CTF Team
About the Team
Established in September 2025, C2L4B is the Capture The Flag (CTF) team of the Cybersecurity Laboratory (CS-Lab).
We operate with a dual mindset: education and competition. Our primary goal is to complement our academic path (B.Sc., M.Sc. and PhD) by exploring practical domains and techniques that go beyond the traditional curriculum. We use CTFs as a hands-on method to deepen our understanding of security concepts.
Our team is composed of students and Alumni working side-by-side. This collaboration allows us to share knowledge across different levels of experience, creating an environment where everyone, from newcomers to graduates—teaches and learns from one another.
Weekly Sessions
We gather every week to solve challenges and share knowledge.
Currently, our meetings take place at E5.6@DEI on Wednesdays at 16:00.
(Time may vary slightly from week to week).
