US officials have revealed that Russian hackers managed to compromise the Pentagon’s Joint Staff unclassified email system last month. Calling it a “sophisticated cyberattack,” they said the intrusion occurred around July 25, following which the system was shut down and taken off line.
The attack, which affected around 4,000 civilian and military employees of the Joint Chiefs of Staff, apparently used an automated system that quickly collected large amounts of data, and then distributed it to thousands of accounts on the Internet.
