SolarWinds hack was ‘largest and most sophisticated attack’ ever – Microsoft president

A hacking campaign that used a U.S. tech company as a springboard to compromise a raft of U.S. government agencies is "the largest and most sophisticated attack the world has ever seen," Microsoft Corp President Brad Smith said. The operation, which was identified in December and that the U.S. government has said was likely orchestrated by Russia, breached software made by SolarWinds Corp, giving hackers access to thousands of companies and government offices that used its products. "I think from a software engineering perspective, it's probably fair to say that this is the largest and most sophisticated attack the world has ever seen," Smith said during an interview that aired on Sunday on the CBS program "60 Minutes."
