How to protect PrestaShop from hacking – a practical technical guide

Online stores based on PrestaShop are a frequent target for attacks. This is mainly due to outdated modules, incorrect server configuration, and a lack of security monitoring. In this article, I show specific actions that can actually reduce the risk of hacking.

1. Updates – the absolute foundation

Most hacks involve stores running outdated engine or module versions. Each update fixes known security vulnerabilities.

• Update PrestaShop engine
• Remove unused modules
• Check changelog for security fix

2. Administration panel protection

The /admin panel should be additionally secured:

• Changing the default admin directory name
• IP blocking in .htaccess
• Two-Factor Authentication

3. Server Configuration

Many problems result from incorrect hosting configuration:

• Disabling PHP functions such as exec, shell_exec
• Enabled ModSecurity
• Current PHP version
• Correct file permissions (not 777!)

4. File and Malware Monitoring

Regular file scanning can detect backdoors and malicious scripts. Especially check for:

• directory /modules
• override
• upload
• root index.php

5. Backups

Backups should be performed automatically and stored off the production server. We offer the backup service in the basic package..

Summary

Securing PrestaShop is a process, not a one-time action. Regular audits and monitoring significantly reduce the risk of data loss and store reputation damage.
