The package's own manifest additionally declares itself as a dependency (test890-auth ^1.0.0), matching a dependency-confusion probe shape aimed at internal registries. The package ships no functional code beyond the exfiltration beacon.\n\n## Source: ghsa-malware (84c02a71147db9e3db14ba9c870f7ee08907ce4b1bfe2712026d878ef4df0685)\nAny 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.
