Introduction While searching for a CTF to participate in this weekend with my team (FF2), I stumbled upon one by accident—and it turned out to be a great find! Hosted by a group from Tokyo, AlpacaHack is a CTF platform that organizes monthly CTF competitions (rounds), each focusing on a different theme. This time, it was web security! “Treasure Hunt” (116 pts, 71 solves) Inside the challenge’s files we have the server code files along with some random files containing emojis in the Dockerfile, we can see this weird flag storing method: after pasting it to terminal, we can see that flag’s path is .

Introduction This CTF was particularly enjoyable, especially after participating in the “Flag Fortress 2” group and achieving 2nd place. I am Jonathan Levy (joe/jonathan403) and I did these challenges with my friend and teammate Thomas (thomillion) great teamwork!! “Echoes In The Dark” (450 Pts) This challenge was outstanding! The creator successfully implemented a vulnerability that he discover in the wild! and did an excellent job. Great challenge, thank you author Rotem Reiss & Shaked Klein Orbach who co-authored this challenge!
