Ecommerce fraud isn’t only a nuisance – it’s a profit killer. Chargebacks, stolen identities, and phishing scams drain revenue, damage reputations, and force businesses into high-risk merchant categories. But here’s the truth: most fraud prevention guides recycle the same generic advice.
This isn’t one of them.
In this blog post, we’ll cover the fraud types plaguing online businesses, expose their red flags, and provide actionable detection strategies that go beyond basic payment gateways.
According to a study conducted by Statista, in 2024, online payment fraud losses were estimated at $44 billion. Just five years later, it is forecasted to surpass the whopping $100 billion mark by 2029.
Understanding Fraud Types in Ecommerce
We’ve covered the fraud types in commerce in this section below:
1. Payment Fraud
What Happens:
Credit card details are stolen or generated illegally to make purchases. Criminals often test card validity with small transactions before larger thefts.
Warning Signals:
- Multiple payment attempts with slight variations in card numbers
- Rush shipping requests on high-value orders from new accounts
- Billing and shipping addresses that don’t match
Example:
A fraudulent buyer purchases five smartphones in one hour using different cards, all shipped to the same warehouse address.
2. Account Takeover
What Happens:
Fraudsters gain access to legitimate customer accounts using stolen credentials, often from data breaches.
Warning Signals:
- Sudden changes to account details (email, shipping address)
- Unusual login locations or devices
- High-value orders from previously inactive accounts
Example:
A long-time customer’s account is compromised, and $2,000 worth of gift cards are purchased and sent to an unrecognized email.
3. Chargeback Fraud
What Happens:
Customers falsely dispute charges, claiming they never received items or didn’t authorize the purchase.
Warning Signals:
- Disputes filed immediately after delivery confirmation
- Repeat offenders using the same payment method
- High-ticket items commonly disputed
Example:
A buyer claims a $1,200 laptop was “never delivered” despite tracking showing a signed receipt.
4. Refund and Returns Abuse
What Happens:
Customers exploit return policies by sending back used, damaged, or counterfeit items.
Warning Signals:
- Frequent returns from the same customer
- Items returned in clearly used condition
- “Missing item” claims on sealed packages
Example:
A shopper buys a designer dress, wears it once, and returns it with tags reattached.
5. Synthetic Identity Fraud
What Happens:
Fraudsters combine real and fake information to create new identities for fraudulent purchases.
Warning Signals:
- Minimal or no credit history
- Recently created email addresses and phone numbers
- Social media profiles that don’t match provided details
Example:
A “customer” uses a fabricated identity with a real Social Security number (SSN) to open multiple accounts and max out credit lines.
6. Triangulation Fraud
What Happens:
Scammers use a legitimate store as a middleman to fulfill orders placed with stolen cards elsewhere.
Warning Signals:
- Orders shipped to freight forwarders or shippers
- Buyers who refuse contact after purchase
- High demand for expedited shipping
Example:
A fraudulent eBay seller lists a PlayStation 5, uses a stolen card to buy it from your store, and ships it to the eBay buyer.
7. Promo and Coupon Abuse
What Happens:
Fraudsters exploit discounts by creating fake accounts or sharing codes illegally.
Warning Signals:
- Multiple accounts using the same promo code
- Bulk purchases of discounted items
- Codes shared on coupon forums
Example:
A single user redeems a “first-purchase” discount 50 times using different email addresses.
8. Affiliate and Ad Fraud
What Happens:
Fraudulent publishers generate fake clicks or sign-ups to collect commissions.
Warning Signals:
- High click-through rates with zero conversions
- Traffic from suspicious geolocations
- Sudden spikes in low-quality referrals
Example:
An affiliate uses bots to simulate clicks on ads, draining your ad budget without real sales.
9. Phishing and Brand Impersonation
What Happens:
Scammers impersonate your brand to steal customer data or payments.
Warning Signals:
- Fake customer support accounts on social media
- Lookalike domains tricking users into logging in
- Emails requesting sensitive information
Example:
Customers receive emails pretending to be your billing department, asking for card updates.
10. Carding
What Happens:
Criminals test batches of stolen credit cards to verify which ones work.
Warning Signals:
- Multiple small-dollar transactions in quick succession
- Cards from different issuers used in the same session
- Failed authorization attempts followed by a successful charge
Example:
A fraudster tests 100 stolen cards with $1 donations to a charity page.
11. Application Fraud
What Happens:
Fake profiles are created to exploit sign-up bonuses or bypass purchase limits.
Warning Signals:
- Profile photos sourced from stock images
- Disposable email addresses
- No linked social media accounts
Example:
A scammer opens 20 accounts to abuse a “new customer” free shipping offer.
