Igor Sikorsky Kyiv Polytechnic Institute invites pupils, students, and everyone interested in cybersecurity to take part in the 24-hour online competition Sikorsky CTF 2026.

After a successful debut in 2023, the competition returns in the classic Jeopardy format. Our main goal is to create an open arena where theory meets the practice of the real industry.

About the challenges and the tournament philosophy

This year’s pool of challenges will cover a broad range of cybersecurity domains: from basic reverse engineering and web vulnerabilities to forensics, cryptography, and related applied areas.

We position Sikorsky CTF not only as a challenge for experienced players, but also as an entry point for newcomers. The challenge architecture is built so that every participant can not only demonstrate their strengths, but also try themselves in completely new areas they have not yet encountered in class or in self-study.

Participation in the tournament is free.
