Advent Bonanza 2018 CTF

OverTheWire organized the OverTheWire Advent Bonanza 2018 CTF in December 2018. Just like in an advent calendar, which gives one chocolate per day between 1 and 25 December, this CTF released one challenge per day as well.

The CTF VM is now hosted in the warzone to give everyone a chance to play the challenges at their own pace.

The results of the CTF can be found on CTFTime.org. Congratulations to the top 3 winners: kainashi, Tasteless and WTFH4X!
