Russian-backed Hackers Breach Microsoft Corporate Emails

Microsoft disclosed that some of its corporate email accounts were breached by a Russian-backed group known as Midnight Blizzard, which gained access to a small percentage of email accounts, including those of senior leadership and cybersecurity personnel. The hackers exfiltrated some emails and documents before their access was removed by Microsoft. The company stated that there is no evidence of access to customer environments, production systems, source code, or AI systems, and it is in the process of informing affected users while the investigation continues.