12. Refund and Returns Abuse (Expanded)
What Happens:
Organized groups systematically exploit return policies for profit.
Warning Signals:
- Similar return patterns across multiple accounts
- Claims of “empty box” deliveries on high-value items
- Returns shipped from the same location under different names
Example:
A fraud ring buys electronics, removes components, and returns them as “defective.”
7 Red Flags to Detect Ecommerce Fraud
Fraudsters leave clues – if you know where to look. Below are the seven most critical red flags professional fraud investigators use to spot scams in real time. When these red flags start hovering around, this tells you that something fishy is going on in your store.
These are some of the common red flags to keep in mind:
1. Mismatched Billing & Shipping Addresses
Why It’s Suspicious:
Legitimate customers rarely ship to addresses unrelated to their billing details. Fraudsters often:
- Use stolen credit cards with the real owner’s billing address
- Ship to freight forwarders or “drop addresses” to hide their location
How to Detect:
- Flag orders where the shipping city/country doesn’t match the card’s issuing bank
- Block high-risk locations (e.g., known reshipping hubs in Delaware or Miami)
2. Rush Shipping on High-Value Orders
Why It’s Suspicious:
Fraudsters want goods before the cardholder notices unauthorized charges. They’ll often:
- Pay extra for overnight shipping on luxury items or electronics
- Use guest checkout to avoid account verification
How to Detect:
- Review all expedited shipping requests for new customers
- Require step-up verification (e.g., short message service (SMS) or email confirmation) for rush orders
3. Multiple Payment Declines Before Success
Why It’s Suspicious:
This signals card testing – fraudsters brute-force stolen cards to find working ones.
How to Detect:
- Block IPs with >3 declined transactions in 10 minutes
- Deploy CAPTCHA or 3D Secure after the first decline
4. New Accounts with Unusual Purchase Patterns
Why It’s Suspicious:
Legitimate shoppers rarely:
- Create an account and immediately buy $1,000+ of goods
- Purchase items with no logical connection (e.g., 10 pairs of the same shoes)
How to Detect:
- Set velocity rules (e.g., “max $500 spend for first-time buyers”)
- Require ID verification for high-risk categories (e.g., gift cards, electronics)
5. Requests to Ship to Remote or High-Fraud Areas
Why It’s Suspicious:
Certain locations are fraud hotspots:
- Lithuania, Nigeria, or Indonesia for international fraud
- Newark, NJ, or Miami, FL, for domestic reshipping scams
How to Detect:
- Geo-block transactions from high-risk regions
- Manually review orders shipping to remote warehouses
6. Disposable Emails & Fake Social Profiles
Why It’s Suspicious:
Fraudsters use:
- Temporary email services (e.g., GuerrillaMail, Mailinator)
- Social media profiles with no friends, posts, or profile photos
How to Detect:
- Block domains from known disposable email providers
- Cross-check social media accounts (e.g., LinkedIn, Facebook) for legitimacy
7. Identical Devices Across Multiple Accounts
Why It’s Suspicious:
Fraudsters reuse the same:
- Device fingerprint (e.g., same browser/operating system (OS) combo)
- Internet protocol (IP) address even with virtual private networks (VPNs, some metadata leaks)
How to Detect:
- Use device fingerprinting tools (e.g., FingerprintJS, SEON)
- Flag users with >3 accounts linked to one device
What Is a High-Risk Business?
In the financial services industry, a high-risk business describes businesses that pose a higher level of risk to financial institutions due to the nature of their operations. This risk can be associated with a variety of factors, including the industry in which the business operates, its financial stability, its history of chargebacks or digital fraud, the legality of its products or services in different jurisdictions, and more.
High-risk businesses often face challenges such as:
- Higher processing fees from payment processors
- Not eligible for convention payment processing
- Monthly transaction limits
- Stricter contract terms
- Difficulties in securing loans or other forms of financing
- May be subject to more frequent financial audits and regulatory scrutiny
- More substantive Know-Your-Customer (KYC) procedures
Ecommerce fraud can play a significant role in your status as a high-risk business. You may operate in a high-risk industry, like an online pharmacy, which may get you labeled as a high-risk business. However, if your business has a history of fraud, finding a payment processor may be more difficult to find.
Top Factors Affecting Your Business Risk Status
There are numerous factors that can get you labeled as a high-risk online business. Some of these factors are out of your control – for example, the industry you operate in. But there are factors like your online identification process that you can change.
These are some indicators of high-risk businesses:
1. Your Industry
Whether you are classified as a high-risk merchant or low-risk merchant may depend on your sector or if your website must check age to sell alcohol or other age-restricted products online. There are greater risks in some businesses than others.
