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

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.

• function 66ChaCha20, Salsa20 or ChaCha · constants in its code, its rotation amounts

Decompiled code

1,634 of 1,635 functions decompiled to C-like pseudocode; 52 more are imported from the page.

• 1 of 1,635 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. 1,653 segments, 1.4 MiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

• wbstatic.webullfintech.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 3 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: 1 function (common in codecs and captchas)
• 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.
