How do you know if your phone is hacked

If something feels ‘off’ with your phone, it most likely is a warning sign for something more sinister. You might’ve noticed that your phone has started having minor glitches. Perhaps it may restart itself throughout the day without any prompt. It may also constantly be warm to the touch, even when you haven’t used it excessively. 

You may even see that your GPS has enabled or disabled yourself, and your call log or messages inbox is filled with data you haven’t typed out. This is typically paired with greater data and internet consumption beyond your typical usage.

These odd snags are not glitches. They are the most common signs reported by users with compromised device security. One other evident and frightening sign is that you may simply lose access to all of your device’s features. 

7 ways Your Phone Can be Hacked

Now, it’s easier than ever to become a cybercrime victim. Since the industry is so fast-paced and dynamic, there are new advancements on a daily basis. This, unfortunately, means that hackers have an ever-growing arsenal of tools at their disposal. Here are the five most typical methods by which cybercriminals hack phones:


This is a type of software that works in the background of all of your applications. It tracks all of the keys pressed on your phone, which includes the information you type in, the applications you utilize, and more. Most often, this method is employed by hackers to collect users’ private information, such as their passwords or banking information.


These are some of the most dangerous methods of hacking. Trojans appear to be ordinary, unsuspecting applications on your phone. But, in truth, they are a type of malware virus that can collect, store, and extract your private data from your phone. This is especially sinister because of how hard it is for the average user to notice.

Adaptive Mobile

This method is unique as it targets a SIM card by transmitting a symbol to the victim’s device. When the message is received, hackers can spy on the device if the user clicks on the message. This method is more complex than most, and it runs in a very sophisticated manner as it can be used by cybercriminals to directly source information from your device.


Phishing is when cyber criminals impersonate a trustworthy source to gather information from unsuspecting victims. This can come through emails, messages, or even perceivably secure requests for personal data, such as passwords. When these requests are responded to, the hackers gain access to their victim’s device, allowing them to monitor, collect, or sell data as they wish to.

Spying apps

These apps mostly track their user’s location, call logs, and messages. They are helpful for parents who want to keep an eye on younger children using their devices, but they can easily be hacked by cybercriminals who can use that information for malicious purposes. There are many cases where hackers have utilized these apps to collect emails and sensitive data.

Hacking through a Mobile Phone Number

This is a more complex means of hacking, but it can be done. Through SS7 system signaling, hackers can record calls, forward calls, and even find out your location. 

Hacking Through Public Wi-Fi

By creating a hotspot that looks like a Public Wi-Fi or by hacking into an unsecured public network, a hacker can intercept traffic. This is known as a Man-In-The-Middle attack.

How your phone can be hacked

Symptoms that your phone is Hacked

Most of the tell-tale signs of your phone being hacked appear like glitches. But the fact is, these problems may just be the result of a serious problem. Some malware can deplete all of the resources of your device, limit the functioning of other apps, or even lock you out of your device entirely.

Performance Issues

If you’ve noticed that your device is sluggish out of nowhere, you could have a virus. Ask yourself if your battery doesn’t last as long as it usually does or if simple applications are taking longer to load. If your device is not behaving as it did before, you may have malware.

Your Phone Feels like it’s Running Hot

Performance issues are also linked with your phone being very hot to the touch. If your phone is hot even when it’s not being used, some sort of malware or mining app is likely being run in the background. This can also explain sudden battery losses or spikes in data use. 

Mystery Apps or Data

One of the most obvious signs of being hacked is finding data that you haven’t acted upon. If you come across an application you didn’t download, texts you didn’t write, or calls you didn’t make, it is likely that you’ve been hacked. If you notice anything you don’t recognize on your phone, it’s time to take action. 

Pop-ups or Changes to Your Screen

Sudden pop-ups are never a good sign when it comes unprompted. Any changes to your home screen or in your configuration can be a big hint that your device has been compromised.

How to Recover Your Phone After Being Hacked

Most of the time, booting your phone up in Safe Mode to delete the malicious app is the perfect fit. But there are many times when we don’t know what app is causing the problem. Here are some other tips for recovering your phone.

How to recover your phone after being hacked

Change Your Password

Make sure you don’t use the same password for different websites. Always try to incorporate special characters into longer passwords to make them over ten characters. Also, put a reminder in your calendar that tells you to change your password every 6 to 8 months, just to fully secure your device.

Install and Run an Anti-malware Software

An anti-malware software does everything you need it to do. It can not only identify the source of the problem but also get rid of it entirely. The most effective results come from preventative measures, so make sure to run this software regularly.

Turn Off Your Mobile Data and Wifi

It’s never a good idea to connect to a public Wi-Fi or to have your phone automatically connect to one, especially without a VPN. AstrillVPN is one of the best and most complete security solutions that are available on the market. It can protect your identity and encrypt your data so that there can be no access point for hackers to infect your device. 

Remove all Third-party and Suspicious Apps

If you are unsure about where you’ve downloaded an application form, you should delete it. Any application that hasn’t been downloaded from the Google Play Store is dangerous to have on your phone. Ensure you also check all the privacy settings and application permissions for any suspicious behavior.

Restore Your Phone to Factory Settings

Resetting your phone to factory settings erases all of the data stored on your device. This reboot allows your phone to go back to its bare essentials, which means that anyone who has access to your device can no longer reach it. This is a relatively simple process and is one of the most effective options.

5 Tips to Prevent Your Phone from Being Hacked

Although there are multiple ways for a hacker to gain access to your phone to steal private and sensitive data, here are several preventative measures to consider taking:

Use a VPN to Protect Your Data Online

VPNs work in a way where that connects your device to a VPN server. AstrillVPN, for example, has hundreds of servers in over fifty countries. This means that whenever you connect to a VPN, you will be totally anonymous and untraceable. All of your data will also be encrypted, whether incoming or outgoing. 

Any hackers trying to hijack your device will ultimately fail. AstrillVPN will change your IP address, protect your data, and give you an incomparable experience of privacy when online.

Constantly Update your Phone and its Apps

Prevention is definitely better than a last-minute solution. Other than keeping your bases covered with anti-malware software, staying updated with your phone’s own security updates is essential. Make sure you keep all apps and services active with regular updates, as that keeps everything running smoothly and securely.

Use a Password Manager

A complicated password is one of the best defenses against hacking attacks. However, it can get troublesome to remember a variety of passwords. Using a password manager can fix this because you can use it to not only keep your passwords in a safe place but can also use it to create top-notch passwords for total security.

Refrain from Using Third-Party Apps

Third-party applications from the internet do not go through the stringent checks that Google Play has in place for applications on their platform. Many third-party applications often demand unnecessary permissions that grant them greater access to your phone than needed. Google Play also has security protocols in place that immediately delete any malicious app, which further protects your safety. 

Keep Your Wi-Fi and Bluetooth Turned off when not in use

Whenever you turn your Wi-Fi or Bluetooth off during inactivity, you are effectively shutting the door to any unwanted parties from entering your device. Prevention is absolutely key, so whenever you are traveling and don’t need to be connected to the internet, just turn the connectivity options off.
