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.

System interface

WASIStandard calls for clocks, random numbers and files. In a browser the page's own JavaScript provides them.

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.

Hashing and cipher code

Algorithms recognised from their published constants, tables and rotation amounts: ChaCha20, Salsa20 or ChaCha. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

Decompiled code

2,658 of 2,658 functions decompiled to C-like pseudocode; 35 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.

File layout

WebAssembly binary format version 1, core module, 11 sections.

Memory

128 pages (8.0 MiB), up to 32,768 pages (2.0 GiB), imported from the page as env.memory

Table

634 entries, no upper limit, funcref

Start function

function 36, which runs as soon as the module is loaded

Element segments

Declared data segments

Function names

none (names were stripped)

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. 432 segments, 91.3 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

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

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

In our sandbox

• Produced 2 strings at run time, listed below.

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: ChaCha20, Salsa20 or ChaCha
• Encrypted or compressed data: none
• 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.
