Microsoft SharePoint hit by major zero-day attack

Microsoft is dealing with a high-stakes security mess. A zero-day vulnerability in its on-premises SharePoint servers is under active attack, and close to 100 organizations are already affected. This isn’t theoretical. The exploit was live, unpatched, and fully weaponized before defenders could catch up.

Who’s affected?
Private companies, government bodies, and enterprise-level users, basically anyone running SharePoint Server in-house.
