About the CTF

A week-long CTF dedicated exclusively to reverse engineering.
Hosted by crackmes.one, inspired by the legendary Flare-On Challenge.

Time

Start: Sat 14 February 2026 00:00:00 UTC
End: Sat 21 February 2026 00:00:00 UTC
(Duration: one week)

Format

  • Individual player, no team
  • 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:

  • Individual player vibe, so you try your best on the challenges
  • 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

Prizes

  • Binary Ninja licenses (5 for top finishers, 1 for best binja write-up)
  • Winrar licenses (seriously)
  • Hall of Fame
