What is Email Account Takeover Fraud?

by Theresa Nguyen 5 min read June 25, 2024

With more consumers online, bad actors are taking the opportunity to commit more financial crimes, such as account takeover fraud. This online scheme resulted in nearly $13 billion in losses in 2023, up from $11 billion in 2022.1 So, what do organizations need to know about this form of identity theft? And how can they prevent it?

Let’s explore one type of account takeover fraud: email account takeover.

What is email account takeover?

Email account takeover occurs when a fraudster gains access to a legitimate user’s email account through data breaches that expose credentials, purchasing from the dark web, or phishing scams. It’s usually one of the first steps in a broader account takeover scheme.

Once fraudsters have access to a consumer’s email or social media account, they have access to the private information in that consumer’s inbox: financial statements, health records, and other forms of PII. Fraudsters can also now use the consumer’s email to impersonate them with friends, family, financial institutions or other businesses they interact with.  

They can also gain access to other accounts and here’s where email account takeover becomes more dangerous. In this attack, the fraudster gains access to an email or mobile account. Once they have an email, they start by trying to guess the user’s password, commonly called a brute force attack, or through password spraying, where they use commonly used passwords, i.e. ‘password’ or ‘123123.  A recent Google survey found that 65% of people use the same password for some or all of their online accounts. This, along with a corresponding email address can give fraudsters further entre into a consumer’s other accounts. If unsuccessful, they’ll then execute a ‘forgot password’, password reset, or one–time password. Then, they take over the victim’s account with their financial institution to facilitate the transfer of funds from the compromised account.

  • 57% of businesses are experiencing rising fraud losses associated with account opening and account takeover.2

While email account takeover can be quickly executed, detecting it can take time. Unlike credit card fraud, where an individual may soon notice suspicious activity, an email account takeover can go undetected for longer. The owner may not realize until later that their account has been compromised, especially with a dormant account or secondary account they use less. As a result, criminals have more time to facilitate additional attacks.

How does it affect your organization?

Account takeover fraud doesn’t just impact consumers, it can result in significant financial losses for organizations. For example, if your organization offers credit products, you might have to cover the costs of disputing chargebacks, card processing fees, or providing refunds. In the case of a data breach, you may have to pay fines against your organization for not properly protecting consumer information.

  • Nearly two-thirds of consumers say they’re very or somewhat concerned with online security.3

But email account takeover isn’t just costly — it can damage your organization’s reputation. Consumers expect organizations to have proper security measures in place to protect their information. If a data breach occurs, your security can seem weak, leading consumers to lose trust in your organization. As a result, they may potentially take their business elsewhere.

The importance of prevention

While consumers listed identity theft as their top concern when conducting activities online, they’re still interacting, opening new accounts, and transacting digitally.4 Coupled with the rise of account takeover fraud and associated losses, it’s more crucial than ever for organizations to accurately detect and prevent these attacks. To do this, they must have a proactive fraud prevention strategy in place.

Account takeover fraud prevention requires your business to maintain and continuously reaffirm confidence in the identity data you collect. Your team can monitor, segment, and proactively act on customer identities that display a higher risk of fraud than was determined at account origination through risk-based fraud detection models, machine learning, and advanced analytics.

Experian offers many flexible solutions, including:

  • CrossCore® Solutions are best practice-based groupings of fraud and identity products that enable organizations to solve common to complex issues. For example, our fraud risk solutions include email and phone intelligence to improve verification for thin-files and other challenging populations. Experian offers phone/carrier–based matching capabilities with address validity and occupancy data for >95% of U.S. households.
  • FraudNet is a device intelligence solution that analyzes hundreds of device attributes and prevents fraud on all digital channels. Combining contextual data, behavioral data, and device data, it bridges the gap between physical and digital identity to achieve fraud capture rates that exceed industry averages.

