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
On 1 public scan, 2026-10-12.
Findings
Hashing or cipher loops. Leads, not verdicts: legitimate modules show these too.

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.
System interface
WASIStandard calls for clocks, random numbers and files. In a browser the page's own JavaScript provides them.

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: AES, SHA-1, SHA-256, SHA-512 or BLAKE2b. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

  • LmiAesEncKeySchedConstruct_C_AES · a table it reads
  • LmiAesEncKeySchedEncrypt_C_AES · a table it reads
  • DoAesEcbKnownAnswerTestAES · a table it reads
  • LmiSha1CtxUpdate_C_SHA-1 · its rotation amounts
  • LmiSha1CtxConstructSHA-1 · constants in its code
  • DoSha1KnownAnswerTestSHA-1 · constants in its code
  • LmiSha256CtxUpdate_C_SHA-256 · its rotation amounts
  • LmiSha256CtxConstructSHA-512 or BLAKE2b · constants in its code
  • DoSha256KnownAnswerTestSHA-512 or BLAKE2b · constants in its code

Decompiled code

874 of 875 functions decompiled to C-like pseudocode; 20 more are imported from the page.

  • 1 of 875 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. 411 segments, 59.9 KiB in all. The chart shows 64: the first 64 and every encrypted or compressed one.

Exports (20)

Scripts that carry or load it

  • cesia-zoom-access.mobile.preprod.mhgi.io carries it as text and loads it; the script is minified or bundled.

From public scans. A script loads a module when it fetches or compiles it.

Hosts and scripts inside

In our sandbox

  • Produced 3 strings at run time, listed below.
  • Ran a long busy loop (often hashing).

Strings it produced at run time

Text that appeared while it ran and is not in the file: decoded, decrypted or built by its code. Web addresses are shown as their host.

  1. `abcdefghijklmnopqrstuvwxyz{|}~
  2. !"#$%&'@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_
  3. !!!!"!!!!!!!!!!!!!!!!####$################%%%%&%%%%%%%%'%%%%%%%

Checks we ran

  • Threat-feed matches: none
  • Names of mining software or pools: none
  • CryptoNight mining structure: not found
  • Hashing or cipher loops: 4 functions (common in codecs and captchas)
  • Known hashing or cipher algorithms: AES, SHA-1, SHA-256, SHA-512 or BLAKE2b
  • Encrypted or compressed data: none
  • JavaScript stored inside: none
  • Other modules inside: none
  • Imports that read browser or page details: none
  • Function names: kept

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.
