Although warned of the possibility earlier this summer by the Secret Service and the F.B.I, both Barack Obama’s and John McCain’s campaign networks were compromised by hackers from China. Large amounts of policy related information were downloaded.
According to China Digital Times, the hackers successfully downloaded large amounts of information from both campaign networks. It is not known if the Chinese hackers were government-sponsored.
Financial Times.com reports that the details of this attack were first revealed by Newsweek. Experts on the Obama team thought the attacks either came from China or Russia.
The Secret Service alerted both campaigns after security breaches were detected and then both campaigns hired “private cyber security companies to address the breaches.”
Chinese military hackers broke into the Pentagon system last year causing a “most serious breach of the military's computer network.”
