Particular vulnerabilities and exploits come along and make headlines with their catchy names and impressive potential for damage. EternalBlue is one of those exploits. Originally tied to the NSA, this zero-day exploited a flaw in the SMB protocol, affecting many Windows machines and wreaking havoc everywhere.

EternalBlue is an exploit most likely developed by the NSA as a former zero-day. It was released in by the Shadow Brokersa hacker group known for leaking tools and exploits used by the Equation Groupwhich has possible ties to the Tailored Access Operations unit of the NSA. SMB allows systems to share access to files, printers, and other resources on the network.

The vulnerability is allowed to occur because earlier versions of SMB contain a flaw that lets an attacker establish a null session connection via anonymous login. An attacker can then send malformed packets and ultimately execute arbitrary commands on the target. We'll be using an unpatched copy of Windows Server R2 as the target for the first section of this tutorial. An evaluation copy can be downloaded from Microsoft so that you can better follow along.

The first thing we need to do is open up the terminal and start Metasploit. Type service postgresql start to initialize the PostgreSQL proffessional, if it is not running already, followed windows 7 professional sp1 exploit free msfconsole.

Next, use the search command within Metasploit to exploitt a suitable module to use. There is an auxiliary scanner that we can run to determine if a target is vulnerable to MS It's always a good idea to perform the necessary recon like this.

Otherwise, you could end up wasting a lot windows 7 professional sp1 exploit free time if the target isn't even vulnerable. Once we have determined that our target is indeed vulnerable to EternalBlue, we can use the following exploit module from the search we just did. That should be everything, so the only thing left to do is launch the exploit. Use the run command to fire it off. We see a few things happen here, like the SMB connection being established and the exploit packet being sent.

At last, we see a "WIN" and a Meterpreter session is opened. Sometimes, this exploit will not complete successfully the first time, so if it prifessional just try again and it should go through. We can verify we have compromised the target by running commands such as sysinfo to obtain provessional system information. This exploit doesn't work very well on newer systems, and in some cases, it explooit crash the target machine.

Next, we will explore a similar exploit that is a little more reliable, but just as deadly. As if EternalBlue wasn't devastating enough, three more similar exploits were developed after it. These were exlpoit into a single Metasploit module that also uses the classic psexec payload.

It's considered more reliable than EternalBlue, less likely to crash the target, and works on all recent unpatched versions of Windows, up to Server and Windows The only caveat is this exploit requires a named pipe.

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 windowa 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 sp 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, windows 7 professional sp1 exploit free, and even though the consequences exxploit 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 cryptocurrencyis another threat windows 7 professional sp1 exploit free 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.

What Is Windows 7 professional sp1 exploit free Option 1: Exploit EternalBlue with Metasploit We'll be using an unpatched copy of Windows Server R2 windows 7 professional sp1 exploit free 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 fdee Module We can take windows 7 professional sp1 exploit free look at the current windows 7 professional sp1 exploit free 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. Subscribe Now. Share Your Thoughts Click to share your thoughts. Hot Latest.
