About me
Welcome to my little corner, I am Jonathan Salwan and I am a MSc student at Paris. During my free time, I enjoy doing things in various fields like: OSdev, Linux Kernel, static and dynamic analysis, bugs hunting, bugs exploitation and other low-level stuff. You will find the results of my different researches on this blog.
