Chinese Hackers Exploiting SharePoint Zero-day
Digest more
A series of cyberattacks targeting Microsoft collaboration software, specifically SharePoint, have been linked to Chinese hackers and threat actors.
The zero-day vulnerability — which was first disclosed late Saturday — has been exploited by several Chinese state-aligned groups, according to Microsoft.
Chinese hackers breached the U.S. National Nuclear Security Administration through Microsoft SharePoint, with the Energy Department confirming no sensitive information was stolen.
Microsoft said it identified 2 groups as leveraging flaws in SharePoint software; China said it firmly opposes all forms of cyberattacks.
