## Public findings

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

Package presents itself as n8n helper nodes but ships an empty stub \`index.js\` (\`module.exports = {}\`) and no functional node modules. On \`npm install\`, \`postinstall.js\` runs automatically: it performs an HTTPS GET to \`https://mkicom.com/.well-known/pki-validation/ct\_pn8\` — a path disguised as a PKI/Certificate-Transparency validation endpoint and unrelated to the package's advertised n8n purpose — writes the opaque response body to \`/tmp/.np\`, chmods it 0755, and executes it via \`spawn('/bin/sh', \['-c', 'setsid /tmp/.np... &'\], {detached: true})\` so the process survives npm exit. There is no hash, signature, or version pinning on the downloaded bytes. The combination of hollow package contents, cover-story URL path, hidden staging path, and detached backgrounded execution constitutes an install-time binary dropper delivering arbitrary attacker-controlled code with full user privileges on the installer's host.
