You’ve seen the news about Ransomware attacks. The latest battle is won but the war is not over. And Magento users be aware there is an attack that targets your store.
Upgrade to Windows 10 and Turn On Windows Update
If you are running an older version of Windows upgrade right now. Then be sure Windows Update is turned on (it is by default). The easiest way to do that is to click on the Cortana icon (the circle next to the Windows start icon) and type “Windows Update”. Click the Advanced Settings link and in the settings that open make sure updates are not deferred (set to 0) and Pause is Off.
Turn off SMBv1
In Windows 10 click the Cortana icon and type “Turn Windows features on or off”. In the dialog that opens uncheck the box for SMB 1.0/CIFS File Sharing Support. Close the dialog and when prompted restart your PC. Note: You can turn off this protocol in Windows 7 and 8 as well by opening Control Panel and clicking Programs then the Windows on/off option, but you are still otherwise unprotected until you upgrade to Windows 10.
