How To Tell If Your Smartphone Has Been Hacked

It takes a bit of effort, but iPhones can wind up with viruses and malware. And that can indeed lead to all kinds of snooping.

Whether through malware or a bad app, hackers can skim personal info while you browse, bank, and shop. They can also infect your phone with ransomware that locks up your personal info or that locks up the phone itself.

Those are some worst-case scenarios. However, good for you and unfortunate hackers is the way iPhones run apps. It makes it tough for viruses and malware to get a toehold. Apple designed the iOS operating system to run apps in what's called a "virtual environment." This limits the access apps have to other apps, which helps prevent viruses and malware from spreading.

Still, malware can end up on an iPhone in a couple of ways:

The owner "jailbreaks" the iPhone

This practice gives people more control over their iPhones. By jailbreaking, they gain "root control" of the phone. With that, they can do things like remove pre-installed apps and download third-party apps from places other than the App Store. And that's where the trouble can start.

Jailbreaking removes several of those barriers that keep viruses and malware from spreading. Further, downloading apps outside of the App Store exposes the phone to viruses and malware. Apple doesn't review the apps in those stores. That way, a hacker with malicious intent can post a bad app with relative ease.

A malicious app sneaks into the App Store

Apple has a strict review policy before apps are approved for posting in the App Store. Per Apple, "Apple's App Review team of over 500 experts evaluates every single app submission - from developers around the world - before any app ever reaches users. On average, the team reviews approximately 132,500 apps a week."

However, bad actors find ways to sneak malware into the store. Sometimes they upload an app that's initially innocent and then push malware to users as part of an update. Other times, they'll embed malicious code such that it only triggers after it's run in certain countries. They will also encrypt malicious code in the app that they submit, which can make it difficult for reviewers to sniff out.  

So, barring a jailbroken phone, the chances of getting a virus or malware on your iPhone remain low. Still, it can happen.

How to know if your smartphone has been hacked

Because we spend so much time on our phones, it's fairly easy to tell when something isn't working quite like it is supposed to. While you can chalk up some strange behavior to technical issues, sometimes those issues are symptoms of an infection. Malware can eat up system resources or conflict with other apps on your phone, causing it to act in odd ways. 

Some possible signs that your device has been hacked include: 

Performance issues 

A slower device, webpages taking way too long to load, or a battery that never keeps a charge are all things that can be attributed to a device reaching its retirement. However, these things might also be signs that malware has compromised your phone. 

Your phone feels like it's running hot

Malware running in the background of a device might burn extra computing power, causing your phone to feel hot and overheated. If your device is quick to heat up, it might be due to malicious activity. 

Mysterious calls, texts, or apps appear

If apps you haven't downloaded suddenly appear on your screen, or if outgoing calls you don't remember making pop up on your phone bill, that is a definite red flag and a potential sign that your device has been hacked. 

Changes or pop-ups crowd your screen 

Malware might also be the cause of odd or frequent pop-ups, as well as changes made to your home screen. If you are getting an influx of spammy ads or your app organization is suddenly out of order, there is a big possibility that your phone has been hacked. 

Three tips to prevent your phone from being hacked

To avoid the hassle of having a hacked phone in the first place, here are some tips that can help. 

1. Update your phone and its apps.

Promptly updating your phone and apps is a primary way to keep your device safer. Updates often fix bugs and vulnerabilities that hackers rely on to download malware for their attacks. 

1. Avoid downloading from third-party app stores.

Apple's App Store has those protections in place that we mentioned before. That's unlike those third-party sites, which might not have those same protections. Further, some purposely host malicious apps. Avoiding these sites altogether can prevent these apps from allowing hackers into your device. 

1. Don't use a jailbroken phone.

As we've seen, jailbreaking a phone introduces all kinds of security issues. Your best bet as an everyday internet user is to rely on iOS and the protections that come with it.
