At Thursday's House of Representatives Homeland Security panel, Microsoft President Brad Smith addressed tough questions about the tech giant's security measures and connections to China. The scrutiny follows a significant breach last summer when China-linked hackers accessed 60,000 US State Department emails by infiltrating Microsoft's systems. Additionally, earlier this year, Russia-linked cybercriminals spied on emails of Microsoft's senior staff, further intensifying concerns.

Lawmakers criticised Microsoft for failing to prevent these cyberattacks, which exposed federal networks to significant risk. They highlighted a report by the Cyber Safety Review Board (CSRB) that condemned Microsoft for lack of transparency regarding the China hack, labelling it preventable. Smith acknowledged the report's findings and stated that Microsoft acted on most of its recommendations. He emphasised the growing threat posed by nations like China, Russia, North Korea, and Iran, which are increasingly sophisticated and aggressive in their cyberattacks.

During the hearing, Smith defended Microsoft's role, saying that the US State Department's discovery of the hack demonstrated the collaborative nature of cybersecurity. However, Congressman Bennie Thompson expressed dissatisfaction, stressing that Microsoft is responsible for detecting such breaches. Given its substantial investments there, panel members also inquired about Microsoft's operations in China. Smith noted that the company earns around 1.5% of its revenue from China and is working to reduce its engineering presence in the country.

Despite facing significant criticism over the past year, some panel members, including Republican Congresswoman Marjorie Taylor Greene, commended Smith for accepting responsibility. In response to the CSRB's findings, Microsoft has pledged to prioritise security above all else, launching a new cybersecurity initiative in November to bolster its defences and ensure greater transparency moving forward.
