@years18/n8n-nodes-utils-helper-l@1.0.0

The package's postinstall script (callback.js) and its main module (index.js, loaded on require) are byte-identical droppers. On install and on load they fetch https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz and get-pip.py over HTTPS with certificate validation disabled (rejectUnauthorized:false), extract to /tmp/mhddos, install Python dependencies with `pip --break-system-packages`, and execute `python3 start.py` from the fetched archive (an mhddos DDoS toolkit). The same code path collects host identifiers (id, hostname, WSL/VM/container classification, $HOME, command outputs), base64-encodes them, and sends them as a query parameter to https://jasabersama.id/portfolio-data.php with a hardcoded key. Because package.json declares main:index.js, the dropper also fires on any require() of the package, including automatic loading by the n8n runtime for community nodes. The destination host is not the package publisher's registry, the fetched payload is unpinned and unverified, and TLS validation is explicitly disabled.
