If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

package.json declares a preinstall hook that runs index.js on npm install. The script collects hostname, username, home directory, DNS servers, current working directory, and package.json contents, and reads /etc/passwd and /etc/hosts from the installer's host. The collected data is HTTPS-POSTed to a hardcoded Burp Collaborator subdomain at ipbtwv9063nc5hvhodh0s4u9x03rrhf6.oastify.com. The package has no advertised functionality beyond this exfiltration payload.
