Hits: Failed to execute CGI : Win32 Error Code = 3

During an assignment, a client asked about the risks of losing a configured laptop :-) There are at least two (bad) things an attacker can do to obtain access to the WaveLan:
SMBProxy is a "Passing The Hash" tool that works as a proxy.It makes it possible to authenticate to a Windows NT4/2000server by only knowing the md4 hash. It also makes itpossible to mount shares, access the registry and anythingelse you could do with that particular users privileges.The theory behind this is pretty old, and I don't take any credit for it. The tools for doing this though, have been quite limited. That's why I decided to release this proxy, to really demonstrate the magic of "Passing The Hash".
It succesfully intercepts communication with Windows NT 4.0 and Windows 2000. It looks for the username trying to connect and does a lookup in the pwdump file for the users hash. Currently it only intercepts the NTLM hash.
