Hacking attempts on McCain’s and Obama’s campaign networks may have come from China. From Financial Times:
Earlier this summer, the Secret Service and Federal Bureau of Investigation warned Barack Obama’s and John McCain’s campaign teams that their computer networks had been compromised by foreign hackers.
The cyber attackers successfully downloaded large quantities of information from the campaign networks, which security agencies believed was an attempt to learn more about the contenders’ policy positions.
The official said investigators had determined that the attacks originated from China, but cautioned that they had not ascertained whether they were government-sponsored, or just unaffiliated hackers.
