In 2021 a significant data exposure was reported involving the Turkish Message Management System known as IYS. This government mandated platform was designed to manage commercial electronic message permissions. The incident involved an unprotected database that exposed sensitive details of millions of Turkish citizens and businesses. The leaked records included contact information and permission statuses which are critical for marketing and communication privacy. Security researchers identified the exposure as a result of a misconfigured cloud storage or database instance that was accessible without authentication.
