I have an administrators ntlm hash from xp. When I try to crack it in cain and abel I get this when starting to brute force it.
Plaintext of F4CA7D356EE... is 0307
Attack Stopped!
1 of 2 Hashes Cracked
The hash it cracked is the "NT hash" so now I'm stuck with a password that looks exaclty like this "???????0307"
How do I attack the rest of the password? Is the rest of that password an LM hash (thats my best guess)? It is exactly 7 characters missing.
Or is it an ntlm hash? I have read this stuff in school and on wikipedia and thought i understood it.
Any help on what type of hash the rest of the password is and what would be the best way to crack it?

I like freerainbowtables.com ... it is a distributed computing site that generates rainbow tables... you don't have to use their generating software to use their tables... you don't have to download the tables either, just submit the hash on their site and give it 10 mins or so... and check the pass. |

Thanks for the help everyone.
System_meltdown I went to milw0rm and the LM hash is supposed to be 16bytes these hashes are double that. So I guess its not an LM hash like i thought it was.
Here is the NT hash, F4CA7D356EE41CD859A26C49A31B2F9D
and this one is labeled in cain and abel as LM hash 0259752D2C3B4F13F9496BE7EBA6D251
I'll try rainbow tables next and if that doesn't work I'll run them through jtr and see if I have better luck.

How did you get the hash? Pwdump? If so, post the full output from it.
I would also reccomend freerainbowtables.com.

Yes it is ^^ passwords longer than 7 characters are split up in two LM hashes; that's why they're so damn easy to crack compared to NT hashes

Just use JTR. A good wordlist will crack it in seconds.
PS: I would learn more on ntlm hashes. (Your comment on milworm's
error)
