Hey guys,
Got myself some hashes to a vBulletin forum (by long and extensive drawn out blind sql injection), a few of which I wasn't able to crack on my own. I'd fully appreciate any help I could get on these.

User1:d110fd8ed0f59cc2c41f16294fadb7dc:k}s
User2:8d6d9bfd7e59a2b6b284f0e3e944542d:BXu
User3:b6985de9bd34ff3c185a5375f4f25574:Z_,
User4:4cadc0ec06c89f83a3c69f3ec1f78a2c:Zsn
**This last one uses a larger charset than a-z 0-9 1-7 chars

The method of salting is:
MD5(MD5(password).salt)

I've cracked a few of the easier ones (see below) already so I know that I'm at least on the right track, these just happen to be a little harder passwords is all.

Examples of ones I've cracked already:

User5:9da5766cfd7b893e4082f0b1e5d366fd:9sQ --> tom927
User6:e28670a3feada212595e15f434375530:(?7 --> 123456
User7:ee8b266c5cf1edbd303ffe88e7f92ce9:\X" --> qweqwe1

I'm fairly certain that these users use the charset a-z 0-9, but I could be wrong.

Thanks in advance for any help!

Thanks very much, waraxe, that was really helpful. Any chance on those last two passes or were they not found?

Oh, and one more, I just got the administrator/owner's hash and salt out of the database (you wouldn't believe how time consuming it is, I custom write about 4-5 queries per character of a 32 character hash Shocked

Anyway, waraxe (and possibly some other nice fellows), is there a chance you could give it a try?

Thanks again, I really appreciate your work. Also, I wonder if it would be possible to learn exactly how you crack your passwords and with what wordlists/rules exactly (unless that is, you would rather keep that a trade secret, which is fully alright by me)? Once again, thanks.

m using inside's passwordpro and the dictionary set provided on the following page.

btw, simple dictionary attack didn't revealed anything regarding the above hash...

and would you like sharing your technique? (either on the fora or pm, whatever is suitable for you) if it isn't a trade secret Smile

Yeah, I could do that for sure. Tomorrow happens to be my worst day of the week though, so I might not get around to writing it all down by then, but hopefully by Friday. Hopefully it could get someone to write an automated program to do it (I would, as I know programming pretty damn well, but unfortunately, I don't know how to code for and deal with sessions in php, a necessary step for this particular exploit.

In the meantime, any help someone could give on this hash would be greatly appreciated. One of the hashes above went to a former admin's account (but he has no powers anymore Mad ).
