Bad USB v1.1

---

Ducky Script intrepter/executer for Arduino boards.

Designed as a non-stealth version of a usb rubber ducky Hak5 for times when stealth doens't matter and you want the ability to run any number of scripts.

The design incorporates an Arduino Pro Micro, Adafruit Micro-SD breakout, OLED Display and Mini Rotating Momentary Button.

Use this for LEGAL - NON NEFARIOUS uses - like automatically setting passwords or other IT tasks.

External Libraries

The script makes use of the following external libraries (All available from the Arduino library manager):

• Keyboard
• SPI
• SD
• Wire
• ACROBOTIC_SSD1306

Note: We need to make a couple of changes to the ACROBOTIC_SSD1306 library. As of publishing time this project uses v1.0.1 which doens't seem to have native 128x32 support.

ACROBOTIC_SSD1306.h Change the SSD1306_Max_Y variable to SSD1306_Max_Y = 31.

ACROBOTIC_SSD1306.cpp Add sendCommand(SSD1306_Max_Y); to line 32 in init() Remove sendCommand(0x3F); from init()

Adjust the inner loop of clearDisplay() from i=16 -> i=26. This will clear the while screen. If not changed it will leave pixels lit even when cleared.
