Howdy! Ready to tackle challenges in hacking, forensics, cryptography, and coding? These topics will help you learn about the digital dangers lurking on the internet. While playing, you’ll discover how everything you post online stays there forever (yes, even that comment you regret on YouTube), or how a hacker could access your account if your password is simply the name of your favorite football team.

Ready to jump in? Click on a challenge title to begin. Each challenge page provides instructions on how to find the flag. Think of it like when astronauts first landed on the moon—they planted a flag to mark their success. Similarly, in Capture the Flag (CTF), you're searching for "digital flags" formatted like this: flag{text}. Find that after completing a challenge, and you've solved it! Enter the flag in the input field under the challenge title to score points, ranging from 20 to 75, and watch your ranking rise on the scoreboard, alongside your classmates.

Teachers can request a class code by filling out this form. With the CTF code, your students can register for the challenges, and only their scores will be shown on the class leaderboard. Plus, the teacher module gives access to student progress and challenge solutions.

Hackchallenges is a hobby project developed by ethical hacker Sanne Maasakkers (twitter or linkedin), to increase the security awareness of children and inspire them to choose a career in IT.
