Challenge Binaries

If you're interested in playing on the exact challenge binaries used during each round, you can either build them yourself as described below, or look in the handouts/ subfolder of the release.

Challenge structure

Building challenges

1. ./livectf.py build <challenge>

Managing challenges

Challenge management (creation/building/starting/stopping) is done through livectf.py, which is a light wrapper around docker. See ./livectf.py --help for usage.

Adding a challenge

1. ./livectf.py create <challenge> will copy the template challenge to a new challenge directory.
2. Add your challenge source in <challenge>/challenge/src
3. Update the solution script in <challenge>/solution/solve.py

(For challenges that include more than one source file + one binary):

4. If needed, edit REQUIRED_PACKAGES in <challenge>/challenge/Dockerfile to include any extra build/runtime dependencies
5. If needed, change the build commands in <challenge>/challenge/build.sh
6. If needed, change HANDOUT_FILES in <challenge>/challenge/build.sh

Adding a solution for a challenge

1. Add any pip requirements to <challenge>/solution/requirements.txt
2. Put your solution script in <challenge>/solution/solve.py
