The Rising Threat of Omnichannel Fraud for Ecommerce Store Owners: Is Your Business at Risk?

Online sales keep growing, and so does the risk of omnichannel fraud, fraud that spans multiple channels and touchpoints instead of hitting just one. If you run an online business, strong fraud prevention practices are no longer optional; fraudsters are exploiting the same channel-switching that makes shopping convenient for real customers.

This guide covers how omnichannel fraud works, the five most common types merchants run into, why it is rising, and the concrete steps that reduce it, including how changing technologies and consumer shopping trends have created new openings for fraudsters to exploit.

What is Omnichannel Fraud?

This fraud is a type of financial crime that takes place across multiple communication channels. These include digital and physical channels such as the internet, phone banking, credit, and debit cards along with new technologies like ATMs and AI-based payment apps. 

The prevalence of such fraud can be attributed to advances in technology giving fraudsters new ways to exploit systems while simultaneously making it harder for law enforcement and other organizations to detect and block fraudulent chargebacks. 

In order to reduce this growing threat, organizations must adopt more advanced defenses that utilize predictive analytics and machine learning tools along with an omnichannel approach that allows for monitoring across all possible channels. By combining intelligent solutions such as these with end-user education, secured protocols, and continuous risk assessment, businesses can better protect themselves from Omnichannel Fraud.

How Does It Differ From Traditional Fraud?

Omnichannel fraud differs from traditional fraud methods in its complexity and blend of different access channels. It consists of malicious activities that occur on digital channels, such as websites or mobile apps, as well as physical channels like stores, customer service centers, and call centers. 

While the majority of traditional fraud activity happens on a single access channel, such as unauthorized credit card usage, this type of fraud involves multiple access channels at once. 

Furthermore, it often has multiple points of contact, with criminals targeting consumers across multiple touchpoints to get all the information they need to commit fraud. 

manual high-risk order screening may not be enough when attempting to detect and prevent omnichannel fraud, as it requires an advanced approach that incorporates data analysis and control mechanisms across all access channels and is focused on customer behavior.

Omnichannel Fraud Statistics for Merchants

Based on the latest data from TransUnion's H1 2026 Top Fraud Trends Report:

• 8.3% of digital account creation attempts were suspected of fraud in 2025, the highest-risk stage in the customer lifecycle. This is driven by the growth in digital transactions, more sophisticated fraud tooling, and easier access to stolen data.
• Fraudsters are targeting a variety of industries, but travel & leisure, logistics, and financial services are seeing the highest increases in fraud attempts. This is because these industries are experiencing significant transaction volume increases, as the pandemic has driven shifts in consumer behavior.
• Account takeover is the fastest-growing method, with the suspected account takeover fraud rate up 37% from 2024 to 2025. It involves using stolen credentials to access a victim's account. Credit card cloning creates a counterfeit card using the victim's account information, and synthetic identity fraud combines real and fake information to obtain credit or other financial products.
• Merchants can take a number of steps to reduce their risk of fraud, including implementing strong fraud prevention measures, educating their employees about fraud, and working with a fraud prevention partner. Strong fraud prevention measures include using tools such as fraud scoring, device fingerprinting, and transaction monitoring. Educating employees about fraud can help them identify and report suspicious activity. Working with a fraud prevention partner can provide merchants with access to the latest fraud prevention technology and expertise.

Types of Omnichannel Fraud

As businesses increasingly rely on omnichannel strategies to reach and engage customers, they face new challenges in preventing fraud. Omnichannel fraud refers to fraudulent activity that occurs across multiple channels, such as online, mobile, and in-store, which is difficult to detect and prevent because of how varied and interconnected those channels are.

Here are some of the most common types of omnichannel fraud:

1. Account Takeover (ATO) Fraud

ATO fraud occurs when a fraudster gains unauthorized access to a customer's account, such as a bank account, e-commerce account, or social media account. This can be done through various methods, such as phishing, social engineering, or brute force attacks. Once the fraudster has access to the account, they can steal personal information, make fraudulent purchases, or transfer funds to their own account.

2. Synthetic Identity Fraud

Synthetic identity fraud is a type of fraud where a fraudster creates a new identity by combining real and fake information. The fraudster may use stolen personal information, such as social security numbers, to create a synthetic identity and open new accounts or apply for loans. This type of fraud can be particularly challenging to detect as the synthetic identity may appear legitimate on the surface.

3. Payment Fraud

Payment fraud refers to fraudulent activities involving payment methods and payment service providers, such as credit cards, debit cards, and digital wallets. Payment fraud can occur in various ways, such as through stolen card information, fraudulent chargebacks, or account takeovers. Payment fraud can also occur through online marketplaces where fraudsters may sell fake products or use stolen credit cards to purchase items.

4. Loyalty Fraud

Loyalty fraud occurs when a fraudster takes advantage of a loyalty program by earning rewards or benefits through fraudulent means. For example, a fraudster may use stolen points or create multiple accounts to earn more rewards. This type of fraud can be difficult to detect as it may involve small transactions spread out over a long period.

5. Phishing and Social Engineering

Phishing and social engineering refer to methods used by fraudsters to trick individuals into revealing personal information, such as passwords or credit card information. Phishing typically involves sending fraudulent emails or messages that appear to be from a legitimate source, such as a bank or e-commerce site. Social engineering involves manipulating individuals into divulging information through phone calls or in-person interactions.

Types of Omnichannel Fraud at a Glance

Why is Omnichannel Fraud on the Rise?

Omnichannel fraud is a growing issue, which is driven by a combination of factors. According to the latest data from CyberSource, global e-commerce grew by almost 21% in 2020 and the top 20 world economies saw a 50% increase in e-commerce fraud activity during this same time period. 

