Welcome to the Christmas Special Event by Cybersecurity Society ULGC. This Christmas, solve some easy-peasy challenges and win cute gifts!
How it works:
- Challenges will be released here and on the Discord server.
- All challenges will be released on
Christmas Eve @ 3:00 PM BST. - All challenges are beginner friendly, we want you to have fun and learn something new!
- This event resembles a CTF, once you solve a challenge you will get a flag in the format
christmas_carol{flag}. This is the “answer” of the challenge.
Flag submission process:
- Once you have solved all challenges, submit the flags in the
Google Formshared alongwith the challenges. - People with 100% correct solves will win super cute gifts! These gifts include a cool banner with your name/username to post on Linkedin and a badge to use on your profile picture.
- Some challenges do not give you the flag even after solving it since it will be too easy. Once you solve such a challenge, ping
@ghalibluvron Discord and we will give you the flag.
