## Public findings

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

The package's postinstall script writes /tmp/attack.py — a Python UDP/TCP flooder targeting the hardcoded IP 103.118.252.21 on ports 80/443 for 600 seconds — and launches it in the background via nohup python3. The same code path is present in index.js, which is declared as the package \`main\`, so require()ing the module re-triggers the dropper even when installation runs with --ignore-scripts. Both files also collect installer host identity (\`id\`, \`hostname\`, process listing, /proc/loadavg), base64-encode the data, and send it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false). The package presents itself as an n8n utility node but contains no such functionality; its only behavior is host reconnaissance exfiltration and using the installer's machine as a DDoS bot against a third-party target.
