Updates

Announcement #1

We are aware that all local Polytechnics will be holding their Graduation Ceremony in May 2016, and after internal discussions, we've agreed that Polytechnic students whom are graduating in the year of 2016 shall be allowed to participate in the X-CTF finals. We apologize for the change in the regulations.

Announcement #2

Dear All Participants,

Thank you so much for participating in the X-CTF Online Qualifiers held from 9 April 2016 to 10 April 2016. Everyone has done extremely well and we are grateful that you have devoted your time over the weekend.

The following institutions have no representative:
1) Republic Polytechnic (RP)
2) Singapore Institute of Technology (SIT)
3) Singapore Institute of Management (SIM)

As there are no teams representing the aforementioned institutions, their slots have automatically been forfeited. Thus, we have decided to increase the limit of teams per school to 3 but maintain the 22 slots pre-allocated for the Finals.

The competition will be held for a duration of eight hours and each team will be given a set of challenges to solve in order to retrieve a "flag".
