Description

The npm package poly-utils version 1.0.0 contains malicious code or depends on a package with malicious code. Any system with this package installed should be considered fully compromised, requiring immediate rotation of all secrets and keys from a different machine. Removal of the package alone may not eliminate all malicious software introduced by it.

Impact

Systems with poly-utils version 1.0.0 installed are considered fully compromised. Attackers may have gained full control over the affected system, potentially exposing all stored secrets and keys. The compromise may persist even after removal of the package, indicating possible persistence mechanisms or additional malware installed.

Defensive guidance

Remove the poly-utils package version 1.0.0 immediately. Rotate all secrets and keys stored on the compromised system from a different, secure machine. Because full system compromise is likely, consider rebuilding or thoroughly cleaning the affected system to ensure removal of all malicious components.

Summary

The poly-utils package version 1.0.0 on npm was found to contain malicious code or a dependency that includes malicious code. According to sources including Amazon Inspector and the GitHub Security Advisory for malware, installation or execution of this package compromises the host system fully. The advisory warns that all secrets and keys stored on the compromised system should be rotated immediately from a separate, secure system. Simply removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the package.
