Ecommerce Fraud Prevention: 19 Practices for All Fraud Types

Understanding ecommerce fraud

Ecommerce fraud hurts businesses and shoppers. It takes many forms and can lead to financial losses and damaged trust.

Defining ecommerce fraud

Ecommerce fraud happens when someone tries to cheat or steal during online shopping. This can include using stolen credit cards, lying about not getting orders, or deceiving people into sharing private info.

Fraudsters may pretend to be real customers to make fake purchases. They might hack accounts to buy things without permission. Some create fake websites that look like real stores to steal money and data.

How ecommerce fraud impacts businesses

Ecommerce fraud causes big problems for online stores. It leads to lost money from fake sales and chargebacks. Stores often have to pay fees when fraud happens.

Fraud can also hurt a store’s reputation. Customers may not trust the store if their info gets stolen. This can make people less likely to shop there.

Dealing with fraud takes time and resources. Stores need special tools and staff to spot and stop it. This costs money that could be used for other things.

Fraud can also mess up inventory. Fake orders might make stores run out of items for real customers. This can lead to unhappy shoppers and lost sales.

8 ecommerce fraud types

In this section, we’ll look into 8 ecommerce fraud types, explaining how each one works and how you can protect your business from them.

Friendly fraud

Friendly fraud happens when a customer asks their bank for a chargeback on a valid purchase. This type of fraud can be tough for online stores to handle. Customers might claim they never got their item or that it was damaged. Sometimes they forget they made the purchase or don’t recognize the charge on their bill.

You might wonder why it’s called “friendly” fraud. The name comes from the idea that the customer isn’t always trying to be dishonest. They might just be confused. But for online stores, the results are the same as other types of fraud.

When friendly fraud happens, you lose the product and the money from the sale. You also have to pay chargeback fees. This can add up fast and hurt your bottom line. To protect yourself, keep good records of all sales and shipments. Make sure your store name shows up clearly on credit card bills. Reach out to customers before they file a dispute if you can.

Account takeover

Account takeover is a type of ecommerce fraud where someone gets into a customer’s online account without permission. This can happen on shopping websites, banking apps, or other online services.

Fraudsters often use various mechanisms to steal login information. They might send fake emails or set up phony WiFi networks to capture passwords. Sometimes they buy stolen account details on the dark web.

Once they’re in, they can do a lot of damage. They might make purchases, change account settings, or steal personal info. This can hurt both the customer and the business.

To protect yourself, use strong passwords and two-factor authentication. Be careful about clicking links in emails or texts. Watch your accounts for strange activity.

Businesses can fight this fraud by using good security systems. They should check for unusual login patterns or purchases. Training staff to spot red flags is also important.

Triangulation fraud

Triangulation fraud is an online shopping scam. It involves three parties: a scammer, an unsuspecting buyer, and a real business. The scammer sets up a fake online store with low prices to lure buyers.

When you make a purchase on the fake site, the scammer uses stolen credit card info to buy the item from a real store. They ship it to you and pocket your money. You get the product, but it’s bought with a stolen card.

This fraud is hard to spot. The fake store looks real, and you actually receive your order. Signs of triangulation fraud include very low prices and unfamiliar websites. Be careful when shopping online and stick to trusted stores.

To protect yourself, check store reviews and look for secure payment options. If a deal seems too good to be true, it might be a scam. Always use caution when shopping on new or unknown websites.

Clean fraud

Clean fraud is a serious ecommerce scam. Fraudsters use stolen credit card info to make purchases that look real. They have all the right details, like billing addresses and security codes. This makes it hard for stores to spot the fraud.

You might wonder how clean fraud works. Criminals get valid card data from data breaches or the dark web. They then use this info to make purchases that seem normal. The transactions pass security checks because all the details match up.

Clean fraud is tough to catch. It looks just like a real purchase from the actual cardholder. Stores may not know it’s fraud until the real owner reports unauthorized charges. By then, the scammer has already gotten away with the goods.

