About me
Curious by nature and thirsty for knowledge, I'm passionate about many subjects. My attention has been drawn to many subjects including algorithms, mathematics, education, computer science and above all: cybersecurity. For almost 7 years now, I've been trying to learn more and more about the way our information systems are organized. Breaking down each layer one by one to understand its essentials and be able to manipulate its workings. This obviously led me to delve into offensive security, since its essence resides right here: hijacking the way things work.
I'm currently working on a freelance basis with various customers to ensure the security of their information systems and develop their arsenal of automated tools. My services range from penetration testing to test the security of IT systems, to the development of automation tools, audit modules and scripts of all kinds.
In addition to the missions I'm given, I'm constantly learning about the new attack techniques emerging and the new technologies in use around the world, as these are the focus of tomorrow's attacks.
What i'm doing
-
Application development / scripting
Development of optimization and automation software. Projects vary according to demand: automatic document generation, scripting, auditing software or modules, vulnerability exploitation scripts. I master many programming languages: Python, C, C++, Java, bash, web...
-
Internal system penetration testing
Since it's an internal system, there's no need for protection... oh wait? This is surely one of the most interesting parts of the penetration test, as the attack vectors are diverse and surprising.
-
Web application penetration testing
Breaking into web applications is one of my favorite hobbies, an activity I would recommend to anyone lacking dopamine. On a more serious note, this is surely the most important part of a penetration test, as web services are often exposed to the public and thus become entry points for attackers.

Education
There's something pure and beautiful about teaching. We're where we are because others have been willing to share their knowledge, so it seems healthy and natural to do the same for others who haven't been given the chance. Teaching mathematics and sharing knowledge about offensive security remain key activities of mine.
Mission proposals
You can contact me directly on this email baptiste.coste@proton.me .
I can also be joined on two freelance applications : malt and upwork.
If you wish to see some examples of my work, I encourage you to check this Security Audit Report. It contains the final report of a Vulenrability Assessment on a REST API in production. It is, for obvious reasons, anonymized.
If you have a project on training or formation related to the Cybersecurity field, do not hesitate to contact me, I am really open to this kind of proposal.
