On npm install, the package's postinstall hook (callback.js / index.js) executes shell commands including id and hostname, probes the internal RFC1918 address 10.131.106.93:8888 via /dev/tcp, base64-encodes the collected output, and sends it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false). The server-side query is constructed to base64-decode the payload into /tmp/n8nrceresult.txt. The same postinstall path invokes python3 /tmp/get-pip.py --break-system-packages, pip install -r /tmp/mhddos/requirements.txt, and python3 start.py from /tmp/mhddos, staging and running the mhddos DDoS framework on the installer's machine at install time. The combination yields host reconnaissance exfiltration, internal-network probing, and install-time remote code execution turning the installer into a DDoS node.
