Anthem, with 37 million customers the second-largest U.S. health insurer, said hackers infiltrated its computer network and gained access to personal information for “tens of millions” of customers and employees, including CEO Joseph Swedish, the Associated Press reports. Anthem is getting in touch with customers affected by a “very sophisticated” cyberattack that the company discovered last week. It said hackers gained access to names, birthdates, email address, employment details, Social Security numbers, incomes and addresses of people now or previously covered.
The Indianapolis-based insurer said credit card information wasn’t compromised. It has yet to find evidence that medical information such as insurance claims and test results was targeted or obtained. A spokeswoman said Anthem was working with federal investigators to figure out who was behind the attack. The FBI urged Anthem customers contacted by the company to report suspected instances of identity theft. Anthem Inc., which changed its name from WellPoint, runs Blue Cross Blue Shield plans in more than a dozen states, including California, New York and Ohio.
