Subject: Re: Cached NT/W2k passwords


Has anyone been able to decrypt the hash password from
the cached login on NT or W2K ?
We're is it located ? In the registry ? If so what's
the key....
I've been looking around the only thing I can find is
how to disable this feature :(

      Hi,

If you're talking about the CachedLogonsCount registry key, there has
been a
thread 2 weeks ago on FOCUS-MS :

http://www.securityfocus.com/archive/88/362946/2004-05-21/2004-05-27/0

Basically, storage is either in LSA Secrets or NL$ registry keys
(depending
on Windows version), and there is no publicly available tool to decrypt
the
hash. The stored value is a salted hash : NTLM( username +
NTLM(password)).
This is hard to crack by brute-force if password > 6 chars.
