Step-by-Step Guide to Preventing Ecommerce Fraud in 2024

Ecommerce fraud has become one of the most pressing challenges for online retailers. As digital commerce grows, so do the strategies and techniques that fraudsters use to exploit vulnerabilities in online stores.

In 2024, the costs associated with fraud, including lost revenue, chargeback fees, and reputation damage, are significant. Understanding the types of fraud affecting the ecommerce sector and adopting proactive measures is essential for maintaining customer trust and protecting business assets.

Step 1: Understand Common Types of Ecommerce Fraud

1. Credit Card Fraud

Credit card fraud remains one of the most common types of ecommerce fraud. Fraudsters use stolen card information to make purchases, leading to chargebacks and potential losses for businesses.

Often, this data is stolen through phishing scams, data breaches, or from the dark web. Implementing additional verification for high-value orders can help, along with monitoring for inconsistent billing and shipping addresses.

2. Account Takeover (ATO)

Account takeover involves unauthorized access to a user’s account, enabling fraudsters to make purchases using saved payment information. With the increase in credential stuffing attacks, where bots attempt thousands of login attempts using compromised credentials, ATO is a growing threat.

Businesses can mitigate this by implementing CAPTCHA systems and by tracking unusual login activities, such as multiple failed attempts or logins from unfamiliar locations.

3. Identity Theft

Identity theft occurs when fraudsters use someone’s personal information to create fake accounts or make fraudulent purchases. In 2024, synthetic identity fraud, which involves creating an identity from real and fake data, has become more sophisticated, often slipping past traditional verification measures.

Companies should consider cross-referencing identity information with verified databases or using KYC (Know Your Customer) solutions to validate new accounts.

4. Chargeback Fraud (Friendly Fraud)

Chargeback fraud, or friendly fraud, happens when a customer makes a legitimate purchase and then disputes the charge with their bank.

This type of fraud is challenging to combat, as the customer often knows the system and may exploit it to get refunds on items they have received. Businesses can protect against this by maintaining thorough transaction records, keeping evidence of order fulfillment, and implementing a clear return and refund policy.

5. Refund Fraud

Refund fraud has become a persistent issue, with fraudsters claiming a product never arrived or was damaged to obtain refunds. By implementing a requirement for return tracking numbers and inspecting returned goods carefully, businesses can reduce their susceptibility to refund fraud. Monitoring refund requests during high-activity time slot can also help identify suspicious patterns.

Step 2: Employ Advanced Customer Verification Techniques

• Use Two-Factor Authentication (2FA): 2FA is a highly effective method for verifying customer identity. By requiring a second authentication method, such as a code sent to the user’s device, businesses can prevent unauthorized access. For accounts with stored payment methods, 2FA is especially crucial as it adds an extra layer of security.
• Verify Customer Identity with Biometric Data: Incorporating biometric verification, like fingerprint or facial recognition, provides robust security and is increasingly accessible as mobile devices support these features. Although not universally adopted by ecommerce sites, adding biometric verification can significantly reduce instances of account takeover.
• Use Address Verification Service (AVS): AVS checks that the billing address entered matches the one on file with the credit card issuer, providing an added layer of confirmation before a purchase is completed. For high-risk transactions, consider adding additional verification steps, such as phone verification, to ensure accuracy.

Step 3: Invest in Fraud Detection Tools

• Real-Time Transaction Monitoring: Real-time transaction monitoring analyzes transaction patterns at the moment, identifying anomalies like rapid purchase attempts or purchases from geographically inconsistent locations. This approach allows fraud teams to flag or halt suspicious transactions, giving them a chance to verify legitimate purchases.
• AI and ML for Pattern Detection: AI and machine learning have transformed fraud detection by enabling systems to “learn” from past fraud patterns and adjust accordingly. By identifying unusual activity, such as a sudden surge in order volume from a specific IP address or repeat purchases using similar account information, these tools can alert fraud teams to potentially fraudulent activity.
• Device Fingerprinting: Device fingerprinting assigns a unique ID to each device accessing the website, making it possible to recognize repeat offenders. If a flagged device ID attempts a purchase or login, security systems can restrict access, helping prevent repeat fraud attempts from the same device.

