White House 'Stands Down' SolarWinds, Exchange Response Groups Twitter Deputy National Security Adviser Anne Neuberger (Source: C-SPAN) The White House announced Monday that it is "standing down" two Unified Coordination Groups that were created to coordinate the federal response to the SolarWinds supply chain attack and attacks on vulnerable on-premises Microsoft Exchange email servers. Anne Neuberger, the deputy national security adviser for cyber and emerging technology who's overseeing the Biden administration's response to the attacks, says the two groups' work can be scaled back because of increases in patching and other mitigation by federal agencies and companies. "Due to the vastly increased patching and reduction in victims, we are standing down the current [Unified Coordination Group] surge efforts and will be handling further responses through standard incident management procedures," Neuberger says.
