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. Hands-on: compiling programs to WebAssembly. Introduction to Wasabi.

D Lehmann, M Pradel. Proceedings of the Twenty-Fourth International Conference on Keywords and phrases WebAssembly, program logic, separation logic, soundness, Wasabi [23] is a general purpose framework for dynamic analysis. WebAssembly Binary Toolkit (WABT): wat2wasm / wasm2wat for converting Wasm binaries to/from text, wasm-objdump for inspecting binaries, and wasm- interp Sep 16, 2019 WebAssembly (Wasm) a été proposé comme alternatif de bas niveau, programs, and it is currently also offered by other libraries.

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).

The approach is based on binary instrumentation, which inserts calls to analysis functions written in JavaScript into a WebAssembly binary. 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.

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 (by Daniel Lehmann) is a very cool instrumentation and analysis tool for WASM >However, it does not exactly ﬁt our needs >Wasabi is written in Rust and intended to be run from the terminal >Wasabi does its analysis by injecting Javascript >If we want to run a game at any decent FPS, we need to call Javascript as infrequently as possible Current state of WebAssembly debugging and tracing sets limits in browser on number of lines disassembled during debugging in development tools on both Firefox and Google Chrome based browsers.

One distinctive feature of WebAssembly, which is relevant for Wasabi, is how control-flow is encoded. 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.

One distinctive feature of WebAssembly, which is relevant for Wasabi, is how control-flow is encoded.

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.

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. 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.
