Microsoft said on January 19 that a Russian state-sponsored group hacked into its corporate systems on January 12 and stole some e-mails and documents from its staffs' accounts. A Russian hacking group known in the cybersecurity industry as Nobelium, or Midnight Blizzard, used a "password spray attack" starting in November 2023 to breach a Microsoft platform, the company said. The Russian group was able to access "a very small percentage" of Microsoft corporate e-mail accounts, including members of its senior leadership team and employees in its cybersecurity, legal, and other functions, Microsoft said.