To fight clean fraud, you need smart detection systems. Look for unusual patterns in orders. Be wary of mismatches between shipping and billing addresses. Use extra verification for high-value purchases. These steps can help protect your business from clean fraud losses.

Interception fraud

Interception fraud is a scheme, through which criminals try to get between you and your customers. They aim to grab products before they reach the real buyer.

Here’s how it works: A fraudster places an order using stolen payment info. Then they contact you, pretending to be the customer. They ask you to change the shipping address. If you do, the package goes to the scammer instead of the real buyer.

This fraud can hurt your business in several ways. You lose the product and shipping costs. The real cardholder may request a chargeback. Your reputation can also take a hit if customers don’t get their orders.

You can protect yourself by having strict rules for address changes. Always verify requests through secure channels. Be wary of last-minute changes, especially for high-value items.

Refund fraud

Refund fraud is a big problem for online stores. It happens when people try to get money back for items they bought, but they’re not being honest.

There are different ways people do this. Some buy things, use them once, and then return them. This is called “wardrobing” or “free renting.” They treat the store like a free rental service.

Others make fake receipts to get refunds for things they never bought. Some switch price tags to get more money back than they should.

Employees can also be part of refund fraud. They might work with friends to process fake returns.

This type of fraud costs stores a lot of money. It’s not just a small issue – it adds up to billions of dollars each year. That’s why stores need to be careful and have good return policies.

Identity theft

Identity theft is when thieves steal personal info to make fake accounts or buy things. They might take names, addresses, and credit card numbers.

Thieves can use this info to order stuff without paying. They may also open new accounts in your name. This hurts both shoppers and stores.

Stores lose money when fraudsters use stolen cards. Customers face a mess fixing their credit. It can take time to sort out which charges are real.

You can protect yourself by using strong passwords. Don’t give out personal info unless you’re sure it’s safe. Check your bank statements often for weird charges.

Stores can help by using good security. They should check orders carefully. Using systems to spot odd buying patterns helps too.

Card testing

Card testing is a type of fraud where criminals use stolen credit card info to make small purchases. They do this to check if the card works before making bigger purchases. It’s a big problem for online stores.

Fraudsters often use automated tools to test many cards quickly. They might buy cheap items or make tiny donations. These small charges can slip by unnoticed.

For shoppers, card testing can mean surprise charges on your account. Keep an eye on your statements for odd, small purchases. Report anything suspicious to your bank right away.

Online stores can protect themselves by using fraud detection tools. These tools look for patterns that might show card testing. Stores can also set limits on how many purchases a customer can make in a short time.

You can help stop card testing too. Use strong passwords and don’t share your card info online. If you notice weird charges, tell your bank fast.

19 ecommerce fraud prevention practices

This section covers 19 key ecommerce fraud prevention strategies, including essential measures like AVS and CVV checks as well as advanced techniques such as machine learning and biometric authentication. Implementing these practices helps secure your online business, protect customer data, and reduce the risk of fraudulent activities.

Implement address verification service (AVS)

Address Verification Service (AVS) helps prevent fraud in online transactions. It checks if the billing address a customer enters matches the one on file with their credit card company.

AVS compares the numeric parts of the address and ZIP code. If they match, it’s more likely the transaction is legitimate. This extra check makes it harder for fraudsters to use stolen card info.

You can set up AVS through your payment processor. When a customer makes a purchase, AVS runs automatically. You’ll get a response code showing how well the addresses match.

Based on the AVS results, you can decide whether to approve, review, or decline a transaction. This gives you more control over potential fraud risks.

Remember, AVS isn’t perfect. Some legitimate transactions may not pass. That’s why it’s good to use AVS along with other fraud prevention methods.

Use card verification value (CVV)

CVV is a security code on credit and debit cards. It’s usually 3 or 4 digits long. You can find it on the back of most cards.

When customers shop online, you should ask for their CVV. This helps prove they have the real card. Fraudsters often don’t have this code, even if they stole other card details.

