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.
Names it came with
Came with the GitHub repository thirstygithub/mathamatic-notes master · From cdn.jsdelivr.net · File name: love. 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
Its imports reach: runs code. Judged from the names of its imports.
Where we saw it
On 1 public scan, 2026-10-20.
Findings

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: CRC-32, MD5, SHA-1 or RIPEMD-160, SHA-1, SHA-1 or RIPEMD-160, SHA-256, SHA-512. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

  • function 998SHA-1 or RIPEMD-160 · constants in its code
  • function 999SHA-1 · constants in its code, its rotation amounts
  • function 1001SHA-256 · constants in its code, a table it reads, its rotation amounts
  • function 1003SHA-512 · constants in its code, a table it reads, its rotation amounts
  • function 7137CRC-32 · constants in its code
  • function 7157CRC-32 · constants in its code

Decompiled code

8,866 of 8,868 functions decompiled to C-like pseudocode; 361 more are imported from the page.

  • 2 of 8,868 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. 1,062 segments, 1.1 MiB in all. The chart shows 66: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

  • cdn.jsdelivr.net 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.

Checks we ran

  • Threat-feed matches: none
  • Names of mining software or pools: none
  • CryptoNight mining structure: not found
  • Hashing or cipher loops: 3 functions (common in codecs and captchas)
  • Known hashing or cipher algorithms: CRC-32, MD5, SHA-1 or RIPEMD-160, SHA-1, SHA-1 or RIPEMD-160, SHA-256, SHA-512
  • Encrypted or compressed data: 2 blocks, 9.2 KiB (0.8% of its data)
  • JavaScript stored inside: 2
  • Other modules inside: none
  • Imports that read browser or page details: 7
  • 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.
