Summary
Malicious code in nihzvdeowx5 (npm)

The package contains only index.html (declared as main in package.json) and no JavaScript entry point, lifecycle scripts, or other module code. The HTML impersonates a Cloudflare Turnstile 'Just a moment' challenge page and runs obfuscator.io-obfuscated JavaScript that constructs a URL from string fragments beginning 'https://mail.microli' plus a runtime-decoded suffix and calls window.location.replace(...) on it, forwarding the current query string. Node.js cannot require() or import an HTML file, and no preinstall/install/postinstall hooks are declared, so npm install and require() of this package do not execute the redirect. The artifact appears designed to be served to a browser via a separate hosting/CDN path (for example, unpkg/jsdelivr) as part of a phishing lure rather than to attack developers who install the package.

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.