Requiring CVV can cut down on fraud a lot. It’s a simple step that makes a big difference. Many payment systems let you turn on CVV checks easily.

Remember, CVV is just one part of fraud prevention. Use it with other methods for the best protection. Always follow payment rules about how to handle CVV data.

Detect fraud on customer behavior analysis

AI-powered systems can spot odd customer actions. These systems learn normal buying habits. They flag unusual activity that might be fraud.

One key sign is sudden changes in spending. A customer who usually buys small items then makes a big purchase could raise a red flag. The system checks if this fits their normal pattern.

Another clue is strange login times or places. If someone always shops from New York but suddenly logs in from Russia, that’s suspicious. The AI notes this and may ask for extra proof it’s really them.

Buying speed matters too. Most people take time to browse and choose items. If someone adds lots of expensive things to their cart very fast, it might not be the real customer.

By watching these behaviors, online stores can catch fraud attempts early. This helps protect both the business and real customers from losses.

Enable two-factor authentication

Two-factor authentication adds an extra layer of security to your online accounts. It requires users to provide two different forms of identification when logging in. This makes it much harder for hackers to access your accounts, even if they know your password.

Many ecommerce platforms now offer two-factor authentication. To set it up, you’ll typically need to enter your phone number or email address. You’ll then receive a unique code each time you try to log in.

Using two-factor authentication is like having two locks on your door. Even if someone gets past the first lock, they still can’t get in without the second key. This extra step can go a long way in keeping your account safe from fraud.

You should turn on two-factor authentication for all your important online accounts, especially those related to your ecommerce business. It’s a simple but powerful way to protect yourself from cyber threats.

Use proxy piercing technique

Proxy piercing helps detect fraudsters hiding behind proxy servers. It reveals the true IP address of users, which can indicate potential fraud risks. Some online shoppers use proxies for privacy, but fraudsters often use them to mask their location.

You can use proxy piercing in a few ways. One method is session monitoring. This tracks user behavior during their visit to your site. Another approach analyzes the IP address to check if it’s coming from a proxy server.

If proxy piercing detects a proxy, you can take action. You might flag the order for review or block the IP address. But be careful not to reject all proxy users. Some legitimate customers use proxies too.

Proxy piercing works best as part of a larger fraud prevention strategy. It’s not perfect on its own, but it can help you spot red flags. When combined with other tools, it can boost your defenses against online fraud.

Conduct regular security penetration tests

Security penetration tests are key for ecommerce sites. These tests help find weak spots in your website’s defenses. You should run them often to stay safe from hackers.

Pen tests mimic real attacks on your site. They show where criminals might break in. This lets you fix problems before they cause harm.

You can hire experts to do these tests. They use special tools to check your site thoroughly. They look at things like login pages, payment systems, and data storage.

After the test, you’ll get a report. It will list any issues found and how to fix them. Make sure to address these problems quickly.

Regular testing helps keep your site secure over time. As you add new features, more weak spots can appear. Frequent checks catch these before they become big issues.

Implement device fingerprinting

Device fingerprinting is a powerful tool for ecommerce fraud prevention. It looks at unique details of a user’s device to spot suspicious activity. This can include things like the operating system, browser type, and screen resolution.

To implement device fingerprinting, you need to add code to your website that collects this information. Many fraud prevention services offer plugins or APIs to make this easier. Once set up, it runs in the background each time someone visits your site.

The system creates a “fingerprint” for each device. It then compares this to known patterns of fraud. If something looks off, you can take action. This might mean blocking a transaction or asking for more verification.

Device fingerprinting helps catch fraud that other methods might miss. It can spot when someone is using a stolen credit card on a new device. It also helps identify bots or automated attacks.

Add ReCAPTCHA for bots protection

ReCAPTCHA is a great tool to protect your ecommerce site from bots and fraud. It checks if a user is human or a bot. You can add it to your login, registration, and checkout pages.

