subapp-pkg-util@99.0.1

Summary

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.
