×Mission Briefing
Objective
Four challenges, each built on the real Apollo 11 guidance computer (Luminary 1A, rev 099). Each one hides a single flag in the form CTF{…}. Recover all four.
No brute force
Every flag can be recovered by understanding the data you are given — no guessing, and no need to attack the server. Everything you need is on this site or linked from a challenge brief.
On AI assistance
These challenges are built for humans, not language models, and leaning on an AI to solve them defeats the whole point — please don’t. Using AI to take notes or keep yourself organized is fine; using it to do the reverse-engineering for you is not. Solve it yourself — that’s the fun.
Confirming a flag
The Flag Verification box tells you whether a flag is correct. It is only for your own confirmation — it does not submit your entry, score you, or track progress.
How to win
This is all-or-nothing, first place only. When you have all four correct flags, send them in a Discord DM to:
@themikeconnor
The first person to DM all four correct flags wins. Partial solves do not place.
Hints
Hints are available for every challenge — just ask. There is an expectation that you can show your work and the attempts you have already made before a hint is handed out.
Conduct
- Don’t share flags or write-ups until the competition closes.
- Don’t attack, scan, or try to break the hosting — the puzzles live entirely in the provided files.
- Read the code comments. The original Apollo engineers left some good ones.
- Bribery is explicitly allowed.
