NBC News Russian government hackers compromised the network of the

Democratic National Committee so well that they were reading

private emails and chats for the past year.

The revelation comes just a month after the nation's top spy warned that

hackers were indeed spying on both candidates.

"We've already had some indications of that," James

Clapper, the director of national intelligence, said in May.

"Our team considers them some of the best adversaries

out of all the numerous nation-state, criminal and

hacktivist/terrorist groups we encounter on a daily basis,"

Alperovitch wrote.

"The intrusion is not totally surprising: The Chinese

government reportedly hacked both Obama and McCain in 2008, and hackers

tried repeatedly to break into the campaign accounts of Obama

and Romney in 2012.Hackers working for foreign governments can gain valuable

insight into a presidential candidate's mindset before they take

office, or uncover private communications that might give their

country a leg up in diplomatic negotiations.
