Welcome back, cyberwarriors!

A while back, we walked you through building your own hacking drone. It was a drone loaded up with tools designed to help you out during an actual pentest. That was a hands-on project in every sense of the word. If you built one, you probably learned a ton just from putting the hardware together.

This time, we’re doing something different. No soldering iron. We’re staying entirely inside your laptop working with the Damn Vulnerable Drone, which is an open-source simulator built for teaching you exactly how drones get hacked, without you ever touching a real drone.

The Damn Vulnerable Drone

The Damn Vulnerable Drone, or DVD, is a training simulator that was made for people who want to learn drone hacking without buying a drone. It recreates an entire drone system in software, including a flight controller, an onboard companion computer, a ground control station and the wireless links connecting them all. Every piece is there, and every piece runs inside Docker containers on a single computer.

The project was built by Nicholas Aleks, a security researcher and co-founder of DEF CON Toronto, and it’s aimed squarely at intermediate-level red teamers and hacking enthusiasts who want to practice with actual drone protocols and architecture. Drone hardware and radios are genuinely expensive, and a mistake on a real flight controller can be costly. You get to make your mistakes safely, over and over, until you actually understand what you’re doing. DVD runs actual ArduPilot firmware as an ordinary program and pairs ArduPilot’s SITL with Gazebo, which is a 3D robotics simulator that supplies realistic physics. Motors spin up, GPS signals drift the way they really do, and the drone actually flies through a rendered 3D world.

Under the Hood

Every Docker container gets its own address on an internal network. That’s a design choice that mirrors how a real drone’s components actually work. The first piece is the Flight Controller, which runs the ArduPilot firmware itself and talks directly to the Gazebo simulator to process virtual sensor data. The second piece is the Companion Computer, which handles Wi-Fi, camera streaming, telemetry logging, and autonomous navigation, and which also exposes its own web interface for you to interact with. The third piece is the Ground Control Station, the pilot’s side of the operation, covering mission planning, mapping, video, and joystick control, all communicating over a simulated wireless MAVLink link. And the fourth piece is the Simulator itself, the Gazebo container that models flight physics behind the scenes. The documentation specifically tells you not to attack this fourth container directly, because doing so can crash the entire lab out from under you. Everything else is fair game. That one, leave alone.

Getting Started

To install it we need to pull down containers. The project offers two configurations based on whether you have a dedicated graphics card.

If the answer is no, you need Lite Mode. It uses a simplified 2D flight model, needs no GPU at all, and runs comfortably on 4 to 8 GB of RAM, 2 CPU cores, and about 100 GB of disk space. It works on Kali Linux or most other Linux distributions, and you can run it either on bare metal or inside a virtual machine. If the answer is yes, Full Mode gives you the complete Gazebo 3D environment, but it asks more of your machine in return. You need 8 to 16 GB of RAM, 2 to 4 CPU cores, 100 GB of disk space, and a GPU with at least 2 GB of VRAM supporting OpenGL 3.0 or newer. Full Mode is Kali Linux only, and it strongly prefers bare metal, though a virtual machine with GPU passthrough will also work.

Kali Linux is the officially supported operating system either way, and both modes need Docker and Docker Compose installed as the only real software dependency you have to worry about. Once Docker is installed, the whole lab comes up with a handful of commands. 

First, if Docker isn’t already on your system, you’ll want to install it:

kali > printf '%s\n' "deb https://download.docker.com/linux/debian bullseye stable" | sudo tee /etc/apt/sources.list.d/docker-ce.list

kali > curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker-ce-archive-keyring.gpg

kali > sudo apt update -y
kali > sudo apt install docker-ce docker-ce-cli containerd.io -y
kali > sudo systemctl enable docker --now
kali > sudo usermod -aG docker $USER && newgrp docker

Then, clone the repository and pull down the containers. If you’re going with Lite Mode, do this:

kali > git clone https://github.com/nicholasaleks/Damn-Vulnerable-Drone.git && cd Damn-Vulnerable-Drone
kali > docker compose -f docker-compose-lite.yaml pull

From there, three small scripts manage the whole lab’s lifecycle for you:

kali > sudo ./start.sh --mode lite --Wi-Fi wpa2
kali > sudo ./status.sh
kali > sudo ./stop.sh

The start.sh script alone has quite a few options worth knowing about. The –mode full or –mode lite flag picks your simulation type, matching the two modes described above. And the –Wi-Fi wep or –Wi-Fi wpa2 flag is optional, but it’s worth turning on, because it spins up a virtual wireless network alongside everything else. That means your practice can actually include real Wi-Fi attacks as the very first step, instead of starting the exercise with network access already handed to you.

