Ddoor - Cross Platform Backdoor Using Dns Txt Records

Cross platform backdoor using dns txt records.

What is ddor?

ddor is a cross platform light weight backdoor that uses txt records to execute commands on infected machines.

Features

  • Allows a single txt record to have seperate commands for both linux and windows machines
  • List of around 10 public DNS servers that it randomly chooses from
  • Unpredictable call back times
  • Encrypts txt record using xor with custom password

Linux Features:

  • Anti-Debugging, if ptrace is detected as being attached to the process it will exit.
  • Process Name/Thread names are cloaked, a fake name overwrites all of the system arguments and file name to make it seem like a legitimate program.
  • Automatically Daemonizes
  • Tries to set GUID/UID to 0 (root)

Windows Features:

  • Hides Console Window
  • Stub Size of around 20kb

Installation

To install the dependencies needed for the python generation script run.

pip3 install -r requirements.txt

Make sure to edit config.h and replace the provided domain with yours, you can change the fake name as well as the password.

To create a Linux binary:

Run the compile.sh script, this will create a file called binary in the bin folder.

To Create a Windows Binary:

This project was built using VS 2019, if you open the sln file using VS2019 select the release build and build it.

Usage

Run payload_manager.py with python3 to create a hex encoded payload, then update or create a txt record for your domain, make sure that the TTL is set to 300 seconds!!!

Payload Manager Usage:

$ ./payload_manager.py -h
