Smart Home Technology and the Risks Associated with It
Welcome to this post on smart home technology and personal privacy. Last year, security researchers identified more than 100 vulnerabilities in home automation systems. Some of these flaws were found in consumer devices like mobile apps and web interfaces that allowed a malicious person to take over the system and gain access to the owner’s mobile phone, personal data, and home infrastructure. This is not the first time the security of consumer electronics has come under scrutiny. A number of manufacturers have been forced to recall products because of a serious bug found in its chipsets. Many others have recalled smart devices because of flaws found in their wireless security protocols.
Smart homes are of particular concern because they represent the increasingly pervasive use of technological devices by individuals in their own homes. Such devices can easily be used by a stranger with physical access to a user’s home to compromise the security of that person’s personal belongings and networks. The increasing ubiquity of these gadgets and their vulnerability to attacks may seem to suggest that these gadgets are on their way to replacing key household appliances. However, we need to remember that smart home devices do not substitute for the role of traditional devices, such as door locks, alarm systems, thermostats, and lights. They complement these products by providing an additional layer of security to homes that people rely on more and more.
The device itself is secure because it is designed with the customer in mind, and no matter what it is doing, it is attempting to protect the user’s personal information. The lack of transparency and independent verification regarding smart home device security, especially concerning their “smart” functions, has only served to heighten people’s concerns. As devices that monitor and control home heating and cooling, the internet of things (IOT), and other home security and automation systems are integrated into homes, users need to know the level of security of these devices. In this post, we will first go over some basic aspects of the smart home, and then explain how a malicious user might take advantage of them to hack into a home network. We will also look at the basic security measures that users can take to prevent cybercrime.
What Is the Smart Home Technology?
A smart home is a household that employs the internet, voice assistants, and wireless technologies in order to automate household functions. The internet of things (IoT), as the smart home describes the expanding use of sensors and devices to connect home and business-related infrastructures, has already begun to transform homes, offices, and public spaces. Amazon’s Echo, the voice-activated device powered by the popular voice assistant Amazon Alexa, is a major part of the smart home. With access to the user’s cloud-based profile and connected to a home network, it can be used to play music and search for information on a variety of smart home devices.
By buying a smart lock for his front door, a thief can gain access to a house that he is not authorized to be in, or even use it to rob the home when the owner is away. Homeowners can also use a “smart” garage door opener to open and close their garage remotely. Similarly, as companies such as Alphabet and Samsung create smart home offerings, the scope of these systems becomes progressively more complex. At present, consumers need to pay close attention to the capabilities of their devices, and invest the time required to make sure that they are safe.
How Does a Smart Home Attack?
These days, smart home devices can perform a variety of functions that offer a variety of advantages. For example, the Samsung Galaxy S7 smartphone, which allows users to customize their device’s appearance by rotating its casing, allows users to change their device’s wallpaper to one of a wide range of photos, in addition to changing their device’s functionality. A malicious user might exploit this feature in order to disguise their device as another device that the user is authorized to use. A hacker could embed a camera or microphone to monitor the user’s home, or install a product such as a webcam that is disguised to be similar to an adjacent or previously installed webcam, to obtain a user’s private information.
However, more sophisticated attacks that are more easily detectable come into play once a user has become comfortable with a particular system. Once a system is “weaponized”, as the industry calls this, the attacker gains complete access to the home network. An attacker can then extract valuable data such as private information about the user’s social networking accounts, financial details, and anything else of value. In the event that a user’s privacy is breached, a hacker could sell this information on the dark web, or use it in an attack against a company, such as a bank. Attackers could also use the information to steal a user’s identity, and use it to fraudulently acquire goods or services, such as a personal loan.
What You Can Do to Safeguard Against Threats?
Having a variety of security measures and defenses in place is the most effective way of preventing attacks against a home network. An organization can protect itself by regularly monitoring its data for anomalies or threats, such as identifying any unauthorized access to the company’s network.
Employing a firewall helps to block known threats and keep out unauthorized users. In addition, an organization can use antivirus software, firewalls, and other protective measures to provide more robust security. These can include third-party security tools such as anti-virus scanners, firewall, and intrusion detection systems. These protective systems can go a long way in protecting a network from security threats.
Finally, regular password changes will also help to ensure the security of a user’s home network. Smart devices that do not support password protection, such as smart locks, are especially vulnerable to attackers. Regular password changes will also help to ensure that the password of any services that are commonly used on a user’s device, such as a Wi-Fi network password, are more secure than those of a user’s computer, smartphone, or tablet.
