The White House is in “the closing stages” of deciding how to respond to a hack that compromised popular software by Texas-based SolarWinds Corp., according to Jake Sullivan, President Joe Biden’s national security adviser.

Sullivan said the U.S. is considering “seen and unseen” responses to the attack, suspected of being carried out by Russian hackers and affecting at least 100 U.S. companies and nine federal agencies.
