Description

The npm package new-route-matrix was found to contain malicious code. Any system with this package installed or running should be considered fully compromised. Secrets and keys stored on the affected system should be rotated immediately from a different, secure computer. Removing the package alone does not guarantee removal of all malicious software introduced by it.

Impact

Full system compromise on any computer with the new-route-matrix package installed or running. Potential exposure and theft of secrets and keys stored on the system. The attacker may maintain persistent access beyond the presence of the package itself.

Defensive guidance

Immediately remove the new-route-matrix package from all affected systems. Rotate all secrets, keys, and credentials that were stored on the compromised systems using a separate, secure computer. Conduct a thorough investigation and remediation to identify and remove any additional malware or backdoors that may have been installed. Do not rely solely on package removal for remediation.

Summary

The new-route-matrix package on npm contains malicious code that compromises any computer on which it is installed or executed. The compromise is severe enough that all stored secrets and keys on the affected system must be rotated from a separate, uncompromised device. Due to the nature of the compromise, simply uninstalling the package may not fully remediate the infection, as the attacker may have established persistent control or installed additional malware.
