How to Prevent the Top 10 Most Common Cyberattacks
Cybersecurity is a pressing concern for businesses and individuals alike. With incidents like the Equifax breach making headlines, it’s clear that businesses and organizations must stay vigilant about online security.
Whether you want to beef up your cybersecurity skills or are responsible for safeguarding your organization’s networks, you need to know the most common cyberattacks and how to prevent them.
1. Phishing Attacks
Phishing attacks are one of the most common cyberattacks. According to Deloitte, approximately 91% of all cyberattacks start with a phishing email (Deloitte, 2020).
Phishing is a cyberattack that uses email or malicious websites to steal sensitive information, such as login credentials, credit card numbers, or account numbers. Attackers often pose as legitimate companies or individuals to trick victims into giving up this information.
There are many ways to prevent phishing attacks. Some of the most common methods include:
◉ Educating yourself and your employees about phishing attacks.
◉ Exercising caution with unsolicited emails, even if they appear to be from a trusted source; do not click on links or open attachments from unknown senders.
◉ Verifying the authenticity of websites before entering sensitive information.
◉ Using strong passwords and avoiding reused passwords for different accounts
◉ Implementing two-factor authentication where possible.
◉ Keeping your software and antivirus programs up to date.
2. Malware Attacks
In this 2022 Data Breach Investigations Report, Verizon states that 30% of data breach cases involve some type of malware (Verizon, 2022). Malware is a type of malicious code or software used to disrupt computer systems, steal data, or gain unauthorized access to a network. Common types of malware include viruses, worms, Trojan horses, ransomware, and spyware.
Preventing malware attacks requires a multilayered approach that includes:
◉ Technical controls, such as installing and maintaining antivirus and antimalware software.
◉ Nontechnical measures such as training employees on cybersecurity awareness and best practices as well as developing and enforcing strong security policies.
3. SQL Injection Attacks
SQL injection attacks occur when an attacker inserts malicious code into a web application to extract sensitive information from the database. The attacker can then use this information to gain access to the system or launch further attacks.
Some of the most common cyberattack strategies to prevent SQL injection include:
◉ Performing input validation to ensure all user input does not contain any malicious code.
◉ Configuring database permissions carefully to prevent unauthorized access to sensitive data.
◉ Using parameterized queries to avoid SQL injection vulnerabilities.
◉ Implementing security controls such as firewalls and intrusion detection systems.
4. Session Hijacking Attacks
Another common cyberattack, session hijacking, occurs when a hacker takes over a legitimate user’s session, usually by stealing the user’s cookies or session ID. Session hijacking attacks can be difficult to prevent, as they often exploit vulnerabilities at the network or application level.
Here are some steps you can take to reduce the risk of being hijacked:
5. DDoS Attacks
A distributed denial-of-service (DDoS) attack is a cyberattack in which multiple systems flood a target system with internet traffic, requests for information, or other data. The goal of a DDoS attack is to overload the target system so that it no longer functions properly or is unavailable to legitimate users.
Botnets often carry out DDoS attacks. These botnets are collections of infected computers controlled by an attacker (Brookes, 2022). The attacker will use them to send large amounts of traffic and data to the target system.
There are many ways to prevent DDoS attacks, including
6. Password Spraying Attacks
Password spraying is a type of cyberattack for which hackers use lists of commonly used passwords to try and gain access to multiple accounts. This type of attack often targets high-profile or unsecured accounts.
Some preventative measures to protect against password spraying are to maintain:
◉ Strong and unique passwords for all accounts.
◉ A password manager to keep track of passwords.
◉ Two-factor authentication whenever possible.
◉ Security mechanisms against phishing.
◉ Regular scans for vulnerabilities.
7. OnPath Attacks
In this common cyberattack activity, the attacker intercepts the communications of two victims, relaying messages between them and making them believe they are communicating directly. The attacker can eavesdrop on their conversation or modify the exchanged messages.
To reduce the risk of OnPath attacks:
◉ Always verify the identity of the person you are communicating with, even if you know them.
◉ Use encryption when possible and stay on guard against emails from unknown senders or emails that seem suspicious.
8. Ransomware
Ransomware is a type of malware that encrypts a victim’s files and demands a ransom payment to decrypt them. Ransomware attacks often involve phishing emails that contain malicious attachments, calendar invites, or links (CISCO Defense, 2022). Once opened, the attachment or link will download and install the ransomware onto the victim’s computer.
Preventative measures against ransomware include:
◉ Never opening attachments or clicking on links from unknown or untested sources.
◉ Keeping your antivirus and antimalware software up to date.
◉ Having a reliable backup solution in place so that you can recover your files in the event of an attack.
9. AI-Powered Attacks
Common cyberattacks carried out by AI-powered machines are among the most difficult to prevent. AI-powered machines can learn and evolve quickly, making it hard to keep up with their changing methods.
