SECURITY TRAININGS

We offer the world’s first training WebAssembly security training in 4 to 5 days format. We have also developed an exclusive security training about Rust that required only 2 days. Recently we also publish a new online course about C/C++ WhiteBox fuzzing. Customization is possible but need to be requested as soon as possible.

Choose your favorite learning format!

  • Live ONSITE training

    Training will be given onsite at your office allowing direct and physical interaction with the attendees. (Currently not available due to COVID)

  • Live ONLINE training

    Security training will be given online during live Zoom or Google meet sessions allowing direct and real-time interaction with the attendees.

  • Offline RECORDED training

    Videos on demand (VoD) of the training will be accessible on a dedicated platform allowing participants to follow at their own pace and at any time corresponding to their schedule.

  • Mixed format

    This format is basically a mixed of the live online training and the offline VoDs format. Attendees will get access to the video recording and after some time (like one month), some live Q&A session will be defined.

Rust Security Audit and Fuzzing

This goal of this course is to give you all the prerequisites to understand which kind of vulnerability can be found inside Rust code. You will learn how to find low hanging fruits bugs manually and automatically using Rust auditing tools. Finally, you will discover how to build custom Rust fuzzers, triage/debug crashes and improve your code coverage using differents techniques.

Along this training, students will deal with a lots of hands-on exercises allowing them to internalize concepts and techniques taught in class.

Practical Web Browser Fuzzing

Web Browsers are one of the most used and critical software in the world. Using millions of lines of code, they are in charge of handling, sanitizing, and interpreting all kinds of (untrusted) data coming from the web. To be honest, It’s just impossible for developers to write such complex pieces of software (involving compilers, interpreters, and parsing libraries) without introducing any bugs.

As shown in the last years, Fuzz testing is by far the most efficient and scalable testing technique to find software bugs. In this training, we will apply fuzzing to find critical vulnerabilities in different web browser implementations.

First, this course will give you all the prerequisites to understand the architecture and major components of modern web browsers. Then, you will create and set up a testing environment allowing you to easily replay, debug, minimize and analyze existing issues, CVEs, and PoCs. Over dedicated modules, you will discover and fuzz the main browser components such as DOM, JS engines, JIT compilers, WebAssembly, IPC. You will learn how to use famous tools (Domato, Dharma, Fuzzilli, Frida) and create your custom fuzzers to apply different fuzzing techniques (coverage-guided, grammar-based, in-process fuzzing) to find vulnerabilities/bugs.

A lot of hands-on exercises will allow you to internalize concepts and techniques taught in class. This course will mainly focus on Google Chrome, Firefox, and WebKit/JSC.
