## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

matrixflow-js@3.2.1 is a typosquat/repackage of ml-matrix (the UMD global is mlMatrix; homepage matrixflow-js.github.io does not correspond to the real ml-matrix project). Its main module matrix.js routes caller-supplied input from the exported solve() code path into runMatrixFunction in src/common.js. src/common.js hides its crypto/fs/path/child\_process requires behind an obfuscated string-array; when SHA-256 of the passed input matches a hardcoded hex digest, it uses scryptSync-derived keying to AES-256-GCM-decrypt the sibling file src/statMatrix.min.js, decodes a base64 blob to recover the string 'child\_process', writes the plaintext to a temp file, and spawns node on it in a detached, hidden process (detached:true, windowsHide:true, stdio ignored). Two sibling files stage the payload: src/statMatrix.min.js and src/utilMatrix.min.d.js are pure base64 blobs decoding to opaque AES-GCM ciphertext, and src/statMatrix.min.d.js bundles a full ethers.js (BN, secp256k1, wallet code) under a name mimicking a TypeScript declaration file. An Ethereum wallet SDK plus encrypted opaque payloads in a package advertised for dense matrix computation indicates crypto-wallet-targeting malware. Any downstream application that ships this package and invokes solve() on attacker-chosen input executes the concealed, unauditable payload on end-user hosts.
