How To Detect the Presence of a Keylogger on Your Phone

Keyloggers: How They Work and How To Detect Them

A keylogger records the keystrokes you make while using your device. This information is then passed to a hacker by way of a command-and-control (C&C) center. Using the data collected by the keylogger, the hacker can figure out your username and password for various online accounts. This makes keyloggers a significant cybersecurity threat, possibly as dangerous as ransomware and other malware.

You can typically detect a keylogger by observing the performance of your phone or whether someone else is trying to log in to one or some of your accounts.

How To Know if a Keylogger is Installed?

If a keylogger is installed, you may notice some or all of the following:

  1. Your phone is using an excessive amount of data—even when you are not actively using it. This could be because hidden tools are running in the background and processing data from the internet.
  2. Your phone freezes up a lot. Because keylogger software reads apps, it can cause them to run poorly or get hung up.
  3. The battery gets hot—even when you are not using your phone. The reason for this is the keylogger is running in the background, taxing your battery.
  4. You can hear background noise while using the phone.

Use Two-factor Authentication

To detect a keylogger in iOS, you can use 2FA, which requires a second form of identification, in addition to a name and password, when accessing an account. Whenever a hacker who has stolen your credentials via a keylogger tries to log in to an account, with 2FA, you will get a notification through the second authentication method, such as a passcode sent to your phone, for example.

How To Remove Spyware from IOS

After you detect a keylogger in your phone, you will want to remove this kind of spyware, which essentially executes a phishing strategy without ever engaging you, the user. Phishing is used to steal login credentials and to install malicious software, such as Agent Tesla, which is a keylogger that attacks Windows machines. To get rid of spyware, you should first change your login details. This can prevent someone with your login information from getting into accounts that have the same details.