To set up ReCAPTCHA, you need to get a key from Google. Install the ReCAPTCHA JavaScript on your site’s frontend. This lets you collect data on bot activity.

Put the ReCAPTCHA check on key user actions. For example, when someone tries to log in or make a purchase. This helps stop bots from making fake accounts or orders.

ReCAPTCHA v3 is the latest version. It gives a score for each user action. You can use this score to decide if an action seems risky. Low scores may mean it’s a bot.

Remember, ReCAPTCHA should be part of a larger fraud prevention plan. Use it with other tools to keep your site safe.

Leverage machine learning algorithms for fraud detection

Machine learning helps catch online fraud. These smart computer programs look at lots of data to spot weird patterns. They can find insights that humans might miss.

You can use machine learning to check if a purchase looks real. It looks at things like what someone usually buys and where they shop from. If something seems off, it can flag the order for a closer look.

These tools keep getting better at finding fraud. They learn from past data to catch new scams. This helps keep your online store safe without slowing down good customers.

Some big payment companies use machine learning already. It helps them keep fraud rates low – like less than 30 cents lost for every $100 processed. That’s pretty good for online sales.

As more people shop online, machine learning becomes even more useful. It can handle lots of orders at once and adapt to new fraud types fast.

Utilize risk scoring systems

Risk scoring systems help you spot shady transactions. These tools use AI to check many factors like purchase history, user behavior, and location. They give each transaction a risk score.

High scores mean more danger. You can set up rules to flag or block risky orders. This saves time and cuts losses from fraud.

Some systems let you tweak settings. You can adjust how strict the scoring is. This helps balance fraud prevention with good customer experience.

Risk scoring works best as part of a bigger plan. Use it with other methods like address verification. This gives you better protection against fraud.

Remember that no system is perfect. Keep an eye on your scores and adjust as needed. This helps catch new types of fraud.

Set up strict password policies

Strong passwords are key to protecting online stores from fraud. You should require customers to create complex passwords when making accounts. A good policy asks for at least 8 characters with a mix of uppercase and lowercase letters, numbers, and symbols.

Don’t allow common words or phrases as passwords. Block passwords that have been leaked in data breaches. Set up your site to reject weak password choices automatically.

Make customers change their passwords regularly, like every 3-6 months. This helps keep accounts secure even if old passwords get exposed. You can send email reminders when it’s time for a password update.

Enable multi-factor authentication as an extra safeguard. This asks users for a second form of proof, like a code texted to their phone, before letting them log in. It stops hackers who might guess or steal a password.

Train your staff on good password habits too. They should use strong, unique passwords for all work accounts. Consider using a password manager to help everyone create and remember complex passwords safely.

Employ biometric authentication

Biometric authentication adds a strong layer of security to your online store. This method uses unique physical traits like fingerprints or facial features to verify customers. It’s harder for fraudsters to fake these than passwords.

You can add biometric checks to your login process. This makes it tougher for foreign actors to access accounts. Many smartphones now have built-in fingerprint or face scanners. You can use these for quick, secure logins.

Voice recognition is another option. Customers can speak a phrase to prove who they are. This works

Limit transaction sizes and velocities

Setting transaction limits helps protect your online store from fraud. You can cap the maximum amount a customer can spend in one purchase. This stops criminals from making huge orders with stolen cards.

You can also set velocity limits. These restrict how many transactions a customer can make in a set time period. For example, you might allow only 5 purchases per hour from one account.

These limits let normal shoppers buy freely while blocking suspicious activity. You can adjust them based on your typical order sizes and customer behavior.

Some payment systems let you create custom rules. You might set different limits for new customers versus longtime buyers. Or have stricter controls for high-risk products.

Monitoring transactions in real-time helps catch issues fast. Set up alerts for unusual patterns like many small purchases or orders from far-flung locations.

Ensure PCI DSS compliance

PCI DSS is a set of rules for businesses that handle credit card data. You need to follow these rules to protect your customers’ payment information.

