How to fix a hacked WordPress website

WordPress is one of the most popular content management systems (CMS) in the world, powering over 40% of all websites. Its popularity, however, makes it a common target for hackers and malicious actors.

What is WordPress Hacking?

WordPress hacking refers to unauthorised access to, or manipulation of, a WordPress website. Hackers often exploit vulnerabilities in outdated plugins, themes, or the WordPress core itself to gain access to the site. Once inside, they can cause a wide range of problems, from stealing sensitive information to defacing the website.

Common Methods of Hacking

1. Brute Force Attacks: This method involves repeatedly attempting to login to the WordPress dashboard using various username and password combinations until successful.
2. SQL Injection: Hackers can manipulate a site’s database through poorly secured forms or outdated plugins, allowing them to access or even control the site.
3. Cross-Site Scripting (XSS): This type of attack involves injecting malicious scripts into web pages viewed by other users, often aiming to steal information.
4. Phishing: By creating fake WordPress login pages, hackers can trick users into providing their login credentials.

Why WordPress Sites Get Hacked

• Outdated Plugins and Themes: Many WordPress hacks result from outdated or poorly maintained plugins and themes that contain known vulnerabilities.
• Weak Passwords: Simple and commonly used passwords provide an easy entry point for hackers.
• Lack of Security Measures: A failure to implement basic security measures like firewalls, SSL certificates, and regular updates can leave a site exposed to attacks.

Impact of Hacking

A hacked WordPress site can lead to serious consequences, including:

• Loss of sensitive user information.
• Damage to reputation and loss of trust among visitors.
• Potential legal liabilities.
• Search engine blacklisting, leading to a significant drop in traffic.
