ok. I just started doing a lot of reading this past Saturday, after I drunkenly changed a friends password on his Vista Ultimate laptop last Friday night. It was meant as a prank on somebody that I know as the ultimate prankster. He should have had a password on there in the first place...it was completely unprotected. I have to say that I am now very enlightened and amazed at how simple it can be to break passwords (especially on XP).

Anyway, I've signed up on www.freerainbowtables.com and have begun running the client. I've also submitted the hashes that I found (just like everyone else I was let down the Ophcrack Live CD told me that I needed the NTLM hashes). I want to download the ntlm rainbow tables that are offered on the site, but the torrents aren't working.

Can someone help me break these?

Thanks!

BTW - I am on Kubuntu 7.10 x86_64 - so no Cain. I rid myself of MS products a couple years ago, and I've locked myself out of one of the few Windows machines I could have access to.

Edit - I've found the torrent that was mentioned in the 2nd post...I was looking in the wrong place before. Obviously it is going to be a while until I finish the download, so if somebody that has the ntlm tables could try these hashes, it would be much appreciated!
