What is Account Takeover Fraud and How Can You Mitigate the Risk?

Account takeover fraud is a huge, illicit business in the United States with real costs for consumers and the organizations that serve them. In fact, experts predict that by the end of 2023, account takeover losses will be over $635 billion. With consumers’ data, your reputation, and your organization’s financial picture on the line, now’s the time to learn about account takeover fraud and how to prevent it. 

What is account takeover fraud? 

Account takeover fraud is a form of identity theft where bad actors gain unlawful access to a user’s online accounts in order to commit financial crimes. This often involves the use of bots. 

information that enables account access can be compromised in a variety of ways. It might be purchased and sold on the dark web, captured through spyware or malware or even given “voluntarily” by those falling for a phishing scam. 

Account takeover fraud can do far more potential damage than previous forms of fraud because once criminals gain access to a user’s online account, they can use those credentials to breach others of that user’s accounts. 

Common activities and tools associated with account takeover fraud include:

Phishing: Phishing fraud relies on human error by impersonating legitimate businesses, usually in an email. For example, a scammer might send a phishing email disguising themselves as a user’s bank and asking them to click on a link that will take them to a fraudulent site. If the user is fooled and clicks the link, it can give the hackers access to the account. 

Credential stuffing/cracking: Fraudsters buy compromised data on the dark web and use bots to run automated scripts to try and access accounts. This strategy, called credential stuffing, can be very effective because many people reuse insecure passwords on multiple accounts, so numerous accounts might be breached when a bot has a hit. Credential cracking takes a less nuanced approach by simply trying different passwords on an account until one works. 

Malware: Most people are aware of computer viruses and malware but they may not know that certain types of malware can track your keystrokes. If a user inadvertently downloads a “key logger”, everything they type, including their passwords, is visible to hackers. 

Trojans: As the name suggests, a trojan works by hiding inside a legitimate application. Often used with mobile banking apps, a trojan can overlay the app and capture credentials, intercept funds and redirect financial assets. 

Cross-account takeover: One evolving type of fraud concern is cross-account takeover. This is where hackers take over a user’s financial account alongside another account such as their mobile phone or email. With this kind of access, fraudsters can steal funds more easily and anti-fraud solutions are less able to identify them. 

Intermediary new-account fraud: This type of fraud involves using a user’s credentials to open new accounts in their name with the aim of draining their bank accounts. 
 
This is only an overview of some of the most prevalent types of account takeover fraud. The rise of digital technologies, smartphones, and e-commerce has opened the door to thieves who can exploit the weaknesses in digital security for their own aims. The situation has only worsened with the rapid influx of new and inexperienced online users driven by the COVID-19 pandemic. 

Why should you be concerned, now? 

Now that digital commerce and smartphone use are the norm, information used to access accounts  is a security risk. If a hacker can get access to this information, they may be able to log in to multiple accounts.. The risk is no longer centralized; with every new technology, there’s a new avenue to exploit.  

To exacerbate the situation, the significant shift to online, particularly online banking, spurred by the COVID-19 pandemic, appears to have amplified account takeover fraud attempts. In 2019, prior to the pandemic, 1.5 billion records — or approximately five records per American — were exposed in data breaches. This can potentially increase as the number of digital banking users in the United States is expected to reach almost 217 million by 2025.

Aite research reported that 64 percent of financial institutions were seeing higher rates of account takeover fraud than before COVID. Unfortunately, this trend shows no sign of slowing down.

The increase in first-time online users propelled by COVID has amplified the critical security issues caused by a shift from transaction fraud to identity-centric account access. Organizations, especially those in the financial and big technology sectors, have every reason to be alarmed. 

The impact of account takeover fraud on organizations 

Account takeover can be costly, damage your reputation and require significant investments to identify and correct. 

Protection of assets 

When we think of the risks to organizations of account takeover fraud, the financial impact is usually the first hazard to come to mind. It’s a significant worry: According to Experian’s 2023 U.S. Identity and Fraud report, account takeover fraud was among the top most encountered fraud events reported by U.S. businesses. And even worse, the average net fraud loss per case for debit accounts has been steadily increasing since early 2021.

The costs to businesses of these fraudulent activities aren’t just from stolen funds. Those who offer credit products might have to cover the costs of disputing chargebacks, card processing fees or providing refunds. Plus, in the case of a data breach, there may be hefty fines levied against your organization for not properly safeguarding consumer information. Add to these the costs associated with the time of your PR department, sales and marketing teams, finance department and customer service units. 

In short, the financial impact of account takeover fraud can permeate your entire organization and take significant time to recoup and repair. 

