With the sheer number of WooCommerce stores out there, it’s no surprise they’re a prime target for hackers. Cybercriminals know exactly where to look – outdated plugins, weak passwords, unpatched vulnerabilities – and they know how easy it is for store owners to overlook these risks.

The fallout goes well beyond losing sales to some downtime. Think of the trust that evaporates when customers realise their data is at risk. Add to that a recovery process that could prove expensive, time-consuming, and maybe, just too much for your business to bounce back from.

If you’re serious about safeguarding your WooCommerce store, join us as we cover actionable tips on spotting potential attacks and protecting your site from security threats!

Types of WooCommerce vulnerabilities

Here are some of the most common threats hackers exploit to gain access to your eCommerce store:

  • Cross-Site Scripting (XSS) vulnerabilities allow hackers to inject malicious scripts into a website. This could enable attackers to steal session cookies, log in as users, or inject harmful content, potentially compromising customer accounts and sensitive data.
  • PHP object injection occurs when attackers inject serialised PHP objects into a website’s code. Hackers could use this to manipulate server functions, access sensitive data, or execute arbitrary code, leading to unauthorised control of the site.
  • File deletion vulnerabilities let hackers exploit insecure file upload mechanisms to delete crucial files from the server. This could result in the loss of product images, customer data, or other essential files, causing disruptions or data loss.
  • Brute force attacks involve hackers repeatedly trying different username and password combinations until they succeed. In WooCommerce stores with weak or default login credentials, attackers could gain unauthorised access to the site and potentially steal customer data or process fraudulent transactions.
  • SQL injection allows attackers to insert malicious SQL queries through input fields, potentially manipulating the website’s database. This could lead to unauthorised access to customer information, the deletion of product data, or even full control of the database.

Avoiding WooCommerce skimming attacks

Skimming attacks in WooCommerce involve fraudsters stealing sensitive customer information, like credit card details, during online transactions. Attackers use malicious scripts or fake forms to secretly collect this data without the customer’s knowledge.

One increasingly common method is through Magecart-style attacks, where hackers insert hidden code into a website that looks legitimate but is actually designed to capture and send sensitive information to the attackers.

The term “Magecart” comes from the popular eCommerce platform Magento, which was targeted in early skimming attacks. Over time, Magecart has expanded to target other platforms, including WooCommerce.

What makes these attacks tricky is that the malicious code often hides behind trusted websites or domains, making it harder for security systems to spot. This tactic takes advantage of a site’s reputation, tricking both customers and security tools into trusting the site while stealing data in the background.

If you think this is some far-off threat, let’s put things into perspective: In 2023, an ethical hacker published a report about one such vulnerability hiding in the WooCommerce Payments plugin (now WooPayments) which was running on 600,000 websites at the time.

The only way to prevent these types of attacks is by keeping everything on your website updated and monitoring for suspicious activity using a tool like Shield Security PRO.

Signs your WooCommerce store may have been hacked

If you suspect that your WooCommerce store might have been compromised, look for these key signs that could indicate a hack:

  • Customers report unauthorised charges or discrepancies in their orders, which could suggest attackers have gained access to your payment system and are stealing credit card information or making unauthorised charges.
  • Product prices or descriptions change unexpectedly, a sign that hackers might have altered your listings to include malicious links, redirects, or other disruptions to your store.
  • Orders appear in your system that you didn’t create or recognise, indicating that unauthorised individuals may have gained backend access and are placing fake orders or using your store for fraudulent purposes.
  • The checkout page looks unfamiliar or missing payment options, which may suggest a skimming attack where malicious scripts have been injected to capture sensitive payment details.
  • There is an unusual spike in traffic from suspicious or foreign IP addresses, which could be a sign of a brute force attack or an attempt to exploit vulnerabilities in your WooCommerce store.

