Breaking NTLM with precomputed tables

The following screenshot depicts a proof of concept implementation that accepts
an incoming CIFS connection, goes through the protocol negotiation phase with
the connecting client, sends out the static challenge, and disconnects the client
after receiving username and NTLM hash from it. The server also logs some
more information that the client conveniently sends along.

That’s a Windows XP machine connecting to the rogue server running on Linux.
The client is connecting from IP address 192.168.7.13. The username is “Testuser”,
the name of the host is “BarrierIce”, and the password hash got captured
too of course.
