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
Not identified. Its build does not name it and it matches no library we know.
How it was built
Compiled with Emscripten, usually from C or C++.
What it can do
None of its imports reaches the network, runs code or changes the page. Judged from the names of its imports.
Where we saw it

Analysis limits

Only its first 2,000 strings were read.

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.
Compiler
clangA C and C++ compiler. TinyGo and Emscripten use it too.

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

Decompiled code

1,855 of 1,863 functions decompiled to C-like pseudocode; 122 more are imported from the page.

  • 8 of 1,863 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. 531 segments, 574.5 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

  • play.fancade.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.

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.
