The 'prettier-logger' npm package versions 0.1.4, 0.1.5, and 0.1.6 have been identified as containing malicious code. Installation or execution of these versions may result in full compromise of the host system, including unauthorized access to stored secrets and keys. Due to the severity of the compromise, simply uninstalling the package may not remove all malicious artifacts or backdoors introduced by the attacker.

Systems with the affected versions of 'prettier-logger' installed or running are considered fully compromised. Attackers may have gained complete control over the system, risking exposure and theft of sensitive credentials and secrets. The integrity and confidentiality of the affected system cannot be assured without comprehensive remediation.

Immediate removal of the 'prettier-logger' package versions 0.1.4, 0.1.5, and 0.1.6 is required. All secrets and keys stored on the compromised system should be rotated from a separate, trusted environment. Due to the potential for persistent malicious code beyond the package itself, a full system investigation and remediation is recommended. No official patch or fix is indicated; therefore, avoidance of these package versions is critical.
