Security vulnerabilities exploited in servers hosting document-sharing software used by many large businesses
Microsoft says Chinese “threat actors”, including state-sponsored hackers, have exploited security vulnerabilities in its SharePoint document-sharing software servers and are targeting the data of businesses that use it.
The US technology company said it had observed three groups – the Chinese state-backed Linen Typhoon and Violet Typhoon, and Storm-2603, which is believed to be China-based – using “newly disclosed security vulnerabilities” to target internet-facing servers hosting the platform.
