LyonCTF Information

Spanning from February 18th at noon to February 21st at noon, we are excited to announce the inaugural LyonCTF cybersecurity competition!

In this capture the flag (CTF) contest, teams of middle and high school students aged 13+ across Ontario will battle it out with their skills in digital forensics, website and application exploitation, reverse engineering, and cryptography! Intended for students of all experience types, the challenges are designed with a low barrier of entry to enable even first-time competitors to gain experience and knowledge in an enjoyable, cooperative way.

This contest is organized by the Mackenzie Computer Programming Team and $300 worth of prizes are generously sponsored by the Educational Computing Organization of Ontario. The contest organizer team can be found here.
