eCommerce Cybersecurity: 10 Hidden Threats Every Online Store Must Address

You might believe that your eCommerce business is not big enough to be on the radar of cybercriminals, but think again. According to experts, over 43% of cyberattacks targeted small and medium-sized businesses and online shops were among the hardest hit.

The modern-day digital storefront is not just a website; it's your reputation, your brand, and your bottom line. At Diginyze, we're familiar with the rhythm of new commerce and its vulnerabilities. That's why we're breaking down the top 10 security threats that are hitting e-commerce companies and how you can protect your business.

1. Phishing and Social Engineering

Cybercriminals are getting cleverer with expertly crafted phishing attacks against your employees or clients. Fake emails pretending to be legitimate payment processors or order confirmations can lead to stolen credentials and money loss.

Did You Know? 91% of all cyber-attacks start with a phishing email.

How to prevent it: Implement email filters, two-factor authentication, and regular employee education on identifying phishing schemes.

2. Payment Skimming (Magecart Attacks)

The most dangerous and malicious one, Magecart-style attacks inject code onto checkout pages to capture credit card data in real-time.

Example: British Airways paid $230 million in fines for a skimming attack that exposed 380,000 transactions.

How to prevent it: Enforce server-side detection tools, scan scripts on a regular basis, and minimize third-party integrations.

3. Ransomware

From taking down your entire site to holding customer databases hostage, ransomware is evolving to strike e-commerce directly.

Impact: The average ransom demand in e-commerce attacks grew to $1.5 million in 2025.

How to prevent it: Maintain regular cloud backups (Diginyze does it for you), isolate sensitive data, and deploy AI-driven eCommerce security.

4. Account Takeovers

Hacked or weak passwords allow hackers to hijack user accounts, place phony orders, and steal stored information.

Account takeovers are responsible for nearly 40% of all online fraud cases.

Prevention: Use strict password controls, offer biometric or OTP logins, and use AI-based detection of malicious activities.

5. Distributed Denial of Service (DDoS)

Drowning your site with malicious traffic not only knocks you offline but can also be a cover for deeper exploits.

How to prevent it: Employ CDN providers, rate limiting, and auto-scaling cloud architecture like we offer at Diginyze.

6. Man-in-the-Middle (MITM) Attacks

Since your customers are accessing your shop via unsecured Wi-Fi, attackers can intercept data transfers, such as payment information and login credentials.

How to prevent it: Use HTTPS across your site, implement TLS 1.3 encryption, and notify customers of secure browsing.

7. Third-Party Vulnerabilities

Plugins, ad trackers, and even payment processors can leave backdoors in your store if not heavily scrutinized.

Fact:
Around 60% of security breaches can be traced back to vulnerabilities in third-party tools or service providers.

How to prevent it:Use vetted vendors, check integrations quarterly, and cut down on plugin usage.

8. Credential Stuffing

Attackers use stolen credentials from other sites to steal user accounts on your site. Such attacks are scripted and usually remain undiscovered until damage is done.

Prevention: Enable CAPTCHA, flagging denied logins, and rate limiting.

9. Supply Chain Attacks

Hacking professionals attack your backend infrastructure through logistics providers, ERP systems, or API connectors.

How to prevent it: Vet your supply chain, encrypt APIs, and conduct regular penetration testing.

10. AI-Generated Fraud and Deepfakes

Today, cybercriminals use AI to generate sophisticated phishing emails, voice cloning, and scripting of fake transactions.

In 2024, incidents of deepfake-driven payment fraud surged by 300%.

How should you stop it: Fight AI with AI. Our Diginyze platform uses real-time behavior analysis and pattern recognition through AI to catch fraud before it causes harm.
