Project Description 📄​
This project aim to improve security and resilience of WebAssembly runtimes and parsers using fuzzing. This project will help developers to audit automatically wasm runtime engines and identify security issues/bugs. Multiple fuzzing techniques will be used to achieve this goal but mainly grammar-based fuzzing and differential fuzzing. Complete documentation and user-friendly APIs will be provide to help developers to integrate new WebAssembly runtimes quickly and without any fuzzing skills.

- Team's Experience:
Patrick is an Independent Security Researcher specialized in vulnerability research, fuzzing, reverse engineering and program analysis. He is teacher of two training respectively about WebAssembly Security and Rust Security.
Patrick found hundred of bugs in opensource projects mainly inside WebAssembly VMs and parsers. He is the author of Octopus, one of the first open-source security analysis tool supporting WebAssembly and multiple Blockchain smart contracts bytecode to help researchers perform closed-source analysis.