The following are just a few of these industries:
- Cigarette
- Drugstores
- Electronics
- Financial services
- Gambling
- Gaming
- Legal services
- Pharmacy
- Travel and hospitality
2. Online Fraud Vulnerabilities
Online fraud is a possibility if your ecommerce business lacks a high security infrastructure. Working with ecommerce merchants at risk of rising online fraud events is something that many merchant service providers are reluctant to do.
3. Chargeback History
You will be held responsible for the losses if chargebacks are made. Acquiring banks may classify you as a high-risk merchant if your ecommerce business has a history of receiving many chargebacks. Due to the possibility of fraud, you must determine the source of these chargebacks. It can also indicate that you need to improve your customer service.
4. Years in Business
The age of your ecommerce company may also affect your reputation as a high-risk merchant. It is clear that new companies in the sector could have to establish themselves before getting the best status designations and rates from merchant service providers.
5. Volume of Transactions
Your company faces a greater financial risk if it conducts hundreds or thousands of transactions every day through its online store. This increases the likelihood that criminals may attempt to steal data and credit card details.
6. Lengthy Delivery Times
Long delivery periods may lead to mistakes. On the road, anything might go wrong and harm your products. This increases the likelihood that your company may suffer losses. Your ecommerce business consequently becomes a risk for the merchant service provider.

Here’s the kicker: 75% of ecommerce businesses planned to increase their fraud prevention budget within the next 12 months, according to a 2023 Ravelin study.
Fraud Monitoring Processes for Ecommerce
Any type of fraud requires a thorough monitoring process. For an ecommerce store, we’ve compiled that process here for you:
1. Manual Detection vs. Automatic Detection
| Method | Relies on human review, intuition, checklists, and visual inspection. | Utilizes AI/Machine Learning (ML) algorithms, rule-based systems, and pattern recognition. |
| Speed & Efficiency | Slow and time-consuming; limited by human processing speed and availability. | Instantaneous and highly efficient; operates at machine speed, 24/7. |
| Accuracy & Consistency | Prone to human error, fatigue, and inconsistency; results can vary. | High accuracy and consistency; continuously learns and adapts from data. |
| Scalability | Difficult to scale; requires hiring and training more personnel as volume increases. | Highly scalable; handles vast and increasing data volumes effortlessly. |
| Cost | High ongoing labor costs; significant operational expense per transaction. | Higher initial setup investment; significantly lower operational cost per transaction. |
| Fraud Adaptation | Reacts to known patterns; slower to adapt to novel or evolving fraud schemes. | Proactively identifies new, complex, and emerging fraud patterns in real-time. |
| Bias | Susceptible to human bias and subjective judgment. | Reduces human bias; relies on objective data and algorithmic rules. |
| Data Handling | Limited to manageable data sets; struggles with large, complex volumes. | Excels with massive, diverse, and complex datasets in real-time. |
2. Full-Stack Fraud System
A full-stack fraud system offers end-to-end protection across every stage of a transaction. It is a dynamic, multi-layered defense that is constantly monitoring and adapting to new threats.
Key characteristics include:
- Holistic Data Integration: Unifying identity, transaction history, device data, and external intelligence for complete risk assessment.
- Multi-Layered Detection: Employing AI/ML algorithms, rule-based engines, and behavioral analytics for robust defense.
- Real-time Decisioning: Instantly approving, denying, or reviewing transactions, minimizing friction for legitimate customers.
- Adaptive Learning: Continuously evolving to detect emerging fraud tactics without manual intervention.
- Automated Action: Orchestrating immediate responses like blocking transactions or flagging suspicious activity across various systems.
3. Generic Payment Tools Are a Big No
Generic payment tools, while convenient for basic transactions, often lack the specialized capabilities needed to combat sophisticated fraud and manage risk effectively as your ecommerce business grows.
Their limitations become clear as your business expands:
- Basic Fraud Checks: They offer only simple verifications, inadequate for detecting complex, evolving fraud patterns.
- Slow Adaptation: Without self-learning capabilities, they can’t keep pace with new fraud schemes, leaving you vulnerable.
- Fragmented Data View: They operate in silos, failing to integrate vital identity, transaction, and device data for holistic risk assessment.
- Manual Review Overload: Limited automation leads to a surge in false positives and manual reviews as volume increases, creating unsustainable operational burdens.
Best Practices: Your Proactive Ecommerce Fraud Prevention Checklist
When you want to protect your ecommerce business, you need to follow multiple approaches. And to do that, you must have a checklist ready with you:
1. Adhere to Strong Authentication Protocols
It’s time to say goodbye to generic passwords.
