The Snyk Developer Challenge is an event that allows conference attendees to test their security skills by fixing vulnerabilities in open-source projects, with the goal of earning points on a leaderboard and potentially winning a prize. The challenge takes place over several conferences in 2022, including THAT Conference, KCDC, Developer Week Cloud, DevOpsWorld by Cloudbees, NodeConf, and All Things Open. To participate, attendees simply need to register with an email address and alias, submit their chosen open-source projects, and start fixing vulnerabilities, with the option to import up to 10 projects. The challenge is designed to be fun and engaging, with no data collected or stored, and features a virtual "capture the flag" workshop for those who want to learn more about solving capture the flag challenges.
