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

    Details: Source: amazon-inspector (d8582b5c27e0823f2431d4069a971d7d106d92f6ddb68bf9b7b443fe98b930ea) 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.
