The U.S. Postal Service said Monday it had been hacked, potentially compromising sensitive information about its employees such as names and addresses, Social Security numbers, emergency contacts and other information.
The FBI said it was leading a multi-agency investigation into the breach, which took effect in mid-September. The intrusion was similar to those reported by other federal agencies as well as in the private sector. The agency isn’t recommending that its customers take any action.
“The intrusion is limited in scope, and all operations of the Postal Service are functioning normally,” said Postal Service spokesman David Partenheimer.
He said that customers at local post offices or those using its website, usps.com, were not affected, but that people who used its call center may have had telephone numbers, email addresses and other information compromised.
The Postal Service provided no immediate information on how many people may have been affected. It said it employs over 800,000 workers.
