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: libheif.
- 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
- On 13 public scans, 2026-10-04 to 2026-10-28.
- Findings
- Hashing or cipher loops. Leads, not verdicts: legitimate modules show these too.

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
1,792 of 1,792 functions decompiled to C-like pseudocode; 41 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.

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. 95 segments, 70.7 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

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: none recognised
- Encrypted or compressed data: none
- JavaScript stored inside: none
