Everyone’s worst nightmare is losing their phone, and that’s not even the worst of it. What happens when your phone gets hacked?

Don’t worry! In this article, we will discuss everything from how to know if your phone is hacked, to actually solving the problem. By the end of the reading, you will become secure about the topic.

How to Know if Your Phone Is Hacked

Determining this is not a difficult task. Below are a few common signs that will indicate if phones are hacked.

Battery Draining Quickly

If your battery is depleting quicker than usual, it might be a sign. Phones that are hacked have a high battery consumption.

High Data Usage

A phone that is hacked will use more data compared to a secured phone, as hackers use them to install other malicious apps or steal data. Look for signs of higher data usage than normal.

Constant Spam Pop-ups

We all deal with pop-ups and ads now and then. If you’re facing them regularly, however, it may be due to adware on your phone; this is another strong sign of a hacked phone.

Texts or Calls You Didn’t Make

If your phone is showing texts or calls that you didn’t make, it’s an indication of a hacked phone. Hackers try to use your phone to communicate, which often leads to identity theft.

Slow Phone Performance

A phone that is hacked will have a lower performance. If you notice that your phone has a slow performance all of a sudden, it might be in trouble. This is usually because hackers will install malware on your device.

Apps You Don’t Recognize

This is important! Seeing apps on your phone that you have not installed and don’t recognize is a blaring sign that your phone is hacked.

Unusual Accounts Activity

Lastly, your device may be hijacked if you notice any unusual account activity or unauthorized access. Hackers try to gather you and your contacts’ information through your accounts. This also leads to compromised passwords.

DID YOU KNOW? According to several hacking statistics, there is a hacking attempt every 39 seconds in the United States!

How Can a Phone Be Hacked?

Now that we have discussed the different signs, let us understand how a phone can be hacked.

Through Malicious Apps or Links

Malicious apps and links make your device prone to hackers. By downloading such apps or clicking such links on the internet, you provide access to hackers and allow their malware to be downloaded. This is commonly known as phishing; hackers will lure you into opening a link or app and hack the device through that.

By Connecting on Public WiFi

We all love free wifi! It is the modern-day equivalent of winning a lottery. However, connecting to public wifi can make it easier for hackers to hack your phone.

Through a SIM Swap

A SIM swap is not something that happens physically. In most cases, the hacker will call your SIM provider and pretend to be you. They will then import your number to their cellphones and take your data.

Through Bluetooth

Just like public wifi, hackers can connect to your Bluetooth and get access to your smartphone. This usually happens in crowded places where you leave your Bluetooth on.

DID YOU KNOW? Phone hacking is also associated with identity fraud. Identity fraud statistics show that 1 in 15 people have been victims of identity fraud! For that reason, besides protecting your phone, you should focus on identity fraud protection.

Do Not Visit Unsecured Websites

Just like messages, you will come across many unsecured websites. Do not open them, or worse, do not give them permission to access your phone.

Do Not Store Sensitive Information on Your Phone

Remember the old days when people used to store their information in diaries? Well, maybe it’s time to follow them. If you don’t have any information on your phone, hackers will not be able to access anything.

Install Anti-Malware Software

Anti-malware software or a mobile security app will secure your phone against any hacking. They can block pop-up ads, warn you if you visit an unsecured website, and much more.
