Pass the hash

I have an email hack that sends the Windows credentials, without the user's knowledge or consent, to my box - which is running CAIN. No machine in my shop will send (downgrade authentication) LM or NTLMv1 -- only NTLMv2 -- which is NTLMSSP . Using CAIN I can get the suite of NTLMSSP hashes but I cannot pass them on or crack them via brute force. Since these hashes are not the same as the hashes from the SAM - I cannot pass them directly to a RAINBOW NTLM table attack. Before I turn over the email hack to the email vendor, I would like very much to have a POC that either passes the hash or a better cracker than using a dictionary. It seems to me that the only viable hack is to somehow create a MITM situation where the authentication from my email hack is used to access some network resource (share) on a target machine where I know the email victim can access the resource via these credentials. I am hoping Metasploit or CAIN will do this one day and I know that Metasploit will pass the hash when it is not an NTLMv2 hash. Any other ideas that will leverage the hashes that I can gather - I have gathered my own hashes and verified that a CAIN dictionary attack will accurately match up a password to a hash (in other words the CAIN dictionary cracker works fine). I think that by using a very large dictionary and using all of the CAIN dictionary options I could probably crack 2-3 passwords from 200 hashes. thanks ____________________________________________________________________________________ Be a better sports nut!
