    I’m Lucas Tan, a Singaporean JC2 student at Anglo-Chinese School (Independent) (ACSI) and chairman of ACSI Coding Competition Team (CCT) from 2022 to 2024.

    I love playing and winning CTFs, having achieved top positions in both local and international CTFs, like Lag and Crash, Cyberthon, Codegate Junior and others. Always excited to play more :D

    Besides playing, I’ve also organized and hosted 3 iterations of HACK@AC from 2021 to 2024, and set many challenges for other CTFs, including HackTM 2023, Cyberleague 2022 Quarterfinals, and other smaller local CTFs like BlahajCTF, Sieberrsec, Whitehacks and more.

    I main pwn and web with decent experience in both, but always looking to learn more! I’m also learning smart contract, and can do a bit of RE and misc. But I’ll never touch crypto or forens.

    I’m also a member of https://wrecktheline.com with many amazing and super teammates to learn from. ❤️

    other stuff

    When I’m not busy solving challenges, I like to do web dev. I’m quite familiar with Next.js and Prisma.

    Huge fan of the Three-Body Problem (book series)

    I use neovim btw (dotfiles here)

    Hope you enjoy my blog!
