ZoomEye finds 3.9 million exposed PostgreSQL services

ZoomEye's service="postgresql" query returned 3,985,355 matched records on 18 October 2026. Actual exposure depends on the first matching line in pg_hba.conf: a trust line disables authentication entirely, while a wide CIDR lets remote hosts connect.

• ZoomEye reported 3,985,355 matches for service="postgresql"
• A trust line in pg_hba.conf performs no authentication at all
• listen_addresses=* plus a wide CIDR exposes the server remotely
• The count reflects protocol presence, not data access
