Gameplay
Participants will complete a series of cybersecurity-related challenges sequentially in increasing levels of difficulty.
Challenges will test knowledge across domains such as Pwn, Web Penetration Testing (Pen-testing), Mobile Security, Forensics and more.
By popular demand, participants will be able to choose their own adventure again this year on a split-track gameplay system!
Upon completing the Level 5 challenge, participants have the option to solve Reverse Engineering and Pwn challenges (Track A - Levels 6A and 7A), or Cloud and Web challenges (Track B - Levels 6B and 7B). Both tracks will converge again at Level 8.
For further details, refer to FAQ (S/N 20).
