How Websites Are Hacked in 2024 and Useful Tips on How to Prevent It

Understanding how websites get hacked is crucial for anyone who manages or uses online platforms. This article aims to clearly explain the main methods hackers use to compromise websites and provide practical advice on how to prevent such security breaches.

By familiarizing yourself with these common vulnerabilities and implementing the safeguards discussed, you can significantly reduce the risk of your website falling victim to an attack.

Why Are Websites Hacked

Hackers are driven by various motivations, each carrying its own threats to website owners.

Value of Data

Private data such as financial records, login credentials, and other sensitive information collected on web servers are highly sought after by cybercriminals.

Confidential information, when stolen, can be trafficked on the dark web, employed in identity theft, or used for blackmail purposes.

A website’s size does not diminish the value of its confidential data. Any site that stores private information can attract a hacker’s interest.

Financial Gain

Financial gain is another strong motivator for hackers. They may deploy ransomware to lock website owners out and extort money to restore their access.

Another less flashy approach is to discretely break into your system to siphon funds by intercepting financial transactions between your business and customers.

Political and Ideological Reasons

Some hackers are driven by a desire to make a statement by disrupting governmental or corporate operations.

These cybercriminals, often referred to as hacktivists, may not always seek personal gain but can cause substantial damage and loss of public trust in targeted organizations.

How Websites Are Hacked

Let’s look at some of the most common hacking techniques attackers use to access a website.

Malware and Backdoors

Malware is a type of malicious software that infiltrates websites and computer systems, often exploiting security weaknesses such as outdated software, insecure coding practices, or third-party integrations. Once infected, they can cause frequent website crashes and security breaches.

A backdoor is an access control software vulnerability that can allow attackers to gain unauthorized access to your website. These can be flaws in the code or malware infections, allowing attackers to mislead login procedures to hijack the site.

Regularly scanning your site for malware is an essential security practice. Scans should be thorough and frequent, using reliable and updated security tools to identify the latest threats.

Here are a few well-regarded malware detection tools:

  • Sucuri SiteCheck. A free website scanner that can detect various types of malware and security issues. They also offer paid features like website backdoor removal and firewall protection.

SQL Injection

An SQL injection (SQLi) is a type of cyber-attack where a hacker slips malicious code into a website’s database to alter or steal confidential data.

The attacker usually manipulates text input fields, like those used for login or search functions, to send SQL commands to the database to trick it into performing an unauthorized action, like providing direct access to the system.

For example, instead of entering a username, hackers might enter a short SQL code such as ‘ or 1=1 — to override the conditions set on user access points to validate someone as an authenticated user.

SQL injection prevention relies on thorough verification and sanitization of all user inputs, ensuring that only legitimate data is processed. This is known as input validation.

Moreover, using parameterized queries – where SQL code is defined and user input is treated strictly as data, not executable code – can effectively neutralize SQL injections.

Social Engineering

Social engineering is a type of psychological manipulation where attackers exploit vulnerabilities in human behavior to convince them to install malicious software on their personal computers, upload malicious files to their internal network, divulge login credentials, or even provide direct access to restricted areas.

Here are some common social engineering attacks cybercriminals use:

  • Pretexting – attackers assume a false identity, often posing as trusted individuals like technical support staff or authority figures, to gain the victim’s trust and extract personal information or breach restricted systems.
  • Baiting – hackers leave enticing lures, such as USB drives in public places or malicious links on social media forums, persuading curious individuals to interact with them.
  • Quid pro quo – social engineers offer users something of value, such as a gift or a service, in exchange for personal information or entry into a restricted area.
  • Phishing – hackers craft deceptive emails that direct users to malicious websites that appear to be from legitimate sources, such as banks or credit card companies, tricking unsuspecting individuals into revealing their login credentials or other sensitive data.

Cross-Site Scripting (XSS)

Cross-site scripting is a security vulnerability that allows attackers to inject malicious scripts into web pages. It allows cybercriminals to steal user data, deface websites, or redirect visitors to harmful sites.

XSS attacks can occur in various forms, often exploiting vulnerabilities in user-generated content.

Common examples include:

  • Reflected XSS – malicious scripts are reflected back to the user’s web browser through URLs, error messages, or other dynamic content.
  • Stored XSS – scripts are injected into a website’s database and executed whenever the affected page is loaded.
  • DOM-based XSS – attackers inject scripts directly into a web page’s Document Object Model (DOM), exploiting vulnerabilities in JavaScript libraries or frameworks.

To effectively protect against XSS attacks, website developers and administrators must implement comprehensive security measures.

Key strategies include:

  • Input sanitization – properly validate and sanitize all user-supplied data before it is displayed or processed. This involves removing or escaping any potentially harmful characters or code that could be injected into the web page.
  • Content security policies (CSPs) – implement CSPs to define which sources can execute scripts on your website. This helps to restrict malicious scripts from being injected and executed.
  • Regular security audits – conduct regular security audits of your website’s code to identify and remediate potential XSS vulnerabilities.

Brute Force Attacks

Brute force attacks are a trial-and-error method hackers use to decode encrypted data such as passwords. This is done by systematically checking all possible password combinations until the correct one is found. Attackers employ automated tools to generate password combinations.

The use of strong and unique passwords ensures effective brute force protection. Avoid using easy-to-guess passwords such as birthdays, names, or common words.

Another defense measure is to implement account lockout policies, which freeze user accounts after a certain number of incorrect attempts.

Regular password updates are fundamental to avoiding security vulnerabilities. Periodically changing passwords disrupts an attacker’s ability to guess or crack your passwords through a brute force attack.

3. Learn to Identify Social Engineering Attacks

Social engineering attacks exploit human psychology rather than software vulnerabilities, yet awareness and vigilance are the most effective defenses against them.

Here are some social engineering awareness tips:

  • Verify contact information – carefully check the sender’s email and website for inconsistencies or spelling errors, and hover over links to see their actual destination before clicking.
  • Avoid unknown links and devices steer clear of plugging unknown USBs, clicking on unfamiliar links, and opening attachments from sources you don’t recognize.
  • Use two-factor authentication – 2FAs add a second verification step to your account, so even if someone gets your login credentials, they still won’t gain access to your account.
  • Keep updated – cybercriminals constantly develop new ways to perform malicious attacks, and being aware can help you spot and avoid them.
  • Install security software – use trustworthy security software for real-time protection against phishing attacks. Some of these tools also provide alerts for suspicious websites.

4. Perform Regular Software Updates

Regular software updates play a crucial role in securing websites, often including patches for security vulnerabilities discovered since the last version was released.

It is essential to ensure that all components of their website, including the content management system (CMS), plugins, and themes, are always up to date.
