Billions Spent on U.S. Cyberdefenses Failed to Detect Giant Russian Hack – The New York Times

So far, though, President Trump has said nothing, perhaps aware that his term in office is coming to an end just as it began, with questions about what he knew about Russian cyberoperations, and when. The National Security Agency has been largely silent, hiding behind the classification of the intelligence. Even the Cybersecurity and Infrastructure Security Agency, the group within the Department of Homeland Security charged with defending critical networks, has been conspicuously quiet on the Russian mega hack.

Mr. Blumenthal’s message on Twitter was the first official acknowledgment that Russia was behind the intrusion.

Trump administration officials have acknowledged that several federal agencies — the State Department, the Department of Homeland Security, parts of the Pentagon as well as the Treasury and the Department of Commerce — had been compromised. Investigators were struggling to determine the extent to which the military, intelligence community and nuclear laboratories were affected.
