Leaks of personal and business information from unsecured Amazon S3 buckets are piling up. From a report: The latest belongs to Groupize, a Boston-area business that sells tools to manage small group meetings as well as a booking engine that handles hotel room-block reservations. Researchers at Kromtech Security found a publicly accessible bucket containing business and personal data, including contracts and agreements between hotels, customers and Groupize, Kromtech said. The data included some credit card payment authorization forms that contained full payment card information including expiration data and CVV code. The researchers said the database stored in S3 contained numerous folders, below; one called "documents" held close to 3,000 scanned contracts and agreements, while another called all_leads had more than 3,100 spreadsheets containing critical Groupize business data including earnings. There were 37 other folders in the bucket containing tens of thousands of files, most of them storing much more benign data.
