GCW 2.0 Challenges - by zennova

Welcome to my challenge repository for Gunadarma Code Week (GCW) 2.0.

This repository contains the source code, public distribution files, and complete writeups/documentation for the challenges I created as a problem setter for the event.

Repository Structure

The challenges are organized by their respective stages in the competition:

🚩 Quals

• BlackWallProtocol - A chained forensic and reversing artifact challenge involving hidden FAT12 volumes, repaired 7z archives, and memory dump analysis.
• CanonCollapse - A chained steganography and reversing challenge involving BMP/ICC metadata, routed high-word pixel streams, and an E42C container.

🏆 Final

• LostInTranslation - A two-stage Miscellaneous challenge involving a timed speed-math/hex programming test over a socket, followed by an esoteric stack/accumulator-based language interpreter.

Each challenge directory contains its own respective documentation (writeup.md), challenge files, and solve scripts.
