## Public findings

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

Package masquerades as a chai-as-promised plugin / pino logger (README and exports copied from pino, including \`module.exports.pino = middleware\`) but on use spawns a detached Node process running lib/caller.js, which fetches a string from https://jsonkeeper.com/b/EXSIF and executes it via \`new Function.constructor("require", s)(require)\`. The fetched code runs with full Node privileges (require, fs, child\_process, network). The C2 URL and request headers are concealed by shadowing the local \`process\` object with fields named \`DEV\_API\_KEY\` / \`DEV\_SECRET\_KEY\` / \`DEV\_SECRET\_VALUE\`, and lib/const.js carries base64-encoded equivalents that decode to a second jsonkeeper.com paste and the header name \`x-secret-key\`. The remote paste is mutable and attacker-controlled, allowing arbitrary code execution on the installer's machine. Identity confusion with chai-as-promised / pino indicates the package exists to be installed by mistake.
