PACTF 2017 Writeups

This is a collection of my writeups for the challenges I have completed in PACTF 2017. I am not a student studying infocomm security. I am just doing this as a hobby and a means to learn Python and Shell scripting. With this, please do not expect my solutions to be the most elegant. Feedback is greatly appreciated too.
