Webshops and the Importance of Cybersecurity
A webshop is much more than a website: it is the meeting point of payment data, a customer database, order history and business processes. That is exactly why online stores are among the favourite targets of cybercriminals — regardless of whether they handle ten or ten thousand orders a day. In this article we look at why every webshop is a target, which types of attacks you should expect, and which basic security measures reduce the risk significantly.
Why is every webshop a target?
A common misconception is that "our webshop is too small to be attacked". In reality, the vast majority of attacks are not targeted but automated: thousands of bots scan the internet for known vulnerabilities, outdated plugins and weak passwords. From an attacker's point of view, every webshop is valuable, because it:
- Runs a payment process: manipulating card data and payment redirects brings direct financial gain to the attacker.
- Stores personal data: a customer database of names, email addresses, phone numbers and shipping addresses sells well on the black market and fuels further phishing campaigns.
- Enjoys customer trust: fake emails sent in the webshop's name get far more clicks from customers.
- Provides resources: a compromised server can be used for sending spam, crypto mining or launching further attacks — often without the owner noticing for months.
The most common threats
1. Outdated systems and plugins
Most successful webshop breaches are not sophisticated, targeted attacks but the exploitation of a long-known, unpatched vulnerability. For WooCommerce, PrestaShop or Magento based stores, plugins are the largest attack surface: a single outdated extension can be enough to compromise the whole system.
2. Malicious code in the checkout (web skimming)
In a web skimming attack (known from the infamous Magecart campaigns), the attacker injects a few lines of hidden JavaScript into the checkout page, silently forwarding the card details entered by the customer to the attacker's server. The webshop appears to work perfectly, which is why these infections can stay hidden for a long time.
3. Account takeover: brute force and credential stuffing
Attackers automatically try passwords on admin interfaces, and test email–password pairs leaked from other sites (credential stuffing). If an operator reuses the same password in multiple places, or picks a weak admin password, the attacker gets the keys to the entire webshop.
4. Phishing
Not only customers are targeted, but the webshop's staff as well: a fake "hosting provider" or "courier service" email can be enough for someone to hand over their login credentials. The human factor is the starting point of most security incidents.
5. Denial of service (DDoS)
The goal of a DDoS attack is to make the webshop unavailable — typically during the busiest periods (e.g. Black Friday), when every minute of downtime means direct revenue loss. It sometimes comes combined with extortion: the attacker demands money to stop the attack.
6. Ransomware
Ransomware encrypts the data on the server — from the product database to the orders — and demands a ransom. Without proper, separately stored backups, such an attack can paralyse the entire business.
What is at stake for the webshop owner?
- Direct revenue loss: no orders during downtime, while recovery costs time and money.
- GDPR consequences: if personal data leaks, the company must report the breach to the authority, and significant fines can be imposed.
- Loss of trust: a large share of customers never return to a webshop where their data was misused — the reputational damage is often bigger than the incident itself.
- SEO penalty: if Google detects malicious code on the site, it shows warnings in the search results or removes the site from its index — organic traffic collapses.
Essential security measures
The good news: the vast majority of attacks can be prevented with a few basic measures applied consistently.
- Regular updates: keeping the webshop engine, plugins, themes and server software up to date is the single most important line of defence.
- Strong passwords and two-factor authentication (2FA): every admin account should have a unique, long password and, where possible, two-factor login.
- Least privilege: everyone should only have access to what their job actually requires; access that is no longer needed must be revoked immediately.
- Automated, isolated backups: a backup is only worth anything if it is stored independently of the webshop and its restoration is tested regularly.
- HTTPS and security headers: encrypted connection across the whole site, plus modern browser protections (e.g. Content Security Policy).
- Web application firewall (WAF): filters out common attack patterns (SQL injection, XSS, bot traffic) before they reach the webshop.
- Logging and monitoring: without detecting suspicious login attempts, file changes and traffic anomalies, an attack is only discovered when it is already too late.
- Incident response plan: when trouble hits, you need to know within minutes who does what — who to call, what to shut down, and how to communicate with customers.
The human factor
Technical protection alone is not enough: regular, practical security awareness training for staff — how to spot a phishing email, what to do in case of suspicion — is at least as important as any firewall. Security is not a one-off project but a continuously maintained state.
Summary
Cybersecurity is not a luxury for large enterprises but a basic requirement of running any webshop. Attacks are automated and constant — the question is not whether they will try, but whether your webshop will be prepared. Applying the basics consistently reduces the risk to a fraction, and the remaining risk can be managed with expert assessments and continuous operational monitoring.