Responding to a hack: Step-by-step WooCommerce recovery plan

If you’ve determined conclusively that your eCommerce store has been hacked, you need to swing into action immediately:

  1. Isolate your site from the internet to prevent further damage. Taking your store offline immediately minimises the risk of further data breaches, stopping hackers from exploiting the vulnerability or stealing more data.
  2. Identify the source of the attack by checking logs for unusual activity. Analysing server and plugin logs can help pinpoint the entry point, whether it’s a compromised plugin, weak admin credentials, or malicious code injection, allowing you to address the root cause.
  3. Update all passwords for admin, SSH, and database access. Resetting passwords ensures that attackers no longer have access to your system, protecting against further unauthorised logins or changes to your store.
  4. Run a full malware scan using security tools like Shield Security PRO. Scanning for malicious code allows you to identify and remove any injected scripts, backdoors, or malware that hackers may have left behind.
  5. Restore your store from a backup if possible. Reverting to a backup made before the attack occurred ensures that you can recover your store’s functionality and remove any malicious code or changes made by the hackers.
  6. Notify customers and authorities about the breach. Transparency with your customers builds trust, while informing authorities or relevant agencies may help with an investigation and any potential legal requirements.
  7. Strengthen your security measures post-attack by updating all plugins, using strong passwords, enabling two-factor authentication, and implementing a Web Application Firewall (WAF) to prevent future attacks.

How Shield Security PRO safeguards your WooCommerce business

As always, prevention is better than cure. Your WooCommerce store is better served by a proactive security strategy like the one offered by Shield Security PRO:

  • Bad bot protection and IP blocking prevent malicious bots from interacting with your WooCommerce store. They counter automated attacks that could target sensitive areas like login pages, checkout forms, or customer data, reducing the risk of brute-force or credential-stuffing attacks.
  • An adaptive anti-malware engine, MAL{ai}, that’s always learning and identifying patterns so it’s more capable of reacting to emerging threats rather than waiting for a security team to get its act together after the damage is already done.
  • Two-factor authentication (2FA) adds an extra layer of security to your WooCommerce admin panel by requiring a second form of authentication, such as an app-based code or email. This helps prevent unauthorised access even if login credentials are compromised.
  • Admin area lockdown restricts access to sensitive settings behind a PIN. This feature, called Security Admin, means someone who could get past 2FA, authorised or otherwise, still couldn’t make significant changes to the site unless they’re meant to.
  • User account protection features include automatic user suspension and manual user suspension options. They help protect your WooCommerce store by getting rid of suspicious or unauthorised user accounts, which also reduces the risk of fraudulent activities or chargebacks.
  • Automatic file repair restores any compromised core files to their original, secure state. This feature automatically repairs files that may have been altered during an attack, ensuring your store functions properly without manual intervention.

WooCommerce security best practices

To strengthen your WooCommerce store’s security, follow these best practices to prevent and mitigate potential attacks:

  • Regularly create and test backups of your WooCommerce store using a tool like ShieldBACKUPS. Backing up your entire store, including databases, product information, and customer data, ensures that you have an up-to-date copy to restore from if your site is compromised.
  • Use separate SSL certificates for your checkout pages to secure sensitive transactions. A dedicated SSL for the WooCommerce checkout process ensures that customer data is encrypted during payment processing, offering added protection against man-in-the-middle attacks.
  • Restrict access to the WooCommerce REST API by limiting which users and IP addresses can access it. WooCommerce’s REST API can expose sensitive store data if not properly protected, so disable or tightly control access to prevent unauthorised interactions with your store’s data.
  • Regularly review WooCommerce logs for suspicious activity like failed payments or changes to shipping addresses. WooCommerce logs provide insights into abnormal transactions or payment failures, which can be early indicators of fraudulent activity or attempted hacks.
  • Disable guest checkout for high-risk products such as digital goods or high-value items. Requiring customers to register before purchasing can help mitigate fraud, as it provides better tracking and identification of suspicious transactions.
  • Segment payment gateways by risk level to reduce exposure. Use different payment gateways for high-risk products or regions, ensuring that sensitive transactions are processed using the most secure methods, while minimising the impact of a potential breach.
