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 package consists of a single index.html file declared as main. It impersonates a Cloudflare Turnstile 'security check' page and, when loaded in a browser via an npm CDN such as unpkg or jsdelivr, fetches an AES-CTR-encrypted destination host from https://api.keyval.org/get under a hardcoded key, decrypts it with a hardcoded AES key, and redirects the browser to a runtime-chosen URL under /api/strategies/check. The tarball contains no JavaScript entry, no lifecycle scripts (preinstall/install/postinstall/prepare), and no code reachable via require/import — main pointing at an.html file is inert in Node, so npm install and require() of this package execute nothing on the installer. The harm surface is end-user browsers that load the HTML through the npm CDN, not developers or build systems that 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.
