Lead Challenge Creator: OPUCC26
Result
I served as the Lead Challenge Creator for OPUCC26, a 24-hour internal CTF competition involving 48 teams from UiTM campuses across Malaysia.
I personally created 17 of the 46 challenges used during the competition.
My contribution
I was responsible for designing, developing, testing, and preparing challenges across several formats and cybersecurity categories.
My challenge work included:
- Digital-forensics investigations
- Reverse-engineering challenges
- Network packet analysis
- Discord bot interactions
- RPG Maker MV security puzzles
- Roblox-based cybersecurity challenges
- Miscellaneous interactive challenges
- File-recovery and steganography scenarios
In addition to challenge creation, I supported the live operation of the event by:
- Monitoring challenge availability
- Responding to participant sanity-check tickets
- Investigating reported challenge issues
- Coordinating fixes with the infrastructure team
- Verifying intended and unintended solution paths
- Supporting CTFd and container-based challenge deployment
- Helping troubleshoot technical issues during the competition
Why it matters
This achievement demonstrated my ability to create cybersecurity challenges at scale while also supporting a live competition environment.
It required technical knowledge, creativity, testing, documentation, communication, and the ability to troubleshoot problems under time pressure.
The experience also taught me that successful challenge design is not only about difficulty. A good challenge must be reliable, fair, understandable, and resistant to unintended shortcuts.
