In January 2021 the website Rankly was part of a massive data breach involving an unprotected MongoDB database. The incident exposed millions of user records including personal details and authentication identifiers. Security researchers discovered the open database which allowed unauthorized access to sensitive information without any password protection. The leak impacted users worldwide who utilized the platform for rankings and social feedback. The data was subsequently circulated in the darknet community and added to major breach notification services.
