Capture the flag (CTF) in cybersecurity is a popular and engaging type of competition where participants, often referred to as “ethical hackers” or “cybersecurity enthusiasts,” attempt to solve various challenges to obtain flags. These flags are digital artifacts, usually strings of text or files, strategically placed within vulnerable systems or applications.

A CTF event’s challenges range from cryptography puzzles to reverse engineering tasks, web exploitation, binary exploitation, forensics, and more. Participants use their programming, network analysis, and system administration skills to uncover vulnerabilities, exploit them, and retrieve flags.

CTF events serve multiple purposes. They provide a platform for participants to hone their skills in a competitive environment, learn new techniques, and stay updated on the latest cybersecurity trends. In addition, they can help organizations identify and recruit talent by observing participants’ problem-solving abilities and technical prowess. Overall, they are a fun and effective way to develop and showcase cybersecurity skills.
