In a world where personal devices store vast amounts of sensitive information, protecting them from cyber threats is increasingly vital. With Nigeria ranked as the second-highest country for cyberattacks in Africa, following Kenya and ahead of South Africa, the risk of cybercrime is growing across the region. Data from the Kaspersky Security Network highlights the need for robust cybersecurity practices in Nigeria and similar high-risk areas.

Experts say financial motivations primarily drive these cyberattacks, with cybercriminals increasingly deploying advanced tactics such as phishing schemes and malicious software. Covenda AI’s cybersecurity expert, Faidat Abdullahi, emphasizes that identity theft is a significant cybercrime method, with attackers using stolen information to access accounts and commit fraud. Other methods include malware infiltration that can disrupt operations and steal data.

To help counteract these threats, here are several essential cybersecurity practices.

1. Keep Software Updated

Regular software updates are a foundational defense. They address known vulnerabilities that cybercriminals exploit. Enable automatic updates to ensure that your device has the latest protections, and look for timely updates from manufacturers like Apple, which frequently release patches to secure user devices.

2. Implement Strong Password Practices

Passwords serve as a first line of defense. Cybersecurity experts recommend using strong passwords combining uppercase and lowercase letters, numbers, and special characters. Avoid easily guessed information such as birthdays or names. Enabling two-factor authentication (2FA) offers an extra layer of security.

Kaspersky’s recent reports show a sharp increase—147%—in detections of Trojan-PSW (Password Stealing Ware) in Nigeria, underscoring the importance of password strength. SAP cybersecurity expert Chukwuka Madumere stresses that strong passwords are essential for securing both personal and business accounts.

3. Be Wary of Suspicious Emails and Links

Phishing attacks continue to rise, manipulating fear and urgency to push individuals into making hasty decisions. Common schemes include fake investment opportunities and emails offering essential information related to current events. Experts suggest verifying the authenticity of emails and links and being cautious with unsolicited messages, especially those demanding immediate action.

4. Secure Your Wi-Fi Network

A secure Wi-Fi network can shield devices from external threats. Abdullahi advises users to use robust, unique Wi-Fi passwords, enable WPA3 encryption if available, and change default router login credentials. Updating router firmware can help prevent vulnerabilities, while avoiding public Wi-Fi for sensitive tasks reduces the risk of interception.

5. Use Antivirus and Anti-Malware Software

Antivirus and anti-malware software add a layer of protection against malicious attacks. Though many Nigerians still refrain from investing in premium anti-malware solutions, such software offers critical protection by detecting and removing harmful programs that may otherwise go undetected.

6. Backup Important Data

In cases where data loss may occur due to malware, having a reliable backup system is invaluable. Regular backups ensure that data remains accessible in the event of a cyberattack, reducing reliance on ransomware demands and safeguarding against accidental deletions or system failures.

7. Educate Yourself on Cybersecurity Risks

Keeping informed on the latest cyber threats and best practices is essential for maintaining digital security. Understanding risks and emerging tactics gives individuals and businesses a better chance of preventing and mitigating attacks.

With increasing digital connectivity, these cybersecurity practices offer a proactive approach to protect devices and personal information from cyber threats. Staying informed, using strong passwords, and ensuring regular software updates can significantly bolster defenses against Nigeria’s growing cyber threat landscape.
