Dow Jones data leak exposes personal, financial information of 2.2M customers

Over two million Dow Jones customers had their personal and financial information exposed as the result of a public cloud configuration error, reports Dark Reading.

Chris Vickery, a cyber risk analyst at Mountain View, Calif.-based UpGuard, discovered the data leak May 30. The data — comprising customers' names, account information, physical and email addresses and last four digits of credit card numbers — were accessible on a cloud-based Amazon Web Services simple storage server. The server's permission settings allowed any AWS Authenticated User to download data, according to Dark Reading.

Amazon has more than one million users with AWS accounts, which are free.

UpGuard informed Dow Jones of the security issue. The company confirmed it secured the data June 6.
