A surge in account takeover attacks are forcing fintech companies to move beyond traditional security systems, with artificial intelligence increasingly emerging as the frontline defence against digital financial crime.
As digital payments become a daily part of life for millions of Nigerians, cybercriminals are deploying more sophisticated and automated methods to target consumers and financial institutions. Industry data shows that account takeover remains one of the most persistent threats, contributing significantly to banking-related fraud losses reported across the sector.
The scale of the challenge is growing rapidly. Between early 2023 and mid-2025, Nigeria’s financial services industry is estimated to have lost hundreds of billions of naira to digital fraud. At the same time, more than 281,500 user accounts were exposed through data breaches and leaks in the first quarter of the year alone, underscoring the expanding attack surface created by digital financial services.

The increasing sophistication of cyber threats is changing how fintech firms approach security. Rather than relying on passwords, one-time passwords (OTPs), or isolated fraud controls, leading operators are adopting a more holistic security framework that combines artificial intelligence, behavioural analytics, biometric verification and real-time monitoring.
