Data Warehouse: How a Vendor for Half the Fortune 100 Exposed a Terabyte of Backups

Three publicly accessible Amazon S3 cloud storage buckets used by data management company Attunity were found to contain a significant amount of internal business documents. After being alerted by the UpGuard Data Breach Research team, Attunity, recently acquired by Qlik, secured the buckets and removed public access. The documents, many of which contained sensitive data, had been uploaded to the buckets since 2014. The exposed data also included credentials and personal employee information.
