The Hidden Quest
Original Writeup on seall.dev
The description hinted at that they had hid the flag somewhere in a recent socialโs post. I go to the KnightCTF website, and they only have three socials linked Facebook, Twitter and YouTube.
This challenge was essentially just looking through all recent posts on all socials very carefully, and you will find a Facebook post has a flag in the image in the top left.