Interface and Feedback

Once everything is up and running, DVD is controlled through a browser-based management console sitting at localhost:8000

This console is really where the whole exercise plays out. A set of buttons trigger five distinct flight states: Initial Boot, Arm & Takeoff, Autopilot Flight, Emergency/Return-to-Land, and Post-Flight Data Processing. Each one simulates a different phase of a drone’s mission and opens up a different attack surface for you to explore. Triggering “Arm & Takeoff,” for instance, actually gets the simulated drone airborne, which gives GPS and navigation-based attacks something real to act on.

That mapping to real flight phases is there for a reason. A drone accepts different commands, and trusts different sources of data, depending on whether it’s sitting idle on the ground, climbing out after takeoff, cruising on autopilot, or executing an emergency fail-safe. That means exercises built around each individual state end up testing different parts of the system. 

The Attack Scenario Library

This is really the heart of the whole project. It has more than 40 named attack scenarios, organized into six categories, each one with its own documentation page and a spoiler-tagged walkthrough waiting behind it. It’s a deliberately broad menu, and it’s worth noticing that some scenarios are about gathering information without being noticed, while others are about actively manipulating or outright breaking the system in front of you.

Reconnaissance scenarios are about passively fingerprinting the drone, its companion computer, and its ground station by watching Wi-Fi and MAVLink traffic go by, without touching anything yet. Protocol Tampering scenarios involve spoofing telemetry values the drone reports, things like its GPS position, battery level, or system status, to see whether the system properly checks what it’s being told. Denial of Service scenarios focus on disrupting flight through methods like Wi-Fi deauthentication or flooding the communication link until it can’t keep up. Injection scenarios involve sending forged commands directly into the MAVLink stream, ranging all the way from a simple waypoint change to a full companion-computer takeover. Exfiltration scenarios are about pulling data off the drone entirely, whether that’s flight logs, mission plans, or content from the camera feed. And Firmware Attacks focus on modifying or reverse-engineering the ArduPilot firmware itself, right down at the code level.

Because every scenario runs against fully simulated components, you actually get to see the complete effect of an attack play out. A spoofed GPS reading really does nudge the simulated flight path off course. A flooded communication link really does degrade control, right in front of you. And you get to watch all of it happen without any of the legal or physical risk that would come with testing the same techniques on live hardware.

Wi-Fi and Non-Wi-Fi Modes

DVD can be deployed in two different ways, and which one you pick depends on which part of the attack chain you actually want to practice. Wi-Fi Mode spins up a real, functioning virtual wireless network, broadcasting an SSID called Drone_Wi-Fi on the 192.168.13.0/24 range, with your choice of weak WEP encryption or the considerably stronger WPA2. This lets the whole exercise start from the very beginning, with you playing the role of an attacker who doesn’t have network access yet and has to earn it.

Non-Wi-Fi Mode skips that entire step and simply brings the containers up directly. This is useful if you just want to focus purely on protocol-level attacks, or if you’re not running inside a Kali VM with wireless card support to begin with. In this mode, the documentation asks you to treat the situation as though initial access to the drone’s data link has already been established, so you can jump straight to the MAVLink-level work.

Summary

The Damn Vulnerable Drone takes an idea that’s already well proven in web security and applies it to a domain where practicing on the real thing tends to be expensive. By simulating a full ArduPilot and MAVLink drone stack inside Docker, right down to Wi-Fi, camera streaming, and flight physics, it hands penetration testers, students, and researchers a realistic, disposable target, backed by more than 40 documented attack scenarios and built-in walkthroughs to guide the way. It won’t teach you to fly a real drone. But it will teach you exactly how one can be hacked, and for anyone working in drone security, that’s the more useful skill anyway.

