In the Wake of Recent Mass Scale Ransomware Attacks Globally



In the wake of recent mass scale ransomware attacks globally, Microsoft has released a security bulletin for Windows OS and has released some patches also. But mostly it is being observed that to attack and Windows OS, the SMB1.0/CIFS File Sharing exploit is being used. The simplest prevention would be to disable the SMB1.0/CIFS File Sharing Feature from Windows OS itself. The procedure would be:

For client operating systems:


  1. Open Control Panel, click Programs, and then click Turn Windows features on or off.
  2. In the Windows Features window, clear the SMB1.0/CIFS File Sharing Support checkbox, and then click OK to close the window.
  3. Restart the system.


For server operating systems:


  1. Open Server Manager and then click the Manage menu and select Remove Roles and Features.
  2. In the Features window, clear the SMB1.0/CIFS File Sharing Support check box, and then click OK to close the window.
  3. Restart the system.
