No install-time lifecycle execution, no outbound network activity, no credential or environment access, no obfuscated payload, and no dropper or persistence mechanism were observed in the package contents. The package appears to be a prebuilt-binary or platform-conditional artifact of the kind commonly published alongside a main package to deliver per-OS/per-arch native assets.

Source: ghsa-malware (08b21b90b1f7b784f09be79386162a6d31ac2c89649a3dff65fbf67456594251) 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.
