The attacker can then use various Meterpreter commands to interact with the victim machine, such as gathering system information, running commands, or executing code on the victim machine. Once the exploit is successfully executed on the victim machine, the Meterpreter payload will establish a reverse TCP shell connection back to the attacker's machine on the specified LHOST and LPORT. Set the LPORT parameter to the port number that the attacker wants to listen on for incoming connections: set LPORT 4444 set payload windows/meterpreter/reverse_tcp Set the LHOST parameter to the IP address of the attacker's machine. We can get to know which options are required with the help of the command "show options". Before we launch the attack, we have to set them. The selected exploit may require some values as parameters. Threfore, once the exploit is successfully executed on the victim machine, the Meterpreter payload will establish a reverse TCP shell connection back to the attacker's machine on the specified LHOST and LPORT. In our case we are going to use meterpreter as our payload. The victim machine connects to the attacker machine via this connection details. LPORT and LHOST are parameters used in the reverse TCP connection to specify the listening port and listening host respectively. Therefore in our tutorial, we are going to use the meterpreter as the payload of our attack. For example, it provides a command shell with many built-in commands, as well as the ability to spawn additional sessions, migrate to different processes, and evade detection by antivirus software. Meterpreter has several features that make it popular with penetration testers and attackers. There are various functions such as capturing screenshots, stealing passwords, manipulating files, and pivoting to other systems on the network. It is a powerful payload that can be delivered as part of an exploit to gain remote access and control over the compromised system. "Meterpreter" is a post-exploitation tool that is part of the Metasploit Framework. The multi-handler will maintain a list of all active sessions and provide an interface for the attacker to switch between sessions or interact with multiple sessions at the same time. When a victim machine connects to the multi-handler, the Metasploit framework will automatically assign a session ID to the connection and the attacker can use various Meterpreter commands to interact with the victim machine. Once the attacker has set up the multi-handler, any victim machines that execute the reverse TCP payload will establish a connection with the attacker's machine. The multi-handler is typically used in conjunction with a payload that establishes a reverse connection to the attacker's machine, such as windows/meterpreter/reverse_tcp. The Metasploit multi-handler is an exploit module in Metasploit that allows an attacker to handle multiple connections from different payloads that are executed on multiple victim machines. In a bind shell scenario, the victim computer is listening on a specific port, and the attacker connects to it, while in a reverse TCP shell scenario, the attacker is listening on a specific port, and the victim computer initiates the connection. The main difference between a bind shell and a reverse TCP shell is the direction of the connection. The attacker connects to the victim's system by running a client program that connects to the listening port. The listening program is running on a specific port on the victim's system. That listener is waiting for an incoming connection from the attacker. In this type of attack, the attacker sets up a listening program on a victim's machine. Since the connection is from the victim side to the attacker side it is called a revere shell.Ī bind shell is another type of shell that allows a remote user to access and control a computer system over the network. That shell can be used to gain control over the victim machine. When the lister receives the TCP connection, it serves as a shell to access the victim server. Therefore it is also known as the lister. The attacker's machine is waiting for an incoming connection from the victim. In a reverse shell, we open a connection from the victim server to the attacker's machine. In both of these situations, there is an Attacker mashing and a victim server. Reverse TCP vs Bind TCP shellįirst of all, let's clarify what is a reverse TCP shell, What is a bind shell and how they work. It can create a reverse TCP connection to our mashing. For example, we use msfvenom to create a web shell in PHP and use Metasploit to get the session. So in today's tutorial, we are going to see how we can build a reverse TCP shell with Metasploit. I hope to start a tutorial series on the Metasploit framework and its partner programs. It can automate the exploitation process, generate shellcodes, use it as a listener, etc.
