Crackmes.one Reverse Engineering CTF 2026
A week-long CTF dedicated exclusively to reverse engineering.
Hosted by crackmes.one, inspired by the legendary Flare-On Challenge.
Time
Start: Sat 14 Febuary 2026 00:00:00 UTC
End: Sat 21 Febuary 2026 00:00:00 UTC
(Duration: one week)
Format
- Team-based, unlimited team size
- All challenges unlocked from the start
- Reverse engineering only — no pwn, no web, no crypto
Motivation
Most jeopardy-style CTFs mix categories: RE, pwn, web, crypto, misc, etc.
That’s like a triathlon — one person is usually only good at one category.
But for RE fans, RE-only CTFs are rare.
We want to change that:
- Play it with your friends as a team
- All challenges unlocked → no blockers if you get stuck
- One week duration → longer than weekend CTFs, but not as exhausting as Flare-On
Challenges
- Exclusively reverse engineering
- A wide range of platforms, architectures, and styles
- Carefully designed to be diverse and enjoyable
