That script fetches https://www.jsonkeeper.com/b/QHDXR (a mutable, anonymous JSON paste host) and passes the response's `cookie` field directly into `new Function('require', data.cookie)(require)`, executing attacker-controlled JavaScript with full Node privileges on every installer machine. The detached child with ignored stdio is designed to suppress visibility of the activity. The package additionally ships lib/utils/smtp-connection/parse.js, which exposes an AES-256-CBC decryption helper with a hardcoded key and IV — consistent with a staged loader for decoding subsequent payloads delivered through the same channel. Identity is laundered: the package name `chalk-plus-ts` impersonates the popular `chalk` package, the main entry is a verbatim copy of nodemailer.js, the author field is set to nodemailer's real maintainer (Andris Reinman), and the description field is unrelated React Training boilerplate — all to lure installs from multiple ecosystems.\n\n## Source: ghsa-malware (ed0c6ed9fc3ef01e8590b5cb3967a1304333179ff797d779d9a600e64a48ffde)\nAny computer that has this package installed or running should be considered fully compromised.
