lookup "badusb". there was some research done a few years ago where you could actually run small programs on the flash drives' CPU. A specific version of Phison controllers. you could do some simple things like dump sections of memory IIRC.

It was hosted on GitHub I think and "Phison" was in the name. If you cant find I should be able to get more details.

There was a Blackhat and/or Defcon talk along with whitepaper.

cool as hell, wish I had more time to play around with stuff like that

Thanks Franc, so it is. The info I was taking about is referenced as such

However, soon after, two other researchers (Adam Caudill and Brandon Wilson) presented to the whole world at Derbycon conference an operable PoC tailored to Phison 2251-03 microcontroller The code is available at GitHub.

Actually I have seen this as well... I went to save it and seems files already exist. My file hoarding is overtaking my memory...

I didn't visit the link as I associate USB Rubber Ducky with Hak5's product, and this isn't an actual USB flash drive.

This new paper has a good overview of the several possible ways to get access to the firmware of flash devices:

I also wrote about how I got access to firmware:
