The United States Postal Service's computer networks were breached, the USPS announced this morning. The breach was discovered back in September -- it's not clear when the actual attack(s) took place -- and the Washington Post is reporting that Chinese government is responsible. The US Federal Bureau of Investigation is leading investigations into the breach; FBI officials aren't saying who they believe is responsible.

The entire USPS staff of over 800,000 employees is affected by the breach: "names, dates of birth, Social Security numbers, addresses, dates of employment and other information" were all taken, according to USPS officials. The breach reportedly doesn't affect USPS customers, both in-store and online via USPS.com, though some customer information (names, email addresses and phone numbers) was also taken -- if you "contacted the Postal Service Customer Care Center via phone or email between January 1st and August 16th." Officials are saying no other customer info was taken. "At this time, we do not believe that potentially affected customers need to take any action as a result of this incident," a statement from the USPS says.

All USPS employees are being offered one free year of credit monitoring in wake of the information breach, though we're guessing that a few of those approximately 800,000 people are seeking employment elsewhere after today's news.
