# Introduction

## About me

Currently learning about reverse engineering and web exploitation. Playing CTF with [SKSD](https://ctftime.org/team/211952), [idek](https://ctftime.org/team/157039), and [HCS](https://ctftime.org/team/70159) (university team) as **ryuk**/**kosong**. Before this blog was created, i wrote writeup separately. Below are some links to my past writeup: 

* [Github Repository](https://github.com/kos0ng/ctf-writeups)
* [Medium](http://kos0ng.medium.com/)
* [Github Gist](https://gist.github.com/kos0ng)

I also do some (little) research individually about security, if you are interested you can take a look on this [**space**](https://kos0ng.gitbook.io/notes).
