Internal fraud, the Achilles heel of Fintech

The digital transformation that Fintechs have led in recent years promises accessibility, speed, and financial inclusion, but at the same pace, risk has also become more sophisticated. Within an ecosystem that operates on data and automation, fraud and insider threats are no longer isolated incidents: they are structural vulnerabilities.

Safety culture: a pending debt

One of the most worrying factors is the poor culture of data protection, not only within Fintech companies but also in the societies surrounding them. Cases like that of Hong Kong in 2024 , where sensitive information about job applicants was used for identity theft, demonstrate how easy it is for malicious actors to build comprehensive profiles with publicly available data.

In Singapore , a government agency mistakenly posted thousands of NRIC IDs on a public portal. Although access was restricted days later, the automated search engines had already done their work. The consequences were immediate: banks changed authentication policies, and citizens had to change passwords based on that data. ( FinTech – What's New and What's Needed, 2025 )

When the threat doesn't come from the hacker... but from the collaborator

Insider fraud is a silent threat. Often disguised as human error or negligence, it has real impacts: from credential leaks to unauthorized payments. According to the World Economic Forum's Global Cybersecurity Outlook 2025 , 71% of cyber leaders believe that small and medium-sized organizations have already crossed the threshold where they cannot protect themselves from the rising level of cyber risk.

And while regulations seek to strengthen resilience, their fragmentation adds further complexity. More than 76% of CISOs surveyed say this fragmentation directly affects their ability to comply with regulations.

AI

Fraud cases involving generative artificial intelligence (AI) are on the rise. To counter this, technologies are emerging that utilize biometrics for increased security. Although more secure than traditional systems, they also pose a new challenge: the irreversibility of damage . A credit card can be replaced; your veins cannot. Biometric authentication, while powerful, requires additional layers of backup and liveness detection to prevent impersonation.

The more processes become automated, the greater the risk of a vulnerability going undetected. This is where artificial intelligence also plays to the advantage of defenders: early detection, continuous monitoring, behavioral analysis, and automatic vulnerability classification become critical allies. There is already talk of "AI-CISO" -type assistants that optimize cybersecurity decisions with limited resources.

Surveillance from within

The future of the Fintech ecosystem depends not only on the solutions they implement to address external threats, but also on their ability to look inward. Trust cannot be blind. Organizations must accept that internal risk —whether intentional or accidental—is just as critical as an external attack.

The adoption of AI, biometric authentication, and behavior-based security models is key. But no technology will replace the need for a comprehensive security culture , a robust identity management strategy, and a clear "zero trust" policy within the organization as well.
