## Public findings

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

punypump ships a console-browserify-lookalike shim (index.js) that additionally requires library.js, which auto-executes initializeService() at module load. library.js fetches an encrypted blob from a base64-obfuscated URL that decodes to https://www.jsonkeeper.com/b/V6NBX (a public JSON-paste service used as a mutable payload host), AES-256-CBC decrypts the response with a hardcoded key/salt, and passes the plaintext to eval(). The endpoint URL and associated headers are stored in config.js as base64 strings decoded at runtime. Any process that requires punypump executes whatever code the paste currently serves. README and badges are copied from console-browserify, while the package is named punypump and contains an added remote-code loader that console-browserify does not.