To further alleviate account takeover fraud, your organization can offer educational resources for fraud prevention. Using various, strong passwords across their accounts, and changing them regularly, is a foundational way consumers can help ensure their accounts are secure. Leveraging user names that are different from your email can also help. If a fraudster is able to takeover an account and initiate a lost password request, and that password is used for other accounts, that fraudster now has the credentials they need to further defraud that consumer. By spreading awareness about identity fraud risks and providing best practices for prevention, you can better protect your organization and consumers.

One Platform, Fewer Handoffs, Faster Decisions

The average credit union manages between 100-300 vendor relationships, and nearly a third have no dedicated staff managing them. What was supposed to drive efficiency is stunting growth and compromising the member experience. Application volume is continuing to rise, and consumers expect a loan decision at digital speed. But for credit unions, meeting that expectation isn't the only goal. They must also continue to make the right lending decisions while also prioritizing risk management. The institutions pulling ahead aren't the ones with the most tools. They're the ones that have turned credit, fraud and decisioning into a single, coordinated system. A single loan decision touches: Credit data Identity verification Fraud signals Decisioning logic Reporting Rarely does all of that live in one place. More often, it’s stitched together across separate platforms, each with its own contract and its own support line. When a credit view and a fraud view are generated separately, they must be reconciled instead of read together in the same instant. Every handoff is a place where a decision slows down and a signal gets missed. It's why a fraud pattern that would be obvious next to the credit file often surfaces only after the funds are already gone. Fragmentation also makes it harder to optimize lending strategies over time. When data, analytics and decisioning are disconnected, credit unions have less visibility into what's working, what's changing and where strategies need to be adjusted. An integrated decisioning ecosystem closes those seams by design, with credit, fraud and lending strategy running on one platform and accessed through a single Application Programming Interface (API). Identity and compliance capabilities can be an integrated decisioning flow. The data doesn't need to be reconciled after the fact because it was never separated in the first place. Stop overengineering, start removing friction When decisioning underperforms, the instinct is to build something more custom: a proprietary model, tighter segmentation, more configuration.  Custom modeling has its place for institutions with the scale and data to justify it. But often, for small or mid-sized credit unions, the bigger opportunity is a flexible decisioning strategy that uses a strong, continuously refreshed model. This shouldn't be either/or. The right approach gives credit unions a strong decisioning strategy today, with the ability to introduce more customized analytics and modeling as their needs evolve.  The same principle applies to strategy management: credit unions can gain greater control through self-service capabilities as they build a more sophisticated data science team.   That kind of flexibility is important as credit unions modernize their decisioning infrastructure. Research surveying more than 2,000 senior credit risk and fraud decision-makers across 11 countries found that organizations investing in unified platforms and modern infrastructure are moving faster and realizing the greatest Return on Investment (ROI).   As their needs evolve, credit unions can adjust decisioning strategies without introducing another layer of technology or relying on third parties to make every change. Until self-service is the right fit, choose a partner that understands what makes your credit union’s membership and risk appetite different from others.  Same member, same afternoon, faster answer Consider a credit union growing its auto and personal loan originations.  A member applies for an auto loan on Saturday afternoon. Credit data, identity and fraud signals are read together in a single real-time pass instead of separate reviews:  Most applications resolve immediately, approved or declined based on a more comprehensive view of the applicant. A smaller number are flagged for quick step-up verification and cleared within minutes. Only genuinely ambiguous cases reach an underwriter, who is working from one complete picture instead of reconciling multiple signals. The member has an answer before the weekend is over. The credit union books the loan before competitors even open on Monday. Built to scale This kind of process holds up today. However, the better test is whether it holds up eighteen months from now when application volume has grown, new products are live and the data flowing through the system looks nothing like it does right now. Future-proofing isn't only about handling more volume. It's about having room to be nimbler and make adjustments as quickly as the market changes. A credit union that relies on standard models within a decisioning strategy may want more customized analytics and greater control over its strategies tomorrow. Connect with us With more than three decades of credit expertise and one of the industry's largest data footprints, Experian helps credit unions do more than solve this year's friction. We're helping to build a decisioning foundation that scales, so growth becomes something the system absorbs, rather than something it must be rebuilt around. Explore More
