# Bash Bunny Basics

The Bash Bunny by Hak5 is the world’s most advanced USB attack platform. It delivers penetration testing attacks and IT automation tasks in seconds by emulating combinations of trusted USB devices – like gigabit Ethernet, serial, flash storage and keyboards. With it, computers are tricked into divulging data, exfiltrating documents, installing backdoors and many more exploits.

## Where to get payloads

Many payloads are hosted from the centralized library on the Hak5 git repository at [github.com/hak5/bashbunny-payloads](https://github.com/hak5/bashbunny-payloads). Payloads from this repository are contributed from the Bash Bunny community. As with any script downloaded from the Internet, you are advised to proceed with caution. Similarly, many community developed tools exist for working with the Bash Bunny, such as [BunnyToolkit.com](https://bunnytoolkit.com/).

**WARNING:** Community payloads come with absolutely no warranty. You are solely responsible for the outcome of their execution.

## Switch Positions

In Switch Position 3 (closest to the USB plug) the Bash Bunny will boot into _arming mode_, enabling both Serial and Mass Stoage. From this dedicated mode, Bash Bunny payloads may be managed via Mass Storage and the Linux shell can be accessed by the Serial console.

## Mass Storage Directory Structure

![Bash Bunny Directory Diagram](images/bb_diagram2.png)

* The _library_ folder is home to the payloads library which can be downloaded from the [Bash Bunny Payload git repository](https://github.com/hak5/bashbunny-payloads "Bash Bunny Payload git repository")
* The _switch1_ and _switch2_ folders are home to payload.txt and accompanying files which will be executed on boot when the bash bunny switch is in the corresponding position.
* The _loot_ folder is used by many payloads to save logs and other captured information.

## Default Settings

* Username: root
* Password: hak5bunny
* IP Address: 172.16.64.1
* DHCP Range: 172.16.64.10-12

## LED Status

| LED                  | Status                                            |
| -------------------- | ------------------------------------------------- |
| Green (blinking)     | Booting up                                        |
| Blue (blinking)      | Arming Mode                                       |
| Red (blinking)       | Recovery Mode **DO NOT UNPLUG**                   |
| Red/Blue Alternating | Recovery Mode from v1.1 onwards **DO NOT UNPLUG** |

## Tools

While many tools can be installed to the Bash Bunny as you would any typical Debian based Linux computer, such as *apt-get*, *git clone*, a dedicated tools folder from the mass storage partition simplifies the process. Accessible from arming mode, tools in either .deb format or entire directories can be easily copied to /tools on the root of the mass storage partition. Then on the next boot of the Bash Bunny in Arming mode, these tools will be installed - indicated by LED SETUP (Solid Magenta light). 

On boot into arming mode, any .deb file placed in the tools folder will be installed with dpkg. Then any remaining file or directory will be moved to /tools on the root file system.

Some payloads may require additional third party tools. For example, the rdp_checker payload requires impacket to be located in /tools/impacket. This can be installed by copying either the impacket directory or an impacket.deb file to the /tools directory and booting into arming mode. The rdp_checker payload also makes use of the **REQUIRETOOL** Bunny Script extension, which checks for the existence of this tool and exits with a red blinking FAIL LED state if the tool is not found.


## Languages

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 bootup 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
```

# Bash Bunny Serial Console

The Bash Bunny features a dedicated serial console from its _arming mode_. From serial, its Linux shell may be accessed. 

## Serial Settings

* 115200/8N1
* Baud: 115200
* Data Bits: 8
* Parity Bit: No
* Stop Bit: 1

## Connecting to to the Bash Bunny Serial Console from Windows
Find the COM# from Device Manager > Ports (COM & LPT) and look for USB Serial Device (COM#). Example: COM3
Alternatively, run the following powershell command to list ports:
```
[System.IO.Ports.SerialPort]::getportnames()
```

![Putty](images/putty.png)

Open PuTTY and select Serial. Enter COM# for serial line and 115200 for Speed. Click Open.

[Download PuTTY](http://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html "Download PuTTY")


## Connecting to the Linux Bash Bunny Console from Linux/Mac
1. Find the Bash Bunny device from the terminal
```
ls /dev/tty*" or "dmesg | grep tty
```
> Usually on a Linux host, the Bash Bunny will register as either /dev/ttyUSB0 or /dev/ttyACM0.  On an OSX/macOS host, the Bash Bunny will register as /dev/tty.usbmodemch000001.

2. Next, connect to the serial device using screen, minicom or your terminal emulator of choice. 
> If screen is not installed it can usually be found from your distributions package manager.
```
sudo apt-get install screen
```
**Connecting with screen**
```
sudo screen /dev/ttyACM0 115200
```
> Disconnect with keyboard combo: CTRL+a followed by CTRL+\

# Getting the Bash Bunny Online

Getting the Bash Bunny online can be convenient for a number of reasons, such as installing software with apt or git. Similar to the WiFi Pineapple, the host computers Internet connection can be shared with the Bash Bunny. Begin by setting the Bash Bunny to Ethernet mode. For Windows hosts, you'll want to boot the bash bunny with a payload.txt containing ATTACKMODE RNDIS_ETHERNET On a Linux host you'll most likely want ATTACKMODE ECM_ETHERNET. With the Bash Bunny booted and registering on your host computer as an Ethernet device, you can now share its Internet connection.

## Sharing an Internet Connection with the Bash Bunny from Windows
1. Configure a payload.txt for ATTACKMODE RNDIS_ETHERNET
2. Boot Bash Bunny from RNDIS_ETHERNET configured payload on the host Windows PC
3. Open Control Panel > Network Connections (Start > Run > "ncpa.cpl" > Enter)
4. Identify Bash Bunny interface. Device name: "USB Ethernet/RNDIS Gadget"
5. Right-click Internet interface (e.g. Wi-Fi) and click Properties.
6. From the Sharing tab, check "Allow other network users to connect through this computer's Internet connection",  select the Bash Bunny from the Home networking connection list (e.g. Ethernet 2) and click OK.
7. Right-click Bash Bunny interface (e.g. Ethenet 2) and click Properties.
8. Select TCP/IPv4 and click Properties.
9. Set the IP address to 172.16.64.64. Leave Subnet mask as 255.255.255.0 and click OK on both properties windows. Internet Connection Sharing is complete

## Sharing an Internet Connection with the Bash Bunny from Linux

1. Download the Internet Connection Sharing script from bashbunny.com/bb.sh
2. Run the bb.sh connection script with bash as root
3. Follow the [M]anual or [G]uided setup to configure iptables and routing
4. Save settings for future sessions and [C]onnect

~~~~
wget bashbunny.com/bb.sh
sudo bash ./bb.sh

# Technical Details

## Disk Partitions

| PARTITION  | Description                                     |
| ---------- | ----------------------------------------------- |
| /dev/root  | Main Linux file system                          |
| /dev/nandg | Recovery file system (**do not modify**)        |
| /dev/nandf | Mass storage partition (mounted at /root/udisk) |

## Firmware Recovery
If the Bash Bunny fails to boot more than 3 times, it will automatically enter recovery mode. The LED will blink red while the file system is replaced by the backup partition. **DO NOT UNPLUG THE BASH BUNNY DURING RECOVERY**

This process takes about 3 minutes. When complete, the Bash Bunny will reboot as indicated by the blinking green LED.

## Specifications
* Quad-core ARM Cortex A7
* 32 K L1/512 K L2 Cache
* 512 MB DDR3 Memory
* 8 GB SLC NAND Disk

### Power Requirements
* USB 5V ~1.5A
