First, let me just say I am completely new to pen testing and such but I am a veteran tech and I want to learn more. I recently got something in the mail that was a promotion for a new TV series. Attached to the side of a fake old 5 1/4 in floppy I noticed a USB edge connector. Printed on the side it read "Insert this into your computer to watch the first full episode now!". I thought for sure that they wouldn't give out a video on a thumb drive so I checked it out. When I plugged it in, it acted a lot like the Rubber Ducky I've seen on Hak5 (a clever bit of marketing I must say). I'm sure that it was coded as a HID because I saw it rapidly open the "Run" box then type a URL to go to it's website and then I assume hit OK or enter to execute it. My question is, can I modify this device to make it more like a Ducky? What tools would I use to explore/modify it's contents?
Thanks in advance, I love this forum.
