Is Your Bank Ready for AI Banking Fraud?
May 28, 2025
AI banking fraud is one of the most serious risks to the stability of financial institutions of our generation.
When bad actors weaponize AI tools to defraud financial institutions, the results can be devastating. Deloitte recently predicted that Gen AI fraud could 3X current banking fraud losses by 2027.
Fraudsters utilize AI to enhance the scalability and effectiveness of existing fraud methods, as well as incorporate new, powerful techniques such as into their arsenal.
But you can defeat AI bank fraud.
Financial institutions fight back against AI banking fraud when they deploy authentication technology that makes a user’s identity un-hackable - even against bad actors using generative AI technology.
Live biometric authentication from IronVest is a powerful defense against AI banking fraud.
AI Banking Fraud Tool Sales Are Booming On the Dark Web
Perhaps you’ve heard of hacked versions of ChatGPT, like the GhostGPT tool, designed to make it easier to create malware.
The growth of AI usage in the legitimate world has been shadowed by a sharp rise in interest from criminal groups. A indicates a 219% increase in mentions of malicious AI tools and tactics on dark web forums.
Today's AI-powered fraudsters are hunting for tools that can:
Automatically launch sophisticated phishing and social engineering campaigns, complete with video and audio deepfakes that steal legitimate credentials.
Bypass traditional KYC processes and outsmart static biometric identity verification systems.
Crack passwords and credentials at scale.
The Better Business Bureau recently highlighted how criminals also use AI tools to search vast troves of already breached data to find new combinations of data points that will enable fraud.
“This stolen information is then used in the commission of a wide array of scams including credit card fraud, mortgage fraud, personal loan fraud and more,” Mary O’Sullivan-Andersen, president and CEO of the BBB in Southern Alberta and East Kootenay, told a reporter recently.
The result is that while we are seeing the rise of new generations of deepfakes, we are also witnessing the reinvigoration of traditional fraud methodologies.
When AI Meets Traditional Fraud: A Perfect Storm
With custom-made AI tools at their fingertips, fraud-focused individuals and criminal organizations can now:
Scale document forgery campaigns. Fraudsters can use AI to either generate extremely realistic documents, such as financial and company incorporation records or edit existing ones.
Spin-up synthetic identities. Criminals are blending real and fake data, names, addresses, social security numbers, and phone numbers to create identities that can pass automated credit checks and onboard with fintech platforms. We are that threat actors are purchasing data from individuals at scale to use in AI-augmented fraud campaigns.
Automate scam scripts. AI tools are being trained to mimic legitimate customer service agents or sales reps in real-time conversations, often luring victims into sharing sensitive information or transferring money.
Right now, businesses are experiencing the sharp end of this technological shift in terms of rising fraud rates:
1,033% surge in utility account fraud over the past year.
An almost 500% increase in student loan scams over the past year.
46% rise in personal document theft leading to identity theft in 2024.
The AI Banking Fraud Authentication Gap: Why Traditional Defenses Are Failing
So, what does this AI fraud revolution mean for your fraud team? In short, it's exposing the critical vulnerabilities in legacy defense systems.
Deepfakes, synthetic identities, scripted voice attacks - all can defeat or overload systems that rely on static checks, signal scoring, or one-time verification that only cover part of the customer journey. Fraud gets through, or legitimate users get blocked.
AI banking fraud is leading to the demise of the last generation of fraud defense technology.
Consider how mobile and internet banking currently operate. Until now, banks have depended almost exclusively on device and behavior-based fraud detection signals - monitoring user location, device status, and similar indicators. While some institutions use biometrics for user authentication, it's typically limited to the login moment alone.
Fraud gets through and is usually either:
Detected after the transaction completes or
The bank just eats the loss.
The alternative (stopping even higher numbers of suspect transactions) would completely erode the customer experience.
Here's why this approach is fundamentally unsustainable:
AI fraud will scale exponentially, but fraud detection capabilities won't.
As AI enables more sophisticated fraud attempts, including multi-vector attacks (e.g., deepfakes combined with synthetic identity fraud), traditional fraud detection systems will struggle to keep pace.
This creates an inevitable outcome: either soaring losses for banks or a defensive posture that declines legitimate transactions and services, frustrating customers and damaging relationships through false positives.
Banks Can Defeat AI Banking Fraud
The path forward requires a fundamental shift from fraud detection to fraud prevention during customer interactions.
This means taking customer verification back to its root: Identity.
Before digital banking, most banking transactions required an individual to be present during the transaction, such as account setup, during which time they would be physically assessed by the bank representative on the other end of the transaction. Fraud still happened, but it was far harder to deceive someone constantly watching to check that your identity was real.
The same methodology works for defeating AI-powered fraud in the 21st century. Continuous verification done digitally makes it much harder for AI fraud to succeed.
72% of security leaders say fraud prevention is either 'extremely important' or 'important' right now, according to KPMG.
This means moving away from signal-based detection and towards real-time biometric authentication and fraud prevention.
Real-Time Biometric Authentication: Your AI Fraud Defense
Real-time biometric authentication is in-session fraud prevention that uses continuous verification of a customer's identity as the core fraud signal.
It defeats most AI fraud techniques in several key ways:
Detects and blocks deepfakes with randomized liveness prompts, micro-expressions, and gaze tracking.
Prevents multi-vector attacks with continuous, layered biometric and behavioral analysis.
Provides uninterrupted, real-time user verification across the full session.
Stops automated fraud with boolean fraud signals based on live human presence.
Continuously binding the in-session identity of the user to their actual identity is critical for defeating AI-driven bank fraud.
Even when a bank uses biometric authentication at log-in or during step-up authentication, fraudsters can still hijack a transaction after a user's session has been authenticated.
Attack techniques, such as man-in-the-middle attacks (a core concern for 26% of companies currently, according to CompTIA), session hijacking, and device-level compromise malware, enable bad actors to compromise authenticated sessions.
Real-time biometrics thwart these attacks by establishing a continuous identity link between the user and the session, thereby eliminating any possibility of compromise.
It also eliminates friction by making authentication continuous. This is a far better solution to mobile banking authentication UX than traditional 2FA solutions.
