Save the date! March 17 to 21, take your chance with the GitHub CTF “A Call to Hacktion!”
What is a CTF? In software security, a Capture the Flag (CTF) is a contest where participants conduct real-world attacks on a given target to find and exploit a security vulnerability. When the exploit is successful, they can get their hands on a “flag.”
Are you an action hero? If you use and like GitHub Actions, this CTF is the opportunity to challenge your knowledge and your workflow writing skills. It’s also the opportunity to learn about the nitty gritty of workflow security considerations! This contest is a solo activity, and you only need your GitHub Actions skills to participate.
Follow @ghsecuritylab on Twitter, or keep your eyes on our CTF page for additional details.
Mark the date on your calendar: March 17!
