This article from our Blog will discuss the secret key to identifying and preventing e-commerce fraud in 8 easy steps. These strategies can ensure that your company is safe from fraud and that you remain proactive and alert.
This blog post will discuss:
- Common signs of eCommerce fraud
- Simple strategies for preventing fraud
Key Indicators of Suspicious Activities and Potential Fraud
For internet enterprises, e-commerce fraud may be expensive and harmful. To stop fraudulent activity and protect your income and reputation, you must recognize the warning indications.
Red flags that are frequently seen are using different cards from the same IP address, making unusually big purchases, shipping to strange or remote areas, having disparities between the IP and shipping addresses, and making a lot of transactions quickly.
Businesses may reduce risks and make the shopping experience safer for real customers by being aware of these indicators and putting appropriate fraud detection procedures in place.
1: Multiple Cards on the Same IP Address
One of the most significant warning signs of e-commerce fraud is the use of multiple credit cards from the same IP address. When legitimate customers shop online, they typically use a single card for their purchase or, at most, switch between a couple of cards.
However, when multiple cards are used from the same IP address within a short time frame, it can indicate fraudulent activity.
Fraudsters often employ a tactic known as “card testing,” where they attempt to use several stolen credit card numbers to determine which ones are active. They might make small purchases with these cards to avoid detection and then proceed with larger transactions once they confirm the validity of the cards.
In these scenarios, the IP address remains constant because the fraudster is often operating from a single computer or network. This activity is usually automated through the use of bots, which can test hundreds of cards in a matter of minutes.
Businesses can protect themselves by setting up alerts for unusual activity. For example, if more than three different cards are used from the same IP address in a short period, it could trigger an alert.
Implementing CAPTCHA on the checkout page can help deter automated bots. Additionally, cross-referencing the cards with databases of known stolen card numbers and using IP geolocation tools to identify high-risk locations can further reduce the likelihood of fraud.
In essence, while occasional use of multiple cards from the same IP address can occur in legitimate situations, such as in family households or small businesses, it’s often a sign of fraudulent activity. Continuous monitoring and prompt action are key to mitigating this risk.
2: Your Product Is Being Purchased in Large Quantities
Another warning sign of e-commerce fraud is when a product is being purchased in unusually large quantities. Typically, genuine customers buy in reasonable quantities depending on their needs.
A sudden spike in bulk purchases, especially of high-value items or easily resold products, could indicate fraud.
Fraudsters often target specific product categories, such as electronics, luxury items, or gift cards, as these can be quickly resold for cash. They may use stolen credit card information to buy large quantities of these products before the cardholder notices the unauthorized transaction and cancels the card.
The goal is to obtain as much merchandise as possible before the stolen card is reported, which can lead to significant losses for the merchant.
To identify suspicious bulk purchases, businesses should set thresholds for the number of units a single customer can buy.
For example, if a customer tries to purchase 50 units of a high-demand item when the average customer typically buys one or two, this should raise a red flag. Implementing purchase limits can deter fraudsters while still allowing genuine customers to shop normally.
Monitoring purchase patterns over time can also help identify trends that might suggest fraudulent activity. If certain products are frequently targeted for bulk purchases, consider implementing additional security measures, such as manual order reviews or two-factor authentication at checkout.
While genuine customers might occasionally make large purchases—such as during holiday seasons or for business purposes—consistently high-volume orders should be scrutinized, especially from new or unverified accounts.
3: Delivery to Odd Locations
Delivery to unusual or odd locations is a classic sign of e-commerce fraud. While customers may occasionally request delivery to a different address (e.g., sending a gift), deliveries to remote, uninhabited, or high-risk locations could indicate fraudulent activity.
Fraudsters often use drop locations to receive stolen goods without revealing their real identity. These addresses might be vacant properties, PO boxes, or even locations known for high levels of criminal activity. The purpose is to receive the goods without being traced, after which the items can be sold off quickly.
Businesses can combat this by implementing address verification systems (AVS) that compare the billing address provided with the one on file with the credit card company.
If there is a discrepancy or the delivery address is in a high-risk location, the system can flag the transaction for manual review. Additionally, requiring signature confirmation or photo identification upon delivery can help ensure the product reaches the correct recipient.
