NuttyShell is more than a hacking club; it is a community driven by collaboration and mentorship. Their journey spans intense, multi-hour marathons like the HKCERT CTF, where staying focused meant supporting teammates the moment they got stuck. Senior members stepped up to teach defensive thinking to those with zero blue-team experience, while others used their web development backgrounds to build their Open CTF frontend. Supported the team’s technical anchor, coach Hopkins Kong, we developed vital leadership, communication, and time-management skills. Having benefited immensely from the cybersecurity ecosystem ourselves, hosting the annual PolyU Open CTF is their way of giving back—creating real opportunities for others to challenge themselves and fall in love with cybersecurity.
