RainFall

What this is

RainFall is the second security project at 42, it's organised like a CTF with levels.

This project focuses on exploiting binaries, mostly using buffer overflows.

How to use

Before anything, run make, a helpful description of every command will show up.

• If you are running linux and have libvirt (and virsh, dnsmasq, ebtables): just run make start ;)

• Otherwise you will need to download the projects ISO: make RainFall.iso and then setup a VM yourself. Using this method you won't be able to use:

  • make start
  • make stop / make shutdown
  • make ip
  • make list-vm
  • make network

You will then be able to connect to the virtual machine through ssh.

How to connect through ssh

user=level0 # level0 to level9 or bonus0 to bonus3
ip=192.168.122.237 # The ip is given by make start, make ip, and by the VM itself when it starts
ssh -p 4242 $user@$ip

The password to user `level0` is `level0`.
The password to user `level1` is in level0/flag
The password to user `level2` is in level1/flag
(...)
The password to user `bonus0` is in level9/flag
