Common Cyber Attacks in Nigeria in 2026

In early 2026, Nigeria has emerged as the most targeted country for cyber attacks in Africa. Organisations in the country faced an average of 4,701 cyber attacks per week in January 2026, a 12% increase from the previous year.

The most common and impactful cyber attacks currently affecting Nigeria in 2026 include:

1. AI-Powered Phishing and Social Engineering

Cybercriminals are increasingly using Generative AI to automate and scale deception.

Highly Personalized Scams: Attackers use AI to create convincing emails, fake voice calls (deepfakes), and tailored malware with minimal effort.

Deepfakes: Audio and video deepfakes are now regularly used to impersonate senior executives or regulators to authorize fraudulent transfers.

Prevalence: Phishing remains the primary entry point for over 90% of data breaches in the country.

2. Ransomware as a "Leverage" Tool

Ransomware has evolved from simple file-locking to a tool for operational disruption and data extortion.

Target Sectors: Banking, healthcare, and education are the most frequent victims.

Shift in Strategy: Instead of just encrypting files, attackers now focus on stealing sensitive data to use as leverage for months, even if a ransom is not initially paid.

Impact: Ransomware assaults saw a massive 287% increase in frequency leading into 2026.

3. Business Email Compromise (BEC)

BEC remains one of the most financially damaging threats to Nigerian businesses.

Credential Loss: Credential theft is now the No. 1 effect of phishing, allowing attackers to hijack legitimate business accounts.

Method: Attackers monitor internal communications for weeks before sending a perfectly timed, fraudulent invoice or wire transfer request.

4. Attacks on Critical National Infrastructure

Recent incidents have shown a growing focus on the systems that power the economy.
