About

Hello world, I am Isopach.

I post writeups here for CTF challenges and CVEs I’ve found in the wild.

On the CTF side, I played for CTF.SG, a Singaporean team, specializing in Web/Misc/Forensics between 2020-2023, and OpenToAll (OpenBlue for Defcon China) before that from 2018-2020. I’ve mostly stopped playing now, but the writeups stick around.

These days I spend more of my security time on vulnerability research — you can find my CVE writeups here. I also take on security consulting work through Isopach Pte. Ltd.; reach out if you’re looking for help.
