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: Skia CanvasKit graphics.
Names it came with
From www.gstatic.com (2 sites) · File name: canvaskit (2 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
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
On 2 public scans, 2026-10-23 to 2026-10-23.
Findings
Dense data, 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

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

Hashing and cipher code

Algorithms recognised from their published constants, tables and rotation amounts: CRC-32, CRC-32C. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

Decompiled code

10,487 of 10,494 functions decompiled to C-like pseudocode; 217 more are imported from the page.

  • 7 of 10,494 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. 2,340 segments, 416.2 KiB in all. The chart shows 65: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

  • www.gstatic.com loads it; the script is minified or bundled.

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.

  • Threat-feed matches: none
  • Names of mining software or pools: none
  • CryptoNight mining structure: not found
  • Hashing or cipher loops: 2 functions (common in codecs and captchas)
  • Known hashing or cipher algorithms: CRC-32, CRC-32C
  • Encrypted or compressed data: 1 block, 6.3 KiB (1.5% of its data)
  • JavaScript stored inside: none

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.
