A U.S. Postal Service data breach has potentially compromised the personal information of 800,000 employees. The data breach of some USPS information systems is being investigated by the FBI. Names, dates of birth, Social Security numbers, addresses and other information of Postal Service employees may be compromised. The breach may also affect customers who called or emailed the USPS customer care center between January and mid-August. Credit and debit card accounts were not breached in the attack, the Postal Service said. Chinese hackers are suspected in the breach, according to a report in the Washington Post.”]
