In today’s digital age, cyber attacks are becoming increasingly common and sophisticated. Cyber criminals are constantly finding new ways to target individuals and organizations, stealing sensitive information and causing significant damage.
From malware and phishing attacks to ransomware and denial of service (DoS) attacks, there are many different types of cyber attacks in existence. As a result, it is essential to understand the different types of cyber attacks and how they work in order to protect yourself and your business. In this blog, we will discuss the top 20 most common types of cyber attacks.
What is a Cyber Attack?
A cyber attack is a deliberate effort to disrupt or damage a computer network or system through the use of malicious software or other forms of digital infiltration. These attacks can take many forms, including phishing scams, malware, denial-of-service attacks, and backdoor access. Cyber attackers may be hackers seeking financial gain, activists pushing a particular agenda, or nation-states with political or military objectives. Cyber attacks pose a significant threat to organizations of all sizes, as they can result in financial losses, reputational damage, and legal repercussions.
Top 20 Most Common Types of Cybersecurity Attacks
Birthday Attack
A birthday attack is a type of cyber attack that exploits the probability of a collision between two randomly chosen numbers. This attack is named after the birthday paradox, which states that in a group of only 23 people, there is a 50% chance that two individuals share the same birthday.
In the context of cryptography, a birthday attack can be used to break hash functions, which are used to ensure data integrity and prevent tampering. This attack works by generating a large number of random inputs and calculating their hash values. By comparing these values, an attacker can find a collision, where two inputs have the same hash value.
Once a collision is found, the attacker can exploit it to bypass authentication schemes or create fake digital signatures. Cryptographic systems that are vulnerable to birthday attacks need to use stronger hash functions and other security measures to prevent such attacks.
Brute force attack
In the world of cybersecurity, a brute force attack is a common method of breaking through a password-protected system by guessing passwords repeatedly until the correct one is found. It’s a relatively simple attack, but it can be effective if the password is weak or easily guessable.
In a brute force attack, an attacker will use specialized software or a script to systematically try every possible combination of characters until the correct password is found. This can take a lot of time, depending on the length and complexity of the password. Attackers can use strategies such as a dictionary attack or a hybrid attack to increase their chances of success.
DoS and DDoS Attacks
DoS (Denial of Service) and DDoS (Distributed Denial of Service) attacks are two types of cyberattacks used to disrupt the normal functioning of a computer system or network. In a DoS attack, an attacker sends a large number of requests or data packets to a server or network with the goal of overwhelming and incapacitating it. This can cause the system or network to crash or become unavailable for legitimate users.
On the other hand, a DDoS attack involves multiple computers, known as a botnet, working together to launch a coordinated attack on a single target. This type of attack is more powerful and difficult to mitigate than a traditional DoS attack, as it can involve thousands or even millions of devices.
DNS Spoofing
DNS (Domain Name System) is a critical component of the internet infrastructure and is responsible for translating website names into IP addresses that computers can understand. DNS spoofing is a malicious attack where a hacker intercepts the communication between a user’s computer and a DNS server, and replaces the genuine IP address with a fake one.
The purpose of a DNS spoofing attack can vary. In some cases, it is used to redirect traffic to a fake website where the hacker can steal sensitive information such as login credentials or financial details. In other cases, the hacker may use this technique to distribute malware or launch a distributed denial of service (DDoS) attack.
Drive-by Attacks
A drive-by attack is a type of cyberattack in which a user’s computer is compromised simply by visiting a website that has been infected with malicious code. The attacker takes advantage of vulnerabilities in the user’s web browser or other software to download malware onto the user’s computer without their knowledge or consent.
Drive-by attacks are often carried out through ads or pop-ups on legitimate websites that have been compromised by an attacker. These ads or pop-ups may appear to be harmless, but they contain code that is designed to exploit vulnerabilities in the user’s web browser or other software.
