Participation in CTF (Capture The Flag) Contests

I'm a member of 'urandom' (from SECCON 2012 Final). I participate in SECCON CTF contests, but I'm just like a paperweight...

Operation of CTF Contests

I'm an initial member of tkbctf operation team. Mainly I am in charge of development/maintenance of a score server (earth/parasol). (Note that tkbctf is an unofficial contest, so there is no relationship with the university authorities.)

  • tkbctf1 (on May 4th - 5th, 2013) in charge of developing a score server (earth), making a challenge: Diva
  • tkbctf2 (on September 29th, 2013) in charge of developing a score server, making a challenge: SkillAnalyzer
