I'm messing with a salted vBulletin hash. I have oclhashcat running trying to solve this with 212 days remaining. Do you guy have any tips for doing it quicker?

What do you use to bruteforce these kinds of passwords? |

Hey buddy
oclhashcat is a good start for that..
i would recoment also to try http://hashcat.net/oclhashcat+/
If the password is bigger than 8-9 chars then bruteforce i a bit of a hussle.
Then fingerprint attack is very handy. |

Please forgive my ignorance. What's a fingerprint attack? I'm past 8 characters in my bruteforce now with no luck so far.
I don't really see a difference in olcHashcat and oclHashcat+ Is there something obvious that I'm missing there?
Thanks again! |

There are some hashes that will probably take forever or never cracked.
What Graphics card you have ?
oclhashcat speed depends on the graphics card. |

I have a EVGA Nvidia GTX260. I'm getting about 200M/s with this card. I'm not having any luck at using the CPU's to work at cracking the md5 simultaneously. |

gtx260 good.
Do you use wordlists ? or normal attacks ?
D3ad0ne wrote a nice article on how do you use oclhashcat.

Thanks for the link. It was very informative.
I'm not sure oclhashcat+ will woth for vBulletin. I don't see md5(md5(password).salt) in the list of supported hashes. Do you know if it's supported and just not listed?
Thanks |
