Unlike in the JVM or native code, instructions are structured into well-nested, implicitly labeled blocks. This paper presents Wasabi, the first general-purpose framework for dynamically analyzing WebAssembly. Wasabi provides an easy-to-use, high-level API that supports heavyweight dynamic analyses. It is based on binary instrumentation, which inserts calls to analysis functions written in JavaScript into a WebAssembly binary.

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 addresses several unique challenges not present for other 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.

Secondly, I will expose different techniques (Static/Dynamic analysis) and tools (Octopus, Wasabi, …) to perform a WebAssembly module analysis. Finally, we will hands-on with basic examples (crackmes) and go throws some real-life cryptominer and web-browsers plugins using WebAssembly module. Along the talk, I will only used open source tools Level 5 of FlareOn 2018 was a WebAssembly crackme challenge where we were handed a compiled wasm file and told to extract the password. Here we will look into two different ways of solving this challenge: ReCompilation to x86 (this blog post) and using a new dynamic-analysis framework called Wasabi (next blog post).

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. We talk about all things WebAssembly and WASI related and then dive into some code to try to get networking working in WASI-land The WebAssembly System Interface. WASI is a modular system interface for WebAssembly. As described in the initial announcement, it’s focused on security and portability. WASI is being standardized in a subgroup of the WebAssembly CG. Discussions happen in GitHub issues, pull requests, and bi-weekly Zoom meetings. 2019/10/22 @ Hack.lu 2019 In this workshop, I will first introduce WebAssembly concepts and why it’s consider as a “game changer for the web”. 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, …).

Wasabi is an HTTP framework "for dynamic analysis of WebAssembly programs". However, now Wasabi has now merged with Ktor. What is Ktor?

The following tutorials will be co-located with PLDI: (SafeAsync) Safe Asynchronous Programming: Methodology, Language, and Tools (DAWW) Dynamically Analyzing WebAssembly with Wasabi (V8) Using V8 as a Research Platform (DPAQL) Declarative Program Analysis with QL (PPET) Probabilistic Programming using Edward/TensorFlow (DRLT) Deep Reinforcement Learning using TensorFlow 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.
