(NBC NEWS) The FBI is investigating a potentially massive computer hacking attack on Anthem, Inc., one of the nation’s largest health insurance companies, a federal official told NBC News late Wednesday. The company confirmed the attack.

“Cyber attackers executed a very sophisticated attack to gain unauthorized access to one of Anthem’s IT systems and have obtained personal information relating to consumers and Anthem employees who are currently covered, or who have received coverage in the past,” company spokeswoman, Kristin Binns, said in a statement.

The company said the hacked database contains 80 million records but they anticipate the actual number individuals affected will be lower.
