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
Known library: Ruffle Flash emulator.
How it was built
Written in Rust. wasm-bindgen connects it to the page's JavaScript.
What it can do
Its imports reach: page content, cryptography, network request, storage, page address. Judged from the names of its imports.
Where we saw it
On 1 public scan, 2026-10-09.
Findings
Dense data, Hashing or cipher loops. Leads, not verdicts: legitimate modules show these too.

Analysis limits

Only its first 2,000 strings were read.

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.

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

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

Build tools and versions it names:

  • Rust
  • rustc 1.54.0 (a178d0322 2021-07-26)
  • walrus 0.19.0
  • wasm-bindgen 0.2.76

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.

Hashing and cipher code

Algorithms recognised from their published constants, tables and rotation amounts: CRC-32. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

Decompiled code

4,890 of 4,897 functions decompiled to C-like pseudocode; 304 more are imported from the page.

  • 7 of 4,897 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. 2,574 segments, 688.7 KiB in all. The chart shows 68: the first 64 and every encrypted or compressed one.

Imports (304)

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.

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.
