Right now (april 2008) i don't know any fast methods for Vbulletin salted hashes cracking. Rainbow tables can't be used because of salting. Only options are wordlist method and bruteforce. And because of salting cracking 6 hashes via bruteforce means 6 times more cracking time ...
Still:
a) distributed cracking can be possible, if you have access to multiple computers or some botnet
b) using GPU for faster cracking - GeForce 8800 and 9800 videocards can accelerate hash cracking hundreds of times, but such method is too fresh right now and needs more time for developement. |

| So if the salt is the same for the 6 hash, it doesnt mean 6 times more cracking time ? |

Actually depends on the attack you will choose to do. The only case that if the salt is the same you can crack it faster is when you know the salted value and you append to your wordlist the specific hash or you use hybrid-rainbow attack. but still it depends on the algorythm that is used to hash the password.
for example ..
If the web application uses this function
$salt = $%$%
$password = md5(md5($password.$salt))
you will need to write a program that :
will read from your wordlist
a
ab
abc
and append the $salted value
a$%$%
ab$%$%
abc$%$%
and then md5(md5( each of the values in the wordlist and tries to much it with the hash. If it matched then it mean you found the collission.
This approach can be used for bruteforce cracking as well. |

Sorry to bump this thread, but I was wondering if there is any program\source available for that. I have access to several computers. |

Yes, Passwordspro contains special feature for shared bruteforce cracking |
