Bash Bunny Firmware Upgrades

Bash Bunny firmware can be downloaded from the Hak5 Download Center.

Installation Overview

Your Bash Bunny can be easily upgraded to the latest firmware version. Just copying an upgrade file to the root of the Bash Bunny flash drive in arming mode, safely eject it, and plug it back into your computer in arming mode.

The first time the Bash Bunny is upgraded it will indicate the flashing process with a red blinking LED for up to 10 minutes. The flashing process will be followed by a green LED to indicate that the Bash Bunny is rebooting. Finally the standard slow blinking blue LED will indicate that the flashing process has succeeded and arming mode is ready.

WARNING: Do not unplug the Bash Bunny while firmware upgrade is in progress. Doing so will spell certain doom. WARNING: Do not extract the contents of the downloaded .tar.gz to the Bash Bunny or change the name of the downloaded .tar.gz file. Doing so will put your Bash Bunny into a boot loop on firmwares 1.0 to 1.3.

NOTE: Following version 1.0, all future upgrades and firmware recoveries will be indicated by a special LED “police” pattern, alternating quickly between red and blue.
