Mobile commerce is a growing target, with fraudsters exploiting smartphones and apps through tactics such as card-not-present fraud and mobile phishing scams. Fake websites and increasingly sophisticated social engineering further expand the threat surface. Fraud occurs across various online transactions and platforms, highlighting the importance of secure online transactions to protect businesses and customers alike.
To stay ahead, businesses must adopt advanced e-commerce fraud prevention strategies. In this article, we will first provide a precise definition of e-commerce fraud, before reviewing its different types and corresponding risks. We will then present the 10 best practices for combating e-commerce fraud, followed by a deep dive into a highly effective solution, being CAPTCHAs.
What is E-Commerce Fraud?
E-commerce fraud refers to deceptive or unauthorized activities that target online businesses, customers, and digital systems for financial gain. Because the internet is border-less, fraudsters can operate globally, making detection, investigation, and prosecution more complex. As online shopping and payment technologies evolve, fraud tactics continue to grow more sophisticated.
Fraudsters constantly adapt their methods, making it harder for businesses to identify and stop fraudulent activity. This ongoing evolution underscores the importance of monitoring fraud trends, maintaining dedicated fraud teams, and using flexible e-commerce fraud prevention tools that can respond to emerging threats. Regularly updating and evaluating fraud prevention systems is essential to adapt to evolving fraud patterns and ensure effective protection across different markets.
E-commerce fraud detection plays a proactive role in protecting businesses and customers by identifying risks early and reducing financial losses. Payment processors and the credit card issuer are also critical in verifying transactions, using tools like address verification system (AVS) to check billing addresses, and resolving disputes such as charge-backs and fraudulent transactions.
Fraud detection solutions can include both in-house and third-party services, depending on the business size and needs. Ecommerce businesses must also stay informed about regulatory changes to ensure ongoing compliance and effective fraud management.
What Are the Types of Ecommerce Fraud ?
Below are the most common types of e-commerce fraud businesses face in 2026:
| Ecommerce Fraud Type | E-Commerce Fraud Risks |
|---|---|
|
Account Takeover Fraud (ATO) |
Uses real customer accounts and valid credentials, making fraudulent activity appear legitimate. Fraudsters may exploit legitimate customer accounts to make fraudulent purchases, often making these transactions appear authentic to merchants.
Read our How To Stop ATO article to dig deeper. |
|
Payment fraud no-card-present fraud, interception fraud, carding fraud. |
Direct financial losses, chargebacks, and increased processing fees. While controls like card verification value (CVV) and 3DS help, fraudsters constantly adapt to bypass them. Card-not-present fraud occurs when someone uses stolen payment information from data breaches to make unauthorized purchases online. Interception fraud involves placing orders using stolen payment information and then intercepting the package before it reaches its destination. Monitoring for multiple transactions in a short time frame can help detect suspicious activity. Carding attacks are a type of payment fraud: read our How To Prevent Carding Attacks guide to explore more. |
|
Gift Card Fraud |
Fraudsters hack or steal digital gift card numbers to commit gift card fraud, putting both businesses and customers at risk by enabling unauthorized use of gift card balances. |
|
Bot-Driven Attacks |
Bots operate at massive scale, overwhelming systems, distorting analytics, and enabling other fraud types like ATO and payment fraud – especially during peak sales events. Monitoring for multiple transactions in a short period is crucial to identify bot-driven fraud attempts. |
|
Friendly Fraud (Chargeback Fraud) |
Because financial transactions involve real customers and valid payments, it is difficult to distinguish online fraud from legitimate disputes. Excessive chargebacks can jeopardize merchant accounts. |
|
Synthetic Identity Fraud |
Fake identities and account creation fraud can pass verification and remain undetected for long periods, leading to accumulated losses that surface only after significant damage is done.
Identity fraud involves use of fake accounts – find out more in our fake account creation prevention guide. |
|
Phishing & Social Engineering |
Often acts as an entry point to other fraud types. Attacks target both customers and employees, exploiting human behavior rather than technical vulnerabilities. |
|
Policy abuse |
Occurs when customers exploit gaps in a merchant’s policies, such as abusing referral programs, discount codes, or creating multiple accounts to repeatedly use one-time offers. This can lead to significant revenue loss and undermine marketing efforts. |

Ecommerce fraud includes:
Account takeover (ATO): Attackers use stolen credentials to access real customer accounts and carry out seemingly legitimate transactions.
Payment fraud: Involves unauthorised transactions, card testing and chargebacks, resulting in direct financial losses and higher processing costs.
Bot-driven attacks: Use automated traffic on a large scale to enable other types of fraud, overwhelm systems and manipulate accounts, inventory or payments.
Friendly fraud, also known as chargeback fraud: Occurs when legitimate customers dispute valid transactions, making it difficult to detect and potentially endangering merchant accounts.
Synthetic identity fraud and phishing-based social engineering: Rely on fake or manipulated identities and human deception to bypass verification processes and gain long-term access to e-commerce platforms.
- Phishing and social engineering
- Policy abuses
A multi-layered strategy combining tools, policies and customer verification can support e-commerce fraud prevention. Standard technical checks such as CVV/CVN, address verification service, and IP risk scoring are essential.

E-commerce fraud is a specific type of cyber fraud. It is exclusively transactional in nature and only concerns transactions between a seller and a buyer. Examples of e-commerce fraud include account takeover (ATO) fraud, card-not-present fraud, and chargeback fraud. Cyber fraud, on the other hand, encompasses all types of digital fraud and scams. Examples of cyber fraud include phishing, ransomware, and romance fraud.
The best way to detect them is to closely monitor your bank statements. Unknown debits, unusual amounts or international transactions may be the first signs of fraud. Receiving unsolicited confirmation codes or requests for personal data by phone or email may also indicate attempted fraud.
