Insomni’hack 2019 ctf results

As with every year, we've added some more room for CTF participants, reaching 500 onsite players! Another record is the number of unsolved tasks :-/. We probably went a bit overboard with the 29 challenges and it might have been a bit overwhelming for the participants.

Congratulations to LCBC for Winning the CTF, and congratulations to P4 and Dragon Sector for their respective second and third place. The full scoreboard is available on CTFTime.

The first three School teams were flagbot (ETHZ), polygl0ts (EPFL) and Securimag (Ensimag).

Here are the CTF stats, with time to solve the challenges and number of solves :
