Most Common Types of Cyber Attacks in 2023

Here below we have mentioned all the common types of cyber attacks that occurred in 2023:-

Malware

Phishing

Denial-of-Service (DoS) Attacks

Code Injection Attacks

IoT-Based Attacks

Identity-Based Attacks

Supply Chain Attacks

Spoofing

Insider Threats

DNS Tunneling

Now let’s discuss the common types of cyber attacks in 2023:-

Malware

Malware refers to malicious software designed to harm or exploit computer systems, services, and networks, aiming for data extraction by cybercriminals for financial gain.

It targets various sensitive information like:-

Finances

Healthcare records

Emails

Passwords

Personal identification numbers

Banking details

Credit card numbers

Debit card numbers

Besides this, the malware also targets government and corporate sites as well for the following two key purposes:-

Data theft

Operational disruption

Here below, we have mentioned all the types of malware:-

Viruses

Ransomware

Scareware

Worms

Spyware

Trojans

Adware

Fileless malware

Phishing

Phishing attacks trick victims for the attacker’s benefit, and it’s been performed mainly via emails, ranging from simple to complex and not only that even Phishing attacks are:-

Extremely low-cost

Effective

Attackers mimic trusted sources, using bait-like messages to trick victims. Besides this, Phishing attacks lead to:-

Malware

Identity theft

Data loss

Targeting personal information

Targeting business information

Threat actors exploit phishing to access accounts, compromise systems, and initiate major data breaches as well. Phishing often backs harmful actions like on-path and cross-site scripting attacks, usually via email or instant message.

Denial-of-Service (DoS) Attacks

Denial-of-service (DoS) attacks disrupt a device’s normal function to make it unavailable. This happens by flooding it with multiple requests, which causes the denial of service to users.

If the attack comes from various sources like a botnet, then it’s called a DDoS (Distributed denial-of-service) attack. In short, the DoS attacks overload a machine to deny additional requests.

DoS attacks typically fall into 2 categories, and here below, we have mentioned them:-

Buffer overflow attacks

Flood attacks

DoS uses one connection, and DDoS deploys multiple sources, often a botnet; however, the attacks share similarities, as the threat actors use one or many sources of malicious traffic.

Code Injection Attacks

Code Injection involves injecting code into an application, and with the help of this attack, threat actors exploit the poor handling of untrusted data.

Besides this, the lack of proper input/output validation often makes these attacks possible.

Code Injection is unrestricted by injected language functionality, like PHP. In contrast, Command Injection uses existing code to execute commands, often in a shell context.

Vulnerabilities vary in discoverability and exploitation difficulty. While the successful exploits may lead to:-

Confidentiality loss

Integrity loss

Availability loss

Accountability loss

Code Injection involves injecting code into an application, and with the help of this attack, threat actors exploit the poor handling of untrusted data.

Besides this, the lack of proper input/output validation often makes these attacks possible.

Code Injection is unrestricted by injected language functionality, like PHP. In contrast, Command Injection uses existing code to execute commands, often in a shell context.

Vulnerabilities vary in discoverability and exploitation difficulty. While the successful exploits may lead to:-

Confidentiality loss

Integrity loss

Availability loss

Accountability loss

Injection flaws are often found in:-

LDAP

Xpath

NoSQL queries

OS commands

XML parsers

SMTP headers

Program arguments

IoT-Based Attacks

Advancements in the technological world enabled wireless connectivity for several types of smart devices:-

Watches

Lights

While the Internet of Things (IoT) automates these devices, equipped with sensors to collect and relay data for:-

Monitoring

Action

With the growing use and adaptability of IoT, cyber-attacks are actively targeted on connected devices. Though IoT devices enhance daily tasks but bring cybersecurity risks, especially for less-secured gadgets like-

Smart TVs

Wearables

Here below, we have mentioned all the common reasons why hackers target IoT devices:-

Weak passwords

Unsecured cloud storage

Unpatched software

Insecure network connections

Lack of encryption

Physical tampering

That’s for the secure operation of your IoT devices, it’s always recommended to stay vigilant and take all the necessary security measures.

Identity-Based Attacks

Nowadays, organizations face frequent cyber threats like Identify-based attacks, which are evolving rapidly and becoming:-

Complex

Sophisticated

These types of attacks are targeted by hackers who are actively looking for personal and sensitive data.

In telecom and beyond, Identity-Based Attacks are rising threats with significant consequences. Organizations must defend against various attacks like:-

Credential stuffing

Password spraying

Phishing

While regular password changes and the implementation of multi-factor authentication (MFA) will surely help to prevent these threats effectively.

In total, there are five types of Identity-Based attacks, and here below we have mentioned them:-

Credential Stuffing

Golden Ticket Attack

Kerberoasting

Man-in-the-Middle MITM Attack

Silver Ticket Attack

Supply Chain Attacks

Supply chain attack targets an organization’s weak links, exploiting trust in third-party vendors. It’s an island-hopping attack relevant across industries.

While this attack rising due to new tactics, it tampers with manufacturing processes to cause disruptions by exploiting the flaws in:-

Hardware

Software

These types of attacks are hard to detect, as they spread through trusted software, affecting organizations with many customers.

A supply chain attack aims to harm by infiltrating and disrupting a weak link in an organization’s system, often by targeting a vulnerable third-party supplier. Identifying the weakest point allows hackers to concentrate on the main target.

Spoofing

Spoofing fakes trusted sources in emails, calls, or websites, even using technical tricks like IP or DNS spoofing. It’s a sneaky way to:-

Snatch personal info

Spread malware

Dodge controls

Launch cyber attacks

So, successful attacks mean infected systems, data breaches, and revenue loss, spoiling an organization’s reputation. Traffic rerouting can flood the networks or even direct the users to malicious sites for the following two key illicit purposes:-

Information theft

Distribution of malware

Spoofing spans communication methods with varying technical expertise. It executes phishing scams to grab sensitive info.

While here below, we have mentioned the types of Spoofing attacks:-

Email Spoofing

Caller ID Spoofing

Website Spoofing

IP Spoofing

ARP Spoofing

DNS Server Spoofing

Insider Threats

Insider threats arise within an organization involving employees or partners with valid access. Whether intentional or accidental, they endanger the network security, which leads to compromised data integrity.

Besides this, most data breaches result from insider threats, as traditional cybersecurity neglects all the internal risks.

However, the familiarity insiders have with systems and vulnerabilities gives them an exclusive advantage. Tackling insider threats requires equal severity to external threats in cybersecurity strategies.

Here below, we have mentioned all the types of insider threats:-

Malicious Insider

Careless Insider

Negligent insider

Compromised insider

DNS Tunneling

DNS Tunneling encodes program data in DNS queries that enable the control of remote servers.

Besides this, it also demands the following things to fulfill its illicit goals:-

External network access

A compromised system

Control over a domain

Authoritative server for execution

DNS is crucial for internet navigation, as it interprets the domain names to IP addresses. That’s why organizations trust it, and it’s allowed through firewalls.

DNS tunneling exploits this trust and uses DNS requests as a command and control channel for malware. Inbound traffic commands the malware, while outbound exfiltrates data.

The flexibility of DNS allows for carrying sensitive info, making this attack vector simple and effective with various toolkits available.