While legitimate customers may have valid reasons for unusual delivery addresses, such as sending items to a temporary work location or a friend’s house, it’s crucial to identify patterns.
For example, if a customer has a history of placing small, infrequent orders but suddenly requests a large shipment to a new location, this should warrant further investigation.
4: The IP Address Differs from the Shipping Address
A mismatch between the IP address and the shipping address is another warning sign of e-commerce fraud. When a customer places an order online, the IP address can reveal their geographical location.
If this location is significantly different from the shipping address—such as a customer ordering from one country but shipping to another—it could indicate fraudulent behavior.
Fraudsters often exploit this loophole by using VPNs or proxy servers to mask their actual IP address. They might appear to be in one location while shipping the product to another.
For example, an IP address based in Eastern Europe with a shipping address in the United States could suggest that the order is being placed by a fraudster outside the country. see How Can IP Addresses Be Traced for More Details.
Businesses should use IP geolocation tools to analyze where orders are coming from. If a discrepancy is detected, the order should be flagged for review. Setting up rules to automatically block or verify orders where the IP and shipping address don’t match can help mitigate this risk.
It’s important to note that there may be legitimate reasons for this mismatch, such as customers traveling or using VPNs for privacy reasons. However, repeated mismatches, especially when combined with other red flags like large orders or multiple cards, warrant closer scrutiny.
5: A Lot of Transactions in a Quick Amount of Time
Multiple transactions within a short period can indicate fraudulent activity, especially if the transactions are made from the same account or IP address.
Fraudsters often try to make as many purchases as possible before the stolen card information is reported and the card is deactivated.
To combat this, businesses can implement rate-limiting tools that restrict the number of transactions a single account or IP can perform within a set time frame. Setting transaction velocity limits—such as no more than five purchases in 10 minutes—can help deter fraudsters while still allowing legitimate customers to shop.
Monitoring transaction patterns is essential. Sudden bursts of activity, particularly on new or unverified accounts, should be flagged for further review. Additionally, using multi-factor authentication (MFA) and requiring additional verification for high-value transactions can add an extra layer of security.
While legitimate customers might occasionally make multiple purchases in a short time—such as adding items to their cart separately—consistent or high-value orders made rapidly suggest that it could be a fraud attempt.
Proven Strategies and Best Practices for Fraud Prevention
Businesses must prevent fraud to preserve customer trust and safeguard sensitive data. Important tactics include downloading fraud detection and management software, upgrading top-notch software, and evaluating and assessing fraud threats utilizing evaluation tools.
Protective measures such as mandating CVV numbers on all purchases, implementing PCI compliance, and implementing Risk-Based Authentication (RBA) improve security even further.
Transaction security is further guaranteed by the use of the Address Verification System (AVS) and HTTPS protocols.
To reduce vulnerabilities and identify suspicious activity in real-time, which lowers the likelihood of fraudulent behavior, regular audits, employee training, and updated cybersecurity standards are also essential.

4: The Role of PCI Compliance in Fraud Prevention
PCI compliance refers to the Payment Card Industry Data Security Standard (PCI-DSS), a set of security guidelines established to protect cardholder data and secure payment systems from breaches and fraud.
Businesses that handle, process, or transmit credit card information must comply with these standards to prevent data theft and ensure a secure environment for financial transactions.
Achieving and maintaining PCI compliance is crucial for reducing the risk of credit card fraud and protecting both business and customer information.
Understanding PCI Compliance Requirements
PCI-DSS consists of 12 primary requirements that address various aspects of data security, such as maintaining a secure network, implementing strong access control measures, and regularly monitoring and testing systems.
These requirements include measures like installing firewalls, encrypting stored data, restricting access to cardholder information, and maintaining secure authentication processes.
Compliance levels vary based on the volume of transactions a business processes annually, with higher transaction volumes requiring more stringent validation processes.
Essential Security Controls and Regular Assessments
To achieve PCI compliance, businesses must implement a variety of security controls. This includes configuring firewalls to protect internal networks, using encryption protocols to safeguard cardholder data, and installing anti-virus software to detect and prevent malware attacks.
