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.

Package contains only package.json and index.html, with main pointing at the HTML file. index.html mimics a Cloudflare Turnstile 'Just a moment' challenge and contains an obfuscator.io-obfuscated Turnstile callback that reconstructs a URL starting with 'https://lo' from a string-array and navigates the browser to it via window.location. There are no install lifecycle scripts (preinstall/install/postinstall/prepare) and main is HTML rather than JavaScript, so nothing executes on npm install or require of the package. The obfuscated redirect only fires when a browser loads the HTML (for example if served via a CDN like unpkg/jsdelivr), affecting a browser visitor rather than the developer who installs 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.
