Chinese hackers have been accessing the private mails of some top United States officials since April of 2010, which coincides with Hillary Clinton's tenure as secretary of state and her decision to use a private email server, Morning Joe's Willie Geist reported Tuesday.
"The email grab, first code-named Dancing Panda, targeted top national security and trade officials," Geist said. "It continued as late as 2014. The timing does overlap with Hillary Clinton's time as secretary of state and her use of a private email server."
"Many" top officials have been hacked, according to a high-level intelligence source and a top-secret document obtained by NBC News.
The Chinese also harvested the email address books of targeted officials, according to the document, reconstructing and then "exploiting the(ir) social networks" by sending malware to their friends and colleagues.
The time period overlaps with Hillary Clinton's use of a private email account while Secretary of State from Jan. 21, 2009 to Feb. 1, 2013. The names and ranks of the officials whose emails were actually grabbed, however, were not disclosed in the NSA briefing nor by the intelligence official.
