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.

The same code path is present in index.js, which is declared as the package `main`, so require()ing the module re-triggers the dropper even when installation runs with --ignore-scripts. Both files also collect installer host identity (`id`, `hostname`, process listing, /proc/loadavg), base64-encode the data, and send it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false).
