Globally, the vast majority of phone users utilise their devices for a variety of reasons. According to Statista, approximately 75% of users engage in texting, 60% use their phones for banking, and nearly 50% use them to navigate.
As smartphone use becomes more broad and diverse, the sophistication of mobile threats grows, making strong security measures more important than ever.
In December, Kaspersky cybersecurity experts discovered a highly advanced vulnerability in iMessage, underscoring the critical necessity for watchful mobile security measures.
Malware, phishing, unsecured public WiFi, and SIM swap attacks are all methods for compromising mobile phones.
Signs of a hacked phone include fast battery drain, unusual charges, unfamiliar apps, and unauthorised account access.
According to a statement from the National Information Technology Development Agency, fraudsters are increasingly using malvertising to spread various types of malware.
This includes crypto mining programmes that are subtly placed into reputable advertising networks and websites.
To protect personal information and prevent unauthorised access to mobile devices, it is critical to adhere to specified security requirements.
These methods can considerably improve the security of personal information and lower the danger of hacking.
1. Weekly reboots
According to the National Security Agency's Mobile Device Best Practices study, iPhone and Android users should turn off and on their phones once a week to protect themselves from infection.
Regularly shutting off and restarting devices can disrupt potential viruses and make it more difficult for hackers to exploit software flaws.
While this operation alone will not eradicate all security threats, it dramatically minimises the likelihood of malware remaining on the device.
2. Disable unneeded services.
The research recommends that users disconnect Wi-Fi, Bluetooth, and cellular services when not in use.
While these networking options are helpful, they can also be used by cybercriminals.
Disabling them when not needed can help to prevent unauthorised access and data interception, hence protecting personal information.
3. Avoid public Wi-Fi networks.
Connecting to public Wi-Fi networks is generally prohibited, as these networks frequently contain rogue access points that can intercept and gather data from unsuspecting users.
By avoiding public Wi-Fi and turning it off when not in use, users can greatly limit their vulnerability to malicious network attacks.
4. Regular software updates
Keeping phone software up to date is critical, as upgrades frequently include patches and solutions for known vulnerabilities.
Regular updates are crucial for preserving mobile security.
The research also emphasised the significance of updating software as soon as new versions are available.
Software updates frequently resolve security problems and provide patches for vulnerabilities, making them an essential component of mobile security.
The Nigeria Communications Commission also recommended updating mobile device software, using strong and unique passwords, activating two-factor authentication, and avoiding public WiFi networks.
5. Protecting microphones and cameras.
For those concerned about privacy, a case that covers the microphone and camera might add an extra degree of protection.
This avoids "hot mic" attacks, which occur when the microphone remains active without the user's awareness, as well as unauthorised camera access.
While it may appear implausible, cyber-intelligence professionals have shown that such attacks are conceivable, as proved by malware created by Israel's NSO Group.
6. Safe billing procedures.
Users are also advised to only use the charging cords and accessories that came with the phone or those purchased from reputable suppliers.
Public USB charging stations should be avoided since they can be exploited to deliver malware to devices. Bringing a portable charger while travelling is a safer option.
7. Use encryption.
Encrypting your device makes your data unavailable to unauthorised users. Furthermore, using a VPN (Virtual Private Network) establishes a secure, encrypted tunnel for your internet connection, which protects your online activities and privacy.
8. Downloading programmes from the correct sources.
Certain apps that handle sensitive data communicate over unprotected internet connections and rely on third-party servers, posing serious security risks to users.
According to NITDA, the sensitive data obtained by these apps not only allows access to user information, but it is also shared with third parties, jeopardising user privacy and security.
To prevent data misuse, NITDA advises against downloading programmes from third-party sources.
Official app stores have stringent security requirements and rules for developers. Prior to approval, apps are typically inspected for malware and other security problems.
It is vital for any potential user to read reviews and verify developer credentials to ensure validity.
The agency recommends ensuring that apps accessible for download in Nigeria have privacy policies that comply with the Nigeria Data Protection Regulation (NDPR).
It also recommended that users customise app settings to limit the quantity of personal information revealed.
By adopting these security precautions into their everyday routines, smartphone users can better protect themselves against the growing threat of cyberattacks and keep their personal information safe.
