Merchant online fraud is a rampant deceptive activity that targets online businesses. ECommerce threats include scams like setting up fake storefronts, using stolen credit cards, account takeover, and identity theft.

This type of fraud can result in financial losses and reputational damage for the merchant, and customers may have their information compromised.

Types of merchant online fraud

Fake merchant storefronts: Fraudsters create fake online stores that look like legitimate businesses to steal customer payment information.

Credit and debit card fraud: Criminals use stolen credit card numbers to make purchases, often from fake online stores, to defraud credit card companies.

Account takeover (ATO): Scammers gain access to a customer’s existing account, using their credentials to make fraudulent purchases that can be difficult to detect because they appear to come from the legitimate account holder.

Phishing scams: Fraudulent emails or messages are sent to trick individuals into revealing sensitive information like login details or credit card numbers.

Identity theft: A fraudster obtains someone’s personal information (like name, address, and Social Security number) to make fraudulent purchases or open new accounts in their name.

Triangulation fraud: A fraudster sets up a fake online shop, takes a buyer’s payment, and then uses a stolen credit card to buy the same item from a real merchant, which is then shipped to the buyer. The fraudster pockets the original payment, while the legitimate merchant eventually faces a chargeback from the cardholder who disputes the charge.

Consequences for merchants

Financial loss: Merchants lose money from fraudulent transactions and are responsible for costs associated with chargebacks, which can include fees and penalties.

Reputational damage: If customers’ information is compromised or they are victims of a scam originating from the merchant’s site, it can damage the business’s reputation and erode customer trust.

Termination: A high chargeback ratio can lead to merchants being terminated from credit card networks, making it impossible for them to accept card payments.

How to protect against merchant online fraud

Monitor transactions: Look for unusual patterns, such as multiple transactions from the same IP address or different cards with the same billing address.

Use fraud detection tools: Implement systems that can identify and flag suspicious transactions before they are completed.

Follow best practices: Stay informed about the latest 2026 fraud trends and use methods to protect your business and customers.