Welcome back, aspiring cyberwarriors!

Think back to the first time you installed Kali Linux. It was probably one of those moments where you realized just how many cybersecurity tools existed. Your applications menu was packed with hundreds of tools covering everything from recon and vulnerability scanning to exploitation, password attacks, wireless security and much more.

At first, it was exciting. But most beginners spend hours clicking through the menus wondering what every tool does and when they should actually use it. Unfortunately, the sheer number of applications quickly becomes overwhelming. Even if you dedicate time to learning them, chances are you’ll forget many of their names simply because there are so many available. On top of that, documentation isn’t always beginner-friendly. Some projects have excellent documentation, while others assume you already know exactly what the tool is supposed to do before you even start reading.

The good news is that you don’t have to memorize hundreds of commands or remember every tool available. Instead, you can build your own arsenal of references that helps you quickly find the right tool.

In this article, we’re going to build exactly that. We’ll explore two resources called Arsenal-NG and Arsenal, both of which are designed to make finding offensive security tools, payloads, commands much faster.

Arsenal-NG

The first tool we’ll look at is Arsenal-NG. The name pretty much explains what it does. Arsenal-NG is essentially a searchable collection of offensive security tools, commands, and predefined workflows. Whether you’re doing reconnaissance, exploiting a service, generating payloads, Arsenal-NG can help you find the right tool for the job.

Let’s install it.

kali > git clone https://github.com/halilkirazkaya/arsenal-ng.git
kali > cd arsenal-ng
kali > make build

Once compilation finishes, you can launch the program directly. For convenience, you may also want to move the binary into one of the directories listed in your PATH environment variable. Doing so allows you to start Arsenal-NG from any directory. 

kali > arsenal-ng

When it starts, you’ll immediately notice a large collection of tools organized inside the interface. Each tool includes predefined presets for different kinds of operations. 

To display the complete list of available tools, simply run tools

If you already know what kind of task you’re trying to accomplish but don’t remember what tool can do it, you can use the built-in search feature. Searching by keywords makes it easy to discover them.

Once you’ve found the tool you need, selecting one of its presets walks you through the required parameters. There you simply provide the requested information and let it generate the command for you.

If you need additional information about the application itself, run help.

Arsenal

Unlike Arsenal-NG, Arsenal focuses primarily on web exploitation and can be used directly from your browser. There is no installation process, making it convenient when you simply need a quick reference.

You can access it here.

One thing worth mentioning is that the website supports multiple languages. If the interface isn’t already in English, simply switch the language using the selector in the upper-right corner. Once inside, you’ll notice that the content is organized into several different sections, each designed to help with a different phase of a web penetration test.

One of them is Payloads.

This area contains a huge collection of payloads covering many different types of web vulnerabilities and exploitation techniques. Whether you’re working with command injection, SQL injection, XSS, SSTI, XXE, deserialization, or other common web vulnerabilities, chances are you’ll find useful examples here.

Another valuable section is Attack Chains.

Rather than simply providing payloads, Attack Chains guide you through the overall exploitation process. They outline the sequence of steps typically required to compromise a target.

The Commands section is another good reference.

You can build the command you need by selecting the appropriate options.

Then we have Wordlists.

There are numerous wordlists organized into logical categories, making it much easier to find exactly what you’re looking for. Each category often contains several different wordlists optimized for different situations. 

You’ll also find a large collection of Scripts.

These scripts cover a wide variety of purposes, including reconnaissance, AI-related security checks, subdomain takeovers, automation and more.

Of course, we’ve only scratched the surface. Arsenal contains more additional sections that are worth exploring on your own. Spend some time clicking through the different categories and seeing what they have.

Summary

Building your own cybersecurity arsenal isn’t about memorizing every command ever written. In fact, no experienced pentester or hacker remembers every tool, every option or every payload. There are simply too many of them, and new ones are being developed all the time. Arsenal-NG and Arsenal can help you organize knowledge. They are valuable when you’re getting started and they remain just as useful years later when you’re experienced.

