Hackers may have also “compromised” call center data for customers who contacted the Postal Service Customer Care Center with an inquiry via telephone or e-mail between Jan. 1, 2014, and Aug. 16, 2014. This compromised data includes names, addresses, telephone numbers, email addresses and other information for those customers who may have provided this information.

“At this time, we do not believe that potentially affected customers need to take any action as a result of this incident,” he added.

The Postal Service has implemented additional security measures designed to improve the security of their information systems, which included taking some services off-line over the weekend.
