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: adobe-pdf-engine.
Names it came with
File name: text-zce. 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.

Hashing and cipher code

Algorithms recognised from their published constants, tables and rotation amounts: SHA-1. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.

  • function 2028SHA-1 · its rotation amounts
  • function 3344SHA-1 · constants in its code
  • function 6064SHA-1 · constants in its code

Decompiled code

18,233 of 18,248 functions decompiled to C-like pseudocode; 67 more are imported from the page.

  • 15 of 18,248 functions could not be decompiled.

Beyond WebAssembly 1.0: Exception handling (6,632 functions).

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. 3,979 segments, 1.5 MiB in all. The chart shows 72: the first 64 and every encrypted or compressed one.
