Rubber ducky scripts that were produced during kompetensdag in Gothenburg

Kompetensdag Gothenburg 2022-04-29

In this kompetensdag we will try to create and program our own Rubber Duckys. As these are expensive and hard to come by we will create our own.

What is a Rubber Ducky? It is a programmable USB that emulates a keyboard. The possibilities are endless, but some examples are inactivating antivirus, keylogger or creating a reverse shell.

Every participant will get the necessary hardware and can keep it afterwards. The workshop is limited to 20 people.

Hardware

USB-A port Programmable Digispark board

Software

Install the Arduino IDE

Add the string https://raw.githubusercontent.com/ArminJo/DigistumpArduino/master/package_digistump_index.json to Arduino -> Preferences -> Additional Boards Manager URLs

Now you can download the board configuration Tools -> Boards -> Boards Manager. Select contributed and install DigiStump AVR Boards v1.7.5.

Select the DigiSpark board from Digistump AVR Boards -> Digispark

If you get an error about micronucleus then install it from Github and add it to the specified path in the error message.
