Package ships a single index.html that mimics a Cloudflare Turnstile 'Just a moment...' verification page. An obfuscated (obfuscator.io-style) script assembles a .club URL at runtime from string-array lookups, copies the current page's query parameters onto it, and navigates the browser to that URL via window.location. The package declares no JS main, no bin entry, and no lifecycle scripts (preinstall/install/postinstall/prepare), and contains no binding.gyp, so npm install and require() of this package do not execute any code on the installer's machine. The redirect logic only runs in a browser that renders index.html — for example, if the file is served from a CDN or hosting surface fronted by the npm registry.

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.
