Capture The Flag
hacking environment

Ready to hack?

Capture The Flag (CTF) competitions challenge you to solve problems and earn flags.

To solve a challenge, you need to hack your way to the flag.

Most competitions are only online for a few days. The 247CTF is a continuous learning environment.

Learn by doing!

Challenges are directly accessible from the platform; no VPN or setup required.

Rather than sharing, you control your own challenges - start, stop and restart at any time.

New challenges are added monthly, to enable you to continuously learn, hack and improve.
