The hack involves the NTIA's office software, Microsoft's Office 365

Emails at the agency were monitored by the hackers for months, sources say

The National Security Council said the government is 'aware of the reports'

There is concern within the U.S. intelligence community that the hackers used a similar tool to break into other government agencies, according to sources

The hack is so serious it led to a NSC meeting at the White House on Saturday

'This is a nation state. We just don't know which one yet,' one source said

There is concern within the U.S. intelligence community that the hackers who targeted the Treasury Department and the Commerce Department's National Telecommunications and Information Administration used a similar tool to break into other government agencies, according to three people briefed on the matter. The people did not say which other agencies.
