Msfvenom Tutorials for Beginners

Hello friends!!

Today we will learn to create payloads from a popular tool known as metasploit, we will explore various option available within the tool to create payloads with different extensions and techniques.

Msfvenom

Msfvenom is a command line instance of Metasploit that is used to generate and output all of the various types of shell code that are available in Metasploit.

Requirements:

  • Kali Linux
  • Windows Machine
  • Android Phone
  • Linux Machine

Abbreviations:

Lhost= (IP of Kali)

Lport= (any port you wish to assign to the listener)

P= (Payload I.e. Windows, android, PHP etc.)

F= file extension (i.e. windows=exe, android=apk etc.)

Let’s Begin!!

From the Kali terminal type command msfvenom as shown below. It will show you all available options for creating a payload but in this article we are talking about different types of payload we can generate.

Bind shell

A bind shell is the kind that opens up a new service on the target machine, and requires the attacker to connect to it in order to get a session

Now type the below “command” on your kali terminal

It will save the “exe” payload file on your desktop as specified on the command /root/Desktop/bind.exe We need to send this file to the victim machine through file share or by any social engineering technique and have it run on the system

Now let us start msfconsole and type below command to get session of victim machine

Once the file is executed on the machine we will get the victim machine meterpreter session as show below:

The bind_tcp option is helpful in case we get disconnected from victim machine while it is still running, we can execute the same command and get back the session without any intervention of the victim to run the exploit again.

Reverse TCP Payload

A reverse shell (also known as a connect-back) is the exact opposite: it requires the attacker to set up a listener first on his box, the target machine acts as a client connecting to that listener, and then finally the attacker receives the shell.

From the Kali terminal type command msfvenom as shown below:

Now type command

In this case we will include few other options such as lhost (local host) and lport (local port) to get a reverse connection from the victim machine

Once the payload is generated and send to the victim for execution, we will start our next step as shown below

Now let us start msfconsole and type below command to get session of victim machine

We can confirm from the image below, once the payload is executed by the victim, we received a reverse connection and got the meterpreter session successfully.

HTTPS Payload

Note: Both the above payloads can be used in case we have relevant ports active on the victim machine, so the question arises what if the victim has blocked all the ports?

Well in such cases we can create payloads as per the ports running on victim machine such as 443 for https:

Let’s us use this case and create a payload with https   From the Kali terminal type command msfvenom as shown below:

Now type command

Once the payload is generated and send to the victim for execution, we will start our next step as shown below

Now let us start msfconsole and type below command to get session of victim machine

We can confirm from the above image, once the payload is executed by the victim, we received a reverse connection and got the meterpreter session.

Hidden Bind TCP Payload

Let us now explore some other technique available in msfvenom Tool and try to exploit the victim machine, this time we will get the shell of the victim machine instead of meterpreter session

Let’s begin!!

This payload hides on the background silently, while executed and does not reveal its presence if scanned by any port scanner.

From the Kali terminal type command msfvenom as shown below:

Once the payload is generated and send to the victim for execution, we will start our next step as shown below.

We use Netcat to setup our listener.

Now from the kali Terminal let us type the command as shown above

Reverse Shell Payload with Netcat

Let us now do the same process and use shell_reverse_tcp payload, one more technique to get shell session of the victim

From the Kali terminal type command msfvenom as shown below:

Once the payload is generated and send to the victim for execution, we will start our next step as shown below

We setup our listener using netcat, the image below confirms the shell session capture by the kali machine.

Now from the kali Terminal let us type the command as shown below.

Macro Payload

Let us now create a payload with a Vba script, which we will use to create a macro on Excel to exploit victim machine.

Let us begin to create the payload!!

Open Kali Terminal and type command as mention below:

once the command is executed copy the script starting from “#if vba 7 till “End if” as highlighted in below image:

Let us now open an excel file and press alt+F11 key to open VB script, you will get the option box as shown above, enter the name you will like to provide and click on “create”.

You will get a new option box as above, click on “This workbook” and replace the values with your copied vb script payload generated by msfvenom tool and close the vb script editor and enable the macro.

Now you may draft your excel file with relevant data which may look realistic for an victim to open the file, in our case we have just inserted the value “Test”  save the file and send it to the victim.

To capture the sessions let us now start the multi handler as stated below:

Open kali Terminal and type msfconsole

Once the excel file is opened by the victim, it will prompt the victim to enable the macro, once enabled, our vbscript will get executed to provide us with reverse connection to the victim machine as show in the below image.

VNC Payload

Will it not be great if we can take the remote of victim machine without their knowledge and observe their activity anonymously,  this payload does exactly that , let us use it to our benefit.

Let us begin to create the payload!! Open Kali Terminal and type command as mention below:

Once the payload is generated and send to the victim for execution, we will start our next step as shown below. To capture the sessions let us now start the multi handler as stated below:

Open kali Terminal and type msfconsole

We can see that reverse connection has executed the VNC injection and the victim remote machine session is established on our kali machine showing Remote Desktop.

Android Payload

Exploiting handheld devices have always been as hot topic and still continues, hence we have included it in our article as well, let us use one of the android exploit available within the msfvenom tool and use it to our benefit.

Let’s begin

Open Kali Terminal and type command as mention below:

Once the payload gets generated send it to the victim to execute on his handheld, and start multi handler as shown in below image.

Once the payload gets executed, you will get the meterpreter session of the handheld, which is now in your control as shown below.

Linux Payload

Open Kali Terminal and type command as mention below:

Once the payload gets generated send it to the victim to execute on his Linux machine and start multi handler as shown in below image.

Once the payload gets executed, it will create a reverse tcp connection on our kali machine providing us with meterpreter sessions, as shown on the image below.

Powershell Payload

Open Kali Terminal and type command as mention below:

Once the payload gets generated send it to the victim to execute on his windows machine and start multi handler as shown in below image.

Once the payload gets executed, it will create a reverse connection to shell as shown in the image below.

    Hello
    Thank you for the amazing post

    I tried all your technique in my lab.

    the payload gets created and it also runs
    but i don’t get the reverse connection back. my console displays
    *started revere TCP handler on 10.0.0.1:4444
    and courser keeps on blinking

    the payload gets executed and run

    Thanks for this useful information
    I just have a doubt when we inject the payload in victims computer we can access their details at that instance of time what if we can access it after some other time may be one or days later
