Hackers have accessed the sensitive information of about one million Americans held by US outfit Nationwide Insurance.
The company said a "portion" of the company's computer network was breached affecting both customers and people who requested quotes.
Some 30,000 people in the state of Georgia were affected and more than 12,000 in South Carolina.
The California Department of Insurance said 5050 residents had names, Social Security numbers and other personal identifying data stolen in the breach. Credit card information was not accessed.
“It's a small portion of our customers and other non-policy holders that are impacted,” company spokeswoman Elizabeth Giannetti said.
The insurance company did not provided details on how the hack took place and said a third party company was hired immediately to investigate the breach and conduct a forensic examination of Nationwide's entire network.
