JustCTF [*] 2020 challenges sources

This repo contains sources for justCTF [*] 2020 challenges hosted by justCatTheFish.

TLDR: Run a challenge with ./run.sh (requires Docker/docker-compose and might require sudo as we use nsjail extensively under the hood).

The challenges/ contains challanges directories with the following structure:

README.md – official challenge description used during CTF
run.sh – shell script to run the challenge locally (uses Docker and sometimes docker-compose)
public/ – files that were public/to download
private/ – sources and other unlisted files
flag.txt/metadata.json – the flag (don’t look there?)
solv/ – scripts and files with raw solution (used by healthcheck, if exists)
other files
