Windows 8 — Википедия.How to Exploit EternalBlue on Windows Server with Metasploit « Null Byte :: WonderHowTo
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 Step 2: Find a Module to Use Now that we know the target is vulnerable, we can go back to Metasploit and search for an appropriate exploit.
Type run to launch the exploit. Step 4: Verify the Target Is Compromised Again, we can verify we've compromised the system with commands like sysinfo. An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 1. An attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server. The security update addresses the vulnerability by correcting how SMBv1 handles these specially crafted requests.