Protection of information 

Consumers rightfully expect organizations to have a solid cybersecurity plan and to protect their information but they also want ease and convenience. In many cases, it’s the consumers themselves who engage in risky online behavior — reusing the same password on multiple sites or even using the same password on all sites. These lax security practices open users up to the possibility of multiple account takeovers.

Making things worse for organizations, security strategies can annoy or frustrate consumers. If security measures are too strict, they risk alienating consumers or even generating false positives, where the security measure flags a legitimate user. 

Organizations are in the difficult position of having to balance effective security measures with a comfortable user experience.

Reputation 

When there’s a data breach, it does significant damage to your organization’s reputation by demonstrating weaknesses in your security. Fraudulent account take-overs can affect the consumers who rely on you significantly and if you lose their trust, they’re likely to sever their relationship with you. Large-scale data breaches can sully your organization’s reputation with the general public, making consumers less likely to consider your services.

How to build an account takeover fraud prevention strategy 

There are numerous ways to build an account takeover fraud prevention strategy, but to work for your and individual consumers, it must pair robust risk management with a low friction user experience. 

Here are some of the key elements to an account takeover fraud prevention strategy that hits the right notes. 

Monitor interactions

The risk of account takeover is constant so your monitoring should be as well. A layered, proactive and passive fraud prevention program can monitor your interactions, reduce false positives and keep track of consumers’ digital identities.

Use the right tools

When it comes to fraud prevention, you’ve got plenty of choices but you’ll want to make sure you use the tools that protect you, as well as consumer data, while always providing a positive experience. We use risk-based identity and device authentication and targeted step-up authentication to keep things running smoothly and only pull in staff for deeper investigations where necessary.

Automate to reduce manual processes 

Your organization’s fraud prevention strategy likely includes manual processes, tasks that are completed by employees—but humans make mistakes that can be costly. Taking the wrong action, or even no action at all, can result in a security breach. Automated tasks like threat filtering and software and hardware updates can reduce the risk to your organization while improving response time and freeing up your team. 

Choose a nimble platform 

Technology changes quickly and so does fraud. You’ll need access to a layered platform that lets you move as quickly as the bad actors do. 

The bottom line 

You can effectively mitigate against the risk of account takeover fraud and offer consumers a seamless experience. Learn more about account takeover fraud prevention and fraud management solutions

Rewriting the Road Ahead with Longer Loan Terms and Increased Refinancing Options

The automotive market is entering a new phase defined not just by what consumers are buying, but by how they’re choosing to finance it. According to Experian Automotive’s State of the Automotive Finance Market Report: Q1 2026, nearly one-third (35.55%) of all new vehicle loans now stretch more than six years, up from 30.83% in Q1 2025. Similarly on the used side, 31.54% of loans extended more than six years, an increase from 28.60% last year. The shift highlights why affordability is reshaping how consumers are financing their vehicles, particularly in larger and higher-priced vehicles. Refinancing gains traction as interest rates stabilize In addition to longer-term loans, consumers are becoming increasingly deliberate with their financing decisions and managing monthly payments as refinancing activity has gained momentum. For instance, consumers who refinanced this quarter lowered their interest rate by 2.2% and saved an average of $81 on their monthly payment. Credit unions, in particular, continued to play a major role in helping consumers secure more affordable payment options. In Q1 2025, credit unions accounted for the lion’s share of automotive refinancing at 63.43%, from 62.31% a year ago. By comparison, banks went from 23.51% to 22.59% year-over-year. Furthermore, those who refinanced with a credit union saved an average of $101 this quarter, whereas those who refinanced with banks saved $60. Expanding credit access through flexible financing Another notable trend this quarter was the incessant growth in subprime financing as credit accessibility across the market continues to increase. In the first quarter of this year, subprime borrowers made up 15.75% of total vehicle financing, from 14.40% last year. For new vehicles in particular, the subprime market went from 5.61% to 6.88% year-over-year, while subprime in used vehicle financing grew to 20.60% this quarter, from 19.36% a year ago. Increased activity in the subprime segment highlights continued confidence in the automotive market and underscores the importance of expanded financing options. As consumers seek greater flexibility with financing decisions that fit their lifestyle, lenders and dealers have the opportunity to approach them with more personalized solutions. These trends are helping keep both new and used vehicle markets moving forward, while creating new opportunities for consumers to manage payments and purchase confidently.

