The Chinese military hacked into a Pentagon computer network in June in
the most successful cyber attack on the US defence department, say
American ­officials.

The Pentagon acknowledged shutting down part of a computer system
serving the office of Robert Gates, defence secretary, but declined to
say who it believed was behind the attack.