- Multi-Factor Authentication (MFA): Require users to verify their identity through at least two different methods (e.g., password + code to phone) for logins and high-value transactions.
- Tiered Trust Scores: Assign dynamic risk scores to users and transactions based on their history, behavior, and various data points. This allows for adaptive authentication, requesting more verification for higher-risk activities.
- Device Fingerprinting: Identify and track unique device attributes to flag suspicious logins or transactions coming from unfamiliar or spoofed devices.
- UX-Optimized Verification: Ensure verification steps are seamless and unintrusive for legitimate customers, balancing security with a smooth user experience.
2. Keep Your Software Up to Date
Outdated software has “welcome” written on the door for fraudsters. Regular updates patch vulnerabilities that could otherwise be exploited. This includes your ecommerce platform, plugins, payment gateways, and any third-party integrations.
3. Use Advanced Fraud Detection Systems
Steer clear of basic checks with intelligent systems designed to identify complex fraud patterns.
- Address Validation: Verify customer shipping and billing addresses against reliable databases to prevent fraud stemming from incorrect or manipulated address information.
- Card Testing Blockers: Implement systems that detect and stop automated attempts by fraudsters to test stolen credit card numbers against your payment gateway.
4. Integrate Secure Payment Processing Gateways
Your payment gateway is a critical control point. Ensure it offers advanced fraud prevention features.
SSL Certificates + Secure Gateways
- SSL Certificates: An active SSL (Secure Sockets Layer) certificate encrypts data transmitted between your customers’ browsers and your server, protecting sensitive information like credit card details. Look for “https://” in your URL.
- Secure Gateways: Utilize payment gateways that are PCI DSS compliant and employ their own robust security measures to protect transaction data during processing.
Why Finance-Only Tools Aren’t Enough
While your payment processor and traditional financial tools are essential for handling transactions, they are fundamentally designed for financial processing, not comprehensive fraud prevention. Relying solely on them leaves significant gaps in your defense.
For businesses dealing with higher transaction volumes, specific industries, or a history of chargebacks, this inadequacy can be critical. This is where a high-risk Merchant Account can step in.
1. High-Risk Merchant Account: Saving Your Business
For certain industries (like vape shops, CBD, or subscription services) or businesses with a history of chargebacks, a “high-risk” designation is often unavoidable. However, it’s not a scarlet letter, but rather a recognition of increased exposure, often leading to higher fees. Critically, these accounts also often come bundled with or require more stringent fraud prevention measures.
2. High-Risk Merchant Account Benefits
While seemingly a challenge, these accounts can offer benefits in fraud prevention by:
- Access to Specialized Tools: High-risk processors often integrate or mandate advanced fraud detection systems, offering more robust protection than standard accounts.
- Greater Scrutiny: The very nature of a high-risk account means more vigilant monitoring and stricter protocols are in place, which, while sometimes inconvenient, acts as a stronger deterrent to fraudsters.
- Reduced Chargebacks (Ultimately): By employing stronger fraud tools and processes, the long-term goal is to reduce your chargeback rate, which directly impacts your bottom line and reputation.
Fraud Monitoring Processes for Ecommerce
Effective ecommerce fraud prevention is an ongoing, active process of monitoring. Modern fraud monitoring goes far beyond simple transaction checks, employing sophisticated techniques to stay ahead of malicious actors.
What Modern Monitoring Includes
Modern monitoring provides a dynamic, real-time view of potential threats:
- Behavioral Monitoring: Analyzing user interactions, such as typing speed, mouse movements, time spent on pages, unusual navigation paths, or rapid successive purchases, to identify bot activity or human imposters.
- Device Fingerprinting: Continuously tracking and analyzing unique attributes of devices (e.g., operating system, browser version, IP address, installed fonts) to spot anomalies like multiple accounts from one device or a single account logging in from multiple, suspicious devices.
- Geographical Monitoring: Detecting unusual or illogical geographic patterns, such as a login from one country immediately followed by a purchase attempt from another, or transactions originating from known high-risk regions.
Why Manual Methods Fall Short
Relying on manual review processes for fraud detection in ecommerce is unsustainable and inefficient for several reasons:
- Scale: Human teams simply cannot process the sheer volume of transactions and data generated by a growing ecommerce business in real-time.
- Speed: Manual reviews introduce significant delays, impacting customer experience and potentially leading to false declines.
- Complexity: Modern fraud is intricate. Human reviewers struggle to identify subtle patterns across vast datasets that advanced algorithms can easily spot.
- Cost & Error: Manual review is expensive (staffing) and prone to human error, leading to missed fraud or frustrating false positives.
These limitations make manual methods a bottleneck, highlighting the urgent transition to advanced verification technology.
