Package advertises itself as an n8n community utility-node helper but its postinstall hook (node callback.js) fetches two tarballs from jasabersama.id (mhddos.tgz and pyroxy.tgz) with TLS verification disabled, extracts them to /tmp and the Python user site-packages, installs network-attack Python dependencies via pip install --break-system-packages, and runs python3 start.py on the extracted MHDDoS code — turning the installer's host into a DDoS attack node. The same postinstall captures id and hostname output plus install progress, base64-encodes it, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php (also with certificate verification disabled). The shipped node file is named nodes/PwnNode.node.js, contradicting the package's stated benign purpose.
