About C2C CTF 2023

The INCS-CoE has a five-year plan to hold an international Capture The Flag (CTF) event for students at the member universities, titled the Country-to-Country CTF (C2C CTF), starting in 2020. In 2023, Keio University will host the C2C CTF, which will be the first C2C CTF to be held in an in-person format, taking into account the social situation caused by the COVID-19 infection