To comply with PCI DSS, you should encrypt all card data. Use strong firewalls and anti-virus software to guard your systems. Limit access to sensitive data and keep track of who views it.

Regular security checks are important. Test your systems often to find weak spots. Fix any issues quickly to stay secure.

Train your staff on PCI DSS rules. They should know how to handle card data safely. This helps prevent mistakes that could lead to data breaches.

Keep your software up to date. Old systems can have security flaws that hackers can exploit. Regular updates fix these problems and keep your data safe.

Work with secure payment processors. They can help you meet PCI DSS standards. This makes it easier to protect your customers’ information.

Enable multi-currency support while monitoring fraud

Multi-currency support is key for online stores selling worldwide. It lets customers pay in their own currency. This can boost sales and trust. But it also brings new fraud risks.

To handle this, use a payment system that checks transactions in different currencies. Look for odd patterns or high-risk countries. Set up rules for each currency based on typical spending.

Train your fraud team on currency-specific issues. They should know exchange rates and common scams in various regions. Use tools that convert all transactions to a base currency for easier comparison.

Keep an eye on currency fluctuations. Sudden changes can mask fraud attempts. Update your fraud rules regularly to match current exchange rates and trends.

Remember, offering multiple currencies is great for growth. But it needs extra care to keep your store safe from fraud.

Consider tokenization for storing credit card data

Tokenization can help protect your customers’ credit card information. This method replaces card numbers with unique tokens. These tokens are random strings that can’t be traced back to the original card data.

When a customer makes a purchase, their card info is sent to a token service provider. The provider creates a token and sends it back to you. You can then store this token safely instead of the actual card number.

Tokenization makes your data less valuable to hackers. Even if someone breaks into your system, they won’t find any real card numbers. This can reduce your risk of data breaches and fraud.

Using tokenization can also improve your customers’ experience. They won’t need to enter their card info every time they shop with you. This can lead to more repeat business and customer loyalty.

Many payment processors offer tokenization services. Look for one that fits your business needs and budget. Make sure they follow PCI DSS rules for handling card data.

Offer secure mobile payment options

Mobile payments are becoming more popular for online shopping. You can make your store safer by adding secure mobile payment choices. These options use special tech to protect customer data.

Digital wallets like Apple Pay and Google Pay are good picks. They use encryption to keep payment info safe. This makes it harder for criminals to steal customer data.

Biometrics can also boost security. This means using things like fingerprints or face scans to check who’s paying. It’s a strong way to make sure the right person is making a purchase.

When you pick mobile payment options, look for ones with built-in fraud detection. Some can spot weird buying patterns that might mean fraud. This helps catch problems before they cause trouble.

Advanced fraud prevention techniques

Online stores need cutting-edge tools to stay ahead of scammers. These methods use smart tech and data analysis to spot fraud fast.

Machine learning and AI

Machine learning and AI help catch fraud attempts. These tools look at lots of data to find odd patterns. They get smarter over time as they see more examples.

AI can check orders super fast. It spots things humans might miss. For example, it can flag an order if the shipping address is far from where the card is usually used.

Some AI tools can even predict future fraud attempts. They learn from past scams to guess what might happen next. This helps stores stop fraud before it starts.

Behavioral analytics

Behavioral analytics tracks how users act on a website. It can spot when something seems off about an order.

This method looks at things like:

• How fast someone types
• If they copy and paste info
• What pages they visit
• How long they spend on each page

If someone acts different from normal customers, it might be a red flag.

Stores can set up rules based on common fraud behaviors. For example, if someone makes many orders with different cards in a short time, the system can block them.

These tools help catch fraud without bugging real customers. They work in the background to keep stores safe.

Conclusion 

Ecommerce fraud is a big problem for both businesses and customers. As online shopping gets more popular, fraudsters find new ways to scam. Learning about the different types of ecommerce fraud helps you protect your business and customers. By using fraud prevention methods—from simple steps like AVS and CVV checks to advanced tools like machine learning—you can greatly lower the risk of fraud.
