Dow Jones configured a cloud-computing service, which lead to exposing unauthorised access about subscribers, such as addresses and other private information.
According to a Dow Jones spokesman, around 2.2 million subscribers records were affected, including customer names, emails, physical addresses, usernames and the last four digits on credit cards.
The Dow Jones spokesman said: “We immediately remedied the situation and have no reason to believe that any data was taken.
“The data did not include full credit-card or account-login information that could pose a significant risk for consumers or require notification.”
Cyber security firm UpGuard notified Dow Jones of the exposed data after discovering it.
