 We've created a small guide to get you started with CTF and more or less infosec in general. There are a few selected resources for each of the major CTF disciplines that should help you get up to speed in those.

 During 9447 CTF 2014, [europe]({{ site.url }}/files/9447ctf2014/europe) was a series of 3 exploitation challenges, all using the same binary. Each one would yield a different flag and in total those three flags where worth 700 points (200, 120, 380).
