The form of authentication is NTLM over HTTP. Integrated Windows Authentication uses Kerberos where possible (e.g. --if meets client dependencies like >= IE 5.5, W2K, etc.) and where not
prompts with a basic auth type box. You can submit only 'domain\user' and 'password'. In AD domains you can
often use 'user () domain tld' as well for the username (in addition to the password). I do not recall ever having to submit domain-field exclusively. You are correct, this is a result of server-side configurations done to
IIS to enable 'integrated auth'. It has been called "integrated authentication" for quite some time...at
least prior to IIS 4 IIRC. You should be able to brute this just fine with Brutus, Hydra, look at Cain & Able as well, but you will have to prepend 'domain\' to your username dictionary entries. For more, google for Amit Klein's papers on NTLM over HTTP and his papers will also link to some of the work at decomposing the specification for NTLM. -ae
For what it is worth, the current (source only) version of WebScarab available on my personal website can do NTLM authentication, as well as scripting arbitrary multi-threaded requests using the Scripted plugin. Combining these two features, you can implement your own brute force scripts. The key to brute forcing NTLM using WebScarab is to know that if you specify a Authorization header of "NTLM base64(domain\user:password)", WebScarab will automatically decompose that and use those credentials in an NTLM handshake before sending the request.

It does not go into protocol implementation details but will give you a bit more info to know what to ask google. As to how to brute force test it, I would recommend getting a bute forcer that supports that protocol. -----Original Message----- From: Bryan Miller [mailto:BMiller () sycomtech com] Sent: Friday, March 10, 2006 9:30 AM To: pen-test () lists securityfocus com Subject: OWA configurations In doing pen tests against various configurations of OWA, I have seen two major flavors. One, you receive the standard authentication request for a username and password. In those cases if you have a specific domain you can prepend it to the domain name. Other times you see the request for a username, password and domain name as three separate inputs. In the second case can I prepend the domain name to the login name, or am I required to enter all 3 pieces of information separately? Am I correct in assuming that the choice of which form of authentication you receive is set by the administrator? If I have to enter all 3 pieces of information separately, does anyone know of a tool to do this? Brutus/Hydra....tried both and neither has the option of specifying the domain name as part of the brute force attempt. -------------------------------------------------------------- ---------- ------ This List Sponsored by: Cenzic Concerned about Web Application Security?
