WebAssembly is a new standard that allows assembly-like code to run in browsers at near-native speed. But how does WebAssembly work, and how does it execute code while maintaining the security guarantees of a browser? This presentation gives an overview of the features of WebAssembly, as well as examples of vulnerabilities that occur in each feature. It will also discuss the future of WebAssembly, and emerging areas of security concern. Learn to find bugs in one of the newest and fastest growing parts of the browser!
