About the Key Croc

The Key Croc by Hak5 is a keylogger armed with pentest tools, remote access and payloads that trigger multi-vector attacks when chosen keywords are typed. It's the ultimate key-logging pentest implant.

Hak5 Key Croc Hardware Features

More than just recording and streaming keystrokes online, it exploits the target with payloads that trigger when keywords of interest are typed.

By emulating trusted devices like serial, storage, HID and Ethernet, it opens multiple attack vectors – from keystroke injection to network hijacking.

Imagine capturing credentials and systematically using them to exfiltrate data. Or pentest from anywhere, live in a web browser with Hak5 Cloud C².

It's simple too. A hidden button turns it into a flash drive, where changing settings is just editing a text file. And with a root shell your favorite pentest tools like nmap, responder, impacket and metasploit are at the ready.

About DuckyScript™

With the Key Croc in 2020, DuckyScript 2.0 has been introduced.

While many of the Hak5 Tools run various versions of DuckyScript; like the Bash Bunny and even the officially licenced DuckyScript compatible devices from O.MG - the Key Croc uses an INTERPRETED version of DuckyScript

Interpreted DuckyScript means the payload runs on the device straight from source code (the code you write e.g. QUACK STRING test).

The files in this repository are the source code for your payloads and run directly on the device no compilation required - simply place your payload.txt in the appropriate directory and you're ready to go!

DuckyScript Ecosystem

Languages

Support for different keyboard layouts can be found, modified or contributed to in the languages/ directory of this repository.

Unlike devices such as the Bash Bunny and USB Rubber Ducky - the Key Croc's language files are just a bit different. Due to the nature of supporting real time decoding and real time MATCH payloads the Croc has a bit more on it's plate in regards to what it means to support a keyboard language layout.

For example, while performing Keystroke Injection - you may only ever require the 1 from the number row, or the right GUI key. The Key Croc on the other hand needs to not only know how to interpret the entire keyboard but also a large variety of keyboard combinations to make matching and triggering on payloads work as you would expect it to; accurately and without delay. For these reasons, the Key Croc's language files are monolithic, statically and programatically generated to provide the absolute best possible experience.

The default language is US (languages/us.json)

Hak5 Cloud C²

Cloud C² makes it easy for pen testers and IT security teams to deploy and manage fleets of Hak5 gear from a simple cloud dashboard.

Cloud C² is available as an instant download. A free license for Community Edition is available which is not for commercial use and comes with community support. The Professional and Teams Editions are for commercial use with standard support.

Hak5 Cloud C² Web Interface

Cloud C² is a self-hosted web-based command and control suite for networked Hak5 gear that lets you pentest from anywhere.

Linux, Mac and Windows computers can host the Cloud C² server while Hak5 gear such as the WiFi Pineapple, LAN Turtle and Packet Squirrel can be provisioned as clients.

Once you have the Cloud C² server running on a public-facing machine (such as a VPS) and the Hak5 devices are provisioned and deployed, you can login to the Cloud C² web interface to manage these devices as if you were directly connected.

With multiple Hak5 devices deployed at a client site, aggregated data provides a big picture view of the wired and wireless environments.

Hak5 Cloud C² Web Interface - Teams Edition - Sites

Hak5 Cloud C² Teams edition comes full of features designed to help you manage all of your remote Hak5 devices with ease:

Multi-User
Multi-Site
Role-Based Access Control
Advanced Auditing
Tunneling Services including web Terminal and WiFi Pineapple web interface proxy

Contributing

View Featured Payloads and Leaderboard

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

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

Payloads should be submitted to the most appropriate category directory. These include credentials, exfiltration, phishing, prank, recon, etc.

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.

Each payload should have a unique, descriptive directory and filename, e.g., WIN_powershell_SMB_exfiltration.txt

The directory name for the payload should match the payload file name.

If the payload is OS specific (I.e., a Windows Powershell attack), the filename should be prefixed with that OS. Prefixes include:

WIN_ for Windows
MAC_ for MacOS
LINUX_ for all Linux flavors
MULTI_ for multi-OS payloads

If the payload is OS agnostic (I.e., it substitutes text or otherwise make no interaction with the target OS), the filename should not include an OS prefix.

If multiple individual OS specific payloads are included, the directory name should be prefixed with MULTI_ while each payload file name therein should be prefixed with the specific OS.

Payload Configuration

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

Remember to use PLACEHOLDERS for configurable portions of your payload - do not share your personal URLs, API keys, Passphrases, etc...
Make note of both required and optional configuration(s) in your payload using comments at the top of your payload or "inline" where applicable

Payload Documentation

Payloads should begin with # 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

If a payload requires additional documentation for use, such as requiring special dependency installation or use of the LED, it should be documented in the code block. In the case of LED for status, use the following:

# LED ERROR: Dependency not found
# LED SETUP: Starting services
# LED ATTACK: Performing attack
# LED SPECIAL: Exfiltrating loot
# LED CLEANUP: Removing temp files
# LED FINISH: Attack complete

If custom color/patterns are used instead of standard LED states, designate these status indications accordingly.

Payloads may optionally include a readme.md file for documentation.
