|    'pwnable.kr' is a non-commercial wargame site which provides various pwn challenges regarding system exploitation. the main purpose of pwnable.kr is 'fun'.    please consider each of the challenges as a game. But, if you want to just study pwn-related stuffs, check out the following video lectures. |

   there are flag   files corresponding to each challenges (similar to CTF), you need to read it and submit to pwnable.kr to get the corresponding point.
in order to read the flag file, you need some skills regarding programming, reverse-engineering, bug exploitation, system knowledge, cryptography.
each challenges have author's intended solution, however, there are a lot of unintended solutions as well :)
the challenges are divided into four categories. [Toddler's Bottle]  -  very easy challenges with simple mistakes. [Rookiss]  -  typical bug exploitation challenges for rookies. [Grotesque]  -  these challenges are grotesque-y. painful to solve it, but very tasty flag :) [Hacker's Secret]  -  intended solution for these challenges involves special techniques. |
