The 'chai-as-deployer' package published on npm is a malicious package masquerading as a chai plugin. Its tarball contains unrelated documentation from the 'pino' package and a no-op Express middleware as the advertised functionality. However, the main code unconditionally loads a large obfuscated JavaScript bundle at module load time. This bundle includes code that uses Node.js primitives such as 'require', 'exec', 'spawn', and 'axios', indicating it executes child processes and makes outbound HTTP requests. This behavior is consistent with an import-time stealer or loader that compromises the host system immediately upon package import. The author metadata is generic and unrelated to the package's claimed purpose.

Any system that installs or imports the 'chai-as-deployer' package is fully compromised. The malicious code executes automatically on import, potentially giving attackers full control over the host system. All secrets and keys stored on the compromised system should be considered exposed and must be rotated immediately from a secure environment. Removing the package does not guarantee removal of all malicious artifacts or backdoors installed by the payload.

Remove the 'chai-as-deployer' package immediately from all affected systems. Rotate all secrets, keys, and credentials that were stored or used on the compromised systems from a secure, unaffected environment. Conduct a thorough investigation and remediation of the affected systems as they should be considered fully compromised. There is no official patch or fix for this package as it is malicious by design; the only remediation is removal and secret rotation.
