Generally, extensions and themes are vulnerable to XSS (Cross-Site Scripting) attack. It is a code injection attack in which attacker injects malicious JavaScript to the browser of your users.

Joomla sites can also be hacked through SQLI, stands Structured Query Language Injection. In this type of attack, the hacker injects SQL command into the database of your site and gains access to valuable information like visitor’s login credentials. If your website has been hacked, you can follow the steps mentioned below to fix it.

1. Identify the nature of Hack

First of all, scan your Joomla site to detect the locations of malicious payloads and malware. With this, check for any modified files, including the primary files. You can check them manually through SFTP. Once you find the hack, whether it is done SQLI or XSS, you need to jump on the next step quickly.

2. Cleanup the Database

An SQL injection keeps the potential to create new database users. Check for any new user in your database and if you find any rogue user, immediately deleted it by using SQL statement ‘Drop User’. With this restrict the database permissions for that new user. This action helps you sanitize the database of your site and keeps the potential to avoid future injections.

3. Secure the Server

  • Once you find the rogue file, exchange it with the new file.
