This is a modified version of a CTF challenge I created internally at Meta before I left for OpenAI in February 2024. (The original version referenced internal tools that made it unfit for public consumption.) The category is Misc/Stego (so don't go trying to DDOS anyone!) and the flag format is fb{} for old times' sake.
Note: if you stumbled upon this repo by chance, start from this Threads post to experience the full challenge.
