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
Built from the Rust crate ezjww_wasm.
How it was built
Written in Rust. wasm-bindgen connects it to the page's JavaScript.
What it can do
None of its imports reaches the network, runs code or changes the page. Judged from the names of its imports.

How it was built

Written in Rust. wasm-bindgen connects it to the page's JavaScript.

Language
RustThe Rust compiler (rustc) left its name in the module.
Connects to JavaScript
wasm-bindgenRust's bridge to JavaScript. It writes glue code on both sides, so the module can call page functions such as fetch or the DOM, and the page can call the module.
Rewritten after compiling
walrusA library for rewriting compiled modules. wasm-bindgen runs it on every build, so it comes with wasm-bindgen and says nothing more about 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.

What it is made of

3 Rust crates from crates.io, with the versions it was built with:

Build tools and versions it names:

  • Rust
  • rustc 1.98.1 (48a229cea 2026-09-01)
  • walrus 0.26.2
  • wasm-bindgen 0.2.122 (ddd322514)

Read from text the build left in the module: source paths, build metadata and .NET metadata. Whoever builds a module can change or remove it, so treat it as a hint.

Decompiled code

399 of 400 functions decompiled to C-like pseudocode; 14 more are imported from the page.

  • 1 of 400 functions could not be decompiled.

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.

Data segments

Each bar is one segment of the module's data: as wide as its size, as tall as its entropy. Bars above the dashed line are encrypted or compressed. 66 segments, 152.9 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

Imports (14)

Imports from wbg are wasm-bindgen glue. Each __wbg_… import calls one JavaScript function in the page, and its name says which (__wbg_fetch_… calls fetch). The __wbindgen_… imports are wasm-bindgen's own helpers for strings, errors and memory.

Exports (17)

Scripts that carry or load it

  • A script in the page carries it as text; the script is minified or bundled.

From public scans. A script loads a module when it fetches or compiles it.

In our sandbox

  • Produced 6 strings at run time (text not shown).

Checks we ran

  • Threat-feed matches: none
  • Names of mining software or pools: none
  • CryptoNight mining structure: not found
  • Hashing or cipher loops: none
  • Known hashing or cipher algorithms: none recognised
  • Encrypted or compressed data: 6 blocks, 124.4 KiB (81.4% of its data)
  • JavaScript stored inside: none
  • Other modules inside: none
  • Imports that read browser or page details: none
  • Function names: removed (usual in release builds)

Static checks of the file: nothing in it was run for these. A finding is a lead, not a verdict.

Shares code with

Other modules that contain some of the same functions. They are ranked by functions few modules have, so a language's own runtime does not link every module built with it. Shared code often means a shared library or the same developer. It is a lead, not a verdict.
