The package contains a single index.html file declared as the package main, presenting a fake 'Just a moment...' / Cloudflare Turnstile page with heavily obfuscated JavaScript (string-array + shuffling style) that constructs a target URL from encoded strings and calls window.location.replace to redirect the browser. package.json declares no preinstall, install, postinstall, or prepare lifecycle scripts, and main points at an HTML file that Node cannot load as a module, so npm install and require() of the package do not execute the obfuscated code. The payload only runs if the HTML is opened in a browser. The artifact is not a functioning npm library and appears to be registry abuse hosting a browser-facing redirect/phishing lure rather than a supply-chain attack against 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.
