Running an ecommerce business is hard enough, even without having to deal with security threats.
Creating a secure environment for your customers is essential, but it’s particularly important at the moment, with money being tight and many choosing to shop online rather than risk in-person retail.
Ecommerce security isn’t just about protecting your customers, of course. A security breach could cost your business money, or risk serious reputational harm. In this guide, we’ll talk you through the main threats to be aware of, and how to keep your ecommerce business secure.
What are the Latest Ecommerce Security Threats?
Online stores are top targets for hackers because they have to manage a lot of sensitive customer information – including addresses, email, phone numbers, and bank information.
However, there are two main types of ecommerce threat – those that try to trick customers, and those which try to steal information and money from stores. Both threats are quite different, and require different types of responses.
Ecommerce phishing sites
These are the sites that try to trick customers into giving away their hard-earned money by pretending to be reputable.
Of course, these sites are nothing new. But, during the pandemic, the rates have soared. 84 million Americans were targeted with a phishing scam in the 12 months from October 2019-2020, with the ecommerce industry reporting a 66% increase in phishing attempts over the same period.
These sites will try and imitate yours, often using the same ecommerce hosting platforms that reputable businesses use. These sites often advertise heavily on Instagram and other social media platforms, before disappearing after only a couple of days. The domain names are always newly registered, and those registrants are normally hidden or anonymized.
E-skimming, sometimes known as Magecart, is a relatively new phenomenon – but its premise is pretty old-hat.
Hackers develop malware designed specifically to infect ecommerce websites. They sit behind the checkout page and collect all the information that customers enter. That could be anything from credit card details to addresses, phone numbers, emails, and passwords.
This malware can be hard to detect, and will hang around for a long time. Last year, London-based clothing company Páramo was infected by e-skimming software, which stole the names, addresses, card numbers, and CVV codes for more than 3,500 customers in eight months.
Even more concerning is that Páramo employed Security Metrics, an approved security scanning vendor, to scan the site for problems. Páramo only discovered the problem after 18 customers reported to PayPal that they had been victims of fraud.
Many small ecommerce businesses choose to use open-source software, and that’s easy to understand. After all, it’s cheap (even free), and can be modified easily to suit their needs.
However, because open-source software is available to everyone, it brings security risks to your company. The number of open source vulnerabilities doubled from 2018 to 2019, according to RiskSense. What’s more, RiskSense was looking at software that was being used in nearly 96% of all commercial codebases – meaning that your business was more than likely affected.
With open-source software issues taking an average of 54 days to be fixed, there is often ample time for hackers to exploit your company’s momentary weakness.
Plugins are often free, which makes them attractive to small ecommerce sites — WordPress, for example, has a host of plugins available which can help boost your site’s SEO performance or offer new features.
However, researchers at Sucuri regularly find bogus WordPress plugins which can cause serious grief for website users. Some redirect users to malicious sites, while others allow hackers to inject files straight into WordPress sites without the owner realizing. These could allow for skimming, or other criminal activities.
Ransomware is one of the most prevalent threats to any business in 2021, let alone ecommerce operations.
The premise is simple – hackers gain access to a business’s computer system or network, and then lock or encrypt files so that the business can’t access them. The attackers then charge a ransom to decrypt the files.
Ecommerce software vendor X-Cart suffered a ransomware attack in October 2020, after hackers are believed to have exploited a vulnerability in the third-party software that the company was using.
Businesses are attacked by ransomware every 11 seconds, on average, according to Cybersecurity Ventures – which is considerably more frequent than in 2016, when it was every 40 seconds.
While it's certainly lacking in the design department, here's what a ransomware attack might look like on your device:
Use SSL and ensure that you are PCI compliant
An SSL certificate provides authentication for websites and enables an encrypted connection to the internet. It’s an important trust signal for customers, too. Most website builders and ecommerce platforms actually come with an SSL certificate for your site, so you don't have to worry about getting one yourself. Large hosting providers will also help to make sure that your site has an SSL certificate.
PCI compliance, meanwhile, is essential for ecommerce businesses. The Payment Card Industry Data Security Standard (PCI DSS) is a set of requirements designed to ensure that companies process, store, and transmit credit card information in a secure environment. You’ll need to maintain firewalls and antivirus protections, protect passwords, protect cardholder data, encrypt any data you’ll be transmitting, and limit cardholder information to only those people who need to see it.
You’ll also need to restrict physical access to any sensitive cardholder information by keeping it in a secure location, as well as maintaining access logs of the people who look at it, and regularly scanning and testing for security vulnerabilities.
Ensure that you regularly purge customer data
You might be tempted to hold onto customer data indefinitely – what difference does storing details for two days make compared to two years if it all gets stolen?
However, by regularly removing old customer data, you’re limiting your business’s risk should there be a security breach.
Ensure strong passwords
Your weakest link might be your customers. If a customer’s details get leaked by hackers – which happens more often than you’d care to think – then those hackers could use that information to commit widespread fraud. You should ensure that your customers are using strong passwords and changing them regularly.
You should also get your employees to choose strong passwords and change them regularly, to prevent your internal systems from being compromised. You should also look to set up two-factor authentication for customers and employees.
A good password manager can easily help with that. Here's what your average password manager looks like, although many offer browser plug-ins for easy input.
Select a secure ecommerce platform
Using a hosted ecommerce platform is a great way to ensure that your site’s security is top-of-the-line. Providers such as Wix, Shopify, or Squarespace have far greater security resources at their disposal than your business ever would – and by using one of these platforms, you’ll be keeping your site secure.
These platforms aren’t open-source, meaning that there is less chance that you’ll encounter the same security risks that you’d get with WordPress.

Train your employees to be vigilant
Most security breaches happen as a result of human error – phishing breaches, for example, are almost always attributable to employees clicking a link in an email they didn’t realize was malicious.
Your employees should never give out sensitive information – whether it belongs to a customer or the business – over email or any other form of digital communication. You should always be looking to train and refresh your employees on information security.

However, that’s not to say that using a secure, hosted ecommerce platform will keep you safe forever. You will still need to be diligent in controlling your customer data, and who has access to it.
If you’re currently using an open source, self-hosted ecommerce platform, we would recommend switching. The security benefits are plentiful, but you’ll also gain access to more advanced analytics and marketing features – particularly automation features – which could save you time and make you a lot more money.
Final Thoughts — Improving Your Ecommerce Security
Improving your ecommerce security is remarkably easy – but perhaps even more remarkable is how many businesses aren’t fully secure.
Choosing a top hosted ecommerce provider will do a lot to improve your ecommerce security at a stroke. However, being diligent and vigilant about the information you keep and what you send out will also stand your business in very good stead.
