Has your smartphone been hacked?  Here are nine control signals

Editor’s Note: This blog was provided to WRAL TechWire by Journalistic.org.


The world of technology has been sabotaged again, amid news that WhatsApp users have experienced a new form of fraud, potentially hijacking their accounts through a single phone call, exposing personal information such as private messages and contact lists.

As users become more adept at fraud, cyberattacks on mobile technology seem to be becoming increasingly sophisticated.

Global search trend data highlights 20,000 Google inquiries for “how to know if your phone is hacked”and then experts at Bespokesoftwaredevelopment.com (to provide a thorough checklist of 9 telltale signs to help identify if you’ve been the victim of a cyberattack.

Battery life is reduced

A reduced battery life is common the longer you have a phone. However, if your phone is relatively new and in good condition, there is a good chance that if your phone has been hacked, you will notice a significant battery drain.

The reason is that malware is installed on the device, which secretly uses the phone’s existing resources and apps, and transmits data back to the hacker or server.

Your phone gets hot

It is inevitable that overuse of the phone may cause it to feel a little warmer than usual. Although this is relatively normal, a clear sign that your phone is being hacked is that your device gets warm without this excessive use. This is again because a hacker will have installed malware running in the background, resulting in extra activity, causing the phone to overheat.

Background noise on calls

Some indicators may not be as obvious, but if your phone has been hacked, you may notice a lot of background noise, during a phone call or when the sound is on. This could be a sign that someone is listening in on your conversations, or that a hacker has gained access to your device.

Consistent pop-ups and mysterious browsing experience

Pop-up ads are relatively normal and we won’t often question their authenticity. However, the time to start asking if you’ve been hacked is if you start noticing constant pop-up ads, where adware has been triggered that forces your device to click on revenue-generating pages. You must also avoid clicking on links that ask for personal or financial information if it has not been verified or recognized.

Likewise, if your browser looks strange and every site you visit doesn’t look good, or you’ve been redirected to other sites, chances are you’ve been hacked. Again, best to always change your password and uninstall programs you don’t recognize.

Slow performance

As with anything else, the moment you download something a little dodgy, your device is bound to slow down, freeze frequently, crash, or simply fail. The same applies to malware, which in turn overloads the phone’s resources more than usual. You may also find yourself having to force restart your device to close apps that appear to run consistently despite closing them.

Apps, messages, outgoing calls you don’t recognize

Strong signs that your phone may have been hacked are an influx of unknown numbers, text messages and downloaded apps that use your details. Be careful as this could signal that you have been the victim of a data breach and it is important that you do not reply or respond to anything. If you suspect unusual activity, block the caller and report it as spam to your provider.

Another reason to avoid answering a number you don’t recognize is that they are often expensive numbers, with a high premium, all of the proceeds of which go directly back to the cybercriminal. So best to check monthly bills as well.

Data usage is unusually high

Most cell phone users want to know roughly how much data they use per month on average. Any unusual spikes could signal malware on your phone. Some warning signs include large data files being uploaded and apps usually taking a long time to load. All of this can come from spyware or malware running in the background, sending information back to the server it came from.

Suspicious activity on personal accounts

From social media apps to your emails, your personal data is vulnerable to hackers, and a clear warning sign your phone may have been hacked is suspicious activity on associated accounts. Look out for emails about your password being reset, or a security message about a new device being connected. Unless you have personally done any of these things, do not open any email, link or app.

It is best to change your passwords immediately by logging into your browser (off-device).

Your signal has disappeared

Known as a “port attack”, this is when you receive an alert or message from your mobile provider about a change to your account that you didn’t make. You will eventually lose your signal altogether, in addition to not being able to log into any bank accounts or your emails.

As soon as this happens, you must contact the police and say that you have been a victim of identity theft. And of course contact your supplier then with the police report.
