If there's one thing I learned during the whole competition, I don't really know binary exploitation too well and I certainly hope to be able to improve on that before the next CTF comes around. From conversations with the challenge setter (@nnamon), I learned that while modern systems are not vulnerable, IoT products given limited processing capabilities and storage capacity, are much more vulnerable to binary exploitations, so that's something interesting.
I originally intended to join this competition as a solo player but because of team size requirements, I recruited @zst123 (Manzel) and two other people just to meet the team size of 4. Throughout the competition, I've also come to realize that having more minds equals to having more perspectives to take on challenges, especially challenges of a black box nature. @zst123 has helped a fair bit in giving his own perspective and that I appreciate greatly.
To sign off this reflection, I would like to add how salty I feel about team TRiggeRed utilizing hidden flags at the last minute. Very very salty.
P.S. @Deathline78 should be banned eternally from setting challenges.
Sincerely, Amos Ng @LFlare
