- 3. What are your areas of interest where the WebAssembly(WASM) is used? Cloud-based microservices (AWS, Azure, …) Web-based 3D (Unity, Unreal Engine, WebGL, …) Code trust (Cloud security, Document security, Malware response) Web based video processing/AI (FFmpeg, mediapipe, Radiology(Medical), …) Blockchain (Smart contract, eWASM, …) No response Other
- 4. Choose a WASM development tool or runtime that you've used or heard of. No response Other
- 5. What do you think are the difficulties in introducing the WebAssembly(WASM)? The awareness is low. The learning curve is too high. I don't know what it's used for. No active communities. No response Other

- 34. Can WASM support techs like JNI? • Although not completely the same • You can consider using a WASI socket • Or expanding a separate module with a dynamic link(*.so, *.dll) in the runtime itself. • If you need this, I recommend you to look into WAMR (WebAsssembly Micro Runtime) • https://github.com/bytecodealliance/wasm-micro-runtime
- 35. JVM LLVM WASM First appeared May 1995 May 2003 March 2017 Type of code Bytecode Bytecode Bytecode Size of runtime >130MB (Oracle JRE 7) N/A (Because this is a compiler for native system) <19MB (Wasmtime 3.0.1) Size of popular packages Very big (e.g. java.*, JWT, Spring, Android, …) N/A Small (e.g. libraries from C/C++) Size of the target application Big Almost small Small Allow to system access by default? Yes. No additional security processes such as file I/O, or connect network. Almost yes No. A code is strictly isolated in runtime. If you need escape must use WASI. Where is it usually deployed? Smartphone, TV, Desktop, … All targets of source code Web browser or web-based engine JVM, LLVM, WASM?
- 36. So, What is ASMNEXT interested in? • Office Automation and endpoint security • In South Korea, a ransomware delivery attack using the macro function of MS office and Korean Word Processor(HWP) has caused many victims, drawing attention as a big issue. • The ASMNEXT is working on ways to reduce this threat using the code isolation of WASM runtime. • Binary pattern matching on WASM • Using a library such as YARA (https://github.com/VirusTotal/yara) • WASM on PHP backend • PHP-based applications are often used with traditional word processors. I am looking for a successful way for both different applications to share the same logic. For example, Wordpress
