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.
