Last month, I created a writeup about how to reverse engineering binary compiled with QuickJS JS Engine. My approach was to modify the QuickJS codebase to force it to dump opcodes by providing bytecode from compiled binary. Check out the details at kos0ng.gitbook.io/ctfs/write-up/… #CTF

Just finished writeup about reverse engineering Unity game and XDP program (eBPF). Interesting challenge from DeadSec CTF 2025, check my writeup below : blog.ryukk.dev/write-up/2025/… (previous tweet wrong URL lol, can't edit)
I attended the SECCON finals with "ADA INDONESIA COY", really enjoyed the CTF day and was happy to meet some friends there!
