FBCTF

What is FBCTF?

The Facebook CTF is a platform to host Jeopardy and “King of the Hill” style Capture the Flag competitions.

How do I use FBCTF?

Organize a competition. This can be with as few as two participants, all the way up to several hundred. The participants can be physically present, active online, or a combination of the two.
Follow setup instructions below to spin up platform infrastructure.
Enter challenges into admin page
Have participants register as teams
- If running a closed competition:
  - In the admin page, generate and export tokens to be shared with approved teams, then point participants towards the registration page
- If running an open competition:
  - Point participants towards the registration page
Enjoy!

Installation

The Facebook CTF platform can be provisioned in development or production environments.

Production

The target system needs to be Ubuntu 14.04. Run the following commands:

sudo apt-get install git
git clone https://github.com/facebook/fbctf
cd fbctf
./extra/provision.sh prod `pwd`

This will place the code in the /var/www/fbctf directory, install all dependencies, and start the server. Be ready to provide the path for your SSL certificate's CSR and key files. The password for the user admin will be printed in the console at the end of provisioning, as it is randomly generated everytime the CTF platform is provisioned.

Development

While it is possible to do development on a physical Ubuntu machine (and possibly other Linux distros as well), we highly recommend doing all development on a Vagrant VM. First, install VirtualBox and Vagrant. Then run:

git clone https://github.com/facebook/fbctf
cd fbctf
vagrant up

This will create a local virtual machine with Ubuntu 14.04 using Vagrant and VirtualBox as the provider. The provisioning script will install all necessary software to the platform locally, using self-signed certificates. The credentials will be admin/password and the machine will be available on https://10.10.10.5 by default.

Optional installation

If you are going to be modifying files outside of the Vagrant VM, you will need to synchronize the files using Unison (bi-directional file sync over SSH). Once Unison is installed, you can sync your local repo with the VM with the following command:

./extra/unison.sh PATH_TO_CTF_FOLDER

Note that the unison script will not sync NPM dependencies, so if you ever need to run npm install, you should always run it on the VM itself.

This step is not necessary if all development is done on the VM.
