Jul 16, 2020 2019, Wasabi: A Framework for Dynamically Analyzing WebAssembly. 2019, CheriABI: Enforcing Valid Pointer Provenance and Minimizing
erything from PDF tools [15] to game engines [16] are using WebAssembly to create programs that were previously too demanding to run reliably on the web. A major focus of WebAssembly is faster performance which means good tools for analyzing and tuning the execution of WebAssembly programs are vital to the development of more applications.
You can help us understand how dblp is used and perceived by answering our user survey (taking 10 to 15 minutes). Currently, I work on WebAssembly binary security; for example, how memory vulnerabilities in source languages such as C make compiled WebAssembly binaries exploitable (USENIX Security 2020). I am also the main author of Wasabi , a dynamic analysis framework for WebAssembly (ASPLOS 2019, best paper award), for which I developed a WebAssembly binary parser and instrumentation library . Wasabi | home, repo "WebAssembly analysis using binary instrumentation", a dynamic analysis framework. wasmsign | repo A tool to add and verify digital signatures to/from WASM binaries. Source-level debugging. Chrome DevTools | article.
Why: Developers are starting to push WebAssembly beyond the browser, because it provides a fast, scalable, secure way to run the same code across all machines. Earlier this year, we announced WASI, the WebAssembly system interface. With this system interface, WebAssembly can be used outside the browser in a portable Wasabi - a framework for dynamic analysis of WebAssembly. SOFTWARE-LABS.ORG. Wasabi is an interesting little framework that takes a wasm binary and injects instrumentation code, allowing profiling of function calls.
Once built, you can use the container via (assuming you have a hello.wasm file in your working directory) ls > hello.wasm docker run --rm-t-v ` pwd `:/data wasabi /data/hello.wasm /data Usage Tutorial. Create WebAssembly programs. Manually: Please also check out our website at http://wasabi.software-lab.org.

It is based on binary instrumentation, which inserts calls to analysis functions written in JavaScript into a WebAssembly binary. Wasabi provides an easy-to-use, high-level API that allows implementing heavyweight dynamic analyses that can mon-itor all low-level behavior. The approach is based on binary instrumentation, which inserts calls to analysis functions written in JavaScript into a WebAssembly binary. Wasabi addresses several unique challenges not present for other

Secondly, I will expose how to analyze a WebAssembly module using different techniques (static & dynamic) as well as some open-source tools that make you the life easier (Octopus, Wasabi, …).
