Choose your level:

Beginner

This level is perfect for you if you’re just starting out in the world of CTFs. Maybe you’ve dabbled with tools like Burp Suite or Wireshark, have some basic Linux knowledge, and are learning to identify common web vulnerabilities like XSS or SQL injection. You haven’t fully compromised a machine yet, but you're curious, motivated, and ready to dive in.

Intermediate

This track is made for those who’ve already explored the CTF world. You’ve completed challenges on platforms like picoCTF, Hack The Box or TryHackMe, feel comfortable using tools like Burp Suite and Metasploit, and regularly write or adapt scripts in Python or Bash. Linux is your playground, and you’ve already analyzed memory dumps, extracted PCAP data, or successfully compromised full machines. You’re here to level up even further.
