Health insurer Anthem hit by hackers Health insurer Anthem confirmed earlier this year that the hackers infiltrated its computer network and gained access to personal information for tens of millions of customers and employees, including CEO Joseph Swedish.

The nation’s second-largest health insurer said it was contacting customers affected by what it calls a ‘very sophisticated’ cyberattack. It said hackers gained access to names, birthdates, e-mail address, employment details, social security numbers, incomes and street addresses of people who are currently covered or have had coverage in the past.

The Indianapolis-based insurer said credit card information wasn’t compromised, and it has yet to find evidence that medical information such as insurance claims and test results was targeted or obtained. It was still trying to determine exactly how many people were affected.

A spokeswoman said the insurer was working with federal investigators to figure out who was behind the attack.
