US State Department’s unclassified e-mail systems hacked

The US State Department’s unclassified e-mail systems were the victim of a cyberattack in recent weeks, around the same time as White House systems were breached, a senior US official said.

The official, who spoke on condition of anonymity, said no classified systems were compromised. Portions of State’s unclassified systems have been shut down to improve security but should be back online shortly.
