Exposing the Dark Side of Digital Progress: Nigeria's Escalating Online Banking Vulnerabilities

Nigeria's digital landscape is under siege, with the country experiencing over 4,000 cyber attack attempts weekly, according to the National Commissioner of the Nigeria Data Protection Commission, Dr. Vincent Olatunji.

n

This staggering figure is a stark reminder of the vulnerabilities that exist within Nigeria's rapidly expanding digital economy, where millions of transactions take place daily across various platforms.

n

Louisa Olaniyi, a media practitioner, recently found herself at the receiving end of a failed transaction, where a debit alert appeared instantly on her phone, only to have the money quietly reversed into her account hours later.

n

This incident exposed a troubling reality within Nigeria's digital payment ecosystem, where consumers are often left trapped between banks, fintech companies, telecom providers, and switching platforms, each shifting responsibility whenever transactions fail.

n

Behind every transfer, Point-of-Sale, PoS, payment, USSD transaction, mobile wallet, National Identity Number, NIN verification, or fintech application lies a vast digital public infrastructure, DPI, quietly powering Nigeria's modern economy.

n

Digital public infrastructure refers to foundational digital systems such as identity platforms, payment rails, telecom infrastructure, and data exchange systems that enable citizens, businesses, fintech firms, banks, and government agencies to interact digitally.

n

In Nigeria, the infrastructure now supports millions of transactions daily across banking, telecommunications, e-commerce, healthcare, education, transportation, and government services, with electronic payment transactions on the NIBSS Instant Payment, NIP, platform hitting an all-time high of N1.07 quadrillion in 2024.

n

This represents a 79.6 percent growth from N600 trillion recorded in 2023, with financial inclusion also improving significantly, as formal financial inclusion rose to 64 percent in 2023 from 56 percent in 2020.

n

Overall financial inclusion increased to 74 percent from 68 percent over the same period, driven largely by the growth of fintech services, mobile banking, and agency banking networks, according to the 2023 Access to Financial Services Survey released by Enhancing Financial Innovation and Access, EFInA.

n

However, experts warn that the same infrastructure driving inclusion is also exposing dangerous vulnerabilities, as failed transfers and fake debit alerts continue to erode public confidence in digital financial systems.

n

For Nsika Samuel, a simple transfer became a two-day nightmare, as he transferred money from his Providus Bank account to an OPay account to pay for goods he purchased, only to have the recipient never receive the money.

n

Samuel eventually recovered the trapped funds after a friend, who worked as an account officer, intervened, highlighting the growing ecosystem of fear, confusion, and weak consumer protection behind Nigeria's booming fintech sector.

n

Industry figures reveal the scale of the crisis, with financial institutions in Nigeria losing N52.26 billion to fraud in 2024, up from N17.67 billion in 2023, representing an increase of about 196 percent, according to the latest NIBSS fraud report released in February 2025.

n

The report further showed that although reported fraud cases declined from 101,624 in 2020 to 70,111 in 2024, the actual value lost rose sharply, indicating that fraud incidents are becoming more financially devastating.

n

Cybersecurity experts say the surge mirrors the explosive growth of Nigeria's digital payment ecosystem and expanding cyberattack surfaces, with Lagos accounting for over 60 percent of reported fraud activities.

n

For small business owners and PoS operators, the consequences are often devastating, as they find themselves trapped between customers and platforms, with Mrs. Kemi Ogunwale, a Lagos trader, recalling how a customer showed her what appeared to be a successful transfer after her Moniepoint terminal developed network problems.

n

Mrs. Rosemary Obong, a PoS operator in Ajah, Lagos, lost money after unknowingly accepting counterfeit cash from a customer, highlighting the fragile structure supporting Nigeria's rapidly expanding digital finance ecosystem.

n

PoS operators and customers are becoming targets of organised cybercriminals exploiting weak digital literacy and public trust, with an Abia State-based PoS operator narrating how fraudsters attempted to deceive her into releasing sensitive banking information under the guise of a system upgrade.

n

Chairman of the Lagos Chapter of the Association of Mobile Money and Bank Agents in Nigeria, AMMBAN, Mr. Ibirogba Oluwagunwa, said consumers are bearing the greatest burden of unresolved digital payment failures, with failed USSD transactions being a major concern.

n

According to him, one of the biggest concerns remains failed USSD transactions where customers are debited without successful transfers or timely reversals, with millions of Nigerians using USSD daily because many are not tech-savvy enough for banking apps.

n

National Vice President of AMMBAN, Mr. Yusuf Adeyemo, said many agents often refund customers from personal funds to avoid harassment while waiting endlessly for service providers to resolve disputes, describing it as a "tug of war" between agents, customers, and service providers.

n

Cybersecurity and digital trust expert, Prof. Peter Obadare, warned that weak digital trust now threatens Nigeria's financial inclusion agenda, with the "big elephant in the room" being cybersecurity and electronic fraud.

n

Regulators are beginning to strengthen collaboration around Nigeria's digital public infrastructure, with the Nigerian Communications Commission, NCC, and the Central Bank of Nigeria, CBN, signing a Memorandum of Understanding aimed at strengthening consumer protection and tackling electronic fraud.

n

Executive Vice Chairman of NCC, Dr. Aminu Maida, said the initiative would help financial institutions verify phone numbers in real-time to reduce fraud linked to SIM swaps and recycled numbers, giving them better visibility and equipping them to respond more effectively to e-fraud involving mobile numbers.

n

CBN Governor, Mr. Olayemi Cardoso, said the partnership would help build a safer and more resilient digital financial ecosystem, with the goal of delivering a safer, more resilient, and inclusive digital financial system that protects consumers and strengthens trust.

n

Head of Strategic and Research at NIBSS, Mr. Williams Uko, explained that while Nigeria's instant payment infrastructure processes transactions within milliseconds, failures can still occur when one participating institution experiences downtime, highlighting the need for a dispute resolution platform to address such failures.

n

For ordinary Nigerians already battling inflation and economic hardship, every failed transfer or trapped transaction carries emotional and financial consequences, yet digital payments have become unavoidable in daily life.
