PicoCTF

PicoCTF is a cybersecurity competition, primarily targeting middle and high school students, but open to anyone with an interest in learning about cybersecurity. Created by experts at Carnegie Mellon University, PicoCTF focuses on teaching foundational cybersecurity concepts through a series of captivating, interactive challenges.

The competition is designed as a Capture the Flag (CTF) event, where participants work on a variety of cybersecurity tasks to find hidden flags, which they then submit for points. These tasks encompass a broad range of topics, such as cryptography, web exploitation, forensics, reverse engineering, and binary exploitation. As participants advance through the challenges, they are exposed to more complex concepts, enabling them to hone their cybersecurity skills.

PicoCTF is typically held annually, and participants can compete individually or in teams. All past competitions are freely accessible on the PicoCTF website, offering a valuable resource for learning and practice. This competition provides a fun and engaging way for students and enthusiasts to explore cybersecurity, while promoting interest in the field and fostering the development of future cybersecurity professionals.
