Cybersecurity incident disclosed by MICROSOFT CORP in a Form 8-K (January 2024)

Material Cybersecurity Incidents On January 12, 2024, Microsoft (the “Company” or “we”) detected that beginning in late November 2023, a nation-state associated threat actor had gained access to and exfiltrated information from a very small percentage of employee email accounts including members of our senior leadership team and employees in our cybersecurity, legal, and other functions, on the basis of preliminary analysis.

We also continue to investigate the extent of the incident. We have notified and are working with law enforcement. We are also notifying relevant regulatory authorities with respect to unauthorized access to personal information.
