Description:
With the increased growth of our startup we've decided that we should start
tagging our code releases! However we accidentally tagged one with the wrong
thing, can you find it?
git clone git://gitastic.csa.cyberjousting.com/challenge

--[ Provided Materials ]--
- Repository folder https://github.com/BYU-CSA/BYUCTF-2026/tree/main/Gitastic-Co
ntainerized/Gitastic-Solutions/Gitastic3
- Gitastic-Containerized/Gitastic-Solutions/Gitastic3/README.md https://github.c

--[ Recon / Initial Analysis ]--
This page imports the BYUCTF 2026 source material for the Git challenge Gitastic
3. The prompt is kept separate from the solve notes, and upstream artifacts are
linked so the challenge can be replayed from the original repository.
────────────────────────────────────────────────────────────────────────────────
--[ Vulnerability / Observation ]--
The useful observation comes from the imported solve notes below. I kept the
original technical path intact while normalizing the page metadata, challenge
grouping, and author attribution for the Volume 2 writeup archive.

This is to teach about git tags as an attribute in Git. You're able to easily
grep through them.
They can run git tag -l -n | grep "byuctf" to search through the tags.
