Microsoft ‘Bears Responsibility’ For China-Tied Hacks, Senator Says

In a scathing letter sent to key federal agencies, Senator Ron Wyden called for multiple investigations of Microsoft Corp. over a breach of US officials email accounts by China-linked hackers.

Wyden’s letter — sent to heads of the Cybersecurity and Infrastructure Security Agency, Department of Justice and Federal Trade Commission — said that Microsoft “bears significant responsibility for this new incident.” The senator also chided the company for its role in the SolarWinds attack, disclosed in 2020, when Russian hackers compromised computer networks in the federal government and private sector.
