US officials on Thursday formally blamed Russia for backing one of the worst espionage hacks in recent US history and imposed sanctions designed to mete out punishments for that and other recent actions.
In a joint advisory, the National Security Agency, FBI, and Cybersecurity and Information Security Agency said that Russia’s Foreign Intelligence Service, abbreviated as the SVR, carried out the supply-chain attack on customers of the network management software from Austin, Texas-based SolarWinds.
