How can these sites get hacked?

Joomla’s security features are well-known, but Joomla’s plugins and addons can expose it to attacks. Extensions and themes are generally vulnerable to XSS attack (Cross-Site Scripting). This is code injection, where malicious JavaScript is sent to your browser by an attacker.

SQLI stands for Structured Query Language Injection and can be used to hack Joomla sites. This attack involves the injection of SQL commands into your website’s database by the hacker. The hacker gains access to sensitive information such as login credentials and visitor details. You can fix issues on your website by following the steps below.

1. Identify the nature of Hack

To find malicious payloads or malware, scan Joomla. After scanning your Joomla site, look for modified files. These files can be checked manually via SFTP. You can quickly jump to the next step once you have found the hack, regardless of whether it is SQLI or XSS.

2. Clean up the Database

SQL injections can create new database users. You can check for new users in your database. If you find one, delete it immediately using the SQL statement “Drop User”. This will restrict the user’s database permissions. This will help you to sanitize your website’s database and prevent future injections.

3. Secure the Server

Even with strong security, spammy servers can lead to a Joomla hack. To ensure a secure server, remember the points below.

  • Keep an eye out for configuration issues.
  • Bloc the error messages that leak sensitive information
  • Make sure you have a firewall or other security solution installed.
  • All unused subdomains should be removed
  • If possible, close ports

4. Manage Permissions

To allow your users to surf in a safe environment, it is important to grant permission to all files and folders. When setting file permissions, you should keep these points in mind:

  • Users can upload images in.JPG instead of.php or.html.
  • The most sensitive file in a database is the ‘.htaccess’ file. You must ensure that no user can modify these files.
  • You must ensure that no one can overwrite your PHP files.

5. Modified Files in Joomla

By injecting malicious content onto your website, an attacker can create a new installation. If you don’t have a backup, you can either compare your files with the backup or search all Joomla files on Github. Follow the below steps to compare your files.

  1. Make a directory called Joomla and then switch it over
  2. Use the widget command to download Joomla files from Github
  3. Extract the file you downloaded.
  4. Then, you can compare public_html and the extracted content.
  5. Exchange the file with the new one once you have found the file in question.

6. Check Logs

System logs give you a clear picture about the attack because it tracks everything that happens on a site. Hackers can also create new admin accounts. Follow these steps to detect suspicious users.

  1. Click on Manage in Joomla Dashboard.
  2. Check for suspicious users or users who have recently registered.
  3. Remove all unknown users.
  4. Notify the server log location, and then check the logs for SQLI, XSS, etc.
