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.js. index.js is not JavaScript source: it is a base64-encoded JSON blob that decodes to a configuration object containing a `cdn` field whose value base64-decodes to the string 'funnull' (a CDN provider previously sanctioned for hosting malicious content), a `domain` field of https://apiyf.dq87771.com, an additional endpoint https://api.dq87771.com, and a hardcoded token (800cf3d509b44bf7bfd32529dc3ff597). The package declares no lifecycle scripts and index.js is not valid JavaScript, so `npm install` and `require()` of this package alone do not execute code. The shape — a non-functional package that carries only remote-configuration data pointing at Funnull-tagged infrastructure and an authentication token — is consistent with the config half of a two-package loader/config split, where a companion package reads this configuration to fetch and execute payloads from the referenced hosts.

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.
