Bash Bunny payloads can execute keystroke injection attacks similar to the USB Rubber Ducky by using the HID ATTACKMODE. By default this mode uses a US keyboard layout. Additional keyboard layouts may be developed by the community. Installing additional keyboard layouts is similar to use of the tools folder on the root of the USB mass storage partition. On boot-up into arming mode, any two-letter-country-code.json file located in the /languages folder on the root of the USB mass storage partition will be installed. The file will remain in /languages after installation.

With a new language file installed, one may specify the keyboard layout from a payload by using the DUCKY_LANG extension. This extension accepts a two letter country code.

Example:

  DUCKY_LANG us
