What if you left your phone behind in a public place? Without a passcode on the lock screen, its contents would be fully accessible to anyone who had it. Configure a passcode, along with other even more secure options such as a fingerprint or facial recognition scan, if available on your device.

Have you ever wondered if someone was secretly listening to your conversations? Many mobile apps, including hundreds of popular games, do exactly that, by scanning for ambient audio cues to better target their advertisements. For your own privacy, consider disabling microphone access for such applications unless you’re actively using it in them.

Don’t panic – follow these best practices after a hack and you can protect yourself.
