Nicolas Bourras

Hi! I’m Nicolas Bourras, aka vivescere - a french (junior) pentester working at Orange Cyberdefense.

I love cycling, programming, photography and more recently I started getting into cooking as well. I’m also vegan.

I mainly program in Rust these days, but I also regularly use Dart (with flutter) and python. I have experimented with a fairly large number of languages, and love learning new ones.

You can find me online :

What I’ve been working on⌗

This section is a bit empty for now - I’ve done a lot of projets that aren’t good enough to be here.

CTF - Cyber Threat Force⌗

I also wrote an article on this CTF, which you can read here. My team ranked fourth, and I ranked sixth!

CTF - DG’hAck⌗

I wrote an article on this CTF, which you can read here. It’s complete with writeups for 14 challenges, out of the 16 I’ve completed.

I ranked first out of all the students ; there was only 3 challenges that I didn’t manage to solve, I still need to get better at reverse engineering / binary exploitation!

CTF - DGSE - Brigitte Friang⌗

My first CTF! I ranked 61 ouf of 785 teams, while being alone. It was a great learning experience.

Introduction to Flutter⌗

This series of videos (in french) was an attempt at teaching Flutter, a framework made by Google which is used to create mobile applications. Unfortunately, it didn’t go very far because I started working on some other projects.

Beacon (2016)⌗

NOTE: the application was taken offline for a while, because I have to update it so that it remains compliant with the Play Store policy.

This application allows an athlete (or anyone who wants to, really) to share their location in realtime.
