The process of penetration testing IoT (Internet of Things) devices is unique and easy to overlook. Embedded components, non-standard firmware, and unique radio communications all increase the complexity of IoT security. Despite new security challenges, there has been an incremental rise in the adoption of embedded devices. IoT tech can be found in enterprise environments, homes, and everywhere in between. Between quick growth and a rocky understanding of the underlying technologies, many organizations face new security flaws.
Rhino Security Labs provides advanced IoT pentesting services to identify these risks and prevent your device from being used against you – or your customers.
The Internet of Things refers to the global collective of internet-facing embedded devices. These devices contain various sensors, actuators, and electronic components that interface with web-based applications or cloud technology. They can be security cameras, alarm systems, thermostats, door locks, or even vehicles. With the expansion of IoT, we’re seeing a new wave of great accessibility benefits and impending security concerns.
Rhino Security Labs leads the industry in full-stack IoT penetration testing services, ranging from smart homes and medical systems to smart security systems. Our services go beyond surface level inspection, reverse-engineering the hardware components for dumping firmware and other critical modules. By revealing security vulnerabilities before attackers can take advantage of them, we can eliminate much of the risk that comes with new, misunderstood technology.
We approach this by studying cryptographic protections and communication methods the device uses to connect to the internet, manipulating the cloud services that host your data, and attacking the user interfaces that talk to your device.
Each assessment begins with the devices that make up your IoT ecosystem. We carefully reverse-engineer and disassemble these devices, mapping out components and uncovering vulnerabilities.
With unmatched security hardware expertise and specialized capabilities – such as anti-tamper bypass tools – we provide the deep technical breakdown not found in other services.
The software component of IoT testing is both the device firmware (either provided by the client or extracted in the hardware process) and the associated backend applications or APIs. Reverse-engineering the firmware can reveal sensitive information that can be used in later attacks, such as decrypting traffic using hardcoded encryption keys.
To ensure a holistic and thorough engagement, Rhino Security engineers inspect all possible attack vectors to assess the risk of any given device accurately.
1 – Hardware Disassembly
The process begins with disassembling the device to its barebones, closely examining the pieces down to its circuitry, to understand what it is that makes it tick. This step provides us valuable insight not only into what it can do but how it accomplishes its tasks at a base level.
2 – Firmware Reverse-Engineering
Just as we break down the device itself to understand its inner-workings, we also break down the firmware. To do so, we rely on our engineers’ expert reverse-engineering and binary exploitation.
3 – Signal and Communication Enumeration
Once we have developed a deep understanding of the device’s infrastructure, we move to capturing samples of its radio communication, analyzing cryptographic protocols, and observing how it interacts with its front-end interface (mobile or web application).
Application and API Testing
In this stage, we attempt to compromise the software that the client uses to communicate with the device. Rhino Security engineers implement the same techniques we apply in our standard mobile and web application assessments. Successful exploitation could provide administrator-level access to the device, or perhaps even the host network.
5 – Attack and Exploitation
The culmination of the above steps leads us to the exploitation phase of the test. This phase is where Rhino Security engineers begin to attack the device’s vulnerabilities in real-time using any tools and techniques at our disposal.
6 – Optional: Post Exploitation
If the client feels it would be a good fit for their organization, we can proceed to use the successful exploitation of IoT devices to pivot into their internal network and seek further compromise. Doing so is an extremely effective tactic for simulating a real-world cyber-attack.
