Tech Insights: Vital Cybersecurity Tips for Gadget Users

The digital economy in Nigeria is rapidly evolving, significantly impacting transactions and communication methods. However, this transformation has also triggered a surge in cybercrime, resulting in estimated annual losses of approximately $500 million. This alarming trend underscores the urgent need for effective cybersecurity measures among users.

Common Cyber Threats in 2026

As technology progresses, cyber threats are growing more sophisticated and frequently powered by artificial intelligence. In Nigeria, phishing scams have emerged as a significant concern, using platforms such as WhatsApp, SMS, and counterfeit banking applications to deceive users. Victims often disclose sensitive information, including passwords and bank details.

Types of Cyber Threats

• Phishing: Deceptive messages designed to extract personal information.
• Ransomware: Malware that locks data and demands payment for access.
• Malware and Spyware: Software aimed at stealing information or disrupting operations.
• AI-Powered Scams: Utilization of deepfake technology for impersonation and fraud.

A report from Deloitte Nigeria highlights an increasing trend in ransomware incidents and phishing attacks, largely stemming from a rise in online transactions. Urban areas, particularly Lagos, pose heightened risks due to widely-used public Wi-Fi networks, where attackers can intercept unsecured connections.

Basic Security Habits for Users

Implementing robust digital hygiene practices is essential for averting common cyber threats. Here are essential steps users should follow:

• Create Strong Passwords: Use unique passwords for different accounts; consider a password manager for additional security.
• Enable Two-Factor Authentication (2FA): Use authentication apps or hardware keys instead of SMS for added protection.
• Keep Software Updated: Regularly update systems and applications to close security gaps.

These simple but effective practices can diminish the risk of phishing, malware infections, and unauthorized access to accounts.

Securing Devices

Mobile devices and laptops are prime targets for cybercriminals. To enhance their security, users should:

• Download apps exclusively from reputable sources.
• Install antivirus software and enable firewalls on laptops.
• Change default passwords on smart devices immediately.
• Review app permissions to limit access to sensitive information.
• Connect smart devices to a separate Wi-Fi network for added security.

Safe Internet Use and Online Behavior

Many users inadvertently compromise their security by exposing confidential information. To protect personal data:

• Verify links before clicking and scrutinize URLs.
• Adjust privacy settings on social media to control who can view posts.
• Conduct financial transactions only on secure websites, indicated by “https” and a padlock icon.
• Avoid using public Wi-Fi for financial activities and confirm unfamiliar transaction requests through independent means.

What to Do If You Suspect a Hack

Monitoring accounts for suspicious activity is critical. If a breach is suspected, users should:

• Immediately change passwords and activate 2FA.
• Disconnect from the internet.
• Conduct a comprehensive antivirus scan.
• Notify the bank to suspend transactions if financial accounts are involved.

Regular data backups can also mitigate ransomware attack impacts. Additionally, reporting data breaches to relevant authorities like the Economic and Financial Crimes Commission helps in damage control.

As the cybersecurity landscape evolves in 2026, consistent protective measures are indispensable. By adopting strong passwords, ensuring regular software updates, and exercising caution online, users can significantly strengthen their security. In light of Nigeria’s expanding digital economy, personal vigilance is crucial for protecting devices, finances, and sensitive information.
