Smartphones are used for many tasks around the world. According to Statista, about 75% of people use their phones for messaging, 60% for banking, and nearly 50% for navigation. As smartphones become more popular and versatile, the threats to them also increase, making it essential to follow strong security practices.
Smartphones can be attacked in various ways, including through malware, phishing, unsecured public WiFi, and SIM swap attacks. Common signs that your phone might be hacked include sudden battery drain, unexpected charges, unfamiliar apps, and unauthorized access to your accounts.
According to the National Information Technology Development Agency (NITDA), cybercriminals are increasingly using malvertising to spread different types of malware. Malvertising involves hiding harmful scripts in legitimate ads and websites to infect users’ devices.
Also, Kaspersky cybersecurity experts found a serious vulnerability in iMessage, showing how important it is to stay vigilant about mobile security.

To protect your personal data and keep your phone secure, you should follow these important security tips:
Weekly Reboots
The National Security Agency’s Mobile Device Best Practices report recommends that both iPhone and Android users restart their phones once a week. Regularly turning your phone off and on can disrupt potential malware and make it harder for hackers to exploit software vulnerabilities. While this alone will not fix all security issues, it greatly reduces the risk of malware staying on your device.
Disable Unused Services
It is advised to turn off Wi-Fi, Bluetooth, and cellular services when you are not using them. These features can be entry points for cybercriminals, so disabling them when they are not needed helps prevent unauthorized access and data interception.
Avoid Public Wi-Fi Networks
Public Wi-Fi networks can be dangerous because they may have rogue access points that can collect your data. To stay safe, avoid using public Wi-Fi and turn off Wi-Fi when you are not using it. This can greatly reduce the risk of falling victim to malicious network attacks.
Regular Software Updates
Keeping your phone’s software up-to-date is very important. Updates often include security patches and fixes for known vulnerabilities. The National Security Agency’s report emphasizes that you should install updates as soon as they are available to address security flaws and protect your device.
The Nigeria Communications Commission also recommends keeping your software updated, using strong and unique passwords, enabling two-factor authentication, and avoiding public Wi-Fi networks.
Protect Microphones and Cameras
If you are worried about privacy, consider using a case that covers your phone’s microphone and camera. This can prevent “hot mic” attacks where the microphone is activated without your knowledge and stop unauthorized access to your camera.
Safe Charging Practices
Always use the charging cords and accessories that come with your phone or buy them from trusted manufacturers. Avoid public USB charging stations because they might be used to introduce malware into your device. A safer option is to bring a portable charger when you travel.
Use Encryption
Encrypting your phone ensures that your data is protected from unauthorized access. Additionally, using a VPN (Virtual Private Network) creates a secure, encrypted connection for your internet activities, helping to keep your online actions private.
Downloading Apps from Trusted Sources
Some apps handle sensitive information and may use unsecured internet connections or third-party servers, which can be dangerous. NITDA advises against downloading apps from third-party sources. Stick to official app stores where apps are checked for malware and security issues before being approved. Always read reviews and check the developer’s credentials to make sure the app is legitimate.
Make sure the apps you download in Nigeria have privacy policies that comply with the Nigeria Data Protection Regulation (NDPR), and adjust app settings to limit the amount of personal information you share.
Follow these security measures to better protect your smartphone from cyberattacks and keep your personal information safe.
