Windows Vista – Support Ends

On May 12, 2017 "WannaCry" malware began exploiting a vulnerability in most versions of Windows dating back to XP. A month earlier, Microsoft identified the risk and responded with a patch (Critical Security Bulletin MS17-010) that required rebooting after installation. Many servers and end-user pcs were left vulnerable in more than 150 countries.

The malware sneaks through SMB ports, then encrypts a user's data and presents a growing ransom demand, starting at $300 and growing to $600, after which the garbled data is lost forever without a valid external backup. Once active it spreads quickly to other PCs in the same network.

Solution: Apply Security Update patch for Microsoft Windows (4013389). A restart will be required to complete the update.

Workaround: Disable SMBv1 on client and server computers, but do not disable SMBv2 or v3. Additionally, block SMB ports (139, 445) from all externally accessible hosts. A restart will be required to complete the workaround.
