Let us now do the same process and use shell_reverse_tcp payload, one more technique to get shell session of the victim. Victim's machine acts as a client and initiates a connection to the attacker's listening server. For example, a reverse shell is a payload that creates a connection from the target machine back to the attacker as a Windows command prompt, whereas a bind shell is a payload that “binds” a command prompt to a listening port on the target machine, which the attacker can then connect. This is most likely everybody’s first choice. This will start the listener on the port 5555. Now, we will open a victim's shell on our base system to which victim will connect back using the reverse_bind_shell payload.
