What Are the Warning Signs That Your iPhone May Have a Keylogger Installed?

Even though iPhone keylogger malware is often hidden you can still detect it by looking out for these warning signs:

  • Unusual apps – If you spot apps that you can’t remember downloading and have no idea what they are, then this could be evidence of a keylogger.
  • Battery draining faster than use – As keyloggers are constantly running in the background of your iPhone they can radically drain your battery.
  • Frequent crashes – Keyloggers can place significant strain on your iPhone and cause them to crash or freeze.
  • Phone speed decreased – Keyloggers use up memory and can reduce the speed of your device.

If you are serious about detecting iPhone keylogger malware then you should use an antivirus to run a system scan, look out for the Cydia app and keep a close eye on your iPhone’s available space.

Look Out for the Cydia App!

Cydia is an app that is used to jailbreak iPhones. Many keyloggers can only be installed on jailbroken iPhones. So if you spot unusual apps that you don’t remember downloading and Cydia then it is very likely that your iPhone has been compromised and someone has installed a keylogger.

The Cydia app is hidden on iPhones but you can reveal it and check whether it has been installed by opening Safari and navigating to “Cydia://”. 

Please remember that not all keyloggers require your iPhone to be jailbroken to be installed. Therefore the absence of Cydia is not proof that your device is keylogger-free.

To check your iPhone’s free space, follow these steps:

  • Open settings
  • Select General
  • Click iPhone Storage

You will be able to use how much storage your phone has left and how much memory is currently being used. Remember this method only works if you know your iPhone’s free space prior to a potential keylogger infection.
