Intro

Over the past month, I was playing the OverTheWire Advent Bonanza CTF. In the end, I ended up in 41th place and solving 11 out of the 25 challenges. So this post is a introduction to a series of writeups, in which I’ll go through every challenge I solved. So those are:

• Day 1: 7110 (here)
• Day 4: moo (here)
• Day 5: Sudo Sudoku (here)
• Day 6: Genetic Mutation (here)
• Day 10: ChristmaSSE KeyGen (here)
• Day 11: Heap Playground (here)
• Day 14: tiny runes (here)
• Day 19: Santa’s Signature
• Day 20: Strike a Pose (The heart part)
• Day 21: Battle of the Galaxies
• Day 22: Survey

My favorite was (by far) Heap Playground. Overall, it was a very fun CTF. So, see you in the next post!
