Have your accounts been getting hacked recently? Has your iPhone been acting weird? Then your device may be infected with a keylogger. 

A keylogger is a piece of malicious software that records all of your keystrokes and then sends them to a nefarious 3rd party. With a keylogger, a hacker can access your passwords, sent messages, sent emails, confidential notes, and more!

In this article, we are going to explore how to check iPhone for keylogger and how to get rid of keylogger on iPhone. We are going to help you quickly protect your device and prevent hackers from getting access to your accounts!

How Do Keyloggers Work?

Once a keylogger is activated, it will start recording all of your keystrokes. It then saves this data into a file and then, via the internet, secretly sends it to a 3rd party. Keyloggers can be programmed to quickly identify passwords. For example, the keylogger may highlight all of your keystrokes after you type “@” because you often have to enter your email and then password to sign into your different accounts.

Hackers have come up with a number of different ways to install keyloggers on iPhone. The most common methods include the following:

  • Phishing. It is the act of sending fraudulent messages. The goal of these messages is to get you to click on a link that downloads a keylogger or a file infected with keylogger software. For example, you may get an email that looks like it comes from Amazon, explaining there is something wrong with your account and telling you to click on a link to fix the issue, and when you do, it triggers an automatic download.

  • Webpage scripts. Hackers are able to insert code into a website which triggers the download of a keylogger as soon as you open the website. 
  • Hidden in legitimate apps. That new app you just downloaded could have a keylogger buried inside it. While Apple does a good job of preventing malicious apps from appearing in the App Store, they don’t catch 100% of them.
  • Physically accessing your phone. This method involves a hacker literally taking your device when you are not looking and installing the keylogger app for iPhone. These apps can be set up in under 5 minutes, so you are vulnerable even if you are briefly separated from your phone. 

There are two main types of keyloggers, hardware, and software. For a hardware keylogger to work, it needs to be physically connected to your device. In the case of an iPhone, this needs to be done via Apple’s proprietary Lightning port connector. Hardware keyloggers aren’t used on phones because they are so conspicuous but can be secretly installed on computers or phones. Read our guide about how to find hidden apps on iPhone.

Software keyloggers are a significant threat to iPhone users because you can accidentally download them by downloading a piece of software, going to the wrong website, or clicking a seemingly harmless link. Also, once installed, you often won’t be able to tell as your device will run like normal, and there will be no app on your home screen. There are many spy apps for iPhone that can be used as a keylogger, by the way. For example, mSpy: pay attention, that this app allows to monitor every keystroke.

How to Find Keylogger on iPhone?

To find a keylogger on iPhone, you need to look out for common warning signs such as frequent app crashes, your device turning on and off, overheating, slow performance, increased data usage, and your battery wearing out quickly.

  • App crashes. Did your favorite apps start crashing out of nowhere? If you have sufficient spare data, then this is a sign your device may be infected.
  • iPhone turning on by itself. If your battery is fine, your phone is not physically damaged, and it is not overheated, then the cause of your phone turning off is likely some sort of malicious app like a keylogger or other spyware.
  • Overheating. It is not uncommon for iPhones to overheat. However, if there is no change to your device usage and suddenly it starts overheating, then a keylogger could be the cause. 
  • Slow performance. Keyloggers can really slow down your phone and cause it to freeze and crash. If there is no reason why your phone should be running slow, then some kind of nasty app is likely the culprit.
  • Increased data usage. Is your data spiking out of nowhere? Are you struggling to identify the source of these data spikes? Then your device may be infected.

You should not ignore the above warning signs. If your phone even has one of the above symptoms, you may be dealing with an iPhone keylogger

Check for Slow Performance

To ensure your phone’s slow performance is not caused by other factors, you should:

  • Turn off Low Power Mode. Go to Settings>Battery and toggle off Low Power Mode.
  • Check your battery’s health. Go to Settings>Battery and read the different insights provided by Apple.
  • Make sure your iPhone is not overheated from hot weather. Overheated iPhones are known for running slow.
  • Check your iPhone has sufficient storage. Go to Settings > General > [Device] Storage. If your iPhone is running low on storage, it will be running slow.
  • Close all apps. Go to the home screen and swipe up from the bottom, then swipe up on an opened app. Having too many apps can often slow down your phone.
