Re: Penetration Testing a Firewalled Network

[James Fryman <jfryman () gmail com>]

Have you been able to find any mail servers, and determine whether they
exist within an isolated DMZ or not?

You could send a bad email to the server and read the headers to find
out the network infrastructure. At the very least, this could allow you
to try and break into the DMZ and hop into the internal network based on
information on the DMZ (think logs).

This is dependent on the scope of your engagement, and whether or not
this is permitted.

Hope this helps!
