The DEF CON CTF 2022 Qualifier

This repository contains the open source release for Nautilus Institute's 2022 DEF CON CTF qualifier.

We are releasing all of the source code for every challenge that was released during the game. In most cases, this also includes all of the code required to build that source code into a working challenge (such as Makefiles and Dockerfiles). It does not include the infrastructure required to host those challenges (e.g. our CI/CD pipeline, deployment scripts, and the gatekeeper binary that validates tickets).
