Microsoft says state-sponsored Russian hacking group accessed email accounts of senior leaders
(CNN) — A Russian hacking group gained access to some email accounts of Microsoft senior leaders, the software giant disclosed in a regulatory filing Friday afternoon.
Posted — Updated“The Microsoft security team detected a nation-state attack on our corporate systems on January 12, 2024, and immediately activated our response process to investigate, disrupt malicious activity, mitigate the attack, and deny the threat actor further access,” the company said in a blog post. “Microsoft has identified the threat actor as Midnight Blizzard, the Russian state-sponsored actor also known as Nobelium.”
Hackers were able to gain access to “a very small percentage of Microsoft corporate email accounts,” the blog post added, including accounts belonging to members of its senior leadership team and employees in its cybersecurity and legal departments.
The attack began in late November 2023.
The attack was not the result of a vulnerability in Microsoft products or services, the blog post adds.
