The Current scenario of cyber attacks has lead to the birth of new ransomware called WannaCry. A large of people are affected over the world by this, at least 175 countries and Indians are being mostly affected. This ransomware uses a windows SMB (Server Message Block) exploit. It Infects files via sharing them on mail or FTP or some site.
The Server Message Block (SMB) protocol is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. The SMB protocol can be used on top of its TCP/IP protocol or other network protocols. Using the SMB protocol, an application (or the user of an application) can access files or other resources at a remote server. This allows applications to read, create, and update files on the remote server. It can also communicate with any server program that is set up to receive an SMB client request. Windows Server 2012 introduces the new 3.0 version of the SMB protocol.
But Hold on there’s a tool to save you from crying and make you smile. WannaSmile tools aims to disable SMB protocol and also tells you to install the current patch by Microsoft. Thanks to IndrajeetB for creating this tool. Download Link below.
