How to detect hidden keyloggers on smartphones

Smartphone keyloggers can be a major threat to your personal information. If you frequently use your phone to access important accounts like your bank, send sensitive messages, or even unlock your home door, a keylogger can secretly steal all that information without you even knowing it.

Keyloggers can also hide on mobile phones

Therefore, it is necessary to equip yourself with knowledge to detect and prevent keylogger threats.

Keylogger Definition

A keylogger is a type of software or hardware device that is designed to silently record every keystroke on a computer or mobile device. The main purpose of a keylogger is to collect sensitive information such as passwords, bank accounts, credit card information, and other personal data.

Cybercriminals often use keyloggers to carry out attacks to steal personal information and accounts. It can be deployed through malicious emails, phishing websites, or other means to lure users and install on the victim's device.

How to identify hidden keyloggers on smartphones

Keyloggers are more difficult to detect than other types of malware. But there are some telltale signs to look out for.

1. One of the most obvious signs of a keylogger is a delay when typing on the keyboard. This is because the input information entered on the keyboard will take time to be processed and recorded by the keylogger.
2. Next, your device's performance will suffer significantly. Slow response times, app crashes, and graphics that don't load smoothly are also signs to watch out for. These are because your phone is processing more processes than usual.
3. Overheating is another symptom of a keylogger on your phone, as they often actively work in the background. It is worrying if your phone is unusually hot without any apps open. It is also worrying if your battery is draining faster or your mobile data is consuming abnormally.

If you notice any of these signs, restart your phone. If the problem persists, your device may be infected with a keylogger. If you have an Android device, use Google Play Protect to scan your entire phone.

Apple devices don't have built-in security features (mostly because iOS is less susceptible to malware than Android), but you can download a trusted third-party security app like Avast or Norton 360 to scan your system.

It's important to note, however, that iOS devices aren't completely immune to malware, like ransomware and keyloggers, as many devices can still be hacked through jailbreaking or targeted by hackers with advanced forms of malware like Pegasus.

How to remove keylogger from phone

Once you have determined that a keylogger is present on your phone, you have a few options for removing it. The easiest way is to run a malware scan using a security app. If the scan detects a keylogger, the app will ask you to delete it. Do this and restart your phone.

Another way is to manually search for and remove suspicious apps. Any app that is not downloaded from an official app store should be checked. The same goes for apps that cause performance degradation after installation.

If neither of these methods work, try a factory reset. There are multiple ways to perform a factory reset on Android or iPhone, but you’ll need to back up any important data before doing so. Restoring your device will erase any unwanted data, including the keylogger.
