I’m building an urgent Capture-the-Flag event that hinges on realistic Attack/Defense scenarios. I need a security specialist who can quickly deliver a small yet well-structured bundle of challenges that cover: • Network security • Web application security • Cryptography Scope – Create a handful of fresh, custom scenarios and, where it saves time, adapt proven existing ones to fit the same storyline. – Package each service or application so two isolated teams can attack and defend; containerised (Docker or similar) images are preferred for fast deployment. – Provide clear deployment notes, flag locations, and a walkthrough/solution for each challenge so I can verify everything internally. – Supply lightweight monitoring or scoring scripts so points update automatically during play. What will make the deliverable perfect? • Realistic vulnerabilities that aren’t trivial yet remain solvable within a short competition window. • Clean, commented code and configs so I can tweak difficulty later. • No external dependencies that require paid licences. If you’ve authored CTFs before—especially network-heavy or web exploitation labs—this should be a straightforward project you can turn around quickly. Let me know your estimated timeline, toolset, and a brief example of a past challenge you’ve created or defended, and we can get started right away.
