Someone was logging into a vbulletin site. here is the hash

f921807556526c2de12544727aa82725


One thing I do not understand. I own a vbulletion site, and can look at the hash in the database. The hash I sniff when I log in does not match. Is the one I sniff just regular md5 and the one in the db salted?

Either way, the one above was caught on the network. If someone can crack it, I'll pay!

Another question = if I think I know part of the password, what would be the best method to try and see? Seems the more info I have the faster this should go..

From what piece of HTTP request is this hash? GET parameter? POST parameter? Cookie? Can you provide whole original HTTP request?

I don't have the entire packet. That is just what CAIN picks up each time the users visits a specific vbulletin forum. Pretty sure it is just an MD5.

I believe the vBulletin passwords in the vBulletin db are the ones that are salted, but one like this that is only used during login is regular MD5.

Please help if you can. I will pay you if that is needed.

You do need the salt to crack that hash. The hash you picked up is the salted one. It ain't a regular md5 hash.

So the one from the DB is the one that isn't salted?

They're both salted, that's the point of having a salt. If you enter a password and press the login button, your password is hashes with that salt and if the salted hash matches the salted hash in the batabase, you get access to the forum.

I know the hash can be cracked, salted or not. Someone cracked a PW for me a year or so ago, that was straight out of the vb db.

Can anyone help? How do I get the salt if that is needed?

Via brute forcing, it's possible.

Either SQL injection or direct access to the database or some other techniques.

Should the hash in the db and the one I intercept be the same? Because I have tested that and they are not.

I don't think so. I'm not entirely sure of this but I think the one in the database is hashes another time with the vBulletin licence number.
