VHL IoT Penetration Testing Course

The Internet of Things (IoT) has become a core part of modern infrastructure. Consumer devices, industrial control systems, medical equipment, and vehicles increasingly rely on embedded systems connected to local networks and the internet. Advances in areas such as low-power wireless protocols, distributed architectures, and edge computing have accelerated adoption and expanded the attack surface of these systems.

From a security perspective, IoT remains one of the weakest domains in modern computing. Devices are frequently deployed with minimal hardening, outdated components, and little consideration for long-term maintenance. As a result, exploitable weaknesses commonly exist across the entire stack: hardware interfaces, bootloaders, firmware, network services, web interfaces, companion mobile applications, cloud backends, and proprietary communication protocols. In many cases, these weaknesses can be chained to achieve full device compromise or pivot deeper into connected internal networks.

The VHL IoT Penetration Testing course is designed to address these realities. You will work hands-on with real-world IoT targets such as routers, IP cameras, and embedded devices, and learn how to systematically analyze them for vulnerabilities, misconfigurations, and design flaws. The focus is on practical techniques and attacker methodology, not theory. This course is intended for those who want to understand how IoT systems fail in practice and how to assess their security in a realistic, adversarial context.

The IoT Penetration Testing course starts with foundational IoT concepts and progressively moves toward more advanced security testing concepts and techniques. Below is an overview of the technical skills and testing methods you will learn and apply.

The skills and techniques outlined above are introduced and developed throughout the course modules. The syllabus below shows how these topics are structured and how they build on each other across the course.

Course Syllabus

The course curriculum is divided into comprehensive modules, each covering specific theoretical concepts and practical skills. Below is an overview of all course modules and their individual lessons.

The course begins with a theoretical introduction to IoT devices, their risks, and vulnerabilities. We then explore safety-related topics, followed by a brief overview of IoT security laws, standards, and guidelines. For the security testing of physical IoT devices you need various tools and measuring instruments. In module 5 of the course we will cover all the tools you may ever need in your IoT and Hardware Hacking Lab, such as a multimeter, logic analyzer, oscilloscope, various chip programming tools (CH341 and T48), probes, Software Defined Radios (SDR) and various development boards. In the three subsequent modules, we focus on mapping and enumerating the attack surface of the IoT device under test, emphasizing specifications, product information, network, configuration, vulnerabilities and hardware.

In the modules that flow we will delve deeper into the various serial communication protocols used in IoT devices, for example UART, I2C, SPI and JTAG. You will learn how to interface and communicate with various hardware debug interfaces and serial communication protocols. Knowledge of these communication protocols and hardware debug interfaces can give penetration testers access to the internal components of the IoT device, such as the firmware and sensitive information on the device.

Obtaining the firmware of an IoT device can be done in various ways, such as by reading the flash memory chip with a programmer tool, shell access to the bootloader or a system shell via UART. Network connections and over-the-air (OTA) firmware update mechanisms also provide opportunities to obtain the firmware of IoT devices by intercepting the network communications with firmware update servers. When nothing else is working to get the device firmware we will demonstrate how to obtain the firmware by desoldering the flash memory chip of the device and reading it with a chip programmer.

With access to the firmware, you can apply various static and dynamic firmware analysis techniques, for example by analyzing the file system for sensitive information, such as passwords and hardcoded encryption keys. You will also learn how to reverse engineer device functionalities and binaries with Ghidra to understand how the device operates and to identify vulnerabilities.

In the last modules of the course, we focus on emulating firmware and architectures with QEMU and debugging IoT systems with GDB. We will address the most commonly found vulnerabilities in IoT devices: Buffer Overflows and Remote Command Execution vulnerabilities. In these modules you will learn how to identify and exploit these type of vulnerabilities in IoT devices. The final module of the IoT hacking course focuses on the responsible disclosure of discovered vulnerabilities.

Participants are expected to have a basic understanding of virtual operating systems, Kali Linux, TCP/IP networking and be able to work with a command line. Limited knowledge of penetration testing and programming languages is also an advantage but is not required to start the course. If you do not have basic knowledge of penetration testing and programming languages, additional research during the course may be necessary to fully understand all concepts and modules.

To successfully follow and complete the IoT Penetration Testing Essentials course, it is not necessary to purchase any tools, components or devices; this is completely optional. The course explains in detail how the target IoT devices are put together and how various hardware hacking tools are applied to these test devices. The output of these tools, usually a measurement, data capture, firmware or other file, will be shared with you during the course for performing the practical assignments and your own research. This way, you don’t need to invest in test tools and targets to complete the course.

If you also want to gain experience with hacking actual hardware devices you will need some tools, components and target devices. The target IoT devices can be the same devices covered in the course but exploring other devices is of course also an option to maximize the learning experience. Keep in mind that the investment in your own hardware hacking lab can add up considerably in cost. Decide in advance what you need and how you want to deploy it for testing IoT devices.

Our advice is to first complete the theoretical part of the course and the software-related practical assignments. Then decide what you want to do with the practical side of hardware hacking and what tools and components you need for that. The minimum required hardware hacking tools are a multimeter, logic analyzer, CH340 USB to serial adapter, CH341 programmer, opening and hand tools, wires and clips, and IoT targets for testing. Some of these tools, such as the CH340 and CH341 tools, can also be configured on a Raspberry Pi device.

The IoT Penetration Testing Essentials course leads to the VHL Certified IoT Penetration Tester – Essentials level (CIPT-01) certification. The exam is designed to evaluate essential skills required to identify and analyze vulnerabilities in IoT devices through a standalone case scenario.

Students must perform a practical assessment on a simulated IoT device and produce a professional penetration testing report. The focus of the exam is on critical thinking and problem-solving skills rather than simply repeating techniques from the courseware.
