Microsoft Says Chinese Hackers Exploiting SharePoint Flaws

Microsoft Corp. accused Chinese state-sponsored hackers of using flaws in its SharePoint document management software in a hacking campaign that has targeted businesses and government agencies around the world.

In a blog post on Tuesday, the tech giant identified two groups supported by the Chinese government, Linen Typhoon and Violet Typhoon, as leveraging flaws in SharePoint software used by customers who managed it on their own networks, as opposed to in the cloud. Another hacking group based in China, which Microsoft calls Storm-2603, also exploited the SharePoint vulnerabilities, according to the blog.
