A senior department official at the State Department, which reported the facts on a condition of anonymity, confirmed that an “activity of concern” was detected in the system concurrently with another cyber attack which hit the network at the White House computer network.

According to the official, none of the State Department’s classified systems were affected.

The security improvements have been completed on Monday or Tuesday.
“[The breach] has impacted some of our unclassified e-mail traffic and our access to public websites from our main unclassified system,” a senior State Department official told The New York Times on Nov. 16, adding that the department expected its systems to be up soon.
The incident was made public in October, but since then many other government entities were targeted by cyber attacks, including the U.S. Postal Service and the National Weather Service.
The official said The State Department the systems will be operating as normal as soon as possible, the near future, the man anyway hasn’t provided any information regarding the alleged responsible for the attack.
