We have created a special collection of CTF challenges that will help get you into the festive spirit. There are Amazon vouchers up for grabs as well as a PlayStation 4.
The winner of the PlayStation 4 will be picked from those who have submitted the most correct answers to us, so try to solve as many challenges as possible!
On top of that, we will be giving away 3 x £25 Amazon Vouchers. Out of all submitted entries we'll randomly select 3 lucky winners - so regardless of whether you've solved one or all six challenges, you'll still be eligible to win!
The competiton will run until January 5th 2018.
The competition has now closed. If you would like to receive a copy of the challenges as well as the write-up to each challenge, please email firstname.lastname@example.org.
