Linux Kernel CTF

A set of scripts to help with hosting a Linux kernel exploitation CTF challenge. Deploys a challenge VM for each team.

Maintains a list of deployed VMs in droplets.json. Designed around the use of Ubuntu droplets in DigitalOcean, though it should be easy to switch out either.

Requirements

Dependencies

pip install cherrypy
pip install daemonize
https://github.com/valerylisay/digitalocean-api

Configuration

Configure challenge details in deploy.py (challenge name must match kernel module source directory)
Put DigitalOcean API key in the file API_KEY
Configure droplet details in deploy.py

deploy.py

Automatically deploy DigitalOcean droplets and install the challenge

deploy.py multiple <number>
    Deploy and install the challenge on <number> droplets (with names team1 .. teamX)

deploy.py single <droplet name>
    Deploy a single droplet with name <droplet name> and install the challenge

deploy.py ip <IP address>
    Install the challenge on an already deployed droplet

deploy.py server
    Deploy a management server so teams can power cycle their droplets
    This should only be run AFTER all droplets are deployed, as it copies over the current droplets.json

server.py

Simple HTTP server on port 80 that teams can query to power cycle their VM

/reboot?ip_address=1.2.3.4&password=password

print.py

Print out droplets.json in a human-readable form
