The tarball contains only package.json and index.html, with no lifecycle scripts and main set to index.html. The HTML page mimics a Cloudflare Turnstile 'checking your browser' screen; its Turnstile completion callback runs obfuscator.io-style JavaScript that reconstructs a destination URL beginning with 'https://mn' from a custom-base64 string table and calls window.location.replace(targetUrl) forwarding all current query parameters. npm does not auto-execute an HTML main on install or require, so installing or requiring the package does not run this code on a developer's machine. The harm target is browsers of any site that serves this HTML as a phishing/redirect landing page — not npm installers. The package appears to abuse npm as a hosting/staging channel for a browser-side redirect lure rather than as a supply-chain attack against installers.

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.
