Mobile devices keep us connected to our family, the news, and information anywhere, but that also makes them prime targets for cybercriminals. A 2023 report by Zimperium, a mobile device and app security company, found that between 2021 and 2022, 80% of phishing attacks specifically targeted mobile devices. Phishing is when a cyber-criminal sends you a fake email or text message designed to trick you into revealing sensitive information or downloading a virus.

So, what can you do to protect yourself from mobile cyber-attacks? Follow these tips to help safeguard your personal data and digital identity.

1. Protect your device with a screen lock

Use a screen lock that requires a password, personal identification number (PIN), or biometrics (fingerprint, facial recognition). This is a simple way to protect your mobile device and it will ensure that if your device is lost or stolen, others won’t be able to access any data you have stored on it. Learn more about creating strong passwords.

2. Keep your device physically secure

Mobile devices help us stay connected on the go, but they are easy to lose. Always keep your device with you and store it securely when not in use. Do not leave devices unattended in public locations, such as restaurants and airports.

3. Stay up to date

Regularly update the operating system of your mobile device to improve performance or patch security vulnerabilities. Outdated software can allow hackers to steal data from your mobile device. Turn on automatic updates to make it easy to stay protected.

4. Disable wireless access when not in use

Hackers can use Bluetooth or WiFi to gain unauthorized access to your mobile devices. Keep an eye on the Bluetooth or WiFi feature of your device in public locations and disable it if needed to reduce the possibility of an attack.

5. Use caution on public WiFi

Public WiFi can be insecure. Connect to networks that you can associate with a physical location. Confirm the WiFi network with the businesses you visit (like a coffee shop, office, or restaurant). Disable auto-connect features to stop your device from connecting to a network without your knowledge. Avoid using sensitive information, such as passwords and credit card numbers, on public WiFi. Protect your data with encryption services such as virtual private networks (VPNs). Following some ground rules will help protect your devices on public WiFi. 

6. Only use official app stores

Download apps directly from the Apple App Store or Google Play. They frequently scan apps for malicious behavior, and while not perfect, it greatly reduces the chance of downloading malware. It’s also a good idea to check the ratings and reviews of an app, as well as its privacy policy, before downloading.

By following these tips, you will significantly reduce the chances of your data falling into the wrong hands. Remember that technology is constantly changing, and you need to stay vigilant to keep your data and digital identity secure.
