This repository lists most of the challenges used in the Google CTF 2017-2019, as well as most of the infrastructure that can be used to run them. IMPORTANT - The code in the 2017, 2018, 2019 and 2020 folders has unfixed security vulnerabilities. These are there on purpose, and running these on real production infrastructure is not safe.
