If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

On npm install, the script fetches https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz and pyroxy.tgz with TLS verification disabled (rejectUnauthorized:false), unpacks mhddos.tgz to /tmp/mhddos and pyroxy.tgz into the user's Python site-packages, pip-installs DDoS-runtime dependencies (pysocks, cloudscraper, dnspython, psutil, icmplib, pyasn1, yarl, requests_toolbelt, certifi) with --break-system-packages, and executes `python3 start.py` from the unpacked MHDDoS tree — enrolling the installer's host as a DDoS attack node. The same postinstall runs `id` and `hostname`, base64-encodes the output alongside payload-install results, and smuggles it to https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj\u0026c=\u003cbase64\u003e via a GET request with TLS verification also disabled.
