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/. 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.

WASM 101 >WebAssembly "deﬁnes an instruction set and binary format for an assembly-like architecture" >WebAssembly is built to be targetable by existing compilers and languages >Finally we can write web applications in C! There is growing interest in using WebAssembly as the Virtual Machine for Ethereum, allowing contracts to be programmed in a great many (more conventional) languages. Wasabi - a framework for dynamic analysis of WebAssembly Wasabi is an HTTP framework "for dynamic analysis of WebAssembly programs". However, now Wasabi has now merged with Ktor. What is Ktor? 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. Subscribe FlareOn 2018 Level 5 - Solving WebAssembly Crackme (Part II - Wasabi) 16 Sep 2018 on reverse . Level 5 of FlareOn 2018 was a WebAssembly crackme challenge where we were handed a compiled wasm file and told to extract the password.

Dynamic analysis means observing some properties of a program while it is running.Dynamic analysis is routinely used to find and fix bugs, identify performance bottlenecks, or to search for security problems. 2018-08-31 Usage Tutorial Create WebAssembly programs Manually: ;; paste into hello-manual.wat (module (import "host" "print" (func $i (param Manually: From C with Emscripten: Apply Wasabi to WebAssembly programs in the browser Step 1: Instrument # start with C to Wasm (via Emscripten) project Step 1: WebAssembly execution is a stack machine with per-function locals, similar to the JVM (Lindholm et al., 2013).

News.

WebAssembly execution is a stack machine with per-function locals, similar to the JVM (Lindholm et al., 2013). 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. It is based on binary instrumentation, which inserts calls to analysis functions written in JavaScript into a WebAssembly binary.

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 . Task 0.3: Compiling C to WebAssembly Goals Learn about Emscripten Compile C code to WebAssembly + HTML harness with Emscripten See that you can “run C code in the browser” Injects metering into webassembly binaries. This counts computation time for a given program in units of gas (and allows limiting it).

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 … Wasabi is an HTTP framework "for dynamic analysis of WebAssembly programs".

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, …). Real time collaborative diagramming for teams In this talk, I briefly introduce WebAssembly concepts , Ewasm specificity and as some open-source tools that make you the life easier (Octopus, Wasabi, …).
