Congressman Thompson concerned top government supplier Microsoft vulnerable to Chinese threat

House Homeland Security Committee Ranking Democrat Bennie Thompson says opening a hearing with Microsoft President Brad Smith about the company's cybersecurity failures that Microsoft, as one of the world's largest technology suppliers with an estimated 85 percent market share in federal government productivity software and significant cloud service provision, holds a crucial position in the nation's digital infrastructure, which comes with a heightened responsibility to cooperate fully with government reviews of security breaches, particularly in light of the recent Chinese threat actor's exploitation of vulnerabilities in Microsoft products to access sensitive information, emphasizing the company's obligation to transparency and collaboration given its substantial footprint in federal networks and the considerable portion of its government revenue derived from non-competitive contracts.
