What it CTF?

CTF, or Capture The Flag, is a type of cybersecurity competition where participants solve challenges to find “flags” (specific pieces of text) hidden within systems, files, or code. These challenges test skills in areas like cryptography, web security, reverse engineering, forensics, and more. CTFs are popular in the cybersecurity community and are used for learning, practice, and fun.

Types of CTFs

1. Jeopardy-Style

   • Participants solve challenges organized into categories (e.g., cryptography, forensics, etc.).
   • Each solved challenge reveals a flag, earning points.
   • Examples: Decoding encrypted messages, analyzing memory dumps, or identifying vulnerabilities.

2. Attack-Defense
