It's tunneled in a bastardized way through HTTP Auth: requests. You do a sort of 3 way handshake. The best reference implementation I've found is in Squid, which isn't that nice for what we want though. This is the best documentation I found on the subject: http://www.innovation.ch/java/ntlm.html -dave Jason binger wrote:
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? I have looked around to no avail. RFP says it will be in whisker 2.0 but i need it now =] Any help appreciated.
