No concrete installer-harm signals were identified in this version. Package name suggests transaction-building functionality, but without verified file-level evidence of behavior, intent cannot be determined. Routing to human review for manual inspection of the package contents, lifecycle scripts, and main module before any disposition is published.

Source: ghsa-malware (98a8b0307879bf2bc46dff29fe69118808e91074267b971b97953defd9c4972f)

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.
