Description

The @rakuten-rewards/messaging-sdk npm package contains malicious code that compromises any computer on which it is installed or running. The presence of this package indicates a full system compromise, requiring immediate secret and key rotation from a different, trusted machine. Simply removing the package does not guarantee removal of all malicious software introduced by it.

Impact

Full system compromise on any computer with the package installed or running. All stored secrets and keys on the compromised system are at risk and must be considered exposed. The attacker may have persistent access beyond the presence of the package itself.

Defensive guidance

Remove the @rakuten-rewards/messaging-sdk package immediately. Rotate all secrets and keys from a different, uncompromised computer. Conduct a thorough investigation and remediation of the affected system, as removal of the package alone does not guarantee elimination of all malicious components.

Summary

The @rakuten-rewards/messaging-sdk package distributed via npm is identified as containing malicious code. Installation or execution of this package results in a full compromise of the affected system, potentially allowing an attacker complete control. Due to the severity of the compromise, all secrets and keys stored on the affected machine must be rotated from a separate, secure environment. Removal of the package alone is insufficient to ensure system integrity, as additional malicious components may persist.
