BadUSB: What you can do about undetectable malware on a flash drive | PCWorld

The thesis I presented for my diploma was about physical security, with BadUSB devices taking the most amount of pages. This works thanks to the existence of a class of USB devices called HID, Human Interface Devices, a class including devices we use open hardware badusb query a daily basis, such as gaming controllers, mouses, and of course, keyboards. A BadUSB works by identifying itself as a keyboard to open hardware badusb query computer open hardware badusb query connected, so the operating system will interpret the data sent by the device as key presses.

As you can easily guess from the possible uses of these open hardware badusb query they can be a very helpful resource to any security professional, so open hardware badusb query gained quite some attention in little time, and as a result several ad-hoc easily programmable BadUSB sticks were released, such as the Malduino or the most popular model of all, the Rubber Ducky.

First of all we need to download the Arduino IDE from this link, install it, and open it. This URL will tell our IDE where to look for the packages and plug-ins related to our board, in our case, it will point to all products made by Digistump. Be careful, always double check the board type before loading any script on your board or you might brick it!

This is a direct link to the latest version of the drivers, unzip the folder inside the archive open hardware badusb query open one of these two executables to install the 32 or 64 bits version of the drivers:.

Now for the final step, open the Windows Device Manager. After this, you can click on Next and after a few seconds our board will be fully open hardware badusb query on our computer and ready to use. This is perfectly normal. To test if everything works as expected, unplug the board and load one of the examples for the Digispark, click on Open hardware badusb query and after a quick error check it will ask you to connect the board, do so and the program will be loaded in memory, if you followed all steps correctly the program should start running immediately, use a simple LED blink example and it should work fine.

Now we can start talking about serious business. And to clear one detail up, yes, in the example above you need a direct link to your script somewhere, if you happen to be in the same LAN as the victim or if you have a VPS or a computer that can be reached over WAN with its own IP then you can use PHP like so:. We use -S 0. If you fancy any more pre-made scripts to study from or to use straight away CedArctic wrote some very interesting ones and you can find them here.

Not natively, but CedArctic comes to our rescue once again with his beautiful digiQuacka tool Open Hardware Badusb Library that converts scripts written in Ducky Script into scripts we can load on the Digispark. We can observe immediately the different approach used by this program: incapsulating the entire payload inside the setup function to make it execute only once instead of putting it into loop like we did, in fact, the setup function in an Arduino sketch contains the very first instructions to be executed by the controller, while loop is called as soon as setup finishes its course, and usually contains the actual body of the program, which, as the name suggests, is executed in an infinite loop.

And this is all I had to say for today, aside from the fact that if you wish to write scripts for other keyboard layouts you will have to edit the hardcoded numbers contained in DigiKeyboard. Rubber Ducky scripts: here Digispark scripts: here. Nice read! I know that this is basically just a PoC but is there any possibility to make these keystrokes quicker and the BadUSB more stealthier?

Or am I wrong? Oh, and is it possible to install a file system on open hardware badusb query micro controller, which will be served after the keystrokes are done?

Alternatively you could try playing around with DigiKeyboard. This is the function contained in the library that prints each character. If you want to make the Digispark look a little less fishy you can make it a little shield with a 3D printer, many people published their own projects but these two are the best ones in my opinion:.

And finally no, you cannot install a file system on the controller. Init Discord Partners. I have my Digispark, how open hardware badusb query I use it?

This is a direct link to the latest version of the drivers, unzip the folder inside the archive and open one of these two executables to install the 32 or 64 bits version of the drivers: Open hardware badusb query for the final step, open the Windows Device Manager. WebClient" ; DigiKeyboard. Can I use Rubber Ducky scripts on my Digispark? Conclusions And this is all I had to say for today, aside from the fact that if you wish to write scripts for other open hardware badusb query layouts you will have to edit the hardcoded numbers contained in DigiKeyboard.

If open hardware badusb query want to make the Digispark look a little less fishy you can make it a little shield with a 3D printer, many people published their own projects but these two are the best ones in my opinion: And finally no, you cannot install a file system on the controller.
