Sherlocked — CTF

Designed and organized a Capture The Flag event at Srijan 2024, Jadavpur University.

A race against time to observe, decipher, and unveil a mysterious case. Designed and organized Sherlocked — a CTF-based event at Srijan 2024, the annual Techno-Management fest of Jadavpur University.

Built the entire challenge infrastructure from scratch: the competition platform, flag submission system, challenge hosting, and scoring backend. Designed multi-layered puzzles spanning encryption/decryption, scripting, network forensics, and steganography.

The event required thinking like both an attacker and a defender — designing challenges that were solvable but non-trivial, and building infrastructure that could handle concurrent participants without leaking flags or breaking under load.
