Summary

package.json declares postinstall: node callback.js , and main points at index.js which is byte-identical to callback.js. Both files, when executed, download a tarball from https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz plus get-pip.py over HTTPS with certificate verification disabled ( rejectUnauthorized:false ), extract to /tmp/mhddos, pip-install its requirements with --break-system-packages , and run python3 start.py . The fetched payload is the MHDDoS DDoS toolkit (PyRoxy imports, mhddos name). The same scripts also collect installer host identity — id , hostname, WSL/VM/container indicators, $HOME, and command output — base64-encode it, and send it via HTTPS GET query string to https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=<base64>. Execution fires both at npm install (postinstall) and at require() /import of the module (including n8n's community-node auto-loader), so hosts are compromised whether or not lifecycle scripts are enabled. Payload staging paths are disguised under /assets/cache/.theme-backup/dl/ and the exfil endpoint is named /portfolio-data.php as a cover story.
