Can hackers who gain access to an organizations iot cause physical damage?

Generally, computer hacking refers to accessing someone's computer, or a similar device such as a smart phone, without permission. If someone hacks an organization, that individual can steal sensitive data such as documentation of business processes and trade secrets or contact information for employees and customers. Hackers can also damage data by erasing or changing the data, or by damaging the actual hardware. The impact of hacking can also include legal liability, if someone else's data is stolen or a company is unable to fulfill contracts because of hacking issues.

How Computer Hacking Works

Generally, computer hackers gain access to a computer or to a similar device by exploiting a flaw in the computer's software or configuration, or by using stolen usernames and passwords. Once hackers have access, they can impersonate legitimate users for accessing data, as well as change files and configurations, or they can manipulate other devices connected to the compromised computer. Consequences of hacking can be serious, depending on which machines hackers have accessed and what level of access they have achieved.

How to Reduce the Impact of Hacking

Hackers can use exploits, or flaws in computing technology, to gain access that they shouldn't be able to access. To avoid this happening to you, make sure you keep your software up to date, and pay special attention to the various security fixes that software creators roll out. You can also use firewall software, which limits hackers' abilities to access your computer across the internet and antivirus software, which detects and restricts automated malicious software.

Watching for Phishing Attacks

Hackers can also use actual usernames and passwords or other credentials to impersonate the actual users, so that they can access the computers. They can either guess passwords if users choose weak or obvious ones or attempt to steal them from users by fraud. Fraudulent messages tricking people into revealing their usernames and passwords are commonly known as phishing messages, and they can be sent by email, text message or other channels.

Steps for Preventing Phishing Attacks

If you're unsure whether a person, website or app asking for your password is legitimate, play it safe and avoid revealing your login information. Contact the person or organization in question and verify the request is legitimate. If you do think you've given your username and password to a scammer, take action as soon as possible. Change the password and notify the organization that issued the account, whether it's your employer's IT department or a third party.

Hacking and Data Theft 

One of the most common consequences of hacking is data theft. Hackers will gain access to a computer in order to steal sensitive information, including additional usernames and passwords, credit card numbers, sensitive corporate data or other valuable information. They might do this for monetary gain or simply out of curiosity.

Data Theft Has Serious Consequences

Data theft can be serious for an organization or an individual. Losing business information to thieves can mean a loss of competitive advantage for a company. It can also bring legal consequences, if the data is protected information that belongs to a third party, such as a customer. If private communications such as text messages or email messages are stolen, this can also be quite embarrassing for the people involved, if sensitive subjects were discussed.

If the data stolen includes additional usernames and passwords, the stolen data can be used to compromise additional computers. If bank or credit card data is stolen, that can also be used to steal money or make fraudulent purchases. If you think your usernames and passwords have been stolen, then change usernames and passwords immediately. Additionally, contact financial institutions if your account information seems as if it has been compromised.

Hacking and Sabotage

The effects of hacking can also include damage to digital data or even to physical equipment. Some hackers may purposely destroy data in order to harm their targets. In other cases, valuable data may be accidentally damaged or not saved, because of interference from hackers or the software that hackers use. Data may also be encrypted and held for ransom and rendered unusable, if hackers aren't paid. In rare cases, hackers may even use computers that control other devices to damage hardware or physical equipment.

The internet of things (IoT) is a highly developed space that is home to a vast amount of sensitive data, making it a very attractive target for cybercriminals. Threats and risks continue to evolve as hackers come up with new ways to breach unsecured systems -- posing a threat to the ecosystem itself. Let’s take a look at the leading threats and risks to the IoT and the associated vulnerabilities that must be secured.

What is the internet of things (IoT)?

The Internet of Things (IoT) is a network of intertwined devices, software, sensors, and other ‘things’ which enable the world to be connected throughout physical space. This can include business software, smart home devices, care monitoring systems, mobile phones, or driverless trucks, and can be as small as a thumb drive to the size of a train. All of these things communicate with each other without the need for human interaction. This spider web of connectivity is fascinating but poses serious danger to information security.

Why does IoT security matter?

The ubiquity of smart devices is a major consideration for cybersecurity. A vulnerability in one of these IoT devices can lead to costly data breaches and affect an entire organization’s productivity. IoT security is also important as it keeps data secure. Smart devices can house large amounts of sensitive data, all of which falls under specific cybersecurity regulations. If this information is not secured, there could be legal ramifications if the data is compromised.

Exploring the IoT attack surface

A business’s attack surface is the sum of vulnerabilities that are currently present on its network, both physical and digital. This can be vulnerabilities from within endpoint devices (computers, tablets, etc.) or from the software and hardware used to conduct business. While each device is typically protected through security software, they are still apt to a series of added threats and vulnerabilities through their connection to the IoT. The Open Web Application Security Project (OWASP) provides a broad consensus of the current threats and vulnerabilities within the surfaces, which we have condensed into 3 main categories to outline.

