Does anyone know of a tool or script out there that can brute-force NTLM web authentication that may be used on IIS or ISA server. I know IE explorer is the only browser that supports this auth method. Does anyone have any papers or link on how exactly it works? Is it just tunnelled using HTTP? Or does it use windows auth ports like TCP 139 etc?
You may take a look at fetchmail, it can make NTLM auth to IMAP servers. A long time ago I tried to do it manually against an IIS and the same way worked fine. I then wanted to write a patch to lynx to do ntlm auth but never did it :( You have to get the algorithm in fetchmail and may get some code from fetchmail or from titi "a set of password crypters" <http://www.groar.org/groar/#s4> (last test version is stable ;) .
