1- You need a good I.P. Scanner; Here's KPortScan-3.0 which will get the job done.

Now, you need IP's.
Go to this Website: https://www.countryipblocks.net/country_selection.php

Then Select the Country you want the RDP's to be from

Next, Save the IP ranges and import them into KPORT that you downloaded earlier

Import IP's, do not mess with default settings and click start!
When it's done, it will spit out a .txt file with all the IP's
Now, that we have that juicy juicy IP list, we need to start the brute process.
For this; We're going to use DUBrute

Run DUBRUTE and follow the steps in the following images:

Next, Import your IP List from KPORT

You're almost ready; if you're not satisfied with the preexisting common password list that is provided, simply find one off the forums.
Before starting, make sure you edit your settings in CONFIG of DEBRUTE; if you have 2GB ram, set the Threads to 100, if you have 4GB
ram, Set the threads to 200; ect.

For the Usernames in Debrute Use the following generic common logins:
administrator
admin
admin1
user
user1
user2
test
test1
test2
remote
server
manager
root
support
scanner
scan
temp
For passwords use this common password list: https://throwbin.io/6IsoAzQ
Now just click START and good luck!
The successful cracks will be in a .txt in the same folder
DO NOT CHANGE THE PASSWORD ON THE RDP
it will get changed and you will lose access, simply create a new account!
You could sell these or run other stuff off them https://txgate.io/images/smilies/smile.gif