Devices

Devices inevitably have vulnerabilities embedded within their memory systems, physical and web interface, network services, and firmware. This allows hackers to easily exploit systems within the devices' outdated components and insecure default settings with update mechanisms. When managing vulnerabilities throughout your network’s devices, continuous monitoring is essential.

Communication channels

Attacks can originate from the channels that connect IoT devices. This presents serious threats to the security of the entire system and creates a potential for spoofing and Denial-of-Service (DoS) attacks. These threats and attacks lay the foundation for an unstable network surface.

Applications and software

Each application and software presents risk and many web applications and APIs do not protect sensitive data adequately. This data can be anything from financial intelligence to healthcare information. A breach of these types of information can result in identity theft, credit card fraud, and exposure of confidential information all because a web application isn’t properly secured or patched on a consistent basis.

8 IoT threats and risks to be aware of

As long as the IoT continues to expand, the number of threats will continue to increase. Being able to identify and understand the different types of threats and vulnerabilities associated with the internet of things can significantly reduce the risk of a data breach at your organization. Let’s explore the top 8 IoT threats and risks:

1. Lack of physical hardening

The lack of physical hardening has always been a concern for devices within the internet of things. Since most IoT devices are remotely deployed, there is no way to properly secure devices that are constantly exposed to the broader physical attack surface. Devices without a secure location and the inability for continual surveillance allow potential attackers to gain valuable information about their network’s capabilities which can assist in future remote attacks or gaining control over the device. For example, hackers can facilitate the removal of a memory card to read its contents and access private data and information that may allow them to access other systems.

2. Insecure data storage and transfer

As more people utilize cloud-based communications and data storage, the cross-communication between smart devices and the IoT network increases. However, any time data is transferred, received, or stored through these networks, the potential for a breach or compromised data also increases. This is due to the lack of encryption and access controls before data is entered into the IoT ecosystem. For this reason, it is important to ensure the secure transfer and storage of data through robust network security management tools like firewalls and network access controls.

3. Lack of visibility and device management

Many IoT devices remain unmonitored, untracked, and improperly managed. As devices connect and disconnect from the IoT network, trying to monitor them can grow to be very difficult. Lack of visibility into device status can prevent organizations from detecting or even responding to potential threats. These risks can become life-threatening when we take a look into the healthcare sector. IoT pacemakers and defibrillators have the potential to be tampered with if not secured properly and hackers can purposefully deplete batteries or administer incorrect pacing and shocks. Organizations need to implement device management systems to properly monitor IoT devices so all avenues for potential breaches are accounted for.

4. Botnets

Botnets are a series of internet-connected devices that are created to steal data, compromise networks, or send spam. Botnets contain malware that allows the attacker to access the IoT device and its connection to infiltrate an organization's network, becoming one of the top business threats. They are most prominent in appliances that were not initially manufactured securely (smart fridges, for example). These devices are continuously morphing and adapting. Therefore, monitoring their changes and threat practices is necessary to avoid attacks.

5. Weak passcodes

Although intricate passcodes can prove to be secure for most IoT devices, one weak passcode is all it takes to open the gateway to your organization's network. Inconsistent management of passcodes throughout the workplace enables hackers to compromise your entire business network. If just one employee does not adhere to advanced password management policies, the potential for a password-oriented attack increases. Practicing good password hygiene is essential to ensure your business is covering all bases within standard security practices.

6. Insecure ecosystem interfaces

Application programming interfaces (APIs) are software intermediaries that allow two applications to talk to each other. With the connection of the two servers, APIs can introduce a new entrance for attackers to access a business's IoT devices and breach a network’s router, web interface, server, etc. It is crucial to understand the intricacies and security policies of each device in the ecosystem before connecting them to ensure complete network security.

7. AI-based attacks

While AI attacks have been around since 2007, the threats they present within IoT are becoming increasingly more prominent. Hackers now can build AI-powered tools that are faster, easier to scale, and more efficient than humans, to carry out their attacks. This poses a serious threat within the IoT ecosystem. While the tactics and elements of traditional IoT threats presented by cyber attackers will look the same, the magnitude, automation, and customization of AI-powered attacks will make them increasingly hard to battle.

8. Increased attack surface

As organizations continue to integrate cloud technology into daily processes, the number of devices connected to the network increase. This increases risk, making monitoring an even more challenging task. Without an IoT plan in place, the potential for a data breach increases alongside the number of unsecured devices. This is why it is important to have a plan in place that can effectively scale as IoT expands. Using device management systems and keeping employees up-to-date on best cybersecurity practices are two key parts of such a plan.
