CTFd Fetch

Often it would be nice to download all the challenges (descriptions/files/etc) from a CTF so that you have them for future reference, or to have offline, or to share with a team.

That's all this script does.

Since many CTFs have standardized around CTFd as a platform, we use that as a starting point.

Caveats

• Use this tool considerately. It makes every attempt to respond sanely, and only download things not already downloaded, but make sure you are not abusing the good will of a CTF Host/Organizer.
• This tool primarily uses the JSON response from a CTFd endpoint (/challs). Any changes to CTFd have the potential to break this tool.

Quick Start

Install.

pip3 install ctfdfetch

Download all the challenges from a CTF into the current folder.

ctfdfetch --server https://ctf.example.com --user hacker

For more options such as out directory, nested categories, verbosity, etc).

ctfdfetch -h
