Artificial intelligence (AI) is often viewed as a force for good, automating tasks, aiding in diagnosis, and boosting productivity. Yet, every powerful tool can be misused. One of the most significant threats emerging in 2025 is AI-driven cyberattacks, particularly zero-day attacks. For Nigeria, investing in AI isn’t enough; we must also defend against risks that could undermine our digital progress.

What Are Zero-Day Attacks?
A zero-day attack refers to a security vulnerability in software or hardware that is unknown to the developers responsible for fixing it. Because, there’s no patch or defence yet, malicious actors can exploit such a flaw immediately – the “zero days” indicate there has been no time to prepare. As AI becomes increasingly capable, attackers are leveraging AI to discover, exploit, or even amplify these vulnerabilities at an unprecedented rate.

How is AI Amplifying the Threat?
1. Automated Vulnerability Discovery 
AI tools can scan enormous codebases looking for weak points. Where human coders might take weeks or months, AI can find holes in hours or even minutes!

2. Adaptive and Polymorphic Attacks
Some AI-driven attacks change their form or signature dynamically so that conventional defences, like signature-based antivirus, fail to detect them. They “morph” to evade detection.

3. Weaponised Disinformation 
Beyond purely technical attacks, AI can be used to generate fake yet convincing content (deepfakes and phishing emails) that facilitate social engineering. In some cases, a zero-day exploit is just the technical component of a broader attack.

4. Scale and Speed
Attackers can deploy AI-enhanced tools across wide networks, making large-scale attacks more feasible. While defenders scramble to patch vulnerabilities, malicious code spreads swiftly.

Why Nigeria Must Be Alert
Nigeria’s tech sector and digital infrastructure are experiencing rapid growth. Government services, fintech, health-tech, and agritech increasingly depend on software and connectivity. But with growth comes risk:
– Many start-ups and organisations use imported software, which may not be vetted for every edge case or vulnerability.
