package.json declares a preinstall hook (node./dist/index.d.js) that runs automatically on npm install. The script at dist/index.d.js decodes a base64-wrapped payload via Buffer.from(..., 'base64').toString('utf-8') and dispatches it to eval, where the eval identifier is obfuscated by reconstructing it from the char-code array [101,118,97,108] and accessed via globalThis[tag](text). The decoded payload fetches https://everydaynodechecker-39143n.vercel.app/api/key?mem=root2 and passes the response body to eval, resulting in execution of attacker-controlled code fetched from a remote endpoint on every installer's machine. The base64 wrapping, char-code eval reconstruction, and remote fetch-and-eval together form an install-time remote code execution chain against any consumer of this package.

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.