Once the malware is downloaded onto the user’s computer, it can be used to steal sensitive information, such as login credentials and financial data, or to launch further attacks against other computers on a network. Drive-by attacks can be difficult to detect and prevent, as they often rely on unknown vulnerabilities in software that have not yet been patched by the vendor.
Eavesdropping Attacks
An eavesdropping attack is a type of cyber-attack where an unauthorized party intercepts communications between two or more individuals. This type of attack can occur via various mediums, such as emails, text messages, and phone calls, and can result in the theft of sensitive and confidential information.
Eavesdropping attacks are a significant threat to companies and individuals who value their privacy and data security. The attackers can use the stolen information for identity theft, financial fraud, and even corporate espionage.
Insider Threats
An insider threat refers to a security risk that originates from within an organization. This could be an employee, contractor, or even a business partner who has authorized access to sensitive company information, systems, or resources. Insider threats can take many forms, including theft of intellectual property, sabotage, fraud, or unauthorized disclosure of confidential data.
Malware Attack
A malware attack is a type of cyber attack in which malicious software, or malware, is used to infect a computer system or network. The malware is typically designed to cause harm to the targeted system, steal sensitive information, or gain unauthorized access to the network. Malware attacks can take many forms, including viruses, worms, Trojan horses, and ransomware.
Once the malware has infected a system, it can cause a wide range of problems, including data theft, system crashes, and network downtime. Malware attacks can also be used to spread further infections throughout a network or system. This makes it critical for organizations to take appropriate measures to protect their systems against malware attacks.
MITM Attacks
A MITM (Man-in-the-Middle) attack is a type of cyber attack where an attacker intercepts and alters communication between two parties without their knowledge or consent. The attacker essentially positions themselves between the two parties and intercepts the communication as it passes through. In doing so, the attacker can access sensitive information, such as login credentials or financial details, and can also manipulate the communication in order to redirect or block messages.
MITM attacks can take various forms, including DNS spoofing, IP spoofing, and session hijacking. One common example of a MITM attack is when a user connects to a public Wi-Fi network and an attacker intercepts the communication on that network.
Password Attack
In the world of cybersecurity, a password attack is a common form of hacking that involves attempting to gain unauthorized access to a computer system or network by cracking the password used to safeguard it. Password attacks come in many forms, ranging from simple brute force attacks where a hacker attempts to guess a password through trial and error, to more sophisticated methods such as dictionary attacks, where the hacker uses a precompiled list of commonly used passwords or social engineering strategies to guess the password.
Phishing Attacks
In the world of cybersecurity, the term “phishing” refers to a type of social engineering attack that is designed to trick a user into divulging sensitive information or performing a harmful action. Phishing attacks typically involve an attacker sending an email or message that appears to be legitimate (e.g. from a trusted source like a bank or a business) but is actually a fake, designed to trick the recipient into providing their login credentials, credit card information, or other sensitive data.
Phishing attacks can be highly effective because they often rely on social engineering tactics that take advantage of human nature – such as exploiting a user’s curiosity, sense of urgency, or fear of missing out. Some common examples of phishing attacks include emails that ask the user to reset their password, click on a link to update their account information, or confirm a suspicious transaction.
Ransomware
Ransomware is a type of malicious software that criminals use to gain access to a victim’s computer network or files, encrypt them, and then demand payment in exchange for the decryption key needed to unlock the files.
Many ransomware attacks today are executed through phishing emails, where the attacker sends an email that appears to be from a legitimate source, such as a bank or other financial institution. Once the victim clicks on a link or downloads an attachment, the ransomware program is activated and quickly spreads throughout the network. The consequences of a ransomware attack can be devastating, ranging from data loss to reputational damage to financial loss from payment of the ransom.
Session Hijacking
Session hijacking refers to the act of taking control of a user’s active session on a web application by stealing the session ID. This allows the attacker to essentially become the user, gaining access to all of their sensitive information and resources that were previously protected by the user’s session.
