Rising cyber fraud threatens Nigerian businesses amid digital expansion

As Nigeria’s digital economy continues to expand rapidly, cybersecurity experts are warning that increasing cyber fraud and online attacks are exposing businesses, financial institutions, and consumers to growing financial risks.

Industry reports indicate that cybercriminals are shifting from low-level scams to more sophisticated attacks targeting small and medium-sized enterprises (SMEs), corporate organizations, and critical digital infrastructure.

According to recent findings released by Deloitte and the Nigeria Data Protection Commission, Nigeria records thousands of cyberattack attempts weekly as digital adoption accelerates across banking, e-commerce, and online services.

Experts say the rise in attacks is closely linked to the country’s increasing reliance on digital platforms without corresponding investments in cybersecurity infrastructure and user awareness.

Cybersecurity analysts noted that phishing remains one of the most common methods used by attackers. Fraudsters increasingly deploy fake emails, SMS alerts, and cloned websites designed to impersonate banks, regulators, and company executives in order to steal login credentials and financial information.

Business Email Compromise (BEC) attacks have also become more common, with criminals infiltrating corporate communication channels to divert supplier payments into fraudulent accounts.

Many Nigerian SMEs are considered particularly vulnerable due to outdated systems, weak security practices, and failure to regularly update software applications.

Security experts estimate that the majority of successful cyber breaches in Nigeria involve some form of human error or social engineering, where employees are manipulated into disclosing passwords, One-Time Passwords (OTPs), or confidential business information.

The growing use of artificial intelligence by cybercriminals is also raising fresh concerns within the industry. Earlier this year, the Nigeria Computer Emergency Response Team issued a warning over the emergence of AI-driven fraud schemes, including the use of deepfake technology to impersonate company executives during virtual meetings.

Speaking on the trend, cybersecurity specialist Dr. Peter Obadare warned that rapid technological innovation without adequate security measures could expose businesses to severe financial losses.

“Innovation without security increases exposure to cyber threats. Organizations must prioritize cybersecurity as part of their core operations,” he said.

Financial institutions have also continued to strengthen digital security measures in response to increasing fraud attempts. The Central Bank of Nigeria has introduced stricter biometric verification and customer authentication requirements to reduce fraud across digital payment platforms.

Despite the measures, experts say mobile banking and online payment systems remain major targets for cybercriminals, particularly through SIM-swap fraud, phishing attacks, and account takeover schemes.

To strengthen protection, industry stakeholders are encouraging businesses to adopt multi-factor authentication systems, continuous network monitoring, and regular cybersecurity awareness training for employees.

The Nigeria Data Protection Commission has also continued enforcement of the Nigeria Data Protection Act, requiring organizations to report data breaches within 72 hours.

Analysts say that as Nigeria’s digital economy grows, cybersecurity preparedness will increasingly determine the ability of businesses to survive and compete in an evolving technology-driven environment.
