What is redpwnCTF?

redpwnCTF is a cybersecurity competition hosted by the redpwn CTF team. It’s online, jeopardy-style, and includes a wide variety of computer science and cybersecurity challenges. Compete in challenge categories such as binary exploitation, reverse engineering, cryptography, and web to earn points. Please join our Discord to learn more and get notified as the competition date nears!

What if I’m new?

Don’t worry, we’ve intentionally written multiple challenges in every category geared toward participants with little or no programming experience. We understand it can be scary trying something new, but we hope redpwnCTF will give you a gentle introduction into the wonderful world of cybersecurity!

You can also check out our challenges from previous years on GitHub:
