After four years of team formation, we organized our first edition of Bauhinia CTF last weekend. There are over 650 teams registered and over 200 teams scored. This year, I made one crypto challenge, How to Stop Time. I also coauthored a web/crypto challenge, Amnesia, with @chthollic_.
This post is served as a short writeup of How to Stop Time, a crypto challenge with six solves during the contest period.
Asian Cyber Security Challenge (ACSC) is an annual CTF where players are competing individually, and the best young Asians will be selected form a team to represent Asia to compete with others. I ended up winning the competition among 450+ players. Unfortunately, I am unable to qualify because of the age and nationality conditions.
In this blog post, I will cover two web challenges, @t0nk42’s easySSTI (43 solves) and @tyage’s Gotion (9 solves).
idekCTF 2022* definitely has a fun and inspiring set of cryptography challenges. I played with @blackb6a and we solved 8 of the 10 crypto challenges.
In this blog post, I’ll include my solution on three of them: Primonumerophobia (10 solves), Chronophobia (5 solves) and Decidophobia (3 solves).
I prepared three challenges on behalf of @blackb6a for MOCSCTF, which is a 8-hour long CTF happened yesterday. This blogpost serves as the write-up for the three challenges that I wrote.
There are two solves (out of 40 participants) for Three-pass, and zero solves for jav-asr-ipt and Catch-22 Mini.
