coondoggie writes: "The rattling of cyber swords could be heard today as the Pentagon confirmed computer hackers had gained access to an unclassified e-mail system in the office of Defense Secretary Robert Gates, but then declined to say that the Chinese army was responsible for it. The Financial Times this week quoted current and former U.S. officials as saying that Chinese People's Liberation Army hackers broke into a Defense Department network in June and removed data. Pentagon spokesman Bryan Whitman said that an attack did occur in June but declined to identify the origin of the threat. It is often difficult to pinpoint the true origin of an intrusion into computer systems and even more difficult to tie the intrusion to a specific nation or government, he said. http://www.networkworld.com/community/node/19041"
