U.S. Postal service hacked and 500k+ employess and public data breached

An anonymous reader writes: The U.S. Postal Service has admitted that it has suffered a massive security breach, with the disclosure to hackers of the personal details of over 500,000 USPS workers, along with details supplied by members of the public when contacting Postal Service call centers between January and mid-August of 2015.

The breach is a hard blow to the integrity and reputation of the USPS's internal security set-up, the Corporate Information Security Office (CISO). In 2012 CISO reports that it blocked 257 billion unauthorised attempts to access the USPS network, 66,734 attempts to distribute credit-card information, 1,278 attempts to reveal USPS-ordained credit-card transactions and 345,342 attempts to distribute social security numbers.