Regular updates and patches should be applied to all software and systems to address vulnerabilities. Additionally, physical access to cardholder data must be restricted, and all personnel with access should undergo thorough background checks and training on PCI compliance practices.
Regular Vulnerability Assessments and Penetration Testing
PCI-DSS requires businesses to conduct regular vulnerability assessments and penetration testing to identify weaknesses in their systems.
Vulnerability assessments involve scanning systems for security flaws, while penetration testing simulates real-world attacks to test the effectiveness of security controls.
These tests help uncover potential vulnerabilities before they can be exploited by cybercriminals. Any issues identified during these tests must be addressed promptly to maintain compliance and protect sensitive data.
Maintaining Secure Access Control Measures
PCI compliance mandates strict access control measures to ensure that only authorized personnel can access cardholder data.
This includes implementing multi-factor authentication (MFA) for system access, creating unique IDs for each user, and restricting access based on job responsibilities. Role-based access control (RBAC) can be used to define user permissions, ensuring that employees have access only to the information necessary for their roles.
Monitoring access logs and maintaining detailed records of access attempts are also essential to track any unauthorized access attempts.
Continuous Monitoring and Logging
One of the key aspects of PCI compliance is continuous monitoring of network activities and logging of all access to cardholder data. This includes tracking system events, failed access attempts, and changes to security settings.
Detailed logs should be maintained for at least a year and be readily available for review.
Monitoring and logging provide a trail of evidence in the event of a security incident and enable businesses to detect and respond to suspicious activities in real-time.
Staying Up-to-Date with Compliance Requirements
The PCI-DSS is updated regularly to address emerging threats and evolving technologies. Businesses must stay informed about changes to the standard and ensure their compliance programs are updated accordingly.
Non-compliance can result in fines, increased transaction fees, and loss of the ability to process credit card payments. Regularly reviewing and updating compliance practices ensures that businesses remain secure and in line with industry standards.
By maintaining PCI compliance, businesses can demonstrate their commitment to security, protect sensitive cardholder information, and reduce the likelihood of experiencing a costly data breach or fraud incident.
5: Use RBA (Risk-Based Authentication)
Risk-Based Authentication (RBA) is a dynamic approach to security that adjusts the level of authentication required based on the perceived risk of a user’s login attempt or transaction.
RBA uses contextual information such as the user’s location, device, and behavior to evaluate the risk level and determine the appropriate authentication method.
This approach offers a more flexible and secure authentication process, reducing the likelihood of fraud while maintaining a seamless user experience.
How RBA Works and Its Benefits
RBA works by analyzing various factors during the authentication process to assess the risk associated with a particular action.
For example, if a user typically logs in from a specific device and location, an attempt from a different location or an unfamiliar device would be flagged as a higher risk.
Based on this assessment, the system can prompt for additional authentication methods, such as answering security questions, entering a one-time passcode (OTP), or using biometric verification. If the risk is deemed low, the user may be allowed to log in with just a password.
Key Benefits of Risk-Based Authentication
One of the primary benefits of RBA is its ability to provide enhanced security without inconveniencing legitimate users.
Traditional authentication methods, such as passwords and two-factor authentication (2FA), apply the same level of security to all users, regardless of the context. RBA, on the other hand, dynamically adjusts its security requirements based on the risk level.
This means that legitimate users can log in quickly and easily, while suspicious activities are subject to stricter verification processes.
Reducing Fraud and Account Takeovers
RBA is particularly effective at preventing account takeover (ATO) fraud, where cybercriminals gain unauthorized access to user accounts. By evaluating the risk of each login attempt, RBA can identify and block suspicious activities that might indicate a potential ATO.
For example, if a user’s credentials are compromised and an attacker attempts to log in from an unrecognized device, RBA can require additional verification or block the login altogether.
Contextual Factors Used in Risk-Based Authentication
RBA relies on several contextual factors to evaluate risk, including:
- Geolocation: The physical location of the login attempt. If a login is attempted from a country where the user has never been, it may be flagged as high risk.
