Christmas CTF Platform

What is this?

This is a CTF platform that I used for 2019 Christmas CTF. (you can see challenges, here)
It is implemented in pure PHP and designed with the MVC pattern.
I chosen Jeopardy style and dynamic scoring method.

(This platform is based on munsiwoo/simple-mvc-php)

Dynamic scoring calculation formula (min_point=100 / max_point=1000)

round(min_point+(max_point-min_point)/(1+(max(0,(solve_cnt)-1)/4.0467890)**3.84))

You can change the hash salt in /src/config/config.php
The account below is default account for testing.

Username	Password
admin	admin
test_captain	test_captain
test_member	test_member
