If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The tarball contains only package.json and index.html. package.json declares main: index.html and no lifecycle scripts (preinstall/install/postinstall/prepare). index.html renders a fake Cloudflare 'Just a moment...' interstitial and, on Turnstile callback, runs obfuscator.io-style JavaScript that constructs a URL and calls window.location.assign to redirect the browser. Node cannot load an HTML file as a module, so nothing executes on npm install or on require of this package. The abuse surface is browsers that load this HTML via an npm-backed CDN (e.g., unpkg), not developers installing 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.
