[Question] Executable issues with the ducky

[Vallandingman]

Hey guys,

I've gotten everything to work fine and I understand how the duck works. The only issue I have is that the only way I can get my payloads to run is when I click the button on the duck encoder. The program wont run just by plugging the duck in. Thoughts on how to fix this? Thanks!

Re-flashing the ducky might work. Do you have any special firmware installed?

[Vallandingman]

I downloaded the firmware and placed it in the micro SD card(1G) along with the ducky encoder. Other than that, it's just my helloworld.txt file and the inject.bin that I created through MS powershell.

It sounds like you didn't go through the flashing process, so you sill have the stock firmware. Post the helloworld.txt file here so we can see it, there might be something there. Also, make sure you are using the encoder correctly. Typically the inject.bin is not created in power shell, but is created in the command line.

example of command:

J:\> java -jar J:\Encoder_V1.2\duckencode.jar -i J:\HelloWorldFolder\HelloWorld.txt -o J:\inject.bin

Also, make sure the inject.bin is on the root of the SD card.

Sorry this sort of confused me. Power shell is the command line application I'm using.

Also, what is the flashing process I need to go through?

Says I currently can't upload the text file, but here is what is in it..

REM Author: -

REM Description: Hello World

STRING Hello World

ENTER

Thanks so much for the input!

[overwraith]

Ok, I just tried to use power shell, and you're right, its just like the command line, and should work for our purposes. We are going to change the hello world you are using so we can actually see the output in a text program, so here's the hello world program I put on the duck site.

DELAY 3000
GUI R
DELAY 500
STRING notepad
DELAY 500
ENTER
DELAY 750
STRING Hello World!!!
ENTER

For now don't even bother with trying to flash the ducky, it isn't strictly required for learning purposes.

The following is what I would type into Power shell assuming that both the encoder, and the hello world text document are both on the root of the drive:

Windows PowerShell

PS C:\Users\UserName> J:
PS J:\> java -jar encoder.jar -i HelloWorld.txt
PS J:\>

 

[Vallandingman]

Okay I changed the hello world text, changed the PS script to fit the drive (K:)

My PS script was

PS C:\> K:

PS K:\> java -jar encoder.jar -i helloworld.txt

I got an error that states,

> Error: Unable to access jarfile encoder.jar

Here is a picture for better reference.

[Vallandingman]

I believe since you named yours 'encoder' is why it didn't work. I should place 'duckencode.jar' instead, right?

[overwraith]

yes, replace with duckencode .jar the name of the encoder changed between versions 1.2 and 2.1.

Awesome, it worked!! I think it may have been something I was doing wrong with my -o command. Thank you so much again!

[overwraith]

Good, and remember, the -o command is optional, if the encoder and text file is located on the root of the flash drive you don't even need to type it.
