## Public findings

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

The package's postinstall hook runs node callback.js, and package.json declares main=index.js which is byte-identical to callback.js, so both npm install and require() of the package execute the same payload. The payload writes /tmp/attack2.py — a threaded UDP/TCP flood loop targeting 103.118.252.21 for 900 seconds — and launches it via \`nohup python3 /tmp/attack2.py &\`, weaponizing the installer's host and IP as a DDoS bot. In parallel, it collects the output of \`id\`, \`hostname\`, a process check and /proc/loadavg, base64-encodes it, and sends it over HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized:false). The package is presented as an n8n utility helper but ships no such functionality; its only observable behavior is the DDoS launcher and host-identity beacon.