Since many of these tools fall into different categories, such as network pentesting, web pentesting, bug bounty hunting, and more, the best way to develop your skills is through our Member Gold subscription. It gives you access to a wide variety of training courses covering different areas.

Welcome back, aspiring cyberwarriors!

During pentests, it’s not uncommon to find a Grafana somewhere inside an organization’s infrastructure. Sometimes it can even be exposed directly to the Internet. It’s always worth checking Grafana for vulnerabilities, as it has been affected by multiple security issues over the years.

What is Grafana

Grafana is an open-source monitoring and visualization platform used by organizations to display dashboards containing information collected from servers, applications, databases, cloud services and networking equipment. Administrators rely on it to monitor the health of their infrastructure in real time, making it one of the most widely deployed monitoring apps in enterprise environments. Since Grafana often connects to numerous backend services and contains valuable configuration information, compromising it can sometimes give hackers an excellent foothold into the rest of the network.

Of course, you could manually inspect every Grafana installation looking for known vulnerabilities, but that quickly becomes time-consuming, especially during larger engagements where multiple servers have to be assessed.

Fortunately, there is a Grafana-Final-Scanner. It’s a tool designed specifically to automate this process. Instead of manually checking every instance the scanner performs the work for you by checking whether the target is vulnerable to a collection of publicly known vulnerabilities.

Grafana-Final-Scanner

We’ll begin by downloading the repository and installing its dependencies.

kali > git clone https://github.com/Zierax/Grafana-Final-Scanner.git
kali > cd Grafana-Final-Scanner
kali > python3 -m venv venv
kali > source venv/bin/activate
kali > pip3 install -r requirements.txt

Once everything has been installed successfully, it’s worth taking a quick look at the list of vulnerabilities supported by the scanner.

At the time of writing, the tool is capable of checking for more than fifteen different Grafana vulnerabilities.

Now let’s point it at our target.

kali > python3 scanner.py -u https://target/grafana/login

After a short scan, the tool analyzes the target and reports any vulnerabilities it successfully identifies.

In our case, the results were promising. The scanner identified CVE-2024-8118 and an OAuth Authentication Bypass vulnerability. It also gave us the URL. We opened the page and the application asked us for an administrator key that we obviously didn’t have.

Fortunately, web applications don’t always behave exactly as their developers intended. Developers occasionally leave sensitive information inside the application’s front-end code. JavaScript, HTML comments, hardcoded credentials, authorization logic have all been discovered by hackers countless times over the years.

With that in mind, we opened the page’s HTML source code to see exactly how the authorization process was implemented. The comments were written in Russian, but the logic itself was fairly easy to understand.

Instead of verifying a specific administrator key, the application simply checked whether any key existed. So the validation routine wasn’t actually validating the value at all. It simply checked if some key was provided.

The next step was straightforward. We opened the browser’s Developer Console and manually created the expected key.

The application accepted it. 

We bypassed the authentication and accessed the admin panel. 

Finding a vulnerability is only part of the pentest. Understanding how the application behaves after exploitation is equally important. Sometimes the scanners get you only halfway there, while manual analysis can help you find the remaining pieces needed to fully demonstrate the impact.

It’s also a good reminder that developers occasionally leave sensitive information hidden inside client-side code. You never know what useful information may have been left behind.

Web Interface

While running the scanner from the command line works perfectly for testing targets, the project also includes a convenient web interface.

This can be useful during larger pentests where dozens of Grafana instances need to be assessed.

You can start it with this command:

kali > python scanner.py --serve --db vulndb.json

Summary

Grafana is one of the most common monitoring platforms you’ll encounter during internal and external penetration tests. Because it frequently contains sensitive operational data and often communicates with numerous backend systems, compromising it can sometimes provide hackers with an excellent entry point into an organization’s network.

Grafana-Final-Scanner can make it much easier to determine whether your Grafana is exposed to known vulnerabilities.

If you enjoy web application pentesting and would like to improve your skills for bug bounty hunting, we have our Web Application Hacking training. You’ll gain the practical knowledge and skills you need to start finding web application vulnerabilities.
