Microsoft contained a major SharePoint security flaw, amid fresh questions about the future of its legacy on-premises software.

It's not just data theft. A China-based hacking group is using a flaw in vulnerable SharePoint servers to deliver ransomware, Microsoft warns.

A China-based hacking group is deploying Warlock ransomware on Microsoft SharePoint servers vulnerable to widespread attacks targeting the recently patched ToolShell zero-day exploit chain.

Microsoft is issuing an emergency fix to close off a vulnerability in Microsoft’s SharePoint software that hackers have exploited to carry out widespread attacks on businesses and at least some federal agencies.

A series of cyberattacks targeting Microsoft collaboration software, specifically SharePoint, have been linked to Chinese hackers and threat actors.

Microsoft’s first patch for a major SharePoint bug failed, leading to a cyber espionage spree affecting up to 9,000 servers, with China-linked actors named among the groups exploiting it.
