WebAssembly Security
"From Reversing to Vulnerability Research"

This courses will give you all the prerequisites to understand what’s a WebAssembly module and its associated virtual machine. At the end of this intensive 4 days, you will be able to reverse statically and dynamically a WebAssembly module, analyze its behavior, create detection rule and search for vulnerabilities and security issues. You will learn which security measures are implemented by the WebAssembly VM to validate and handle exceptions. Finally, you will discover how to find vulnerabilities inside WebAssembly VMs (Web-browsers, Standalone VM) using differents fuzzing techniques.

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

Rust Security
"For Hacker and Developers"

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.
