ZoomInfo.com

ZoomInfo experienced a significant data exposure involving millions of records from its business contact database. The breach originated from an unprotected Elasticsearch instance which allowed unauthorized access to professional profiles. The exposed data included professional email addresses, phone numbers, job titles, and detailed work history. While ZoomInfo claimed the data was publicly sourced, the incident highlighted the risks of large scale data aggregation and the lack of security on cloud based storage servers used for business intelligence data.
