How to block hackers from your phone


Hackers are out there, looking for the smallest chink in your armour that will enable them to sneak in the backdoor and steal your personal information or spy on your activities. For the capeless superheroes fighting cybercrime, it can seem like an impossible task to keep up with the new ways that criminals are attempting to hack into their victims’ devices. As a result, while the authorities are playing catch up with the cybercriminals, it is up to ordinary citizens to remain vigilant and block hackers as best they can. The question is, what can you do to stop them?

Here are our 10 tips to keep the hackers out:

1. Update your phone and apps

Despite the multitude of new tricks that criminals are using to hack into your phone, there are some tried and tested methods that are fairly reliable, such as taking advantage of outdated or unpatched operating systems. Manufacturers and app developers regularly release new updates to help protect against new security threats and vulnerabilities.

By regularly updating your phone software and apps, you can protect your device against incoming attacks. In some cases an update may block a hacker that already has access to your device, if their malware relies on out-of-date software or a jailbreak.

2. Enable 2-factor authentication for all your online accounts (Especially iCloud or Google)

A lot of people configure their phones to make things quicker and more convenient. For example, many people choose to back their files up on the cloud because it saves on physical storage. Whilst this might be a great feature to have in case your phone is broken or lost, it also means there is a duplicate copy of your device out there that could be hacked via another access point.

Using two-factor authentication, which is often built into cloud services, helps to protect your device from being hacked or data being stolen. As a rule, you should always use two-factor authentication to access your online accounts. This means that even if a hacker manages to crack your password, your account will still be safe and your backed up data secure.

3. Download a good security app

A good security app can help you block hackers from your phone as well as detect any malicious apps that may already be on there. On Android devices there are plenty of apps available on the Play Store, including our own Certo Mobile Security.

For iPhone users, iOS restricts security apps from carrying out virus scans, but they can check your security settings and identify signs of device tampering. If you want to do a complete device scan, then Certo AntiSpy allows you to run a full spyware and vulnerability check against any iPhone by connecting it to a computer via USB.

4. Use a complex passcode

This may seem obvious, but a strong passcode is the first line of defense against unauthorized access to your phone. Contrary to the popular stereotypes, most of the time a hacker will actually need physical access to your phone in order to install a malicious app. By making sure that your password is at least 6 characters and you don’t use something that is easily identifiable for you, you can add an extra layer of protection to your device. Once you have set your password, don’t share it with anyone else and where possible use biometrics such as fingerprint or face recognition.

5. Don’t connect to unsecured Wi-Fi hotspots

Hacking doesn’t always mean that some malicious app or code has been loaded onto your phone. Sometimes a hacker may create a malicious WiFi hotspot designed to eavesdrop on your internet traffic. That is why you should never connect your phone to an unsecured WiFi network, or one you do not trust. If you have no option other than to connect then make sure to use a VPN so your traffic is encrypted.

6. Only download apps from official app stores

Third party app stores can be tempting as they often contain free versions of paid apps or tweaked versions of existing apps which offer more features than the original. However, these apps are subjected to a much less rigorous approval process than any official app stores. Therefore, as a result, they are a common method used by hackers to distribute malware.

7. Factory Reset

As a last resort, performing a factory reset will stop or block any hackers who currently have access to your phone. Doing so will remove any spyware that has been installed on the phone but it also removes every trace of your account from the device. Make sure you create a secure backup of any important data before doing so.

8. Use intruder detection

Some apps for iPhone and Android offer an intruder detection feature to catch snoopers who have physical access to your phone in the act. For example, they can detect when an incorrect PIN is entered and either take a photo of the intruder or sound an alarm to alert you. This feature is available in Certo Mobile Security for Android, and will be coming soon to Certo Mobile Security for iOS.

9. Restart your phone periodically

Many hackers rely on your phone being left switched on for long periods of time, something which most of us do, in order to function. If you perform a restart, then it can stop a malicious app from working, which is especially true on iPhones. Therefore, restarting your phone periodically can be a good way to block any hackers that may be monitoring your movements.

10. Check your device for apps that are using your location, microphone or camera

A lot of phone hacking takes the form of a hidden spy app. These spy apps will typically need access to things like your microphone, camera or location in order to perform their function. Doing a quick review of the apps that have access to these features on your device can be an easy way to reveal a spy app. Both Certo AntiSpy (iOS) and Certo Mobile Security (Android) are able to tell you exactly which apps are using these features. You can also manually check yourself by reviewing the privacy/permission options in the Settings app on most phones.

All of these methods are good ways to mitigate the risks of hackers accessing your phone. However, if you want a more robust way to protect your devices, specialised security apps such as Certo AntiSpy (iOS) and Certo Mobile Security (Android) are a more secure way to spot and block hackers. In tandem with these methods, you are able to present a well armoured defence in the face of cybercriminals.
