The r2con CTF is the CTF for the r2con 2019 held during the weekend before the conference which consisted mainly of reversing challenges. I managed to solve all but one challenge (technicaly, at least...) and it was so much fun! I'd like to thank the organizers a lot for making the event happen :-)
There may be errors and inclompete sections. I tried to make a write-up for every challenge, just contact me if anything is unclear or missing!
Time to remember the best games ever!
