The White House announces the senior official is leading an investigation into the SolarWinds hack

But damage assessment, lessons learned from Russian action and response is a slow process. Biden, aides, said he did not want the risk of further escalating tensions with Putin. And it is not yet clear whether the attack is over, or will be limited to communication theft.

After a brief meeting on the issue, Mr. Warner and Mr. Rubio wrote that “the threat our country still faces from this incident requires clear leadership to develop and guide a dominant strategy. Most recovery, especially a leader who has the authority to coordinate the response., sets priorities and directs resources where they are needed. “

Neuberger’s efforts focused on directing agencies hacked by Russian intrusion to patch and repair their networks, test the government’s response to the incident and work with Private area. She is also overseeing a study on the long-term impact of the attack on the software “supply chain”, Ms. Horne said.

The White House has also asked the Office of the Director of National Intelligence to conduct an assessment of the SolarWinds hack, which is ongoing.

Mr. Warner has pledged to hold public hearings on the intrusion to help better understand what happened.

In an interview last week, before the letter was sent, Mr Warner said he was concerned that FireEye, a leader in cybersecurity, was not a network of sensors by the Security Agency. National monitoring, has discovered intrusion SolarWinds. The agency did not say anything publicly about why those signals were missed.

“I want to be more wrong in the public discussion aspect,” Mr Warner said last week.

Dmitri Alperovitch, a cybersecurity expert who co-founded CrowdStrike and currently runs the Silverado Policy Accelerator, an advisory body, told the House Homeland Security Committee on Wednesday that the hack SolarWinds had the biggest impact of any cyberattack in US history. The attack created a clear “critical gap” in US strategy.
