Package array-inline@2.0.5 was scanned across 5 files with no a static rule matches and no traced behaviors indicating credential access, network exfiltration, install-time code execution, or persistence. No lifecycle scripts fetching or executing remote content, no reads of installer secret paths, and no hardcoded external destinations were observed.

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.
