RE: penetration test in a Windows 2000/NT network

This sounds like a test from within the company. As it seems that
you will have physical access to facilities etc, would it be possible
for you to install something like a hardware key logger on a network
administrators workstation?

If someone has physical access to the LAN, I don't see why they couldn't
place devices on peoples systems. It may violate the rules for this
particular pen-test, but is something to think about. I see that you've
specified that physical access to Win2k systems is possible, and are
interested in not modifying the administrator account -- hardware keyloggers
seem like an ideal solution.

What about wireless sniffers? Does the target use any wireless networking
at their facility?
