AI Village Capture the Flag @ DEFCON write up

 In August 2022 I had the chance to participate in an AI-themed CTF collocated with the DEF CON 30 security (hacking) conference. This was particularly interesting since it was presented in a novel format as a Kaggle competition where the leaderboard was ranked based on the points that each of the discovered flags was providing. Despite entering the competition in its latest stage I did manage to solve all the challenges but two, therefore achieving the second best score (although my final ranking was lower due to submission times being used as tie-breakers). No one was able to find the last flag corresponding to the Crop-2 challenge until after the CTF ended.