- Device Fingerprinting: Identifies unique characteristics of the device being used, such as the browser type, operating system, and device ID.
- Login Time and Frequency: Unusual login times or multiple failed attempts in a short period can indicate a potential fraud attempt.
- IP Address Analysis: Recognizes trusted IP addresses and flags logins from unknown or suspicious IPs.
Implementing RBA in Business Systems
Businesses can implement RBA by integrating it into their existing authentication processes and security systems.
Many identities and access management (IAM) solutions now offer RBA as a feature, allowing businesses to configure custom risk policies based on their specific needs. The policies can be adjusted over time to respond to new threats and changes in user behavior.
Balancing Security and User Experience
One of the challenges of implementing RBA is balancing security with user experience.
Overly strict policies can lead to false positives, frustrating legitimate users, while lenient policies may leave gaps in security. Continuous tuning and monitoring of RBA settings are essential to ensure that it effectively prevents fraud without hindering legitimate activities.
Overall, RBA provides a robust and flexible approach to authentication that adapts to the risk level, making it an essential component of a comprehensive fraud prevention strategy.
6: Require CVV Numbers on All Purchases
Requiring the Card Verification Value (CVV) number for all online purchases is a simple yet effective method to prevent credit card fraud. The CVV number is a three or four-digit code found on the back of credit and debit cards, which provides an additional layer of security during transactions.
By making CVV entry mandatory, businesses can significantly reduce the risk of fraudulent transactions and enhance the security of online payments.
How CVV Numbers Help Prevent Fraud?
CVV numbers are designed to verify that the person making the transaction physically possesses the card. Since CVV codes are not stored in databases or printed on receipts, they cannot be easily accessed through data breaches or skimming devices.
This means that even if a cybercriminal obtains a customer’s credit card number and expiration date, they would still be unable to complete a transaction without the CVV. This added layer of security makes it more difficult for fraudsters to use stolen card information.
Compliance With Payment Security Standards
Many payment processors and credit card companies require businesses to collect CVV numbers to comply with security standards like PCI-DSS. Including CVV verification in the payment process demonstrates a commitment to data security and compliance.
Failing to adhere to these requirements can result in penalties, increased transaction fees, and loss of merchant account privileges. By enforcing CVV entry, businesses also show customers that they prioritize protecting sensitive financial information.
Reducing Chargebacks and Financial Losses
Chargebacks—when a customer disputes a transaction and the funds are returned to their account—are a common result of credit card fraud. Excessive chargebacks not only lead to financial losses but can also damage a business’s reputation and result in higher processing fees or even termination of the merchant account.
Requiring CVV numbers for all purchases helps reduce the likelihood of fraudulent transactions and subsequent chargebacks, thereby protecting the business’s financial health.
Enhancing Customer Trust and Confidence
Online shoppers are increasingly concerned about the security of their financial information. By implementing CVV verification, businesses can provide customers with an extra layer of security, enhancing trust and encouraging repeat purchases.
Displaying information about security practices, such as requiring CVV numbers, on checkout pages can reassure customers that their payment information is being handled securely.
Integrating CVV Verification Into Payment Systems
Integrating CVV verification into an existing payment system is relatively straightforward. Most e-commerce platforms and payment gateways support CVV entry by default.
Businesses can configure their systems to reject transactions that do not include a valid CVV number or prompt users to enter the code if it is missing.
It’s also possible to customize fraud filters to flag transactions where the CVV code does not match the card’s information on file.
Limitations of CVV Verification
While CVV verification is effective at preventing certain types of fraud, it is not foolproof. Cybercriminals can still obtain CVV codes through phishing attacks or by physically stealing the card.
Therefore, CVV verification should be used in conjunction with other security measures, such as multi-factor authentication (MFA), address verification, and monitoring for unusual transaction patterns.
By making CVV entry a mandatory step in the checkout process, businesses can enhance the security of online payments, reduce fraud, and build customer trust.
7: Implement HTTPS Protocol for Secure Transactions
Implementing HTTPS (Hypertext Transfer Protocol Secure) on your website is an essential measure to protect sensitive data, secure communications, and prevent fraud.
