DuckyScript is the domain-specific language created by Hak5 for programming keystroke injection attacks. It's the engine behind the USB Rubber Ducky, and now runs on nearly every Hak5 implant — O.MG Cable, Key Croc, Packet Squirrel Mark II, WiFi Pineapple Pager, Bash Bunny, and the Shark Jack. Despite its simple appearance, the language has evolved through three major generations with dramatically different capabilities.
