AI in Financial Services: The Battle Between Agents and Attackers

Fraud in financial services has evolved into one of the most critical risks of our time. What was once opportunistic crime has now transformed into an organized, scalable, and highly sophisticated industry powered by emerging technologies.

According to UK Finance, fraudsters stole £1.17 billion in 2023, with banks managing to block another £1.25 billion using advanced security measures. More than 2.7 million fraud cases were reported, while the UK Government’s 2024 Cyber Security Breaches Survey revealed that 50% of UK businesses experienced a cyberattack or breach, up sharply from 39% in 2022.

Across the Atlantic, the US Federal Trade Commission (FTC) disclosed that consumers lost over $12.5 billion to fraud in 2024, a 25% year-on-year increase. Investment scams accounted for $5.7 billion, while imposter scams caused losses of $2.95 billion. Fraudsters most frequently exploited bank transfers and cryptocurrency transactions.

This surge highlights a dangerous new reality: fraud has become a global enterprise, enabled by “fraud-as-a-service” kits, automation, and—most recently—artificial intelligence (AI).

The Attacker: AI-Powered Deception at Scale

Financial fraud in 2025 is no longer the work of lone cybercriminals—it is driven by entire ecosystems operating like lean tech startups. In the U.S. alone, identity fraud cost $43 billion in 2023 (AARP). Stolen credentials, synthetic identities, and deepfake toolkits are now packaged and sold like off-the-shelf software.

Generative AI has supercharged this model:

• Deepfake scams have already caused nearly $900 million in losses.
  
• Voice cloning fraud has emerged as a major threat, tricking executives, bank officials, and even families with highly convincing synthetic audio. In one high-profile case, fraudsters cloned a CEO’s voice to authorize a fraudulent transfer of $243,000.
  

The World Economic Forum (2025) warns that generative AI tools have made real-time deception accessible to virtually anyone. These attacks are cheaper, faster, and more scalable than ever before, escalating the attacker’s side of the arms race.

The Defender: Agentic AI as the Front Line

To combat industrial-scale fraud, financial institutions are deploying agentic AI—specialized AI systems designed for real-time detection, authentication, and automated response.

Key advancements include:

• Voice fraud detection: Deepfake scams in Europe have grown 2,137% in three years. Platforms like Pindrop have processed over 3 million fraud events, preventing an estimated $2 billion in losses.
  
• Behavioral analytics: Security teams are shifting from reactive case handling to proactive monitoring of system-level fraud patterns, helping detect coordinated attacks before they scale.
  
• Domain-specific AI: Unlike generic models, financial-grade AI solutions such as Fulcrum Digital’s FD Ryze integrate compliance, anomaly detection, and regulatory safeguards tailored to banking environments.
  

Still, detection remains imperfect. Both AI systems and human analysts experience accuracy drops of up to 50% when exposed to real-world deepfakes. This makes AI governance and operationalization just as important as the technology itself.

Agentic AI in Action

Agentic AI is already transforming fraud prevention in financial services:

• Apex Fintech Solutions uses AI agents for real-time threat detection across millions of customer interactions.
  
• Torq automates phishing investigations, device fingerprinting, and endpoint remediation through AI-driven playbooks.
  
• Fulcrum Digital’s FD Ryze leverages micro-agents for compliance checks, anomaly detection, and fraud alerts—all without disrupting customer experience.
  

These systems prove that AI is not just a defensive tool but a strategic pillar for resilience, trust, and compliance in financial ecosystems.

Governance & Regulation: Building Trust Around AI

Unlike fraudsters, financial institutions must operate within strict regulatory frameworks. This makes AI governance crucial.

• In the UK, the Financial Conduct Authority (FCA) has introduced an AI sandbox where banks can test agentic AI under supervision.
  
• In the US, the SEC and DOJ are cracking down on “AI-washing,” penalizing firms that exaggerate AI capabilities or obscure accountability.
  

For banks and fintechs, explainability, auditability, and accountability are not optional—they are essential for building trust with regulators, customers, and boards.Governance, far from being a barrier, acts as a framework for confidence, ensuring AI systems are scalable, transparent, and aligned with institutional goals.

Conclusion

The financial services sector is witnessing a new kind of AI arms race: attacker AI vs. defender AI. Fraudsters are exploiting generative AI to scale deception, while banks and fintechs are deploying agentic AI to secure systems, protect customers, and preserve trust.

Success in this race will not depend solely on speed or sophistication—it will depend on responsible deployment, governance, and sector-specific innovation.

In a world where fraudsters have no rules, financial institutions must win by combining AI-powered defenses with regulatory compliance and customer trust.
