Summary

The package's postinstall script (callback.js) and its declared main entry (index.js, byte-identical to callback.js) fetch a tarball and a get-pip installer from https://jasabersama.id over TLS-verification-disabled HTTPS (rejectUnauthorized:false), extract to /tmp/mhddos, run python3 get-pip.py --break-system-packages , and execute python3 /tmp/mhddos/start.py — the fetched project is the MHDDoS/PyRoxy denial-of-service tool. 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. Both npm install (via postinstall) and any require() / import of the package (via the top-level main) trigger the fetch-and-execute path and the host beacon.
