New information reveals possible cause of Anthem data breach

(NEWSCHANNEL 3) - There is new information into the cyber hack that stole millions of health insurance records from provider Anthem.

Authorities say the hackers obtained the credentials of five different employees, allowing them to get into the network, and it may have all happened since December.

Officials say names, social security numbers, and other personal information was stolen from up to 80 million Anthem customers.

The company said one of its computer administrators discovered on January 27 that an outsider was using his security credentials to log onto the system.

Investigators believe the hacker may have gotten the information through email phishing attempts.
