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.

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.

Hashing and cipher code

Algorithms recognised from their published constants, tables and rotation amounts: CRC-32, SHA-1. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

• function 1337SHA-1 ·
• function 1339SHA-1 · constants in its code

Decompiled code

12,044 of 12,046 functions decompiled to C-like pseudocode; 87 more are imported from the page.

• 2 of 12,046 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. 3,275 segments, 719.9 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

• estatement.bpstelephone.com loads it.

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.

In our sandbox

• Produced 16 strings at run time, listed below.
• Ran a long busy loop (often hashing).

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: CRC-32, SHA-1
• 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.
