The email system was compromised in recent weeks, at the same time as a White House network, and officials took the State system offline Friday, according to department officials
The maintenance has disrupted email traffic of State employees and the ability to access public websites, a senior department official told Nextgov on Sunday afternoon. State expects systems to be back up soon.
It is believed hackers backed by a nation state, likely Russia or China, infiltrated the White House system in September or October. Officials were still working to suppress abnormal behavior on that network as recently as late October.
