Are we talking black tar or blonde Lebanese? I prefer the hash under glass
technique although it's easier to share if you just sprinkle it over a bowl
of weed and pass it around. I think either technique works well with both
Windows and Unix/Linux environments. Although I do think the second
technique is pretty much required when working with a tiger team of "rogue
IT" specialists. I will say that the down side to either technique seems to
be a degradation of project planning and logistics.

Subject: 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
