arjenz/ctf-kali repository overview

⁠CTF setup in Docker

This setup is intended to create a quick working environment to play Capture The Flags (CTF), HackTheBox and similar.

⁠Setup

The easiest way to use this setup is to download docker-compose.yml and add the VPN config for the CTF; in this case, named ctf.ovpn. When those two are put in the same directory, run:

$ docker-compose up -d

⁠VPN credentials

In case credentials are required with the VPN config, create a file called credentials.txt with the username and password each on one line, uncomment the following line in docker-compose.yml:

      - ./credentials.txt:/vpn/credentials.txt:ro

And, if required, add the following line to the VPN config:

auth-user-pass /vpn/credentials.txt

⁠Usage

⁠Command line

When all containers are running, enter the Kali container using:

$ docker exec -it ctf-kali tmux -CC

From this shell any commands needed to play the CTF can be run.

⁠Browser

Challenges might involve a webpage, that's what the proxy container is used for. Run your browser through the proxy (with or without extra proxies) to let the traffic go through the VPN.

⁠Customise

Feel free to edit anything in any way. Mount other config files, add containers, anything. Suggestions can also be added to this repository.

⁠Future work

• Add option to use X11 applications, or find a workaround for it.
