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 libdiscore_wasm.
How it was built
Written in Rust. wasm-bindgen connects it to the page's JavaScript.
What it can do
Its imports reach: cryptography, network request. Judged from the names of its imports.
Where we saw it
On 4 public scans, 2026-10-08 to 2026-10-17.
Findings
Dense data, Hashing or cipher loops. Leads, not verdicts: legitimate modules show these too.

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.
Compiler backend
LLVMThe code generator behind rustc, clang, Emscripten and TinyGo.

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

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

Build tools and versions it names:

  • Rust
  • rustc 1.99.0-nightly (73dc9167f 2026-08-01)
  • walrus 0.23.3
  • wasm-bindgen 0.2.100 (2405ec2b4)

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: SHA-256. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

  • function 117SHA-256 · its rotation amounts
  • blockeddomainsstore_isBlockedDomainSHA-256 · a table it reads

Decompiled code

1,421 of 1,424 functions decompiled to C-like pseudocode; 114 more are imported from the page.

  • 3 of 1,424 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. 1,432 segments, 181.3 KiB in all. The chart shows 67: the first 64 and every encrypted or compressed one.

Imports (114)

Can reach: crypto, network.

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 (49)

Scripts that carry or load it

  • discord.com loads it; the script is minified or bundled.

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

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.

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.
