Websites of all sizes are targeted by cybercriminals, with attacks often exploiting overlooked vulnerabilities rather than sophisticated flaws.
Understanding the most common threats and conducting regular website security checks can significantly reduce the risk of data breaches, downtime, and reputational damage.
1. Phishing Attacks
Phishing attacks use fake login pages or forms to trick users into sharing sensitive information. These attacks can damage user trust and expose customer data. They are often delivered via compromised links, cloned websites, or deceptive email campaigns that appear legitimate.
2. Malware Infections
Malware is often injected through compromised plugins, themes, or outdated software. Once installed, it can redirect visitors, steal data, or blacklist your site in search engines. In many cases, malware operates silently in the background, making detection difficult until performance or rankings are affected.
3. SQL Injection
SQL injection attacks target poorly secured databases by inserting malicious code into input fields. Successful attacks allow hackers to access, modify, or delete database information. These vulnerabilities often stem from inadequate input validation and outdated database configurations.
4. Cross-Site Scripting
XSS attacks involve attackers injecting harmful scripts directly into web pages viewed by users. These scripts can steal session data or redirect users to malicious sites. XSS vulnerabilities are commonly found in comment sections, search bars, and other areas that accept user input.
5. Distributed Denial-of-Service Attacks
DDoS attacks overwhelm websites with traffic, causing slowdowns or complete outages. While difficult to prevent entirely, website security checks can help assess server readiness, traffic filtering, and response strategies to minimise disruption.
