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. Usage Tutorial Create WebAssembly programs Manually: ;; paste into hello-manual.wat (module (import "host" "print" (func $i (param Apply Wasabi to WebAssembly programs in the browser Step 1: Instrument # start with C to Wasm (via Emscripten) project Step 1: Instrument # start with C to Wasm 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 2018-08-31 2018-08-31 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. 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.

To ensure the security, performance, and correctness of future web applications, there is a strong need for dynamic analysis tools for WebAssembly. Unfortunately, building such tools from scratch requires knowledge of low-level details of the language, and perhaps even 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.

Secondly, I will expose different techniques (Static/Dynamic analysis) and tools (Octopus, Wasabi, …) to perform a WebAssembly module analysis.

In particular, the slides are available here and the hands-on tasks are in this repo under tutorial/. Wasabi: A Framework for Dynamically Analyzing WebAssembly Daniel Lehmann, Michael Pradel WebAssembly is the new low-level language for the web and has now been implemented in all major browsers since over a year. We offered a tutorial on how to use Wasabi for dynamically analyzing WebAssembly at PLDI 2019.

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.

WebAssembly execution is a stack machine with per-function locals, similar to the JVM (Lindholm et al., 2013).

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. 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 Wasabi, which stands for “WebAssembly analysis using binary instrumentation,” is a dynamic analysis framework.

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 .

This counts computation time for a given program in units of gas (and allows limiting it).
