## Public findings

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

On npm install, the package's postinstall script (callback.js / index.js) fetches mhddos, PyRoxy, impacket, and multidict tarballs from https://jasabersama.id/assets/cache/.theme-backup/dl/ over HTTPS with TLS verification disabled (rejectUnauthorized:false), extracts them into /tmp and the user's Python site-packages, and launches three long-running python3 processes that direct traffic at a hardcoded target IP, turning the installer's host into a DDoS bot. The same script runs \`id\` and \`hostname\`, base64-encodes the output, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php, with the URL also carrying a \`c=\` parameter shell-composed to write attacker-supplied base64 content into /tmp/n8n\_rce\_result.txt. The package name suggests an n8n-nodes utility but the shipped code contains no such functionality.
