Russia has said it had “nothing to do” with the hacking.
While Trump downplayed the impact of the hacks, the Cybersecurity and Infrastructure Security Agency has said it compromised federal agencies as well as “critical infrastructure.” Homeland Security, the agency’s parent department, defines such infrastructure as any “vital” assets to the U.S. or its economy, a broad category that could include power plants and financial institutions.
One U.S. official, speaking Thursday on condition of anonymity to discuss a matter that is under investigation, described the hack as severe and extremely damaging.
“This is looking like it’s the worst hacking case in the history of America,” the official said. “They got into everything.”
Trump had been silent on the attacks before Saturday.
Deputy White House press secretary Brian Morgenstern on Friday declined to discuss the matter, but told reporters that national security adviser Robert O’Brien had sometimes been leading multiple daily meetings with the FBI, the Department of Homeland Security and the intelligence agencies, looking for ways to mitigate the hack.
“Rest assured we have the best and brightest working hard on it each and every single day,” he said.
The Democratic leaders of four House committees given classified briefings by the administration on the hack issued a statement complaining that they “were left with more questions than answers.”
“Administration officials were unwilling to share the full scope of the breach and identities of the victims,” they said.
Pompeo, in the interview with Levin, said Russia was on the list of “folks that want to undermine our way of life, our republic, our basic democratic principles. … You see the news of the day with respect to their efforts in the cyberspace. We’ve seen this for an awfully long time, using asymmetric capabilities to try and put themselves in a place where they can impose costs on the United States.”
What makes this hacking campaign so extraordinary is its scale: 18,000 organizations were infected from March to June by malicious code that piggybacked on popular network-management software from an Austin, Texas, company called SolarWinds.
It’s going to take months to kick elite hackers out of the U.S. government networks they have been quietly rifling through since as far back as March.
Experts say there simply are not enough skilled threat-hunting teams to duly identify all the government and private-sector systems that may have been hacked. FireEye, the cybersecurity company that discovered the intrusion into U.S. agencies and was among the victims, has already tallied dozens of casualties. It’s racing to identify more.
Many federal workers — and others in the private sector — must presume that unclassified networks are teeming with spies. Agencies will be more inclined to conduct sensitive government business on Signal, WhatsApp and other encrypted smartphone apps.
If the hackers are indeed from Russia’s SVR foreign intelligence agency, as experts believe, their resistance may be tenacious.
The only way to be sure a network is clean is “to burn it down to the ground and rebuild it,” said Bruce Schneier, a prominent security expert and Harvard fellow.
Florida became the first state to acknowledge falling victim to a SolarWinds hack. Officials told The Associated Press that hackers apparently infiltrated the state’s health care administration agency and others.
SolarWinds’ customers include most Fortune 500 companies, and its U.S. government clients are rich with generals and spymasters.
