## Public findings

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

The package's postinstall entry (callback.js) and its declared main entry (index.js) contain byte-identical top-level code that (1) writes a Python UDP/TCP flooding script to /tmp/attack2.py targeting the hardcoded IP 103.118.252.21 for 900 seconds and launches it via \`nohup python3 /tmp/attack2.py... &\`, and (2) collects the installer's shell id, hostname, /proc/loadavg and process listing, base64-encodes the blob, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php with TLS verification disabled (\`rejectUnauthorized: false\`). Both triggers fire automatically: the postinstall runs on \`npm install\`, and the identical main module runs again when n8n loads the community node via \`require()\`. The package presents itself as an n8n utility helper but ships no functional node code matching that purpose.
