justCTF [*] 2020 challenges sources

Overview

justCTF [*] 2020

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
