I have enrolled in my first CTF competition TG:Hack that took place form 08.04. to 11.04. purely online. It was a great experience, learned a lot, made new connections and the final result was amazing. Entering the competition, my goal was just to scratch the surface of the challenges. But it went very, very well so in the pot of 1000+ teams, we finished 37th.
Thanks to my teammates jetomit and EK!
I have made notes while solving the challenges, but to make them readable, a lot of work is needed. So ditch that and check out the nicely written official solutions.
