Ecommerce Fraud Protection: The Ultimate Guide to Securing Your Online Store in 2024
Ecommerce is booming, with global sales expected to reach $6.3 trillion by 2024, according to Statista. However, this rapid growth has come with a dark side — a parallel surge in online retail fraud.
As an ecommerce merchant, protecting your business and customers from the ever-evolving threat of fraud is critical. Scammers are becoming smarter, attacks are increasing in frequency and sophistication, and the costs are staggering.
The True Cost of Ecommerce Fraud
How much is fraud really costing online retailers? Let‘s look at some eye-opening statistics:
- Online merchants lost an estimated $20 billion to payment fraud in 2021, an 18% jump YoY (Juniper Research)
- The average retailer has a 1.6% chargeback rate on transactions (LexisNexis)
- Every $1 in fraud costs companies $3.36 due to chargebacks, fees, lost products, etc. (LexisNexis)
- False declines, when legitimate transactions are flagged as fraud, cost merchants $331 billion in 2020 (Aite Group)
- One-third of customers who experience a false decline never shop with that merchant again (Riskified)
In other words, the costs of fraud go far beyond just the value of stolen goods or lost sales. Fraud can lead to crippling chargebacks, sky-high fees, customer churn, and severe brand damage. No ecommerce business can afford to ignore these risks.
Common Types of Ecommerce Fraud
To effectively combat ecommerce fraud, you first need to understand how scammers are exploiting online stores. Here‘s a breakdown of the most prevalent fraud tactics:
Card Testing
In this scheme, fraudsters make small purchases on a website using stolen card numbers to test if they are still active, before maxing them out elsewhere. Card testing bots can test thousands of card numbers in minutes.
Example: In 2016, hackers stole over 320,000 credit card numbers from Tesco bank and used them to make thousands of small purchases to verify the numbers before selling them.
Chargeback Fraud
Also called "friendly fraud", this is when a customer makes a purchase then requests a chargeback from their bank claiming the product wasn‘t delivered or they didn‘t make the purchase. The merchant loses both the product and the money.
Example: A customer buys a laptop from your store, then calls their bank and says it never arrived. The bank refunds their money, and you‘re left paying for the chargeback fee and the lost laptop.
Account Takeover (ATO)
In an ATO attack, a scammer gains access to a customer‘s account, then changes the password and makes unauthorized purchases. They may also steal saved payment methods or personal info.
Example: Using a stolen password, a fraudster logs into a customer account on an electronics website, changes the email and password, then uses the stored credit card to buy several smartphones.
Triangulation Fraud
In triangulation fraud, the scammer sets up a fake online store and sells popular products at deep discounts. When a customer makes a purchase with their credit card on the fake site, the scammer then uses that card to buy the product from a real retailer and ships it to the customer. The scammer pockets the difference.
Example: A scam website sells new iPads for just $100. Customers jump at the deal and make purchases. The scammer uses their cards to buy iPads from Apple.com for $500 each and ships to the customers, netting $400 per sale.
Interception Fraud
In this scam, the fraudster makes a purchase on your site with stolen payment details and has it shipped to the victim‘s address. Then they contact your company, claim they provided the wrong shipping address, and ask you to reship the order to a new address. You end up sending the product twice, and the actual cardholder disputes the purchase, leaving you on the hook.
Example: A scammer uses a stolen card to buy a designer handbag on your site and ships it to the card owner‘s address. Then they contact your service team, claim it was a gift and they put the wrong address, and convince you to reship it to them. The victim then disputes the charge, and you lose the bag plus pay a chargeback fee.
These are just a few of the many tactics fraudsters are using to target ecommerce stores. With scammers constantly developing new techniques and becoming more sophisticated, staying one step ahead is an ongoing challenge.
12 Ecommerce Fraud Prevention Best Practices for 2024
Now that you know the enemy, let‘s dive into specific, actionable steps you can take to prevent fraud and protect your ecommerce business:
-
Require CVV for All Card Transactions
The Card Verification Value (CVV) is the 3-4 digit code printed on credit cards. Always require customers to provide the CVV at checkout, as it helps verify they have the physical card. Scammers often only have stolen card numbers, not the CVV. -
Use an Address Verification System (AVS)
An AVS compares the numeric parts of the billing address provided by the customer to the address on file with the card issuer. While it‘s not foolproof, AVS is an important layer of fraud prevention you should have enabled. -
Set Limits on Purchase Frequency and Value
Consider setting daily, weekly, or monthly limits on the number and dollar value of purchases a single account or card can make. This helps limit your exposure if a scammer takes over an account or tests dozens of stolen cards. -
Require Strong Customer Passwords
Weak or reused passwords make it easy for hackers to break into customer accounts. Set minimum password strength requirements like length, complexity, and uniqueness. Avoid allowing easy-to-guess passwords like "password123". -
Use Fraud Detection Tools
Fraud detection software uses algorithms and machine learning to analyze transactions in real-time and flag ones that seem high risk. Some tools let you automate what happens to flagged orders, like requiring manual review or cancellation. Top solutions include:
-
Implement 3D Secure for Added Protection
3D Secure adds an extra authentication step for online card payments. It asks the customer to complete an additional verification with the card issuer, like entering a code sent to their phone, to prove they are the real cardholder. This can stop scammers who only have card numbers. -
Require Security Codes for Digital Gift Cards
Digital gift cards are a top target for scammers, who often steal the numbers and resell them online. Require a unique security code to redeem digital gift cards, and only show a partial card number in the customer‘s account. -
Be Wary of Suspicious Orders
Train your staff to watch for red flags like:
- Larger than normal orders
- Many small orders in a short period
- Multiple orders to the same address with different cards
- Billing and shipping address mismatch
- Abnormal shipping requests like overnight delivery for a low-value order
- Sequence of declined transactions before a successful one
- Orders from countries you typically don‘t sell to
Manually review orders with multiple red flags before fulfilling them.
-
Get Expert Help
If you don‘t have in-house fraud prevention expertise, consider hiring ecommerce fraud consultants to help assess your weaknesses, create a comprehensive strategy, and implement the right systems and processes. Look for experts certified by the Association of Certified Fraud Examiners (ACFE). -
Monitor Chargebacks Carefully
Keep a close eye on your chargeback rate, as a spike is a major red flag. Map chargeback reason codes back to specific transactions and look for patterns that may signal weak points in your fraud defenses. Fight chargebacks you believe are cases of friendly fraud. -
Create a Formal Fraud Prevention Policy
Work with IT, finance, and other stakeholders to create a documented fraud prevention strategy detailing:
- Your company‘s risk tolerance
- Required customer authentication methods
- Fraud tools and systems to be used
- Ongoing employee training requirements
- Acceptable chargeback rate
- How to handle suspicious orders
- Process for investigating confirmed fraud
Regularly review and update the policy to keep up with evolving fraud trends.
- Educate & Engage Customers
Consider your customers partners in fraud prevention. Educate them on protecting their accounts, like using strong passwords and being wary of phishing emails. Let them know about your fraud prevention efforts and why you sometimes need additional verification. Most customers will appreciate that you‘re serious about security.
