Description

The npm package pretty-pino-logger 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 rotation of all secrets and keys from a separate, secure machine. Removing the package alone does not guarantee removal of all malicious software introduced by it.

Impact

Systems with any of the affected versions of pretty-pino-logger installed or running are considered fully compromised. Attackers may have gained full control over the system, potentially accessing or exfiltrating sensitive data, credentials, and secrets. This level of compromise necessitates immediate security incident response actions including key rotation and system remediation.

Defensive guidance

Remove the malicious pretty-pino-logger package immediately. Rotate all secrets and keys stored on the compromised system from a separate, secure computer. Because full system compromise is likely, consider rebuilding or thoroughly cleaning the affected system to ensure complete removal of malicious artifacts.

Summary

The pretty-pino-logger npm package versions 1.0.0 through 1.0.4 and 2.0.1 through 2.0.2 contain malicious code that fully compromises affected systems. Installation or execution of this package grants an attacker full control over the host computer. Due to the severity of the compromise, all secrets and keys stored on the affected system must be rotated from a different, uncompromised device. Removal of the package does not ensure complete eradication of the malicious presence.
