The crypto exchange said that it hired a third-party system for supplementary security screening of customers, which left the server open exposing customer records.

Upon discovery, QuickBits technicians took immediate steps to ensure that all the servers are protected behind firewalls. The open database was taken down on July 03, 2019.
