Microsoft has alerted organizations of "active attacks" exploiting unknown vulnerabilities in its SharePoint server software, widely used for internal document sharing. The company urges immediate application of security updates, as the attacks affect on-premises servers but not SharePoint Online. Collaborating with the FBI and CISA, Microsoft addresses this "zero-day" attack, which has jeopardized tens of thousands of servers across US and international agencies. The identity of attackers remains unknown.