HTTPS encrypts the data transmitted between a user’s browser and the website, making it nearly impossible for unauthorized parties to intercept or alter the information.
Using HTTPS is especially important for e-commerce websites, financial services, and any site that collects personal information, as it safeguards user data and builds trust. See our Guide to Redirecting HTTP to HTTPS in WordPress for more details.
How & Why HTTPS is Critical for Fraud Prevention
HTTPS works by encrypting data using the Secure Socket Layer (SSL) or Transport Layer Security (TLS) protocols. When a user connects to a website with HTTPS, their browser and the web server establish a secure connection through an SSL/TLS handshake.
During this handshake, the server presents an SSL/TLS certificate, which contains a public key used to encrypt data. The browser uses this key to establish a secure session, ensuring that all data exchanged during the session is encrypted and protected from eavesdropping or tampering.
Why HTTPS is Important for Fraud Prevention?
- Data Encryption: HTTPS prevents data interception by encrypting all information transmitted between the user and the website. This means that even if cybercriminals manage to intercept the data, they cannot decipher or alter it without the encryption keys.
- Prevention of Man-in-the-Middle (MITM) Attacks: In an MITM attack, an attacker intercepts and potentially alters the communication between two parties without their knowledge. HTTPS prevents MITM attacks by ensuring that the data is encrypted and verified through SSL/TLS certificates.
- Secure Authentication: HTTPS ensures that users are connecting to the legitimate server of the intended website, preventing phishing attacks where a malicious site poses as a legitimate one. The SSL/TLS certificate helps verify the authenticity of the website, ensuring that users are not misled into entering their information on a fake site.
- Protection Against Content Injection: HTTPS prevents unauthorized third parties from injecting malicious code, advertisements, or malware into your website’s content. This type of attack can be used to defraud users by redirecting them to scam sites or stealing their credentials.
Benefits of Using HTTPS for Businesses and Customers
- Enhanced Customer Trust: When a website uses HTTPS, it displays a padlock icon in the browser’s address bar, indicating that the connection is secure. This visual indicator helps build trust with customers, making them more comfortable sharing personal and payment information on the site.
- SEO Benefits: Search engines like Google prioritize websites that use HTTPS in their rankings. Implementing HTTPS can improve search engine visibility, attract more visitors, and ultimately increase sales.
- Compliance with Regulations: Many data protection regulations, such as the General Data Protection Regulation (GDPR), require businesses to implement measures that protect the privacy and security of user data. Using HTTPS helps businesses comply with these regulations and avoid legal penalties.
Implementing HTTPS on Your Website
To implement HTTPS, businesses need to obtain an SSL/TLS certificate from a trusted Certificate Authority (CA). The certificate must be installed on the webserver to enable HTTPS.
Depending on the business’s needs, they can choose from different types of SSL/TLS certificates:
- Single Domain SSL Certificates: Secures one domain name.
- Wildcard SSL Certificates: Secures a domain and all its subdomains.
- Multi-Domain SSL Certificates: Secures multiple domain names.
After obtaining and installing the SSL/TLS certificate, businesses should configure their web server to redirect all HTTP traffic to HTTPS and regularly renew their certificates to maintain security.
Testing the site using tools like SSL Labs can help identify potential vulnerabilities and ensure that the implementation is secure.
Limitations and Additional Security Measures
While HTTPS significantly improves security, it is not a standalone solution. Businesses should implement additional security measures, such as secure coding practices, regular software updates, and vulnerability assessments, to further protect their sites from cyber threats.
Combining HTTPS with these measures provides a comprehensive approach to safeguarding data and preventing fraud.
8: Use AVS (Address Verification System)
The Address Verification System (AVS) is an anti-fraud tool that helps validate the authenticity of a credit card transaction by comparing the billing address provided by the customer with the address on file with the card issuer.
AVS is widely used by merchants to reduce the risk of fraudulent transactions and protect against chargebacks. Implementing AVS in payment systems provides an additional layer of security for both businesses and customers, ensuring that only authorized users can complete transactions.
How does AVS work?
When a customer makes a purchase using a credit card, they are asked to provide their billing address. AVS checks the numeric portions of the street address and the ZIP code against the information stored in the card issuer’s database.
