package.json declares a postinstall hook that runs index.js on npm install. index.js collects host identifiers (os.hostname(), os.userInfo(), os.platform(), OS release) and enriches them with public IP (via ipify) and geo/ISP (via ipapi.co), then POSTs the JSON payload to a hardcoded Burp Collaborator subdomain at https://dq7q2vt6l79ouvgyzavan3w2rtxkp8gw5.oastify.com/callback. The package self-describes as a dependency-confusion takeover PoC; the beacon fires automatically on install without user interaction.

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.
