The Cyber Security Competition

Competition

What is Major League Security?

Switzerland's cybersecurity competition for university students. Pick a real security problem, propose a solution or expose a flaw, and pitch it to experts from ETH Zurich and Zürcher Kantonalbank.

This is not a CTF.

You pick the problem.

No flags to chase, no artificial puzzles. Instead, you can be creative: propose a new protocol, a new system, or find what's broken in existing technology, fix it, and explain why anyone should care.

An expert audience.

Your submission gets reviewed by researchers at ETH Zurich and engineers at Zürcher Kantonalbank: people who deal with security and availability challenges day to day.

Three tracks to choose from.

Pick whichever one you'd actually want to work on: Networking & SCION · Identity & E-ID · Fintech Security.