The result of this comparison is returned as an AVS response code, which indicates whether the address provided matches the card issuer’s records.
Based on the response code, the merchant can decide to approve, decline, or review the transaction for further verification.
AVS Response Codes
AVS response codes typically indicate the level of match between the provided address and the card issuer’s records. Common AVS response codes include:
- Y (Yes): Address and ZIP code match.
- N (No): The address and ZIP code do not match.
- A (Partial Match): The address matches, but the ZIP code does not.
- Z (Partial Match): The ZIP code matches, but the address does not.
- R (Retry): System unavailable or timeout—merchant should retry the verification.
- U (Unavailable): Address information is not available for the card.
Merchants can use these codes to decide whether to accept, decline, or review a transaction.
For example, a full match (Y) is typically considered low risk, while a no match (N) might indicate potential fraud, prompting the merchant to decline the transaction or request additional verification.
Benefits of Using AVS
- Fraud Prevention: AVS helps prevent fraudulent transactions by verifying that the billing address provided by the customer matches the address on file with the card issuer. This reduces the risk of stolen card information being used to make unauthorized purchases.
- Reduction of Chargebacks: Chargebacks are often the result of fraudulent transactions. By using AVS, businesses can reduce the likelihood of accepting fraudulent transactions, thereby minimizing chargebacks and their associated fees and penalties.
- Enhanced Customer Security: Requiring address verification assures customers that the business is taking steps to protect their financial information, increasing trust and confidence in the company’s security practices.
Implementing AVS in Your Payment System
Most payment gateways and processors offer AVS as part of their fraud prevention toolkit. Businesses can enable AVS by configuring their payment systems to require address verification during the checkout process.
It’s important to ensure that the AVS settings are properly configured to handle different response codes and define rules for accepting or rejecting transactions based on the AVS results.
Limitations of AVS
While AVS is a valuable tool for verifying cardholder information, it has some limitations.
For example, AVS only checks the numeric portions of the address, which means that variations in how the address is formatted can result in mismatches. Additionally, AVS does not cover all international transactions, as some countries do not support address verification.
Combining AVS With Other Security Measures
Businesses should use AVS in conjunction with other anti-fraud methods including fraud detection software, Risk-Based Authentication (RBA), and CVV verification to optimize security.
With its multiple layers of protection, this method guarantees that only valid transactions are handled while guarding against all forms of fraud.
Businesses can increase customer satisfaction, lower the risk of financial loss, and safeguard themselves against fraud by implementing AVS in conjunction with other security procedures.

Regularly updating systems and educating staff and customers about fraud prevention also play crucial roles.
4: How do fraud detection tools work in e-commerce?
Fraud detection tools for e-commerce work by analyzing a variety of data points, such as purchase history, user behavior, IP addresses, and device information, to flag suspicious transactions.
These tools often use a combination of rules-based algorithms and machine learning models that learn from historical data to identify fraudulent patterns. When a potentially fraudulent transaction is detected, the system may automatically decline the transaction, request additional verification, or flag it for manual review by a fraud specialist.
5: What role does customer education play in preventing e-commerce fraud?
Customer education is crucial in preventing e-commerce fraud because informed customers are less likely to fall victim to scams. Educating customers on best practices, such as creating strong passwords, recognizing phishing emails, and reporting suspicious account activity, helps reduce the risk of account takeovers and identity theft.
E-commerce businesses should provide educational resources, send alerts about possible threats, and guide customers through setting up security features like two-factor authentication.
6: How can I develop a comprehensive fraud prevention strategy for my e-commerce business?
Developing a comprehensive fraud prevention strategy requires a balanced approach that includes technology, policies, and education. Start by implementing robust fraud detection tools and security measures like encryption, tokenization, and two-factor authentication.
Create clear policies for handling disputes and chargebacks, and establish a protocol for reviewing suspicious transactions. Regularly update and review these policies to keep up with evolving threats.
Finally, train your team to recognize fraud patterns and educate your customers about safe online shopping practices. This holistic approach will help mitigate fraud risks and build trust with your customers.
