Summary: Microsoft issued security updates for unsupported Windows versions including Windows XP, Windows 8, and Windows Server 2003 to slow the spread of the WanaCrypt ransomware that began hitting organizations worldwide on Friday, May 12, 2017. The worm spread through a Windows file-sharing vulnerability Microsoft had patched in March 2017, but older unsupported systems could not apply that fix, and at least 16 UK hospitals diverted emergency patients after infection while Avast reported more than 100,000 detections.
