An open source implementation of SMB exists with the name of Samba , which is commonly used to easily use Linux and Windows together in a network.

Except for helpless waiting for the cure, there are some things we can do to prevent infection and make things better. It is said that the WannaCry virus infect hard drive via TCP port which opened by system during installing, so does to Petya variant virus.

Following details how to block port in Windows 7, 10, and XP in easy and simple ways. But before that, you may want to know what TCP port is used for, so is the port Port and port are Windows ports. They all serve Windows File and Printer Sharing. Keep port and port opened will leave the hard disks exposed on this port, i.

You may understand port in this way. If you close port , you will not be able to copy any file system data to or from the path where port is closed. In terms of domain host, this will definitely break group policy.

You will lose browsing capabilities to networks past the intranet network as well. Although the port is opened by system on Windows in most cases, it is necessary to check it on your host. In one or two seconds, the picture will show up. This means the TCP port is opened. Since it is one of the most dangerous ports on the Internet and made way for WannaCry attack, closing it becomes urgent.

There are three methods to disable port in Windows 10, 7 and XP in total. SMB 3. The SMB protocol supports two levels of security. The first is the share level. The server is protected at this level and each share has a password. The client computer or user has to enter the password to access data or files saved under the specific share. User level protection was later added to the SMB protocol. It is applied to individual files and each share is based on specific user access rights.

To identify the following information of Windows or Samba system, every pentester go for SMB enumeration during network penetration testing. Here you can observe, we are using nmap the most famous network scanning tool for SMB enumeration. As a result, we enumerated the following information about the target machine:. During the enumeration phase, generally, we go for banner grabbing to identify a version of running service and the host operating system.

Once you enumerate this information then you should go for vulnerability scanning phase to identify whether the install service is a vulnerable version or patched version. Nmap serves various scripts to identify a state of vulnerability for specific services, similarly, it has the inbuilt script for SMB to identify its vulnerable state for given target IP.

As result, it has shown the target machine is highly vulnerable to Ms eternal blue due to SMBv1. As we know it is vulnerable to MS and we can use Metasploit to exploit this machine. Therefore we run the following module which will directly exploit the target machine. We have successfully access remote machine shell as shown in the bellow image.
