🛡️ PrestaShop survival guide: tips to prevent viruses and attacks in 2026
Having an online shop on PrestaShop is a powerful tool for sales, but it also puts you in the sights of cybercriminals. A hack not only stops your income, it damages your reputation and your customers' trust.
After years of recovering critical shops at ByteChip, we have gathered the essential tips to make your eCommerce a fortress.
1. Keep your PrestaShop version up to date
Many hacks happen because of using obsolete versions (such as 1.6 or old versions of 1.7). Updates not only bring visual improvements, but critical security patches. If your version no longer has support, it is time to consider a migration.
2. The danger of "nulled" modules
The cheap turns out expensive. Installing modules or templates from unofficial sources (free or pirated) is the fastest way to introduce a virus or a backdoor into your server. Always buy from the official Marketplace or from trusted developers.
3. Protect the admin directory
Don't leave the door open. Renaming the /admin folder to something unique and hard to guess is the first step. We also recommend:
- Using passwords of more than 12 characters (combining symbols and numbers).
- Restricting access by IP if you always work from the same place.
4. Database cleaning
A common attack is code injection into the database. If you notice administrator users you did not create or orders with strange characters, it is a sign that they have got in. Carry out regular cleanups to remove orphan or suspicious records.
5. Google's "Site not safe" warning
If Google flags your website with the famous red screen, your sales will drop to zero. This is usually due to malware that redirects your customers to other websites. Acting fast is vital so your SEO does not sink for good.
🆘 Is it already too late and have you been hacked?
If you notice your PrestaShop is slow, products have disappeared or your customers complain about virus warnings, don't panic, but act now.
