A cybersecurity competition for high schoolers.

FAQ

What is a CTF?

A CTF, or Capture the Flag, is an online cybersecurity competition where players work in teams to solve as many challenges as possible. Challenges are services or files that you must investigate and exploit in order to obtain a string called the “flag”, which is submitted for points.

Who are you?

ångstromCTF is run by a team of students from Montgomery Blair High School. Now in our 5th year, we are one of the largest high school-oriented CTFs, with over 1,300 competing teams in 2019. To see who helped out with each competition, check the individual competition sites.

What if I've never done anything like this before?

Then ångstromCTF is a great place to start! Our challenges are meant to guide students and help them develop their skills, even if they start off as a complete beginner. To get an idea for what the challenges will be like, be sure to try out the challenges from previous years.

I'm not a high schooler. Can I still compete?

Yup! You'll simply need to mark yourself as ineligible for prizes when signing up. Ineligible players will still be able to view challenges, submit flags, and see how they rank compared to other teams.
