Every moment like this is a great reminder of just how many talented people our competition brings together. Last week was all about pleasant meetings and sending out the gifts.

To be clear from the start: every prize-winning team received a cash reward, personalized certificates, and commemorative award plaques. And on top of that — some seriously cool gadgets from our partners!

University league

We were able to meet the University league winners in person and congratulate them live:

• KNUIA (the team captain collected the prizes) won 3 Google Pixel 7a smartphones, as well as a CCWD certification from Hack Defender Academy (the team decided that Arsenii Podvalnyi will take it).
• KSE_CS_1 (collected by the captain and a team member) took home 2 Google Pixel 7a smartphones.
• LeetSh4dows (the team came in full) received 1 Google Pixel 7a smartphone.

Our sincere congratulations to the winners! It is incredibly inspiring to see such a strong level of skill and enthusiasm from our young people. Let’s keep growing this community together.

Thanks to our partners

And of course, this competition — and especially a prize fund like this — would not have been possible without the support of our reliable partners. Our huge thanks to:

• Hack Defender Academy, the USAID project “Cybersecurity of Critical Infrastructure of Ukraine”, MUR (The Art of Ukrainian Investigations), and OPT1M1ZE CORPORAT1ON — for the prizes provided and for motivating the participants.
• Anton Boiko (Microsoft MVP, RD) — for technical support.
• The National Security and Defense Council of Ukraine, the National Cybersecurity Coordination Center, and the Department of Counterintelligence Protection of State Interests in the Field of Information Security of the SBU — for their trust and comprehensive assistance.

The competition is over!

Our 24-hour cybersecurity marathon is behind us. 🚩

The results will be announced live — join the stream to be the first to learn the winners and celebrate together with the whole community.

Thank you to all the teams for taking part, to the organizers for their tireless work, and to our partners for their support. See you at the next Sikorsky CTF!

Another important message for participants!

We are glad to share a special video greeting from our guest, the Head of the SBU Cybersecurity Department, Volodymyr Karastelyov.

In his address, he stresses that cyberspace is now one of the key lines of defense for our state. Modern CTF competitions are not just a game, but a real training ground for preparing the elite of national security.

He emphasizes that it is on platforms like Sikorsky CTF that specialists are forged who will soon counter real APT groups, protect critical infrastructure, and investigate incidents on a national scale. If you want to understand how much your skills in OSINT, Forensics, Reverse, or Pwn matter right now, make sure to watch this speech.

Score flags today to help defend the country tomorrow! 🇺🇦💻

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.
