A massive database belonging to the Quickdns service was exposed in an open access incident during June 2023. The leak includes approximately 9.5 million records containing email addresses and specific system timestamps indicating when each record was added. The exposure occurred due to an unsecured server or misconfigured database that allowed public access to internal user data without authentication. While the primary data point is email addresses, the scale of the leak makes it a significant target for phishing campaigns and credential stuffing attacks.
