Top 10 common types of cyberattacks and threats you need to watch in the year 2023

A cyber-attack is an attempt by cybercriminals, hackers, or other digital enemies to gain access to a computer network or system, usually to alter, steal, destroy, or expose data.

Cyberattacks can target a variety of targets, including individual users, businesses, and even governments. The hacker's primary objective when attacking businesses or other organizations is to access sensitive and priceless firm resources, such as intellectual property (IP), customer data, or payment information. In this article, we have explained the top 10 common types of cyberattacks and threats you need to watch in the year 2023. Read to know more about common types of cyberattacks.

Top 10 Common Types of Cyberattacks in 2023:

There are many different types of cyberattacks in 2023, and they frequently occur now. Understanding the various cyberattack types makes it easier for us to protect our systems and networks from them. Here, we'll carefully examine the top ten cyber-attacks that, based on their scope, might either hurt a person or a significant organization.

1. Malware

Malware, often known as malicious software, is any program or code designed to harm a computer, network, or server. Malware is the most prevalent sort of cyberattack, owing to its broad definition, which includes trojans, ransomware, spyware, worms, keyloggers, bots, viruses, crypto-jacking, and any other type of malware assault that exploits software.

2. Phishing

Phishing is a sort of cyberattack that employs email, phone, SMS, social media, and social engineering techniques to trick a victim into sharing important information, such as passwords or account numbers, or into downloading a malicious file that would install viruses on their computer or phone.

3. Denial-of-Service (DoS) Attacks

A DoS attack is an aggressive, targeted attack that bombards a network with erroneous requests to stop commercial operations. Users are unable to do ordinary and important operations, such as accessing email, websites, online accounts, or other services operated by a compromised machine or network, during a DoS assault. Even though the majority of DoS attacks do not cause data loss and are typically resolved without the need for payment of a ransom, it still takes time, money, and other resources for the organization to recover crucial business activities.

4. Code Injection Attacks

Code injection attacks include an attacker inserting malicious code into a vulnerable machine or network to affect its behavior. Code injection attacks are classified into several types including SQL Injection, Malvertising, and Cross-Site scripting.

5. Supply Chain Attacks

A special sort of cyberattack known as a supply chain attack targets a reputable third-party provider of crucial supply chain software or services. Software supply chain attacks introduce malicious code into an app to infect all users, whereas hardware supply chain attacks compromise physical components to achieve the same goal, and software supply chains are particularly vulnerable.

6. Spoofing

Spoofing is a technique in which a cybercriminal masquerades as a known or trusted source. By doing so, the adversary gains access to the target's systems or devices, with the ultimate objective of stealing information, extorting money, or putting malware or other malicious software on the device.

7. DNS Tunneling

DNS Tunneling is a sort of cyberattack that uses domain name system (DNS) queries and responses to circumvent typical security measures and send data and code across the network. Once infected, the hacker has complete command-and-control capabilities. This tunnel allows the hacker to distribute malware and/or harvest data, IP addresses, and other sensitive information by encoding it bit by bit in a succession of DNS answers.

8. Insider Threats

IT teams who are only focused on identifying external threats are only getting half of the picture. Insider threats are internal actors, such as current or former employees, who pose a risk to a company because they have direct access to sensitive data, company network, and IP address as well as knowledge of business processes, company policies, or other information that could aid in the execution of such an attack.

9. Identity-Based Attacks

According to CrowdStrike's statistics, 80% of all breaches employ compromised identities and might take up to 250 days to detect. Identity-based assaults are exceedingly difficult to detect. When a valid user's credentials have been compromised and an adversary is masquerading as that user, traditional security procedures and tools can make it impossible to distinguish between the user's regular conduct and that of the hacker.

10. IoT-Based Attacks

An Internet of Things (IoT) attack is any cyberattack that targets an IoT device or network. Once attacked, the hacker can take control of the device, steal data, or join a botnet of infected devices to perform DoS or DDoS attacks.
