Dense data
Download .wasmSearch scans with this module

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
From experience.arcgis.com (2 sites) · File name: pe-wasm. Its build and the addresses it came from say so; whoever builds a module chooses these, so they are hints.
How it was built
Not named in the module.
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

The module names no language, compiler or build tool. Release builds often strip this information, and hand-written modules usually lack it.

Decompiled code

1,559 of 1,559 functions decompiled to C-like pseudocode; 18 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. 26,782 segments, 1.5 MiB in all. The chart shows 66: the first 64 and every encrypted or compressed one.

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.

Checks we ran

  • Threat-feed matches: none
  • Names of mining software or pools: none
  • CryptoNight mining structure: not found
  • Hashing or cipher loops: none
  • Known hashing or cipher algorithms: none recognised
  • Encrypted or compressed data: 2 blocks, 2.7 KiB (0.2% of its data)
  • JavaScript stored inside: none
  • Other modules inside: none
  • Imports that read browser or page details: none
  • 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.
