hello,
rainbow tables on freerainbowtables are much limited on mscache (since per
login hash). Mainly only for the well known "administrator" account

Hash: SHA1
Download Cain & Abel from www.oxid.it, that should enable you to
crack the password hashes in question.
Rainbow tables are available at www.freerainbowtables.com, where you
can also participate in generating tables by running their
distributed table generator.

Emne: Brute-forcing cached Windows login password hashes
Greetings all,
My question is regarding the encrypted password hashes that Windows
stores in the registry of the last 10 logins to a workstation.
I read the original white paper written by Arnaud Pilon and I've used
his cachedump tool to extract the password hashes from the registry.
What I'm wondering is what type of hash those passwords use. Is it
straight MD4? I know that each hash is salted with a machine-specific
unique string. What I am unclear on is what exactly the password hash
is and how it can be brute-forced. I know that there is a patch for
John the Ripper, but every mention I can find refers to a two year
old version of John. Does anyone know if the most recent version has
this patch in it already? Also, is anyone familiar with any rainbow
tables for cracking these passwords? Are rainbow tables possible for
these hashes because of the salting?
Thanks all.
