Enhancing consumer protection in an era of rising cybercrime.

Fraudsters have exploited loopholes in Nigeria’s Bank Verification Number (BVN) system, stealing ₦329 million through the use of static images for enrolment. A report by the Nigeria Inter-Bank Settlement System (NIBSS) revealed that corrupt BVN agents registered still images of Nigerians and foreigners as live enrollees, allowing the creation of fraudulent accounts across microfinance banks, mobile money operators, and payment service banks. These accounts were then used for transactions involving the stolen funds before detection, prompting authorities to delete the fraudulently created BVNs and refer the agents involved for prosecution.

The report also highlighted a significant surge in fraud-related losses, which rose to ₦52.26 billion in 2024, a 350% increase from 2020. While the total number of reported Fraud cases dropped by 31% over the same period, financial criminals have adopted more sophisticated methods, targeting vulnerabilities in digital banking systems. Attempted fraudulent transactions in 2024 amounted to ₦86.36 billion, with actual financial losses soaring by 195% compared to the previous year. The increasing complexity of fraud schemes underscores the need for stronger Security measures in Nigeria’s financial sector.

CBN mandates financial institutions to report fraud within 24 hours.

In response to these concerns, The Central Bank of Nigeria (CBN) has mandated that financial institutions report fraudulent BVNs to NIBSS within 24 hours of detection. However, experts argue that this measure alone is insufficient to curb rising fraud incidents. They recommend adopting more advanced biometric verification systems, AI-driven fraud detection, and stricter oversight of BVN enrolment agents. Without comprehensive reforms, the risk of insider fraud and system exploitation will persist, further undermining trust in the country’s financial institutions.

Beyond BVN-related fraud, cybersecurity threats remain a growing concern as Nigeria continues its shift towards digital banking. The rapid adoption of cashless transactions has provided new opportunities for fraudsters to manipulate financial systems. Experts stress the need for enhanced real-time fraud detection tools that can analyse transaction patterns and flag suspicious activities. Strengthening multi-factor authentication processes and increasing public awareness about common financial scams could also help mitigate cyber risks.

Fraudulent BVN agents must face consequences.

To effectively combat these challenges, Nigeria’s financial institutions must prioritise stricter enforcement and accountability. BVN enrolment agents and bank officials found complicit in fraudulent activities should face swift prosecution, serving as a deterrent to others. Regulatory agencies must also impose harsher penalties on institutions that fail to implement adequate security measures. Transparent reporting of fraud cases and collaboration between financial regulators, law enforcement, and Technology experts could further enhance fraud detection and prevention efforts.

Additionally, banks must strengthen security Infrastructure to counter evolving cyber threats. Enhancing data encryption, deploying fraud-monitoring technologies, and enforcing stricter compliance frameworks are crucial to safeguarding financial assets. If these vulnerabilities remain unaddressed, financial losses could escalate, and public trust in Nigeria’s banking system may weaken. Additionally, consumers must be educated on recognising and avoiding fraudulent schemes, as awareness remains a key defence. A comprehensive approach that integrates regulation, technology, and public engagement will be essential in creating a more secure financial environment.

Overall, a proactive approach to financial security is essential for protecting consumers and ensuring economic stability. Strengthening anti-fraud measures and leveraging technological advancements will help Nigeria build a more resilient financial sector. The rising scale of financial fraud underscores the urgency of reforms, not just in BVN enrolment but across digital banking security. Without decisive action, fraudsters will continue to exploit system weaknesses, putting businesses and individuals at risk. Sustained vigilance, innovation, and stricter enforcement will be key to curbing these threats and restoring public confidence in the financial system.