Technical Details
The attack model that the cybersecurity researchers describe works by using a benign device, such as a Samsung Galaxy S7 smartphone, to build a bridge into a user’s home network. The hacker then deploys other attack devices such as a script that is designed to gain root privileges over the device. This malware can then install a variety of other attacks, such as the ability to spy on the user’s browsing activities, and infect a home network device with malicious code, including a webcam.
The type of hardware used by the malware’s systems can vary, from low-end components that cost around $200 to high-end components that cost hundreds of thousands of dollars. The attacks can also vary, ranging from using a variety of viruses to a web application that infects the device through several of its webcams. The problem is that it is extremely difficult to trace an attack back to its source because the malware can perform so many actions without requiring additional processing time. As a result, it is very easy for malware to keep doing damage to a network even after it has been removed.
The researchers were able to observe the attack in real time by recording the activity of several of the devices on the user’s home network, including the Samsung Galaxy S7 smartphone. The researchers then streamed the stream to a laptop, which recorded the traffic and transmitted it to a server. After analyzing this traffic, the researchers discovered that all of the devices were communicating with the same server, which hosted the command-and-control server that controlled all of the other malware.
Encrypted Communication Between Devices:
The researchers analyzed the encrypted communication between the devices on the user’s network and the hacker’s server, and found that the communication was encrypted in such a way that the device’s encryption key could only be decrypted by the hacker’s server, which would gain access to the device’s code and its current network credentials. Additionally, the research team was able to determine that the code that executed on the devices was modified and reprogrammed once the device was inserted into the hacker’s network, making it easy for the attacker to infect the devices even if the user has not connected them to the internet in a very long time.
The malware can also be reprogrammed to continue infecting the user’s devices even after the device is removed from the network, which means that a malicious hacker could use malware to infect the user’s device when they go on a trip to another country, steal information while they’re away, or access the user’s personal photos or other sensitive files if their device is connected to the user’s home network. Attackers have also figured out how to set the malware up to continue to spy on the user even when the device is not connected to the internet. A hacker could infect a user’s smartphone, for example, so that their phone sends data when it is connected to a Wi-Fi network, and data when it is not connected to a Wi-Fi network, allowing the hacker to continuously monitor the user’s browsing activity while not being connected to the internet.
We Know There Is More Than One Attack
While it is possible for a hacker to infect devices on the user’s home network, the Samsung S7, or any other device on the user’s home network, without a physical connection to the internet, the researchers found that more than two-thirds of the devices found during their research were actually connected to the internet. The findings indicate that even when a device is on the user’s home network, it is possible for the device to be compromised. As the number of internet-enabled devices increases, the security vulnerabilities of connected devices will only increase as well.
Smart home devices that are designed to connect directly to the internet can have problems connecting to the internet if they have not been updated in a long time, or if they are compromised in some way. With a significant number of these devices being connected to the internet, users have little recourse to protect themselves, even when they use encryption technologies, and even if their devices are infected. As the Samsung S7 demonstrates, if a hacker gains control of the home network, the device is essentially useless.
This is why it’s extremely important for users to regularly update software on their devices. Not doing so makes the device vulnerable to many kinds of attack. A hacker could use malware to infect the user’s device, giving the hacker full control over the device. Once the hacker has full control over the device, they could modify the malware to target a specific individual or enterprise and exfiltrate information from the device, making it difficult for the victim to even know what happened to their device.
The Final Frame
It’s encouraging that research has been done on devices found on our home networks, but it’s still important for us to be aware of this new reality. The Samsung S7 demonstrates that devices found on a home network can be exposed and compromised, and it’s vital that consumers be aware that they have little to no recourse against devices found on their home networks. If a user suspects their device has been compromised, it’s extremely important that they take the appropriate steps to verify that the device was not compromised by malware.
All internet enabled devices that are used on a home network should have the latest security patches installed, even if the user does not update them regularly. Users should also have access to information about when their device was last updated. For devices that do not have a web browser, users should contact their device’s manufacturer to get more information about when the device was last updated. Most importantly, users should be mindful of any devices that may be connected to a home network, and ensure that these devices are updated with the latest patches and have the latest security updates installed.
If a device is compromised and the hacker gains control of the home network, all the user can do is hope that the device will be upgraded with the latest security patches. If a device is not updated or not patched, then all the user can do is hope that the device can get updated when the device is brought into the same physical vicinity of an internet connection, or if the user purchases an update from the manufacturer.
