Choose your path

Each path is a structured sequence - no jumping around, no gaps. Start with the fundamentals, then specialize. Every lesson ends with hands-on practice and a real breach to show why it matters.

Easy

Security Fundamentals

The bedrock. Skip this and you'll plateau.

Master the terminal and the network - the two foundations every other security skill is built on. This is where every aspiring hacker should start.

2 modules 17 lessons
Medium

Web Application Security

Where most bug bounties are won.

The OWASP Top 10 and beyond - SQLi, XSS, SSRF, IDOR, auth flaws and more. Hands-on with Burp Suite against deliberately vulnerable apps, each mapped to a real disclosed report.

1 modules 12 lessons
Hard

Offensive Security & Pentesting

Recon → exploit → escalate → report.

Full kill-chain methodology: enumeration, exploitation, post-exploitation, pivoting, and professional reporting. Builds toward OSCP-style boxes.