Step 4: Implement Strong Payment Security Protocols

• Secure Payment Gateways: Using secure, PCI-compliant payment gateways is essential for protecting customer data. Payment gateways encrypt transaction data, ensuring that sensitive card information remains secure. Selecting reputable payment providers with anti-fraud features is essential to secure online transactions.
• Tokenization: Tokenization substitutes sensitive data with unique identifiers, or “tokens,” that are only meaningful to the payment processor. This strategy minimizes the storage of sensitive information on ecommerce sites, reducing the potential for data theft and ensuring customers’ data remains protected.
• Enforce PCI-DSS Compliance: PCI-DSS compliance is mandatory for ecommerce sites handling card payments. This set of security standards ensures the safe handling of credit card information, helping businesses implement secure data storage, access control, and regular system monitoring.

Step 5: Educate Your Customers and Team

• Customer Education on Fraud Prevention: Providing customers with resources on fraud detection, like identifying phishing emails and securing their accounts, can go a long way in minimizing fraud. Simple prompts, like advising users not to reuse passwords and enabling two-factor authentication, empower customers to protect their data.
• Employee Training on Fraud Detection: Employees are the first line of defense in many cases. Regular training sessions on identifying suspicious orders, responding to unusual activities, and handling sensitive data are crucial. Training employees to recognize social engineering tactics, such as phishing or pretexting, can also minimize insider threats.

Step 6: Monitor and Analyze Fraud Trends

• Regular Fraud Audits: Conduct fraud audits at least quarterly to review transaction histories and identify new fraud patterns. An audit may reveal overlooked vulnerabilities, like weak password policies or excessive permissions on customer accounts.
• Analyze Chargeback Patterns: Chargebacks offer valuable insights into potential fraud trends. Monitoring chargeback reasons and spotting patterns—such as disputes filed after a specific payment method—can guide policy adjustments and improve fraud response strategies.
• Leverage Data Analytics for Predictive Insights: Data analytics not only helps track historical data but also provides predictive insights into when and where fraud may occur. By leveraging this data, ecommerce sites can anticipate high-risk periods (e.g., holidays) and prepare accordingly with tighter fraud measures.

Step 7: Leverage Multi-Layered Security Measures

• Combine Multiple Security Layers: A single line of defense is rarely sufficient in 2024. Integrating several layers—like IP tracking, device fingerprinting, and 2FA—provides stronger protection by making it harder for fraudsters to breach security protocols.
• Use Geolocation and IP Tracking: By tracking a user’s location and IP address, ecommerce sites can detect unusual login behavior. For instance, if a user’s IP location changes suddenly, it may indicate account takeover attempts, enabling security teams to enforce stricter verification.
• Implement Velocity Checks: Velocity checks prevent repetitive actions within a short time, like multiple order placements or login attempts. This security measure helps detect bots and prevent automated fraud attempts, often seen during promotional periods or new product launches.

Step 8: Partner with Cybersecurity Experts

• Consult with Fraud Prevention Specialists:
  Fraud prevention specialists offer industry expertise, helping businesses identify specific vulnerabilities and implement customized solutions. By keeping abreast of new fraud techniques and regulatory changes, they ensure that security strategies remain current.
• Consider Managed Security Services:
  For businesses that lack the resources to manage in-house security teams, managed security services provide 24/7 fraud monitoring, incident response, and compliance management, all of which contribute to maintaining robust security postures.
• Stay Updated on Security Regulations:
  Staying informed about security regulations, such as GDPR for data privacy and PCI-DSS for payment security, ensures that businesses not only avoid fines but also maintain high standards of customer data protection.

Conclusion

With ecommerce fraud on the rise in 2024, the need for a proactive and multi-layered approach to security has never been greater. Implementing robust security protocols, leveraging fraud detection tools, educating customers and employees, and staying up-to-date with fraud trends are essential steps for ecommerce businesses to protect their assets and customer trust.
