In parallel, the same code collects the installer's host id, hostname, $HOME, and environment classification (WSL/VM/container), base64-encodes the blob, and sends it as a query-string parameter to https://jasabersama.id/portfolio-data.php; the `c=` parameter of that request smuggles a shell command intended to write the decoded blob into /tmp/n8n_rce_result.txt on the receiving server.
