Telltale signs an app is violating your privacy
Authored by a Symantec employee
Malware isn’t just for laptops and desktops. In fact, it can be a lot easier for malware to end up on your mobile phone or tablet than your computer. When it comes to mobile malware, a little bit of paranoia goes a long way. Malicious apps can steal your personal information, including sensitive financial information that can then be used to steal your identity. A lot of malware ends up on your phone due to malicious apps. So what are signs that you might already have a malicious app on your phone?

Slow Internet Connections
A slow Internet connection doesn’t always mean malware, but it is one of the few symptoms that even the most sophisticated malware can’t hide. Whether a malicious app is phoning home, communicating information about you or using your mobile device as part of a botnet scheme, it’s going to be using Internet bandwidth to do it. So if your connection speeds are all of a sudden crashing down to nothing, that can be a very clear sign that there’s something amiss with one of your apps.
Large, Unexplained Charges
On the same token, one giveaway that you have a malicious app is that your phone bills are way bigger than what they ought to be. Massive phone bills can result from a malicious app that’s a data hog or a malicious app that’s sending lots of premium text messages, then sticking you with the bill. There are few surer signs that you’ve become a victim of a malicious app than by getting an astronomical phone bill with your name on it. If this happens, call up your phone company and start thinking seriously about which one of your apps is the culprit.
Using Too Much Data
Even if you don’t have huge charges, you want to keep an eye on your overall data usage. For example, you might have an unlimited data plan. In this case, a bill might not tell you much about what a malicious app is doing to your phone. You’d have to actually check the data usage to see if you had become a victim of a malicious app. Keep an eye on your data plan. Look for spikes in data usage. Again, this is one of the ways that even some of the most low-key malicious apps can give themselves away. There’s just no way to hide the use of data.
Your Battery Life Is Bad
Generally, you get a good idea of how much battery life to expect out of your phone. While it might vary by how vigorously the phone is being used, you’ll notice a decline in battery life if you’re the victim of a malicious app. Much like data usage, this is one area that even a sophisticated malicious app can’t conceal. The processes the malicious app is running require battery power and there’s no way around that. The battery life decline won’t be subtle or easy to ignore. One day, you’re getting by on a full charge all day, the next your phone’s battery is draining so quickly you have to charge it almost all day.
Phone Connections Frequently Drop
Dropped calls and other problems with your calling service can also be a sign that you have a malicious app. Much like with battery life, the key here is seeing differences. You might never get reception in one place, so if you continue to have dropped calls in areas with poor reception, that probably doesn’t mean anything. On the other hand, if you generally get crystal clear reception at home and then all of a sudden you’re not, a malicious app could be the culprit.
How to Stay Safe:
Malicious apps can be a real headache. Not only can they slow your phone’s performance, they can also lead to identity theft and financial troubles.
Still, you can avoid getting them in the first place without much effort:
- Install an Internet security suite on your phones and tablets such as Norton Security.
- Don’t click links or download files from people you don’t know and never scan QR codes.
- Always update your mobile apps and operating system as soon as possible. Lots of malicious apps are just ways of exploiting existing problems in your software. Updates patch these problems so that hackers have to find a new way in.
- Only download apps from the official app store for your operating system. These apps tend t be heavily vetted, whereas apps being sold on third-party sites can be made by anyone.
Keeping your phone free of malicious apps isn’t that hard. It just requires a bit of due diligence and common sense on your part.
