Introduction
The internet has transformed the way we live, work, and socialize. From banking online to shopping, learning, and freelancing, Nigerians rely on the internet more than ever. But with convenience comes risk. Cyber threats like phishing, scams, malware, and identity theft are rising rapidly. In 2026, staying safe online isn’t optional—it’s essential.This guide provides practical tips, tools, and strategies to help you protect your data, devices, and privacy while navigating the digital world.
1. Understanding the Top Online Threats.
Before you can protect yourself, it’s important to know what you’re up against.
a) Phishing & Scams
Phishing is when scammers trick you into revealing personal information, like passwords or bank details, by pretending to be a trusted entity. Common examples in Nigeria include fake banking messages or “job offer” emails.
Tip: Never click on links in unsolicited emails or messages. Always verify the sender.
b) Malware & Ransomware
Malware is malicious software that can steal data, damage devices, or even lock you out of your system. Ransomware specifically locks your files and demands money for release.
Tip: Use reputable antivirus software and avoid downloading files from untrusted sources.
c) Data Breaches
Data breaches occur when hackers access sensitive information from companies or platforms. Nigerian banks and online services have occasionally experienced breaches that expose personal data.
Tip: Change passwords regularly and avoid using the same password across multiple accounts.
d) Social Engineering
This involves manipulation to gain access to personal information. For example, someone might impersonate a bank officer to extract your login credentials.
Tip: Always question unexpected requests for information.
