Hacking teams traced back to China are caught breaking into the computers of the Obama and McCain campaigns, resulting in high-level warnings to Chinese officials to stop. The computers, laptops, and mobile devices of top campaign aides and advisers who receive high-level briefings are particularly targeted. “Spear phishing” is used to get targets to open an attachment containing a virus that would allow data to be stolen from their computer.

Obama campaign manager David Plouffe will later say he got a call in the middle of August 2008 alerting him to the attack and that the FBI was investigating. However, the virus is extremely sophisticated, and it takes months for it to be completely removed from the networks of the two campaigns.

In a May 2009 speech, President Obama will make a general mention of the attacks: “Hackers gained access to emails and a range of campaign files, from policy position papers to travel plans.” However, the involvement of China’s government won’t be publicly revealed until June 2013.

Dennis Blair, director of national intelligence from 2009 to 2010, will comment that year, “Based on everything I know, this was a case of political cyberespionage by the Chinese government against the two American political parties. They were looking for positions on China, surprises that might be rolled out by campaigns against China.” (NBC News, 6/6/2013)

December 22, 2015: Clinton’s private server was once infected by a computer virus.

When Bryan Pagliano, who managed Clinton’s private server, is interviewed by the FBI on this day, he will mentioned that he recalled finding “a virus” on her server at some point. But according to the FBI, he “could provide no additional details, other than it was nothing of great concern. FBI examination of the [server] and available server backups did not reveal any indications of malware.” (Federal Bureau of Investigation, 9/2/2016)
