2018-08-31 · Wasabi provides an easy-to-use, high-level API that allows implementing heavyweight dynamic analyses that can monitor all low-level behavior. The approach is based on binary instrumentation, which inserts calls to analysis functions written in JavaScript into a WebAssembly binary. docker build --rm-t wasabi . 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: WebAssembly is the new low-level language for the web and has now been implemented in all major browsers since over a year. To ensure the security, performance, and correctness of future web applications, there is a strong need for dynamic analysis tools for WebAssembly.

Wasabi: A Framework for Dynamically Analyzing WebAssembly [5] WebAssembly has many use cases such as audio/video processing, machine learning at the client-side or full 3d games. Wasabi statically instruments a WebAssembly binary, such as program.wasm, inserting instructions in the program’s original instructions. Bytecode is modified to be independent of the source code. Introduction to WebAssembly.

Dynamic analysis is routinely used to find and fix bugs, identify performance bottlenecks, or to search for security problems. We offered a tutorial on how to use Wasabi for dynamically analyzing WebAssembly at PLDI 2019. Although the conference is now over, all the material is online at http://wasabi.software-lab.org/tutorial-pldi2019/.

SOFTWARE-LABS.ORG. Wasabi is an interesting little framework that takes a wasm binary and injects instrumentation code, allowing profiling of function calls. And Finally … Apply Wasabi to a larger program, here: WebAssembly port of C game engine Write dynamic call graph analysis, which is often a building block for other analyses LEB128 ("Little Endian Base 128") is used, for example in DWARF debugging information (see Appenix 4 for C pseudo code) and in the WebAssembly binary format.

And Finally … 2018-09-16 Wasabi: a dynamic analysis framework for WebAssembly Wasabi is written in Rust and built on top of WABT greenwasm is a WebAssembly engine written in Rust, designed to mirror the standard’s specification as closely as possible. Today, we announce the start of a new standardization effort — WASI, the WebAssembly system interface. 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.

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, …).

Inspecting. WebAssembly Code Explorer | online tool A simple binary explorer with neat binary code highlighting. One of those questions is about the performance overhead of the WebAssembly <-> JavaScript interop. In Wasabi, we have a lot of this, because the "analysis hooks" are written in JavaScript and we insert roughly one hook call per original instruction into the wasm binary.
