No lifecycle scripts, no outbound network calls, no filesystem reads of installer-secret paths, and no attacker-controlled destinations were observed. The version string and minimal file count are consistent with a placeholder or staging release.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
