If you like auto-completes, grammar checks, parental controls, and plagiarism detection tools, you can thank keyloggers for all the hard work they do for you.
Keystroke logging software, aka keyloggers, do exactly what it says on the tin: they record keys as you strike them on your keyboard.
And while they’re not necessarily malware, they surely turn into one when they monitor your activity and send it to third parties without your consent.
The bad news is that keyloggers are quite hard to discover on Android and iOS phones. The good news is that I’m here to teach you how to do it.
How to spot a keylogger on Android and iOS devices
While ransomware or adware are more the in-your-face type of malware, keyloggers are silent watchers, waiting to snoop on important information like credentials or bank details.
They’re also popular with suspicious partners who’d love nothing more than to see what their half is up to secretly.
But there are some tell-tale signs that your phone has a keylogger.
Your phone gets physically hot
Overheating is usually an indicator that something is wrong with your phone. And keyloggers could be the culprit.
If your phone is still hot even after you’ve closed all the apps running in the background, you can start getting suspicious.
The battery drains quickly
When you use your phone a lot, you develop a sixth sense for how long your battery lasts.
If you notice sudden changes in how often you need a charger, take it as a red flag and investigate matters further.
You hear strange background noises
When they get infected with malware, phones can start acting weirdly.
For example, you might hear crackling sounds or something like a TV running in the background at the end of the line.
However, these sounds can be faint enough to go unnoticed.
You receive strange messages
Malware can mess up the core functions of your phone, so you might start receiving:
-
-
- Messages with just characters,
- Texts that are not supported by your device,
- Messages with weird shortened links.
-
Avoid opening them altogether, or at the very least, do not click on the links.
Your phone acts up
Keyloggers can make you question your sanity because of common behaviors like:
-
-
- Your phone turns on and off randomly,
- Your phone isn’t able to completely shut down,
- The screen lights up randomly,
- Instant messaging apps open randomly.
-
Sure, sometimes all phones seem to have a mind of their own, and overheating and shorter battery lives are common as gadgets get older, but you should pay attention to anything that’s off.
If everything seems OK hardware-wise, you may want to dig deeper and find the issue.
What to do if you find a keylogger on your phone
If you do have enough reason to suspect your device was infected with a keylogger, there are some things you can do.
Check your Downloads folder
Usually, keyloggers are saved locally to monitor your device. They sport inconspicuous names, usually a combination of random characters, with the .APK file extension.
If you find such a file on your phone and don’t remember downloading it, delete it.
Use a good antivirus app
A good antivirus should be able to pick up on the keylogger’s activity and quarantine it. This will protect your phone from further snooping.
It’s also recommended you regularly run scans for malware.
Reset your phone to factory settings
Keyloggers can be challenging to deal with and hard to remove from your device.
If all else fails, you can always resort to wiping everything off on your phone. It’s the most effective way to remove malware and surveillance apps, including keyloggers.
Just make sure you back up any important files beforehand.
Protect your phone from keyloggers
Smartphones are a gateway to your digital life, and cybercriminals are aware of the private information trove you got there.
So, you should do your best to protect your device from digital threats like keyloggers.
Here are six pieces of advice for you:
- Use antivirus software and regularly run malware scans. Take care of all flagged threats as quickly as possible.
- Use a VPN to add an extra layer of encryption to your connection. It will also make you harder to track and target. CyberGhost VPN offers both, a VPN for Android and VPN for iOS phones.
- Avoid free public Wi-Fi networks. They usually lack a secure setup and can expose your traffic to malicious actors.
- Avoid clicking on suspicious links. Phishing scams are running rampant, and they can easily infect your device with malware.
- Protect your device with a password and never leave it unsupervised. It’s child’s play to install a keylogger when you have physical access to an unsecured phone.
- Use two-factor authentication (2FA). This can be your last line of defense in case someone does get their hands on your credentials.
