SECCON CTF 2022 Finals: Author writeups
I wrote all the web challenges in SECCON CTF 2022 Finals, following the Quals round. Thank you for participating in the CTF and I was glad to receive positive feedback at the after-party and on Twitter/Discord.
In this post, I describe my solution for the following challenges:
| Challenge | Category | Intended Difficulty | Score (static) | Solved / 10 (Internatinal) | Solved / 12 (Domestic) |
|---|---|---|---|---|---|
| babybox | web | warmup | 100 | 6 | 4 |
| easylfi2 | web | easy | 200 | 10 | 8 |
| MaaS | web | medium | 300 | 3 | 1 |
| light-note | web | medium | 300 | 0 | 0 |
| dark-note | web | hard | 500 | 0 | 0 |
I added the source code and author's solvers to my-ctf-challenges repository.
