The 'epic-games-nav-shared' npm package versions 0.0.1-security, 99.9.2, and 1.9.9 are identified as malicious. Installing or running this package can lead to full compromise of the host computer, potentially allowing attackers to access sensitive information such as secrets and keys. The package acts as a backdoor or malicious payload, and its presence indicates a severe security breach. Due to the nature of the compromise, simply uninstalling the package may not fully remediate the infection.

Any system with this package installed or running should be considered fully compromised. Attackers may have gained full control over the system, including access to all stored secrets and keys. This can lead to unauthorized data access, credential theft, and further lateral movement or persistence within the environment.

Remove the 'epic-games-nav-shared' package immediately from all affected systems. Rotate all secrets and keys that were stored on the compromised machines, performing this rotation from a different, trusted system. Due to the potential for persistent malicious software beyond the package itself, consider a full system investigation and remediation. No official patch or fix is available; remediation relies on removal and secret rotation.
