by Mad H@tters 🇺🇸 United States

Every year, the GreyHat cybersecurity club hosts an educational capture-the-flag competition to help college students around the world build cybersecurity skills. The competition features a number of intentionally vulnerable websites, insecure cryptographic schemes, exploitable binaries, and more. The full competition runs online from April 17 to April 18 and is open to everyone (college students, high school students, and security enthusiasts). We’ll have problems that are interesting to both beginners and advanced students.

The competition is open to all! More information will be provided on our Discord, at https://discord.gg/gjnP2uqYfd.

Real time: 16:00 UTC, not 4:00 UTC
