USB Rubber Ducky


The USB Rubber Ducky is a Human Interface Device programmable with a simple scripting language allowing penetration testers to quickly and easily craft and deploy security auditing payloads that mimic human keyboard input. The source is written in C and requires the AVR Studio 5 IDE from atmel.com/avrstudio. Hardware is commercially available. Imagine plugging in a seemingly innocent USB drive into a computer and installing backdoors, exfiltrating documents, or capturing credentials. With a few well crafted keystrokes anything is possible. If only you had a few minutes, photographic memory and perfect typing accuracy. The USB Rubber Ducky injects keystrokes at superhuman speeds, violating the inherent trust computers have in humans by posing as a keyboard. Inventing keystroke injection in 2010, the USB Rubber Ducky became the must-have pentest tool. With a covert design and simple "Ducky Script" language, this bad USB infiltrates systems and imaginations the world over.


  • The USB Rubber Ducky delivers powerful payloads in seconds by taking advantage of the target computers inherent trust all while deceiving humans by posing as an ordinary USB drive
  • Ducky Script is an incredibly simple language
  • Write payloads in any text editor, from notepad to nano
  • REM to comment, STRING for long blocks of text
  • DELAY to momentarily pause and any combination of special keystrokes
  • The USB Rubber Ducky injects keystrokes at superhuman speeds
