Foreword I participated in HackTM CTF 2023 with NUS Greyhats. We managed to get 15th place. Overall I am quite happy with my performance this CTF, I managed to solve 1 challenge solo and collaborated with mechfrog88 to solve another Crypto challenge.
The Crypto challenges of this CTF are quite tough, and it is an interesting read of the solution given by the creator. I think the given writeups by the author are good enough, and should provide a better view of the educational values after solving the challenges.
Foreword I participated in Insomni’hack 23 with NUS Greyhats. We managed to get 12th place. I was in the Lunar New Year celebration mode and basically got carried by the team. I only look at one challenge in the Forensics category. I did not manage to solve it, but I will document (briefly) how we do to obtain the solution.
Challenges Autopsy Big kudos to IDissEverything of NUS Greyhats for solving this.
Foreword My first non-NUS CTF! I was mostly carried by the insane people @ NUS Greyhats.

Find A tough OSINT challenge. Initially we are only given the following image.
There was initially no clues given by the challenge organizer.
