Challenge - Maintaining Persistence

Maintaining persistence - The goal of the final lab is to leave a back door into the network. The choice of a print server or printer is a wise choice since they are often overlooked. We established a temporary backdoor that is installed on the multi-function to allow for ready access. this calls out to port 3943 on the 192.168.1.34 machine. Metasploit is not needed for this lab.
