The tools you will need 1. Nmap:- This is for generating a list of server ips, which is using the default RDP port 3389. 2. DUBrute:- This is for the cracking, using the list of ips you generated with nmap. Generating the list of ips:- To start using this guide, you have to make sure that you got the tools from the last section. Now to start generating the list of ips you will use nmap. To do so is really simple, you simply open up the Scanner.bat file and wait a few minutes/hours(depending on the amount of ips you need). All of the servers which has the port 3389 open, will be located in the Results.tx file When this pops up you can minimize it and let it run in the background. Creating our combo file Now when we have our file containing a lot of ips, lets move on to the combo file creation. This file will be compiled using a username file, a password file and the ip file. First lets open up DUBrute.exe Here we will use the ***8220;Generation***8221; option in DUBrute to compile our combo file. So click on the ***8220;Generation***8221; button to the right Now click the ***8220;File IP***8221; button under the IP section and choose your results file, from nmap. Now when the ip list is imported, we can go to the next file, which is the login/username file. This file will be located in the same folder, as DUBrute.exe. Starting the cracking process:- Now when you have your combo file, everything is ready. Go back to your DUBrute main window, and hit the ***8220;config***8221; button. Under the source you will select your combo file and under bad, good and error just leave it as it is. You can use the settings i use for threads, try connection, timeout and autosave, but you can find information about these on the internet. Hit the ***8220;Ok***8221; button and then hit the ***8220;Start***8221; button in the main window. Your computer is now cracking RDP servers and if it finds any matching username:password, it will be located in the good.txt file. You can easily these two software on net. I wanted to give you link but found virus in it. So better you find yourself. Hope you will find it useful. Thanks for watching my thread.
