As mentioned in the email from Mark Ng, L0phtcrack will be your tool. One of the scenario's you could try is to take a laptop, install l0phtcrack on it and put it with a valid ip-adress in the network (most of the networks do have dhcp, so that won't be the hardest). Next you have to setup L0phtcrack in "listening/sniffing" mode. Also create a shared directory on this machine.
From your station you will send around an email which contains an URL (which
will connect towards the share). Make the email attractive so people are triggered to click. When clicking to the URL,Windows will notice that it's a Share and sends the NTLM hashes. If the network is switched, you have to use a combination of the tool Ettercap and later on L0phtcrack to decrpt the passwords. You can use Ettercap the spoof (be carefull) the switch, so all ports can be sniffed. Choose for storing the sniffed traffic towards a file. This file can later on be analyzed by L0phtcrack.

Hi, I will accomplish a penetration test in a Windows 2000/NT network shortly.
A
goal is to get confidential information (files) and if possible get admin rights. I will be with my computers in the LAN. A computer for normal uses
(thus
no Admin access) is likewise put to me at the disposal. Is there a possibility on a Windows 2000 computers (physical access is
possible)
to attain admin rights without to overwrite the admin account. Background:
I
would like try to crack the password of the local admin (e.g. by means of
pwdump
and John). There ist the possibility that all admin passwords (also for
the
domain) is alike. Is there a tool, with which I can crack NTLMv2 hashes. Background: I will
try to
sniff hashes during the registration at the DC (e.g. CAIN, ettercap) and
to
crack them. Unfortunately me is still no tool known in order to crack
NTLMv2
hashes. A further possibility at to come to information, would be the employment
of a
SMB Proxy. By ARP Spoofing it would be nevertheless theoretically possible
to
intercept the LM/NTLM(v1/v2) authentication . Then the attacker could
itself
instead announce at the server. Does it give there already such a Tool? Who has suggestions? For Tools please give always in the Web URL (if
possible of
the programmer). Greeting Heron __________________________________________________________________ Arcor-DSL Flatrate - jetzt kostenlos einsteigen und bis zu 76,18 Euro
