International CTF Finals Content
CTF Challenge Development
Designed CTF reverse-engineering challenges as a curriculum pipeline, where each level trained a specific reasoning step instead of only increasing difficulty. We emphasized educational progression, infrastructure reliability, and anti-cheese challenge design.
System Architecture
Challenges are authored in C/C++ and Assembly, utilizing custom obfuscation layers and system-level vulnerabilities. Deployment is containerized via Docker and exposed through xinetd to ensure process isolation and high availability on competition infrastructure.
Implementation Strategy
Designing non-trivial vulnerabilities that bypass automated solvers, optimizing challenge-side anti-debug logic for remote environments, and managing resource constraints on high-traffic CTF infrastructure.
Technical Outcome
Produced original competition content for international security events, focusing on binary security research and pedagogical challenge design.
