"Windows 2000 SP3 or later and Windows XP now use a new network logon authentication method by default, the NTLM2 Session Response. Employed by Windows 2000, this unproven authentication method is considered to reduce the vulnerability found in network LM and NTLM v1 authentication. In this session, we will describe and demonstrate our audit approach for detecting easy-to-crack passwords from packets traveling on the network in real time. This approach was developed based on our thorough investigation of the characteristics of this NTLM2 Session Response. We will also discuss the possibility of attacks being attempted against Windows XP SP2 and the differences between our approach and the famous rainbow table used for analyzing Windows passwords.