Session hijacking can occur through a variety of means, including exploiting vulnerabilities in the server software or the user’s browser. This makes it a serious threat to the security of any online business or organization that collects user data.
Spear-phishing Attacks
Spear-phishing attacks are a type of cyber-attack that involves targeted emails, phone calls or text messages that are designed to lure individuals into providing sensitive information, such as login credentials or financial information. Unlike regular phishing attacks that are sent to large groups of people in hopes of catching a few unsuspecting victims, spear-phishing attacks are highly targeted and often impersonate trusted sources, such as executives or IT administrators.
Spear-phishing attacks have become a growing concern for businesses due to their potential to cause severe damage, both financially and reputation-wise. They often rely on social-engineering tactics, where the attacker uses personal information about the targeted individual to gain their trust and convince them to take action.
SQL Injection Attack
A SQL injection attack is a form of cyber attack that targets web applications which rely on a database to store and retrieve information. Typically, attackers exploit vulnerabilities in the web application code to inject malicious SQL commands into the database. These commands can have devastating consequences, such as data theft, unauthorized access to sensitive information, and even complete compromise of the system.
The main goal of a SQL injection attack is to gain access to or manipulate sensitive data in a database, such as credit card information, user credentials, or other sensitive information. Attackers can also use SQL injection to modify or delete data, or even gain control of the entire system.
Preventing SQL injection attacks is crucial for the security of any web application. This involves ensuring that all user inputs are properly validated and sanitized before being processed by the database. Additionally, database access should always be limited to the minimum necessary for the functionality of the application.
Trojan Horses
As a cyber security professional, it is important to understand the various forms of attacks that can be used by hackers to access an organization’s data. One such attack is the Trojan Horse, named after the infamous symbol of deceit in Greek mythology.
A Trojan Horse is a type of malware that is designed to enter a system disguised as a harmless or even desirable software program. Once inside, the Trojan can execute various malicious activities such as stealing sensitive data, installing other malware, modifying or deleting files, or even taking over the entire system.
Trojans can be delivered through email attachments, downloads from untrusted websites, or even through social engineering tactics. They can be difficult to detect as they often disguise themselves as legitimate software programs.
Whale-phishing Attacks
Whale-phishing attacks, also known as whaling attacks, are a type of targeted phishing attack that specifically targets high-level executives or individuals with access to sensitive information. Unlike regular phishing attacks that cast a wide net in the hopes of catching as many victims as possible, whale-phishing attacks are carefully crafted to appear legitimate and are tailored to the specific target.
These attacks often come in the form of emails that appear to be from a trusted source, such as a senior executive or a business partner. The email may contain a request for sensitive information or may ask the recipient to click on a link that downloads malware onto their computer. In some cases, the email may even ask the recipient to transfer money or make a payment on behalf of the company.
Web Attacks
A web attack is an intentional, malicious action taken to exploit vulnerabilities in a web application or website. These attacks can be carried out in various ways, including hacking, phishing, or injecting malicious code. They can result in a range of negative consequences, such as data theft, financial loss, and damage to a company’s reputation.
Web attacks typically target weaknesses in a website’s security features, such as outdated software, weak passwords, or insufficient security protocols. Attackers may use automated tools to scan for vulnerabilities or employ more sophisticated methods, such as social engineering, to manipulate users and gain access to sensitive data.
XSS Attacks
Cross-Site Scripting (XSS) is one of the most common web application security vulnerabilities affecting both large and small companies. An XSS attack involves an attacker injecting malicious code into a web page, which is then displayed to a victim’s browser. When the victim visits the page, the code is executed in their browser, potentially exposing sensitive data or compromising their system.
There are different types of XSS attacks, including stored XSS, which involves malicious code being stored on a server and executed whenever a user accesses the page, and reflected XSS, where the malicious code is injected into a URL parameter and executed when the victim clicks the link.
