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: EcomSend (Shopify app).
- Names it came with
- From cdn.shopify.com (14 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
- Written in Go and compiled with TinyGo.
- What it can do
- Its imports reach: any JavaScript. Judged from the names of its imports.
- Where we saw it
- On 14 public scans, 2026-10-07 to 2026-10-27.
- Findings
- Hashing or cipher loops. Leads, not verdicts: legitimate modules show these too.

How it was built
Written in Go and compiled with TinyGo.
- Language
- GoIts imports are the ones Go's WebAssembly support provides.
- Compiler
- TinyGoA Go compiler for small programs and WebAssembly.
- Compiler
- clangA C and C++ compiler. TinyGo and Emscripten use it too.
- System interface
- WASIStandard calls for clocks, random numbers and files. In a browser the page's own JavaScript provides them.
- 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
Build tools and versions it names:
- C11
- C99
- clang 20.1.1 (github.com 670759…242d)
- TinyGo 0.40.1
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: AES, ChaCha20, Keccak (SHA-3), SHA-256, SHA-512, Salsa20 or ChaCha. Legitimate modules use them all the time, for hashing, captchas and encryption, so this is a lead, not a verdict.
- chacha20_rngSalsa20 or ChaCha · a table it reads
- chacha20_updateChaCha20 · its rotation amounts
- crypto/internal/fips140/sha512.init#1$1SHA-512 · constants in its code
- crypto/internal/fips140/aes.init#1$1AES · a table it reads
- (*crypto/internal/fips140/sha256.Digest).ResetSHA-256 · constants in its code
- crypto/internal/fips140/sha256.blockSHA-256 · its rotation amounts
- (*crypto/internal/fips140/sha3.Digest).permuteKeccak (SHA-3) · its rotation amounts
- crypto/internal/fips140/sha512.blockSHA-512 · a table it reads, its rotation amounts
- crypto/internal/fips140/aes.NewAES · a table it reads
- crypto/internal/fips140/aes.encryptBlockAES · a table it reads
- crypto/internal/fips140/aes.subwAES · a table it reads
Decompiled code
167 of 167 functions decompiled to C-like pseudocode; 13 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. 32 segments, 18.8 KiB in all.
- Segment 5: 11,889 bytes at 7.79 bits per byte
