IoT Firmware Analysis — Firmwalker
What I am concerned about is that they are not paying enough attention to what the traditional computing industry has discovered the hard way. Once the easy and obvious security flaws have been corrected, the evil doers will move on to other attack surfaces.
These other vulnerabilities that computer makers have had to deal with will undoubtedly be the next target of IoT hackers. And most important, what to do about them. Many in the IoT ecosystem seem to consider their devices as simple, single use, throwaway devices, such as a basic appliance or embedded system that you ship and forget. This perception is problematic, as more and more IoT devices continue to be developed. Such attack vectors are not a new phenomenon. Network connected computer systems have been dealing with them since the advent of the internet.
The problem has been that the developers of IoT devices have seen their gadgets as simple, single purpose devices that are not susceptible to nefarious acts, and therefore, not easily attackable. Well, it turns out the opposite is true. Since the early days of computing, platform firmware has been created to initialize the system hardware and load the initial software. For traditional computing platforms, this software was typically an operating system loaded from a disk, but even on embedded platforms without a traditional operating system, software is typically loaded from a slow non-volatile storage into faster RAM memory for normal operations.
While simple embedded and SoC systems moved to monolithic solutions like U-Boot and coreboot, most larger and general-purpose systems looked to the UEFI standard.
Ultimately, attackers can then disable protections provided in the software after boot-up and load whatever other programs they so choose. Additionally, they can modify normal software to do their bidding before it has even been started. If the bad guys can get control of the system early enough, that system can be compromised entirely.Deca 300 recipe
The same is true if the code update process is compromised. If a hacker creates their own code and swaps it with the code originally provided by the system manufacturer, then all the bad things listed above can also be accomplished in a system with a compromised system update.
The UEFI specification provides standard interface descriptions and an architecture designed to significantly limit such threats. The two primary technologies used to secure a system from these threats are:. UEFI is the only firmware solution that includes these security features as part of its industry standard. Also, while many security researchers and hackers have been testing its design, no one has been able to find any flaws in the security architecture.
A few implementations have been flawed, but not the design. There are many more security related capabilities provided by UEFI, but they are beyond the scope of this article. I believe there are a couple of major reasons:. How do you get started? Downloading the latest UEFI Specification and trying to read it cover to cover it is probably not the best way to start.
First, UEFI is an interface specification, not an implementation. Only a handful of basic capabilities are required to be compliant with the specification and you can pick and choose from the others based on your needs. There are many educational materials, books, and presentations on the uefi. As an interface specification, it does not drive the actual code implementation of the services described.If you have IoT devices in your home, the truly frightening thing is that your devices might have already been attacked and compromised.
And you might not even know. How many? More than three years ago, experts predicted that by there would be over 20 billion IoT devices in use. But according to this more recent McAfee study that number is projected to be 25 billion by It seems that our predictions of the number of IoT devices are always low, as IoT device adoption is driven by many factors like price and ever-increasing network communication speeds.Karthika pournami 2019 telugu date
And according to Nokia, 5G communication is likely to speed IoT device adoption. So what kinds of vulnerabilities are we talking about? According to the OWASP IoT project all IoT devices have potential security vulnerabilities like weak passwords and other poor default security settings, lack of encryption when devices communicate over the network, and poor or non-existent user-serviceable device management.
At the heart of an IoT device are the key characteristics of the underlying hardware that make IoT devices work:. Essentially, IoT devices contain sensorsactuatorsor both. Sensors acquire data, and actuators control the data or act on the data. All IoT devices have a way to process sensor data, store that data locally if necessaryand provide the computing power that makes the device operate.
If data from multiple sensors needs to be coordinated, or if data needs to be stored in flash memory for whatever reasonit is the data processing component of the IoT device that does it.
The firmware that runs an IoT device is the onboard software that sits between the hardware and the outside world, and generally falls into one of two categories: embedded firmware or operating system-based OS-based firmware. IoT devices are resource-constrained, so they often use custom-built, embedded firmware, which is another term for the software that runs on the device.
In many cases, the only cost-effective solution for device manufacturers is to engage programmers with a deep understanding of the hardware to write embedded software firmware to interact with the hardware. Embedded software engineers have to perform double-duty. An IoT device now probably runs an operating system OS that provides an abstraction layer between the hardware and other software that runs on the device.
A popular OS choice for many device manufacturers is Busyboxa stripped down version of the Unix operating system that contains many of the most common utilities, has a very small footprint, and provides many capabilities of Unix in a single executable.
IoT devices most often communicate wirelessly, which means they can be anywhere in your home or enterprise. The communication needs of the device change depending on how the device is designed to work. Some devices are designed to work by making a direct From there, the device can access the internet.
A motion-activated security camera is a popular example of this type of device, which uses wifi to send its data to a cloud server, for example, which you can access via an app on your smartphone. Some devices are meant to work as part of a group of IoT devices. In the simplest scenario, you press the WPS button on your IoT device, then press the WPS button on the router, and the two devices are eventually connected.
Other devices create a Wifi access point you connect to using an app on your smart phone where you to enter your wifi network credentials, which will be used later by the IoT device to connect to your wifi network.
Still other devices, like hubs and gateways, scan and add devices that it detects are in your home or business. You simply configure the gateway so it has internet access, tell it to sniff out other devices, and follow the device-specific instructions to put the devices in pairing mode so that they can connect to the gateway.
Once your device is connected to the network, you can monitor and control it. One way to control it is through a smartphone, either connected to the gateway directly inside your home, for example or through an interface to a cloud service. You access these devices directly over the internet, bypassing the need for the device to connect to a hub or gateway.
Many IoT devices are installed in homes and businesses, but are exposed directly to the internet by modifying your firewall to enable port-forwarding.Start your free trial. IoT is the next big technology that will change the way we communicate and exchange data. Every day thousands of IoT devices are coming into the market. Most of these devices collect and exchange data over the cloud.
Not much effort has been put into securing the IoT devices, thus understanding the security of IoT devices and their communication is of utmost importance. If one has a close look at any IoT Network, there are many components to be secured. Some of them are listed below —. Security of all the components mentioned above cannot be covered in a single post. In this post, I will explain how to analyze the firmware of any IoT device since not much resource is available on firmware security.
Firmware is a software program programmed on a hardware device. It provides the necessary instructions on how the device communicates with the other computer hardware. Have you seen something like shown in the image below?
Put simply, the software running on any IoT device is termed as Firmware. Firmware Analysis Methodology — To analyze any firmware, there are two ways to do so — one is manual and other uses a tool.Scania model trucks
Manual Analysis consumes a lot of time, and due to time constraints often it is not possible to do a manual analysis. Thus, automated analysis of firmware comes in handy. In this post, we will learn how to use a tool named Firmwalker for analyzing the firmware. Please download it for performing firmware analysis practically. Above are the issues widely found in IoT firmware and the tool does a great job in identifying the issues.
