Google CTF 2018
Moar
Finding yourself on the Foobanizer9000, a computer built by 9000 foos, this computer is so complicated luckily it serves manual pages through a network service. As the old saying goes, everything you need is in the manual.
nc moar.ctfcompetition.com 1337

nc moar.ctfcompetition.com 1337 |
First I create connect.sh for easy to use “nc moar.ctfcompetition.com 1337” but it is not necessary.
When I use this command “man” page is opened. Man pages give us opportunities to use ! for a unix command line.
For example when typing “!ls” is working and show current directory item list.
After spending a little time in directories I found the CTF code in “/home/moar/disable_dmz.sh” file

This is the easiest question until now.
