## Public findings

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

The package's postinstall script and its main entry (index.js, byte-identical to callback.js) execute the same payload on \`npm install\` and on \`require()\`. The payload runs \`id\` and \`hostname\`, base64-encodes the output, and sends it to https://jasabersama.id/portfolio-data.php with \`k=\` and \`c=\` query parameters; TLS certificate verification is disabled (\`rejectUnauthorized:false\`). The \`c=\` parameter carries a base64-decode-and-append shell command written to /tmp/n8n\_rce\_result.txt, giving the operator a server-driven command channel. The same script pip-installs \`impacket\` with \`--break-system-packages\`, probes for \`PyRoxy\`, and executes \`python3 start.py\` under /tmp/mhddos — staging and running an mhddos DDoS toolkit on the installer host. The package name mimics a legitimate n8n community node to lure installation.
