In early May, longtime data-breach hunter and security researcher Jeremiah Fowler discovered an exposed Elastic database containing 184,162,718 records across more than 47 GB of data. Typically, Fowler says, he is able to gather clues about who controls an exposed database from its contents—details about the organization, data related to its customers or employees, or other indicators that suggest why the data is being collected. This database, however, didn’t include any clues about who owns the data or where it may have been gathered from.
