binja

binja is a Japanese team organized originally in order to reach DEFCON 2014 Finals.Until then, sutegoma2 was the representative CTF team in Japan. But surprisingly they failed in Quals and the last chance to be qualified was SECUINSIDE 2014. So the top three teams sutegoma2, EpsilonDelta, and katagaitai formed binja and thus here we are. Now our team consists of really a lot of Japanese teams like sutegoma2, EpsilonDelta, katagaitai, 0x0, scryptos, dodododo. But actually, always on average only 10 of us participate in CTF somehow
