Summary
Malicious code in dbt-language-server (npm)
Details
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.
Decision reason
OpenSSF Malicious Packages via OSV confirms dbt-language-server@1.0.1 as malicious (MAL-2026-6367): Malicious code in dbt-language-server (npm)
