CSSA CTF 2026 Challenge Repository

This repository contains an archive of the source code, resources, docker configurations, and solutions for all* the CTF 2026 challenges

Server Infrastructure

This year's CTF's hardware was sponsored in part by Glitch Secure. The server that they gave us access to had an AMD EPYCprocessor and quite a bit of RAM, but we ended up using less than 32 GB of RAM during the entire event. This included running all* of 21 challenge Docker containers, the CTFd instance, and all of the 40 provided Challenge Box VM's that we were able to provide thanks to Noah (@noahc3)!

We were provided 3 public IP's from Glitch Secure, and used those to split the network into 3 segments.

1. CTFd Instance
2. Public entry to Nginx Proxy Manager for our challenge VMs (this included not just web traffic but also TCP traffic)
3. Challenge Boxes

We hosted our docker containers using Dockhand in an LXC container on Proxmox. The docker containers were uploaded to the GitHub Container Registry and should be linked to this repo.

Challenge Creators

The challenges were made mostly by Alumni (@HellSpy @noahc3 @edwinduong) and Current/Former Team members (@2Lazy2BeOriginal @Tlmmy8246 @arasantos @FopefoluwaIkufisile)
