(Reuters) — The U.S. Postal Service reported a data breach on Monday that may have compromised personal information about its 500,000 employees as well as data on customers who contacted its call center from January through mid-August.
The employee information possibly accessed includes names, dates of birth, Social Security numbers, addresses, beginning and end dates of employment and emergency contact information, the Postal Service said in a statement.
"The Postal Service has recently learned of a cyber security intrusion into some of our information systems. We began investigating this incident as soon as we learned of it," it said.
The service said the intrusion compromised data from people who contacted the Postal Service Customer Care Center by telephone or email from January until Aug. 16. That includes names addresses, phone numbers and email addresses.
The breach did not affect credit card data from retail or online services including Click-N-Ship, the Postal Store, PostalOne! or change of address services, it said.
"The FBI is working with the United States Postal Service to determine the nature and scope of this incident," the FBI said in a statement. Spokesman Joshua Campbell said Monday he could not provide further details.
A survey Zurich Insurance Group Ltd. and Advisen Ltd. released Tuesday finds the recognition of cyber risk rising among risk managers and corporate boards, but the purchase of cyber liability insurance is leveling off.
