The package's package.json declares a preinstall: node index.js hook that fires automatically on npm install. index.js collects host reconnaissance data (os.hostname(), os.userInfo().username, home directory, DNS server configuration) and reads local system files including /etc/passwd and /etc/hosts, then HTTPS-POSTs the collected data to the hardcoded Burp Collaborator subdomain b5hv16nakzo45px5ga4ukkum8de52vqk.oastify.com. oastify.com is Burp Suite's out-of-band interaction service, commonly used as an attacker-controlled exfiltration sink. There is no legitimate functionality; the package's sole install-time behavior is host recon and data exfiltration.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
