Cybersecurity in Nigeria is no longer a concern reserved for large banks and telecoms. The threat landscape has democratised — and not in a good way. Attackers are now targeting mid-size businesses, schools, logistics companies, and government agencies with the same level of sophistication previously reserved for Fortune 500 corporations.
The Threats That Are Actually Hitting Nigerian Businesses
Business Email Compromise (BEC) remains the most financially damaging attack vector for Nigerian organisations. An attacker impersonates a senior executive or vendor, redirects a payment, and the money is gone before anyone notices. The Nigerian Communications Commission reported a significant uptick in these attacks targeting SMEs in 2024, a trend that continued through 2025.
Ransomware is the second major concern. Unlike BEC which targets finance teams, ransomware locks down entire IT systems and demands payment for restoration. Several Nigerian hospitals and logistics companies experienced operational shutdowns in 2024–2025 due to ransomware attacks on their legacy Windows environments.
Credential stuffing — where attackers use username and password combinations leaked from other breaches to gain access to your systems — is particularly dangerous for organisations that have not enforced strong password policies or multi-factor authentication.
The Root Cause Most Organisations Miss
Most of these attacks succeed not because of sophisticated technical exploits, but because of weak authentication practices and a lack of visibility into who is accessing what, when, and from where. An attacker who gets a valid username and password faces no friction in most Nigerian enterprise environments. There is no policy checking whether that login is happening at 2am from an unusual location. There is no alert when the same credentials are used from two countries in the same hour.
This is precisely the problem APESS was built to solve — not by replacing your existing systems, but by wrapping them in a layer of intelligent authentication enforcement and audit capability that makes these attacks visible and preventable.
Three Things You Can Do This Week
First, audit who has administrative access to your systems. You will almost certainly find accounts that should have been deactivated months or years ago. Second, enforce a password change policy — anyone who has not changed their password in 90 days is a risk. Third, enable login logging on every system that supports it. You cannot respond to what you cannot see.
