CTF Challenges (and official solutions) created for SINFCTF2020, a companion CTF for Semana de Informática 2020. This CTF was organized completely by myself, with some help for beta-testing the challenges before them going live. Here's my blogpost about organizing the CTF.
There's a folder for each challenge category, and inside them a folder for each challenge with the challenge files and a README with the problem statement and expected solution.
For the challenges in which it is relevant, a solution folder is included with a sample solution that I developed myself when testing the CTF.
Everything is Dockerized, so if you want to run any challenge you can just use the provided docker-compose.yml.
