Microsoft has enhanced its cybersecurity posture following a major breach attributed to China-backed threat actors, known as Storm-0558. Key improvements include migrating Microsoft Account (MSA) sign-ins to Azure confidential virtual machines (VMs) to bolster security. The company reports that 92% of its staff now utilize phishing-resistant multi-factor authentication (MFA), and 81% of its code branches are protected with proof-of-presence technology. Additionally, Microsoft introduced Quick Machine Recovery, a new feature that automatically fixes Windows boot failures. These measures are part of the Secure Future Initiative (SFI), described by Microsoft as the largest engineering project in its history, aimed at transforming cybersecurity across its systems and products. Industry observers note tangible progress in Microsoft's security culture and its efforts to safeguard both internal systems and customer services. Concurrently, broader cybersecurity trends highlight that one in three organizations worldwide have adapted their security architectures to counter AI-driven threats, emphasizing the growing importance of resilient cyber defenses in the evolving threat landscape.
