The file is the module exactly as the page had it. WebAssembly does nothing on its own: it runs only when a script instantiates it. Labels describe what the module contains and are leads, not verdicts.
At a glance
- What it is
- Not identified. Its build does not name it and it matches no library we know.
- Names it came with
- From storage.googleapis.com. Its build and the addresses it came from say so; whoever builds a module chooses these, so they are hints.
- How it was built
- Compiled with Emscripten, usually from C or C++.
- What it can do
- None of its imports reaches the network, runs code or changes the page. Judged from the names of its imports.
- Where we saw it
- On 3 public scans, 2026-10-17 to 2026-10-28.

How it was built
Compiled with Emscripten, usually from C or C++.
- Language
- C or C++, probablyNot named. Emscripten and clang mostly compile C and C++.
- Compiler
- EmscriptenThe toolchain that compiles C and C++ (sometimes Rust) for the web. It comes with the JavaScript that loads the module.
Read from text inside the module (its build metadata and paths the compiler left) and from its import and export names. Whoever builds a module can change or remove these, so treat them as hints. They say how a module was made, not what it does.
Decompiled code
257 of 257 functions decompiled to C-like pseudocode; 29 more are imported from the page.
Decompiled code is a reconstruction from the file, so names and types are often guesses. Query values in URLs are masked here; the downloaded file is unchanged.

Text it passes to the page
Fixed text the module hands to the page's JavaScript when it calls an import, read from the module file. Imports that reach the network, run code or change the page come first; web addresses are shown as their host.
