Ensure your production .env file is never pushed to public or private version control systems like GitHub or GitLab. Your repository should only contain a template file, such as .env.example , which lists the keys but leaves the sensitive values blank. 4. Request De-indexing from Google

Google Dorking is a double-edged sword. It's a valuable resource for ethical researchers to find and fix security holes, but it's an equally powerful tool for attackers to exploit them. The "dbpassword+filetype+env+gmail+top" query is a clear reminder of the ever-present threat of misconfiguration.
