An exclusive Dow Jones & Co. database of individuals and entities used by its customers for their compliance screening was unintentionally exposed due to a misconfigured and unsecured Elasticsearch database hosted on Amazon Web Services.

“This dataset is part of our risk and compliance feed product, which is entirely derived from publicly available sources. At this time our review suggests this resulted from an authorized third party’s misconfiguration of an AWS server, and the data is no longer available,” Dow Jones said in a written statement.
