To locate the core and eradicate its grip at the heart of our cyberspace, participants must sequentially complete a series of cybersecurity related challenges that increases in difficulty.
Challenges will test
knowledge across domains like Pwn, Web,
Forensics, Reverse Engineering, OSINT, and Cloud Security.
This year, participants can once again choose their own adventure with our split-track gameplay system!
After completing the Level 6 challenge, participants can choose between Track A, featuring Cloud/ Web-focused challenges (Levels 7A and 8A), or Track B, which includes RE-focused challenges (Levels 7B and 8B). Both tracks will converge again at Level 9.
