The International Cyber Security Center of Excellence and Northeastern University invite students to participate in the 6th International Country-to-Country (C2C) Capture the Flag (CTF) competition, C2C-CTF. This exciting competition allows students to work together as international teams to solve interesting CTF challenges while learning new skills, socializing, and promoting international collaboration and friendship. 

C2C-CTF 2025 is organized and hosted by Northeastern University and will take place in person on its campus in Boston, Massachusetts. The organizing committee invites students at all levels from universities in the UK, USA, Japan, Israel, EU, and Australia to apply to participate.

Students can register online and participate individually in an online qualifying event from February 7 to 9, 2025. Students who qualify for the final competition will be organized into teams of five members from different universities to encourage international academic collaboration. These teams will compete in person at the final event in Boston from July 7 to 9, 2025. 

The organizers will hold webinars as part of the competition and educational process, during which students will learn about and discuss cybersecurity issues. 

A goal is to create diverse teams for the competition by selecting competitors from a broad range of backgrounds, nationalities, languages, genders, experiences, and cybersecurity skills. We seek motivated and resourceful participants who enjoy a tough, intellectual challenge in a cooperative international context -- we are not merely looking for experts who have won other hacking competitions, although those students are also welcome and strongly encouraged to participate. 

Interested students should apply here by February 1, 2025.
