A contractor working for the Republican National Committee (RNC) left more than 198 million Americans' personal information exposed online in a misconfigured database, UpGuard researcher Chris Vickery recently found.

The information was held in an unprotected Amazon Web Services S3 bucket owned by Deep Root Analytics (DRA), and had been compiled by DRA along with two other Republican contractors, TargetPoint Consulting and Data Trust.

Anyone with any Internet connection could access the data simply by accessing the Amazon subdomain "dra-dw," for "Deep Root Analytics Data Warehouse." Read more.
