If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

package.json declares a preinstall hook (`node index.js`) that runs automatically on `npm install`. index.js collects installer-side reconnaissance data — hostname, username, home directory, DNS servers, package metadata — and reads the contents of /etc/passwd and /etc/hosts from the installer machine, then POSTs the bundle over HTTPS to `p9z268f2xv8co3wtlpujplris9y2msah.oastify.com`, a Burp Collaborator subdomain used for out-of-band exfiltration. The package has empty author/description/license fields and ships no functionality beyond this payload. The name `dbt-language-server` shadows a plausible internal/private package, consistent with a dependency-confusion attack targeting organizations that use a dbt-related internal tool.

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.
