The introduction of the Internet of Things has made great progress in many industries such as agriculture, utilities, manufacturing and retail. IoT solutions help increase productivity and efficiency in factories and workplaces.
In addition, IoT-driven medical devices have developed a networked and proactive approach to healthcare. Smart cities also use the Internet of Things to build interconnected traffic lights and parking lots to reduce the impact of traffic flow.
However, the impact of IoT security threats may be a major issue in the implementation of IoT. IoT security threats, such as DDoS, ransomware, and social engineering, can be used to steal critical data from individuals and organizations.
Attackers can exploit security vulnerabilities in the IoT infrastructure to perform complex network attacks. Such IoT security threats may be more enticing for consumers because consumers don't know about their existence and don't have the resources to deal with them. Therefore, business leaders must identify and address these security threats in order to provide consumers with quality products and services.
Eight Internet of Things security threats
No.1 botnet
A botnet is a network that combines various systems to remotely control a victim's system and distribute malware. Cybercriminals use command and control servers to control botnets to steal confidential data, access online banking data, and perform cyber attacks like DDOS and phishing.
Cybercriminals can use botnets to attack IoT devices connected to other devices such as laptops, desktops, and smartphones. The Mirai botnet has demonstrated the dangers of IoT security threats. Today, the Mirai botnet has infected about 2.5 million devices, including routers, printers and smart cameras. Attackers use botnets to initiate distributed denial of service attacks on multiple IoT devices.
After witnessing the impact of Mirai, some cybercriminals have developed several advanced IoT botnets that can launch sophisticated cyber attacks on vulnerable IoT devices.
No.2 Denial of service
A denial of service (DDoS) attack deliberately attempts to create a capacity overload in the target system by sending multiple requests. Unlike phishing and brute force attacks, attackers who implement denial of service are not planning to steal critical data.
However, DDOS can be used to slow down or disable services to compromise corporate reputation. For example, airlines that are subject to a denial of service attack will not be able to process ticket reservations, check flight status, and cancel tickets. In this case, the customer may switch to the services of other airlines. Therefore, a denial of service attack can undermine corporate reputation and affect its revenue.
No.3 Middleman (MITM)
In a middleman (MITM) attack, the hacker broke the communication channel between two separate systems and tried to intercept the information. The attacker controls its communication and sends illegal information to the participating systems.
This type of attack can be used to black into IoT devices such as smart refrigerators and self-driving cars. Man-in-the-middle attacks can be used to attack multiple IoT devices because they share data in real time.
With MITM, an attacker can intercept communications between multiple IoT devices and cause serious failures. For example, smart home accessories like light bulbs can be changed or turned on or off by an attacker using MiTM. Such attacks can have disastrous consequences for IoT devices such as industrial equipment and medical equipment.
No.4 Identity and data theft
A number of data breaches made headlines in 2018, causing data to be stolen by millions of people. Confidential information, such as personal information, credit and debit card vouchers, and email addresses are stolen from these data breaches.
Hackers can now attack IoT devices such as smart watches, smart meters, and smart home devices to get additional data about multiple users and organizations. By collecting this data, an attacker can perform more complex and detailed identity theft.
Attackers can also exploit vulnerabilities in IoT devices connected to other devices or enterprise systems, for example, hackers can attack vulnerable IoT sensors in an organization and access their business networks. In this way, an attacker can penetrate multiple enterprise systems and obtain sensitive business data.
No.5 Social Engineering
Hackers use social engineering to manipulate people to hand over their sensitive information, such as passwords and banking information. Alternatively, cybercriminals can use social engineering to access the system to secretly install malware.
Typically, social engineering attacks are performed using phishing emails, and attackers must develop compelling emails to manipulate others. However, in the case of IoT devices, social engineering attacks may be easier to perform.
IoT devices, especially wearable devices, collect large amounts of personally identifiable information (PII) and then develop personalized experiences for users. The device also utilizes the user's personal information to provide user-friendly services, such as ordering products online via voice control.
However, an attacker can access PII to obtain confidential information such as bank details, purchase history, and home address. This information allows cybercriminals to take advantage of the vulnerable IoT network to conduct advanced social engineering attacks against users, their families and friends. In this way, IoT security threats (such as social engineering) can be used to illegally access user data.
No.6 Advanced persistent threat
Advanced Persistent Threat (APT) is a major security issue for organizations. Advanced persistent threats are targeted cyber attacks that allow an intruder to gain unauthorized access to the network and remain undetected for long periods of time. Attackers aim to monitor network activity and steal critical data using advanced persistent threats.
Such cyber attacks are difficult to prevent, detect or mitigate. With the advent of the Internet of Things, a large amount of critical data can be easily transferred between multiple devices, and cybercriminals can target these IoT devices to gain access to personal or corporate networks. In this way, cybercriminals can steal confidential information.
No.7 ransomware
The ransomware attack has become one of the notorious cyber threats. In this type of attack, hackers use malware to encrypt the data needed for business operations, and the attacker only unlocks critical data after receiving a ransom.
Ransomware can be one of the complex IoT security threats. Researchers have demonstrated the impact of ransomware on intelligent thermostats. In this way, researchers have shown that hackers can raise the temperature and refuse to return to normal temperatures until they receive a ransom.
Similarly, ransomware can also be used to attack industrial IoT and smart home devices. For example, hackers can attack a smart home and send a notice to their owner to pay a ransom.
No.8 Remote recording
According to documents released by WikiLeaks, intelligence agencies are aware of the existence of "zero-day attacks" on IoT devices, smartphones and laptops. These documents suggest that security agencies are planning to secretly record public conversations.
Cybercriminals can also use these zero-day attacks to record conversations with IoT users. For example, hackers can attack smart cameras in an organization and record video clips of everyday business activities. In this way, cybercriminals can secretly obtain trade secret information. Such IoT security threats will also lead to serious privacy violations.
To mitigate their impact, business leaders need to understand the new landscape of IoT security threats and create a comprehensive cybersecurity strategy before their organizations use the IoT infrastructure.
To do this, they can hire a team of professional cybersecurity experts to handle all security issues, or if business leaders want to deploy cybersecurity technology independently, they can start by ensuring that all confidential data is encrypted and regularly secure the system. audit. In addition, enterprises can deploy modern technologies such as big data, blockchain and artificial intelligence to enhance network security.
