Capture the flag (cybersecurity)

Capture the Flag (CTF) in cybersecurity is a type of competition that challenges participants to solve security-related puzzles and problems to capture “flags”—usually strings of text that represent successful exploitation of vulnerabilities or successful completion of a task. CTFs are designed to educate and test the skills of participants in various areas of cybersecurity, including: 1. **Web Security**: Finding and exploiting vulnerabilities in web applications. 2. **Cryptography**: Breaking codes or deciphering encrypted messages.
