This repository contains an example reference system for MITRE's 2022 Embedded System CTF (eCTF) - see https://ectf.mitre.org/ for details. This code is incomplete, insecure, and does not meet MITRE standards for quality. This code is being provided for educational purposes to serve as a simple example that meets the minimum functional requirements for the 2022 eCTF. Use this code at your own risk!
