  PDF Writer 2. Didn't match my screen. After some failed attempts to get favicon. At last, we see a "WIN" and a Meterpreter session is opened. As of Feb - this module does not support SMB 1. See Microsoft Knowledge Base article

This bulletin includes a patch which prevents the relaying of challenge keys back to the host which issued them, preventing this exploit from working in the default configuration. It is still possible to set the SMBHOST parameter to a third-party host that the victim is authorized to access, but the "reflection" attack has been effectively broken. As of Feb - this module does not support SMB 1. To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':.

Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters. Description This module will relay SMB authentication requests to another host, gaining access to an authenticated SMB session if successful.

Penetration testing software for offensive security teams. Named pipes provide a method for running processes to communicate with one another, usually appearing as a file for other processes to attach to. The Metasploit module automatically checks for named pipes, making it pretty straightforward to use as long as a named pipe is present on the target.

We can use Nmap as an alternative to the Metasploit scanner to discover if a target is vulnerable to EternalBlue. The Nmap Scripting Engine is a powerful feature of the core tool that allows all kinds of scripts to run against a target.

Here, we'll be using the smb-vuln-ms script to check for the vulnerability. Our target will be an unpatched copy of Windows Server Datacenter edition. Evaluation copies can be downloaded from Microsoft so you can follow along if you want. We can specify a single script to run with the --script option, along with the -v flag for verbosity and our target's IP address. First, change directories in case you're still running Metasploit.

Nmap will start running and shouldn't take too long since we are only running one script. At the bottom of the output, we'll find the results. We can see it lists the target as vulnerable, along with additional information like risk factors and links to the CVE.

Now that we know the target is vulnerable, we can go back to Metasploit and search for an appropriate exploit. It looks like this exploit uses a list of named pipes to check and connects to a share. We can leave all this as default for now, but we need to set the remote host. Despite all the damage EternalBlue has caused, there is one reliable way to prevent these types of exploits: patch your systems! At this point, nearly two years since these vulnerabilities were disclosed, there is really no excuse to have unpatched operating systems.

EternalBlue continues to be a problem, though, and even though the consequences are dire, unfortunately, some organizations will still be running unpatched systems. That, combined with pirated versions of Windows, makes EternalBlue a significant threat to this day. Cryptojacking, which uses a victim's computer to secretly mine cryptocurrency , is another threat vector that uses EternalBlue to leverage attacks.

WannaMine was one of these outbreaks that hijacked computers around the world in Today, we learned about EternalBlue and how to exploit it using Metasploit. We also learned about an exploit similar to EB that is more reliable and works on more systems.

In the next tutorial, we will dig a little deeper and learn how to exploit EternalBlue manually, which is much more satisfying in the end. Want to start making money as a white hat hacker?

What Is EternalBlue? Option 1: Exploit EternalBlue with Metasploit We'll be using an unpatched copy of Windows Server R2 as the target for the first section of this tutorial.

Step 1: Find a Module to Use The first thing we need to do is open up the terminal and start Metasploit. Step 2: Run the Module We can take a look at the current settings with the options command.

Step 3: Verify the Target Is Compromised We can verify we have compromised the target by running commands such as sysinfo to obtain operating system information. Starting Nmap 7. NSE: Script Pre-scanning. Initiating NSE at
