Solution of SSTIC 2016 challenge, in French

This repository contains the scripts and other resources I have used to solve the computer-security challenge of SSTIC 2016, available at http://communaute.sstic.org/ChallengeSSTIC2016

It also contains the files needed to generate the report I have written to describe my solution. The generated PDF file is available at http://static.sstic.org/challenge2016/solutions/solution_nicolas_iooss.pdf

I am used to write code and README files in English, so even if the report describing my solution is written in French, every other file would be written in English.
