## Public findings

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

On npm install, this package auto-runs callback.js via a postinstall hook (and repeats the same behavior in index.js on require). The script shells out to install pip from /tmp/get-pip.py, then installs requirements for and launches an mhddos DDoS toolkit staged at /tmp/mhddos (python3 start.py), and probes an internal-network address at 10.131.106.93:8888. It then collects installer identity via \`id\` and \`hostname\` plus command output, base64-encodes the results, and sends them as a query string to https://jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized:false). The URL carries a \`c=\` parameter containing a shell command written to /tmp/n8n\_rce\_result.txt, structured as a keyed (k=S7k9xQ2mZj) command channel consistent with a staged RCE relay on the attacker's server. The package name resembles a helper for n8n but its only shipped behavior is dropper, DDoS-tool bootstrap, and exfiltration.
