According to the description:  "The SoundStation IP 5000 boosts productivity and reduces listener fatigue by turning ordinary conference calls into crystal-clear interactive conversations."  Looks like you can still get them from CDW for about $500 although you can get them used for about $20-30.  With the latest firmware, this unit is vulnerable to cross site scripting and session hijacking.  Then again, the session hijacking part is not really required because of yet another issue but I'll get to that shortly.

In an ideal world, we have access to all of our tools but things being what they are, eventually we will find ourselves in a situation where we our separated from our attacking server.  Let's say you takeover a host and you need to enumerate from that host which doesn't even have Nmap?  First we need to find targets and once we find targets, we need to enumerate each target.

Let's say we have a small hole into an environment, like a web server sitting behind the firewall with a port open to the Internet.  We compromise the web server and from the web server, we can see other targets in the environment but we are unable to see those targets directly from our attacking machine.  We need a way of pivoting through that web server in order to attack those targets and that's where we can use Proxychains. 

In this first image, I'm getting ahead of myself a little bit but I wanted to paint the picture.
