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
Known library: Amazon IVS video player.
Names it came with
From player.twitch.tv (5 sites). Its build and the addresses it came from say so; whoever builds a module chooses these, so they are hints.
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.

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.

Decompiled code

3,312 of 3,315 functions decompiled to C-like pseudocode; 52 more are imported from the page.

  • 3 of 3,315 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. 291 segments, 111.0 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

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.
