Windows server 2016 standard 14393 metasploit free
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.

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.

Use of this information constitutes acceptance for use in an AS IS condition. There are NO warranties, implied or otherwise, with regard to this information or its use. There so many script and tools are available to connect remote machine using SMB protocol, we have already written an article for connecting SMB in multiple ways. This module serves payloads via an SMB server and provides commands to retrieve and execute the generated payloads.
Currently supports DLLs and Powershell. This will generate a link for malicious DLL file, now send this link to your target and wait for his action. As soon as the victim will run above malicious code inside the run prompt or command prompt, we will get a meterpreter session at Metasploit. This module provides an SMB service that can be used to capture the challenge-response password hashes of SMB client systems.
To exploit this, the target system must try to authenticate to this module. We had use nmap UDP and TCP port scanning command for identifying open ports and protocol and from the given image you can observe that port is open for NetBIOS network service in our local machine.
Now when the victim will try to access our share folder, therefore, he will try of connecting with us through his network IP, given below image is a proof to demonstrate that victim is connecting malicious IP: When the victim will try to access the shared folder, he will get trap into fake window security alert prompt, which will ask victims to enter his username and password for accessing shared folders.
Once again the attacker had captured NTMLv2 hash, from the given image you can see that here also the attacker has captured:. Now use john the ripper to crack the ntlmv2 hash by executing given below command. From given below image you can confirm we had successfully retrieved the password: for user: pentest by cracking ntlmv2 hash. SMB Dos attack is another most excellent method we have in our Metasploit framework. To trigger this bug, run this module as a service and forces a vulnerable client to access the IP of this system as an SMB server.
Now, when the victim will try to access the shared folder through our malicious IP, the target machine will get crushed and this attack is very effective.
This module will enumerate configured and recently used file shares. As you can observe that, here it has shown three UNC paths that have been entered in the run dialogue. Now we will use a python script that activates SMB service in our Linux machine.
This is useful in the situation where the target machine does NOT have a writeable share available. You can visit GitHub for this python script.
I copied the python code from GitHub and past it into a text file as smbserver. Since we are aware of smb service which is running in host machine
– Metasploit Wrap-Up
This module exploits a vulnerability found in Windows Object Linking and Embedding OLE allowing arbitrary code execution, publicly known as “Sandworm”. However, based on our testing, the most reliable setup is on Windows platforms running Office and Office SP2. And please keep in mind that some other setups such as using Office SP1 might be less stable, and sometimes may end up with a crash due to a failure in the CPackage::CreateTempFileName function.
Systems such as Ubuntu or an older version of Windows such /8657.txt XP work best for this because they require little configuration to get going. The PPSX file is what you should send to your target. In detail, the vulnerability has to do with how the Object Windows server 2016 standard 14393 metasploit free 2 component packager. First of all, Packager does not load the INF file directly. As an attacker, you can trick it to load your INF anyway by embedding the file path as a remote share in an OLE object.
The packager will then treat it as a type of media file, and load it with the packager! The exploit will do this loading process twice: first for a fake gif file that’s actually the payload, and the second for the INF file. In the exploit, “verb” media command type is used, and this triggers на этой странице packager! CPackage::DoVerb function. Also, “-3” is used as the fake gif file’s cmd property, and “3” is used for the INF. When the cmd is “-3”, DoVerb will bail. To display the available options, load the module within the Metasploit console and продолжить чтение the commands ‘show options’ or windows server 2016 standard 14393 metasploit free 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. Penetration testing software for offensive security teams.

Exploitability Assessment: Exploitation Less Likely. Today, we learned about EternalBlue and how to exploit it using Metasploit. One of the two zero-days is exploited-in-the-wild as well. OldGremlin, a Russian threat actor group popular for financial crime and gain, was observed targeting Russian agencies Common TTPs which could potentially be exploited by these threat actors or CVEs can be found in the detailed section.
