Congressman Thompson remarks at hearing on Chinese hack of State Department email

House Homeland Security Committee Ranking Democrat Bennie Thompson says opening a hearing with Microsoft President Brad Smith about the company's cybersecurity failures that the discovery of a Chinese state-sponsored threat actor's infiltration of high-ranking US officials' email accounts, including those at the Departments of State and Commerce and a member of Congress, using a stolen key from 2016 to forge tokens, has prompted Secretary Mayorkas to initiate a Cyber Safety Review Board (CSRB) investigation into the Microsoft Exchange Online intrusion and targeted attacks on cloud environments, noting that the CSRB conducted a thorough and expeditious review, resulting in a report that exemplifies the kind of comprehensive analysis only the government can perform, providing crucial insights into the nature and extent of the cyber threat.
