Quarkslab is a French company specializing in information security R&D, consulting and software development. Our expertise is in combining offensive and defensive security to help organizations adopt a new security posture: Force the attackers, not the defender, to adapt constantly. Through our consulting services as well as our software we provide tailored solutions to organizations, helping them to protect their assets, sensitive data, and users against increasingly sophisticated attacks.
Quarkslab is an avid and active user of, and contributor to, Open Source Software and develops and maintains state-of-the-art security tools such as LIEF , QBDI, Triton, Irma, and several other projects.
We develop two commercial software products: QFlow, a platform to automate and orchestrate security analysis of files at scale, and QShield, advanced code and data protection software to disrupt code lifting, reverse engineering and tampering attacks.
Bluetooth Low Energy has been subject to a lot of research so far (such as the famous InternalBlue or SweynTooth attacks) but a few of them targeted some corner-cases of the specification that require high-level manipulation of the GATT layer.
The goal of the proposed internship is to implement a flexible and permissive Bluetooth Low
Energy stack compatible with our internal BLE tools and to perform some high-level fuzzing of multiple BLE stack implementations. Development/modification of an embedded firmware may also be required to fit the needs regarding this fuzzing approach.

How to Apply?
To apply for an internship position, you must be a student, able to communicate effectively technical matters in written and spoken English, and willing to present the results of your internship to a large group of curious Quarkslab colleagues.
To apply prepare the following elements:
Package these elements and send them via email to internship-AT-quarkslab-DOT-com, with the subject field containing the internship name mentioned in the respective offer. Alternatively, you can apply here with all the above attached.
Do not forget that the key aspect of a good application is to show what you have already achieved, related to the topic or not. So do not be shy and apply! We know that you can do it.
Each internship offer comes with a little assignment that should not require too much time to be completed. The result will show us not only the type of skills and knowledge you already possess, but also how ingenious you are and how well you can present your reasoning. It will serve as the basis for the interview you will have in the selection process. The assignment works both ways and is also intended to make sure that you like the topic as well as the technical aspects of the internship. If unsure about a specific aspect of a challenge, do not hesitate to drop us an email. We want to discuss not frustrate you!
The first applications usually reach us by November, and we start reviewing them right away. Every year, the filling is alike: half of the internships are filled by Christmas, while the others remain open until March.
Being an Intern at Quarkslab
We consider internships as opportunities to spot profiles that match how we work. They are intended to guide students to enter the professional world as potential future colleagues if they feel like it. We love interns because they bring fresh air to the company and because we see them grow, not only during the internship but also after, when they are hired and can get to work on so many other topics. There are two goals in every internship we offer:
Training and growing people in the security industry is part of the company's DNA. That is why we provide in-depth blogposts, tools, trainings, weekly internal conferences (called fridaycon, guess when they are), we teach in universities and schools, write articles in tech magazines and send our less experienced hires to a 6-month intensive training program (BADGE-RE or BADGE-SO). Sharing is caring, but sharing is also learning. We provide the environment for that the rest relies on you.
