"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.
