Executive summary
AI has given fraudsters deepfakes, synthetic identities, voice cloning and automated attack campaigns. Fintechs — with digital onboarding, API ecosystems and rapid product change — are among the most exposed. This article sets out why AI-enabled fraud is one of the fastest-growing risks in financial services, what Internal Audit must now cover, and the questions Boards and Audit Committees should be asking.
Artificial Intelligence is transforming financial services. It is also transforming fraud. Criminals now have access to technologies that were once available only to large, well-resourced organisations: deepfakes, synthetic identities, AI-generated phishing, voice cloning, real-time social engineering and fully automated fraud campaigns.
As fintech organisations accelerate innovation, fraud is evolving at an even faster pace. The question is no longer whether AI will be used by fraudsters — it already is. The real question is whether Internal Audit is evolving quickly enough to provide meaningful assurance. Our fintech advisory services are built around exactly this gap between the pace of innovation and the pace of assurance.
Fraud is becoming intelligent
Traditional fraud schemes relied heavily on human effort: manual reconnaissance, hand-crafted messages, one target at a time. AI removes those constraints. AI-enabled fraud is:
- Faster
- More scalable
- Highly personalised
- More difficult to detect
- Continuously adaptive
Fraudsters increasingly use AI to identify control weaknesses, bypass authentication, generate convincing documents and target customers and staff with attacks that no longer carry the familiar warning signs. Fraud risk management frameworks written for yesterday's typologies will not surface tomorrow's.
Why fintechs face greater exposure
Fintechs operate in environments characterised by:
- High transaction volumes
- Digital onboarding
- API ecosystems
- Open Banking
- Embedded finance
- Cloud-native infrastructure
- Rapid product innovation
These characteristics create enormous commercial opportunity. They also widen the fraud surface — more entry points, more third parties, more automated decisions and less human review per transaction. Boards seeking fintech advisory support frequently start here: understanding how digital fraud risk has changed since the last formal risk assessment.
Why Internal Audit must evolve
Traditional Internal Audit approaches — periodic, sample-based and retrospective — are no longer sufficient on their own. A modern Internal Audit function should evaluate:
- AI governance
- Fraud prevention controls
- Machine-learning models
- Third-party AI providers
- Cybersecurity resilience
- Digital identity controls
- Continuous monitoring
- Data governance
Internal Audit should provide assurance over whether the organisation is genuinely prepared — not simply whether controls exist on paper. That shift in ambition is the core of Internal Audit transformation, and it is reinforced by our Internal Audit advisory services and governance, risk and controls advisory work. It also builds on the themes explored in how Internal Audit should assess AI governance, risk and controls.

AI requires continuous assurance
Annual audits cannot keep pace with AI-enabled threats that adapt within days. Leading Internal Audit functions increasingly adopt:
- Continuous auditing
- Continuous control monitoring
- Advanced analytics
- AI-assisted anomaly detection
- Dynamic risk assessment
Assurance itself must become more intelligent. As argued in AI won't replace internal auditors, the advantage sits with auditors who use these tools well — not with the tools themselves.
Questions every Board should ask
Boards and Audit Committees should challenge management with questions such as:
- How is AI changing our fraud landscape?
- Which fraud scenarios are emerging?
- How are AI models governed?
- Are fraud controls tested against AI-driven attacks?
- Is Internal Audit equipped to assess AI risks?
- What assurance does the Audit Committee receive over AI governance?
Weak answers are rarely a sign of weak management; more often they signal that AI risk has outpaced the reporting framework. It is also worth testing the credibility of external advisers — see AI charlatans may be the biggest risk to your transformation.
Internal Audit is becoming more strategic
The future Internal Auditor will combine:
- Professional judgement
- Business understanding
- AI-enabled analytics
- Cybersecurity awareness
- Fraud expertise
- Governance insight
Technology strengthens assurance. It does not replace professional scepticism.
Conclusion
AI-enabled fraud represents one of the fastest-growing risks facing fintech organisations. Boards cannot rely on yesterday's assurance methodologies to evaluate tomorrow's threats.
Internal Audit must evolve alongside technology — combining stronger governance, continuous assurance, advanced analytics and independent professional judgement. The organisations that succeed will not simply adopt AI. They will strengthen governance as quickly as they strengthen innovation.
