  • Conduct full DB patching on this Sunday for all DB servers

  • Close this ports from all of the servers (135, 139, 145)
  • Close all TCP 3389, TCP 445, TCP 135 and TCP 139 from all desktop machines even ours
  • Disable SMBv1 For customers running Windows Vista and later See Microsoft Knowledge Base Article 2696547.An alternative method for customers running Windows 8.1 or Windows Server 2012 R2 and later.
  • For client operating systems: Open Control Panel, click Programs, and then click Turn Windows features on or off. In the Windows Features window, clear the SMB1.0/CIFS File Sharing Support checkbox, and then click OK to close the window. Restart the system.
  • For server operating systems: Open Server Manager and then click the Manage menu and select Remove Roles and Features. In the Features window, clear the SMB1.0/CIFS File Sharing Support check box, and then click OK to close the window. Restart the system.
  • SMB should be disabled if not required for business use.

  • All SMB-related patches should be applied to servers as soon as practical.
  • Any Microsoft updates that haven’t been applied to servers should be applied as soon as possible.
  • Notice to all users should be sent regarding this attack and a reminder about clicking links or opening files in emails from suspicious or unknown sources should be sent.
