Qualifiers I participated in Hacktheon Sejong CTF 2023 under the c'est la vie team. The CTF this year is very guessy and do not involve high level techniques. Hence, I pretty much got carried (helped the team a bit though). The solution to the only Crypto challenge I attempted is solution with a lot of guesswork. There is another Crypto challenge, but it is in Hangul - the writing system of the Korean language, which obviously I have no idea of.