Staying Competitive After Trigger Leads Evolve: A Roadmap For Lenders

Trigger leads have long been the preferred solution for identifying high-intent mortgage borrowers. But with the implementation of the Homebuyers Privacy Protection Act (HPPA), which introduces new limitations and consumer protections around trigger leads, that playbook will need to shift. Now, lenders are quickly facing a pivotal shift in how they discover, engage, and convert prospective borrowers into customers. The industry now stands at a crossroads. Lenders who adapt early—leaning into predictive tools, consent-based engagement, and smarter prescreening—will redefine borrower acquisition in a more privacy-centric era.  HPPA: A structural change to mortgage marketing  The HPPA amends the Fair Credit Reporting Act by significantly restricting the use of mortgage inquiries for prescreen purposes. As of March 5, 2026, credit bureaus may only provide or utilize mortgage inquiries to:  End users with explicit borrower consent  The originator of the consumer’s current mortgage  The servicer of the consumer’s current mortgage  An insured depository institution or credit union where the consumer has an existing account  While these exemptions may provide continuity for banks and credit unions, many mortgage brokers and nonbank lenders will need to overhaul their prescreen practices—or risk being cut off entirely from a previously high-performing acquisition channel.  Why this isn’t just a compliance shift—It’s a strategic recalibration  Mortgage triggers in prescreen allow lenders to react instantly to consumer intent. Lenders rely on a prompt and convincing narrative to entice applicants to switch lenders. Mortgage inquiry triggers are effective and were, therefore, a prospecting strategy for many lenders. Recent legislative changes significantly restrict the availability of these inquiry triggers, and impacted lenders are focusing on a more intentional prospecting strategy to compete.   Without these mortgage triggers in prescreen, lenders need to ask:  Who are we trying to reach?  What early signals can we act on?  How do we earn permission and attention before a mortgage inquiry ever happens?  Transforming the funnel: From reaction to anticipation  The shift in mortgage inquiry-based prescreen isn’t the end of high-intent lead targeting. It’s the beginning of a more strategic and intentional approach—one that leverages earlier indicators of mortgage readiness and focuses on building relationships, not just closing transactions.  Here’s where the momentum is evolving, creating a new and smarter funnel:  Prescreen marketing: Using credit and behavioral attributes to help identify consumers who meet specific lending criteria before they signal active intent.  Predictive modeling: Leveraging propensity scores or custom models to prioritize outreach based on conversion likelihood.  Consent-based engagement: Implementing compliant mechanisms to capture and manage borrower opt-ins at scale.  The power of predictive modeling  According to recent industry interviews, propensity modeling is emerging as one of the most effective replacements for trigger-based prescreen. These models analyze hundreds of credit attributes—such as utilization, account mix, account age, and depth—to help identify consumers statistically more likely to seek a mortgage.  For lenders just beginning to use predictive modeling, off-the-shelf models can be a quick way to identify potential borrowers. For example, when layering propensity scores on top of credit eligibility, which can improve borrower targeting, many lenders see an increase in open mortgage loan rates.  Meanwhile, custom-built models, which analyze a lender’s own campaign performance over time, offer the highest level of precise targeting. These models isolate the attributes most predictive of conversions within a specific product mix—optimizing not just volume, but fit.  Speed without traditional triggers? It’s possible  One of the biggest concerns among lenders is maintaining the speed historically enabled by trigger leads. But that concern may be overblown.  Self-service prescreen platforms now allow marketers to generate qualified lead lists in as little as 24 hours, enabling rapid response during rate drops, competitive shifts, or seasonal demand spikes.   For those new to prescreening, batch campaigns still offer value, especially with analyst support.   Don’t overlook retention  In an era of intense acquisition competition, retention becomes a key differentiator.  Lenders who monitor property status, cash flow, and consumer credit behavior can proactively identify when an existing borrower is likely to list, refinance, or exit. Armed with that intelligence, lenders can re-engage with the borrower at the right moment—sometimes before a competitor is considered or contacted.  This level of behavioral intelligence may soon separate proactive lenders from reactive ones.  Actions instead of reactions  The evolution of trigger-based prescreen doesn’t just require new tools; it demands new thinking. Lenders should begin by auditing their current pipelines and determining:  What percentage of our acquisition is dependent on triggers?  What share of our book falls under the HPPA exemptions?  How will we scale compliant opt-in collection?  Are our current prescreen or modeling capabilities future-ready?  Those who answer these questions today—and act on them—won’t just be in compliance with the new laws, they’ll lead in a transformed market. Lenders should also be asking:   Do we have the infrastructure to collect and act on borrower consent?  Are our acquisition teams equipped to run prescreen campaigns — both batch and self-service?  What predictive models are we using (or could we use) to prioritize leads?  Are we proactively monitoring our portfolio to catch retention risks early?  How are we preparing our sales teams for longer, more consultative buying journeys?  Conclusion  The HPPA signals a shift away from relying on passive, inquiry-based prescreen acquisition and the beginning of smarter, more strategic engagement with potential borrowers. Lenders who embrace this transition early will find themselves not just compliant, but competitive—with deeper borrower insights, better conversion rates, and stronger long-term customer relationships.  The market is moving. The only question is: will you lead the change or chase it?  Citation  Experian. (2025, November).
