If you think about it, smartphones hold way too much confidential information than we could imagine. Plus, they have an access to multiple accounts via pre-logged-in apps.
So technically, if you were hacked, just pray your private pictures, banking accounts, and conversations won’t be shared with the wrong people. But the thing is, how can we tell if our devices have been hacked?
In case the smartphone was hacked, it starts showing multiple symptoms that are hard to spot. We may think they are casual and this is just what these technological devices do. But in reality, they may be obvious signs for a possible hijacking.
Please keep in mind that none of the signs mentioned in this article are separated, or absolute. There are, of course, other reasons that cause these devices to act abnormally.
Your device is slower than before
Before you assume that hacking is the reason why your phone or tablet is very slow, make sure none of these following things are occurring:
– Your device updated its operating system.
– You don’t have any more space in your memory.
– You installed bandwidth intensive apps and processor.
If you checked all these three and none of them seem reliable, then there might be a possibility of hacking because when Malware is running in the background, the performance of legitimate apps seems degraded, as well as malware transmissions that slow down the network connection on the phone.
Your Phone is sending or receiving strange texts
In case you noticed that your friends or colleagues complaining about receiving strange messages or emails from you that you never sent, then something must be going on. Likewise, receiving messages directly to your phone that they may be related to a breach is an obvious sign that there is some hacking going on.
When things like this start happening, make sure to change all your passwords and be careful who you give your number to.
New apps are installed – you didn’t install them
If you notice new apps are being installed on your phone and you have no clue where they came from, then do a quick Google research on them to see what reliable tech sites say about them.
However, security vulnerabilities in the operating system that runs Android and iOS may increase their privileges, thus own the ability to circumvent security features, allowing them to record your calls, save your texts and conversations, steal your data, hijack your social media and all your banking accounts.
A sudden increase use of data or text messaging
If you notice that your data or SMS usage is increasing more than expected, especially if it occurred right after some “suspicious” situation, then it could be a sign that malware is transferring data from your device to a different party.
In order to figure out which app is being hijacked, then you can check data usage per each app and see if one of them looks like it is using way too much data than usual.
Moreover, don’t trust installing apps from a third party app store, it is better to do it from a trusted source. But keep in mind, if your device already has malware, then it will not fix the problem.
Your device is attempting to access “bad” sites
To know if your device may be infected, you will find out that it was trying to access sites without your knowledge, even if you were using it on a network that technically blocks access to problematic sites.
On the other hand, you will notice that there are many pop-ups windows, and like computers, there is mobile-device malware that produces these pop-ups! If you have been noticing both these things appearing on your devices, then beware!
Your cell-phone bill is unexpectedly higher
Of course, when you notice that your cell-phone bill is higher than usual, then there might be a chance that criminals exploited your infected device, and probably made overseas phone calls or sent SMS messages to international numbers.
In this case, you can contact your phone agency to check all your incomes and outcomes, and then try to figure out a way to fix this issue with them.
Here are some other reasons you have to be aware of:
– If the battery drains faster than before, then there might be an extra code running in the background.
– For the same reason, your device is hotter than usual.
– Spam filters are suddenly blocking your device’s email.
– If some apps stopped working properly, then it could be a sign of proxying or a different malware interfering with some of the app’s functionality.
– Websites start appearing different than before: Technically, a specific malware is proxying on your smartphone, which sits between the internet and the browser affecting how some sites would display.
– You notice unusual service disruptions. For example, call dropping, strange noises coming through during a call, inability to make a call even when you have good signal strength, etc.
– Of course, data breaches and/or leaks.
What are the solutions?
In case you noticed that your phone is possibly has been hacked, then you should run mobile anti-malware software (it is best if you run more than one), and delete any app you don’t trust or recognize. Also, it is best if you could wipe it all, restore factory settings, and install nothing except from trusted sources.
Obviously, you should start using internet security software on your smartphone or tablet from now on, and if you are worried that malware has been rooted in your device, then show it to a professional.
