On `npm install`, the package's preinstall hook executes index.js which collects installer host and identity information (hostname, platform, OS release, `whoami`, `id`, current working directory, `uname -a`), base64-encodes the blob, splits it into DNS labels, and issues `nslookup` queries against the hardcoded subdomain `hufw8vt7sk2vw016qzzgek9gr7x0ls9h.oastify.com`. This tunnels installer identity and host details out-of-band via DNS to a Burp Collaborator endpoint, bypassing HTTP egress filtering. The package.json also declares a self-referential unpinned dependency on `test899-auth: ^1.0.1`, consistent with a probing/PoC harness shape. The name and behavior are consistent with a research or malicious probe package rather than a functional authentication library.

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.
