HASBLCTF 2026 Reverse Engineering: All 4 Challenges Solved
Platform HASBL CTF 2026 Difficulty Mixed (Easy → Medium) OS Jeopardy — Reverse Engineering Tags Go binary triage, static-only flag recovery, PE anti-debug bypass (PEB.BeingDebugged, x64dbg process scan, NtCreateThreadEx), custom binary protocol parsing, game-logic reverse engineering HASBL CTF 2026 is a multi-category jeopardy event covering Reverse Engineering, Pwn, Web, and Forensics. This writeup is dedicated to the Reverse Engineering track — the four rev challenges (baby-go, DebugMe, Pr0t0c0l1337, PamukTheCat) were all solved, and each one teaches a different reverse-engineering skill: static-only recognition on a Go binary with debug symbols, anti-debug bypass on a Windows PE, custom binary-protocol parsing on a Linux PIE, and game-logic reverse engineering on a JRPG-shaped crackme. ...
