Capture the Flag.

Why break things.

I compete regularly in CTF competitions. Breaking systems is the fastest way to understand how they actually work, and how to build ones that don't break the same way.

Areas of practice.

• Network security: traffic analysis, protocol quirks, misconfigured services.
• Cryptography: broken implementations, weak parameters, side channels.
• Reverse engineering: taking binaries apart to see what they really do.
• Web vulnerabilities: the classics, plus the ways modern stacks reinvent them.

One hint.

The terminal on the front page hides a flag. If you find it, you already know what to do with it.
