Official description

No suspicious behaviors were identified in this package version. There are no lifecycle hook hazards, no outbound network calls to attacker-controlled destinations, no credential reads, no dropper or fetch-and-execute patterns, and no silent-relay mechanisms observed in the package contents.

Any computer that has this package installed or running should be considered fully compromised. 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.
