test890-auth@1.0.0

On npm install, index.js runs as a preinstall script and collects installer-side identifiers - home directory path, hostname, username, configured DNS servers, and the full contents of the consuming project's package.json - and POSTs them over HTTPS to the hardcoded out-of-band collector host wddbracmbzlaffkl9eivxzsvamgd43ss.oastify.com (Interactsh/Burp Collaborator). 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. ## Source: ghsa-malware (84c02a71147db9e3db14ba9c870f7ee08907ce4b1bfe2712026d878ef4df0685) 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.
