SolarWinds, Microsoft, FireEye, CrowdStrike defend actions in major hack: US Senate hearing

Top executives at Texas-based software company SolarWinds Corp, Microsoft Corp and cybersecurity firms FireEye Inc and CrowdStrike Holdings Inc defended their conduct in breaches blamed on Russian hackers and sought to shift responsibility elsewhere in testimony to a U.S. Senate panel.
One of the worst hacks yet discovered had an impact on all four. SolarWinds and Microsoft programs were used to attack others and the hack struck at about 100 U.S. companies and nine federal agencies.
Lawmakers started the hearing by criticizing Amazon representatives, who they said were invited to testify and whose servers were used to launch the cyberattack, for declining to attend the hearing.
“I think they have an obligation to cooperate with this inquiry, and I hope they will voluntarily do so,” said Senator Susan Collins, a Republican. “If they don’t, I think we should look at next steps.”
