Iron Forge CTF 2026

Built by Iron Forge, hosted on Terminal43

Iron Forge CTF 2026 is the work of the Iron Forge team, the people who design and build the challenges. It runs on Terminal43, which provides the platform and infrastructure: they bring the puzzles, we make sure everything runs smoothly so you can focus on solving.

Whether you are chasing the top of the scoreboard or learning by doing, Iron Forge is built to meet you where you are and push you one step further.

What to expect

• A focused 6-hour sprint - one sharp window to solve as much as you can, no multi-day grind.
• Challenges across every category - web exploitation, cryptography, reverse engineering, forensics and pwn.
• A difficulty curve for everyone - approachable tasks to warm up, and hard-hitting ones to separate the field.
• Jeopardy-style scoring - solve, submit your flag, watch the live scoreboard move.
• Hosted on Terminal43 - no extra setup, no new accounts, nothing to install.

Who it's for

Students, self-taught hackers, blue-teamers curious about the offensive side, and seasoned players after a session of sharp problems. Come solo or bring your team.

Bring curiosity and persistence. Iron Forge brings the anvil.
