Earlier in the day, Russian Foreign Ministry spokeswoman Maria Zakharova said that Russia expects the United States to make legal assessment of media reports about alleged cyberattacks on Russian information systems by US hackers. She noted that the lack of US official reaction would mean that the United States is resorting to state cyberterrorism.
"The President has made it clear that we will take action to protect our interests, including in cyberspace, and we will do so at a time and place of our choosing," the White House official told RIA Novosti, in response to the question on the NBC reports of the US military allegedly infiltrating Russian infrastructure.
The official added that the general public would not be notified of the nature of the measures taken to defend the national interests.
"Consistent with the practice we have adopted in the past, the public should not assume that they will necessarily know what actions have been taken or what actions we will take. We are not going to discuss potential responses except to say that as we implement our responses, some responses you may see, and others you may not," the undisclosed source form the administration said.