Examples of AI-powered attacks include deepfake videos and phishing attacks that use machine learning to become more realistic and believable (Fortinet, 2022).
Here are a few things you can do that will help to prevent AI-powered attacks
10. Zero-Day Attacks
A zero-day attack is a type of cyberattack that exploits previously unknown vulnerabilities in software or hardware (Hendler, 2022). These attacks take advantage of security vulnerabilities that have not yet been patched or made public.
Preventive measures against zero-day attacks include:

What Is Broken Access Control Vulnerability, and How Can I Prevent It?
Broken access control vulnerability is a type of security flaw that allows an unauthorized user access to restricted resources. By exploiting this vulnerability, attackers can circumvent standard security procedures and gain unauthorized access to sensitive information or systems. Broken access control vulnerabilities are often caused by weak authentication and authorization mechanisms, allowing attackers to gain illegitimate privileges. Prevention of such vulnerabilities is critical for preserving the security of your systems and data. In this blog post, we’ll discuss broken access control vulnerability and its prevention techniques.
What Is Broken Access Control Vulnerability?
One typical case of a broken access control vulnerability is an application that allows any user to view or edit sensitive data without authenticating first. An attacker could exploit this flaw to gain access to sensitive information or make changes to data without the proper permissions.
Another example of a broken access control vulnerability would be an application that doesn’t properly restrict access to certain functions based on a user’s role. For instance, an administrator account might have permission to add new users to the system, but a regular user account shouldn’t. However, if the application doesn’t restrict access to the function, a regular user could add new users to the system, potentially giving them administrator privileges.
Attackers may exploit these vulnerabilities to gain unauthorized access to sensitive data or make changes to data without the proper permissions. Organizations should implement adequate security controls to mitigate the risk of these vulnerabilities.
How to Identify a Broken Access Control Vulnerability
There are many attack vectors associated with broken access control vulnerabilities. However, some of the most common methods used to exploit these vulnerabilities include:
◉ Injection flaws: Injection flaws occur when untrusted input is injected into an application, resulting in unintended behavior. This can be exploited to gain unauthorized access to sensitive data or modify application data.
◉ Cross-site scripting (XSS): XSS flaws occur when untrusted input is included in web page output. Attackers can exploit this to execute malicious scripts in the user’s browser, resulting in session hijacking, cookie theft or other malicious activity.
◉ Broken authentication and session management: Broken authentication and session management flaws occur when an application fails to properly validate or protect information associated with user authentication and sessions. An attacker can exploit this to gain access to resources or data they shouldn’t have access to.
To prevent broken access control vulnerabilities from being exploited, it’s crucial to implement security measures such as input validation, proper session management, and authorization controls.
The Impact and Risk of Broken Access Controls
When it comes to access controls, organizations face several different risks if these controls aren’t properly implemented or maintained. One of the most common and potentially damaging risks is data breaches. If an attacker is able to gain access to sensitive data, they may be able to use this information for malicious purposes, such as identity theft or fraud. Additionally, data breaches can damage an organization’s reputation and lead to financial losses.
Another risk associated with broken access controls is compliance violations. Organizations subject to regulatory requirements, such as HIPAA or PCI DSS, must ensure access controls comply with these regulations. If an organization’s access controls aren’t up to par, they may be subject to fines or other penalties.
Finally, broken access controls can also lead to operational disruptions. When attackers can gain access to critical systems, they may be able to disable or damage them, leading to significant downtime and financial loss.
How to Prevent Broken Access Control
Access control is a security measure that determines who can access a particular area or resource. There are many different access control systems, but they all have the same goal: to keep unauthorized people from entering an area or using a resource (OWASP).
The most important thing is to have a well-designed system that considers all potential security risks. There are a few key steps you can take to help ensure that your access control system isn’t easily compromised:
Access Validation
The most foolproof way to prevent IDOR vulnerabilities and attacks is to perform access validation. If an attacker tries to tamper with an application or database by modifying the given reference, the system should be able to shut down the request, verifying that the user does not have the proper credentials.
In particular, web applications should rely on server-side access control rather than client-side so that adversaries cannot tamper with it. The application should perform checks at multiple levels, including the data or object, to ensure no holes in the process.
How to Become a Web Application and Security Professional
Security vulnerabilities, such as insecure direct object references, are a major problem for web applications. Fortunately, through fuzz testing and access validation techniques, IT security experts can detect and prevent IDOR vulnerabilities, helping safeguard applications from attack.
Do you want to become a web application and security professional yourself, preventing insecure direct object references and other vulnerabilities? Obtaining a cybersecurity certification such as EC-Council’s Web Application Hacking & Security (W|AHS) program is an excellent career move.
EC-Council is a leading provider of IT security courses, training programs, and certifications. The WAHS certification verifies that the holder knows how to hack, test, and secure web applications from existing and emerging security threats.
