SUNCTF 2026

about

SunCTF is Sunway Cybersecurity Club's flagship jeopardy capture-the-flag competition, now in its third edition. Teams face a board of standalone challenges across Cryptography, Web Exploitation, Binary Exploitation, Reverse Engineering, Forensics, OSINT and Miscellaneous. Scoring is dynamic, so challenge values decay as more teams solve them and the scoreboard shifts in real time. Every challenge is authored in-house by our members and alumni. All challenges are open-sourced after the event, with official writeups published for each.
