Microsoft says state-backed Russian hackers accessed emails of senior leadership team members

Microsoft says state-backed Russian hackers broke into its corporate email system and accessed accounts of members of the company’s leadership team, as well as those of cybersecurity and legal employees. In a blog post Friday, Microsoft said the intrusion began in late November and was discovered Jan. 12. The company says a very small percentage of Microsoft corporate accounts were accessed and some emails and documents were stolen. A Microsoft spokesperson had no immediate comment on which or how many members of the company's senior leadership had their email accounts breached.