Additionally, the COVID-19 pandemic forced shoppers to find alternative ways to purchase items, resulting in exponential growth in cross-channel activity for retailers. The resulting difficulty for online retailers who need to manage hundreds of accounts across multiple touchpoints has made it increasingly difficult to detect fraud activities as they happen. 

This difficulty in detection has led to an overall increase in these fraud attempts over recent years, and many experts predict fraud levels will keep rising as reliance on e-commerce grows worldwide.

How Does Omnichannel Fraud Affect Businesses?

Fraudsters use sophisticated techniques to exploit vulnerabilities in these channels, resulting in various negative impacts on businesses. Here are some ways in which omnichannel fraud affects businesses:

1. Financial Losses from Fraud

The most obvious impact of omnichannel fraud on businesses is financial loss. Fraudsters use stolen or fake identities to make fraudulent purchases or transfer money from a victim's account to their own. This can result in chargebacks, refunds, and loss of revenue for the business. In addition, businesses may also face fines and penalties from payment processors and regulatory authorities for failing to prevent fraud.

2. Damage to Brand Reputation and Customer Trust

It can also damage a business's reputation and erode customer trust. If customers experience fraud or unauthorized transactions on their accounts, they may lose faith in the business and switch to competitors. Negative reviews and feedback on social media and review sites can further damage the business's reputation and discourage potential customers from doing business with them.

3. Legal and Regulatory Risks

Businesses that fail to prevent or detect fraud may face legal and regulatory risks. They may be liable for damages resulting from fraudulent transactions and may be required to comply with data protection regulations and consumer protection laws. Non-compliance can result in fines, lawsuits, and other legal penalties.

4. Operational Costs

Businesses may incur additional operational costs to prevent and mitigate fraud. This may include investing in fraud detection and prevention tools, hiring fraud analysts, and training employees to identify and report suspicious activity. These costs can add up quickly and reduce the business's profitability.

Protecting Your Business from Omnichannel Fraud

As a business owner, it’s essential to have foolproof safety protocols in place to protect yourself, customers, and employees from fraud. Having the right prevention strategies can help your business stay ahead of any potential problems. 

Just like with creating any effective privacy policy, being proactive about protecting your business from omnichannel fraud can be the difference between success and failure. When creating these strategies, there are a few best practices to keep in mind such as using two-factor authentication for logins and transaction monitoring for when payments are made. 

Additionally, it's important to consider how you will respond if suspect fraud does occur - developing processes that quickly detect and address any suspicious activity is key. Technology can also provide reliable assistance when it comes to preventing fraud - using digital identification verification services like facial recognition or AI-based monitoring tools can significantly decrease your exposure to risk and increase customer trust in your brand.

There are many factors at play when it comes to protecting yourself from online fraudulent activities but with the right strategies in place you can create a secure environment for customers, employees and yourself alike.

Frequently Asked Questions About Omnichannel Fraud

How do I prevent fraud across online, mobile app, and in-store channels?

Use tools that share fraud signals across every channel instead of monitoring each one separately, device fingerprinting, transaction monitoring, and two-factor authentication all work best when they draw on the same customer data no matter which channel a transaction came through. Pair that with employee training and a fraud prevention partner who already correlates that data for you.

What is the difference between omnichannel fraud and cross-channel fraud?

The terms are often used interchangeably. Both describe fraud that spans more than one channel, online, mobile, and in-store, rather than staying confined to a single access point, which is what makes it harder to catch than traditional single-channel fraud.

What is the best omnichannel fraud prevention strategy?

The strongest strategies combine predictive analytics and machine learning with monitoring that spans every channel at once, not just the digital ones. Two-factor authentication, transaction monitoring, and identity verification tools reduce risk further, and reviewing the strategy regularly matters as much as the tools themselves, since fraud tactics keep shifting.

Is omnichannel fraud a bigger risk for B2B or B2C merchants?

Both face it, but the entry points differ. B2C merchants see more account takeover and payment fraud tied to individual consumer accounts, while B2B merchants face more synthetic identity fraud tied to new account and credit applications. Either way, the same cross-channel monitoring approach applies.

What is account takeover fraud and how does it fit into omnichannel fraud?

Account takeover happens when a fraudster gains unauthorized access to an existing account, often through phishing, social engineering, or credential stuffing, and it is the fastest-growing omnichannel fraud type, up 37% year over year as of 2025. It fits into the bigger omnichannel picture because a single compromised login can be exploited across web, mobile, and in-store channels alike.

Turn Omnichannel Fraud Into Recovered Revenue, Not Lost Revenue

Omnichannel fraud is only going to get harder to catch as more of it moves across channels at once. Businesses need a chargeback prevention strategy that reviews and updates itself as fraud tactics change, not a static checklist.

Chargeflow is a fully automated chargeback management solution built to catch the disputes that slip through, whatever channel they started on. It uses AI to gather evidence and submit responses automatically, so fraud that does get through does not have to mean lost revenue.

Here is what that gets you:

• Save time: Chargeflow automates the response process across every channel, so your team is not building evidence packets by hand for every dispute.
• Higher win rate: AI-built responses are tailored to the reason code behind each dispute, whether it started online, on mobile, or in-store.
• Lower costs: fewer lost disputes and less manual work mean lower overhead, backed by Chargeflow's own recovery data.
• Fewer repeat disputes: Chargeflow surfaces the patterns behind your chargeback ratio, so you can close the gap the fraud came through, not just refund the loss.

If fraud is slipping across channels faster than your team can catch it, see how Chargeflow closes the gap automatically.
