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
Known library: dotLottie animation player.
Names it came with
Came with the npm package @lottiefiles/dotlottie-web 0.46.0 · From cdn.jsdelivr.net · File name: dotlottie-player. Its build and the addresses it came from say so; whoever builds a module chooses these, so they are hints.
How it was built
Written in Rust and compiled with Emscripten.
What it can do
None of its imports reaches the network, runs code or changes the page. Judged from the names of its imports.

How it was built

Written in Rust and compiled with Emscripten.

Language
RustThe Rust compiler (rustc) left its name in the module.
Compiler
EmscriptenThe toolchain that compiles C and C++ (sometimes Rust) for the web. It comes with the JavaScript that loads the module.
Compiler backend
LLVMThe code generator behind rustc, clang, Emscripten and TinyGo.

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.

What it is made of

22 Rust crates from crates.io, with the versions it was built with:

Read from text the build left in the module: source paths, build metadata and .NET metadata. Whoever builds a module can change or remove it, so treat it as a hint.

Hashing and cipher code

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

Decompiled code

5,278 of 5,280 functions decompiled to C-like pseudocode; 116 more are imported from the page.

  • 2 of 5,280 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. 1,346 segments, 278.4 KiB in all. The chart shows 65: the first 64 and every encrypted or compressed one.

Scripts that carry or load it

  • studenthusetunionen.se 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.

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.
