C2C Background

Global Capture-the-Flag

The Country-to-Country (C2C) CTF competition is a five-year plan of INCS-CoE to host cyber-security competitions in five different countries. C2C will extend past experiences and lessons learnt from the successful Cambridge2Cambridge.


C2C will be an exciting opportunity for students to work together as international teams to solve interesting CTF challenges, while learning new skills, socialising, and promoting international collaboration and friendship.

C2C 2020

The inaugural C2C 2020, and associated activities, will be hosted at Royal Holloway, University of London, Egham, UK, on Winter 2020 (TBC).


Students should be full-time enrolled in University courses at UG/PG/PhD level. Applications will be considered from universities invited by INCS-CoE, which are currently based in the UK, USA, Japan, Israel, France and Australia.

C2C 2020 Selection Criteria and Funding

The International C2C Committee will select 60 students from the received applications, with which we intend to create diverse teams for the competition. We aim to select competitors from a broad range of backgrounds, nationalities, languages, genders, experiences and cyber security skills. We seek motivated and resourceful participants who enjoy a tough intellectual challenge in a cooperative international context. We are not merely looking at experts who have won other hacking competitions before.

Selected students ("finalists") will be provided with up to three nights’ accommodation on Royal Holloway campus, food, and social events, and (if required) local transportation between Heathrow airport and the campus. Students are encouraged to first check with their own institutions and funding sources, that travel (flights/trains) to/from the event and any further cost would be covered, should their applications be successful.


Award certificates will be given to the best teams and members. Every finalist will receive a participation certificate.
