U.S. Senators: AWS Infrastructure Used In SolarWinds Attack ‘The operation we’ll be discussing today uses [Amazon’s] infrastructure, [and], at least in part, required it to be successful. Apparently they were too busy to discuss that here with us today,’ says Sen. Marco Rubio, R-Fla. By Michael Novinson February 23, 2021, 07:06 PM EST Senators slammed Amazon Web Services for refusing to testify at a hearing about the SolarWinds intrusion given the public cloud giant’s infrastructure was used in the attack. “We had extended an invitation to Amazon to participate. The operation we’ll be discussing today uses their infrastructure, [and], at least in part, required it to be successful,” Sen. Marco Rubio, R-Fla., said during a Senate Intelligence Committee hearing Tuesday. “Apparently they were too busy to discuss that here with us today, and I hope they’ll reconsider that in the future.”
