    Summary: Malicious code in @years18/n8n-nodes-utils-helper-p (npm)

    Details: Source: amazon-inspector (0c2eddb1197cb0c902c559648ce926f5c58d1a2552d05c8e1c49dd814fdf8804) 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.
