Russian State-Backed Hackers Target Microsoft's Core Systems

Microsoft detected a cyberattack by a Russian state-backed group, Midnight Blizzard, in January, which gained access to the company's core software systems and source code repositories. The hackers used information from corporate email systems to attempt unauthorized access, but Microsoft found no evidence of compromise to customer-facing systems. The attack, which began in November, has not materially impacted Microsoft's operations, and the company is working to enhance security measures and assist affected customers.
