One of the most famous security threats on computers are Keyloggers. They are considered as dangerous because it could cause direct damage to your life and is also difficult to detect.
A keylogger can be either a malicious software or a hardware device but both of these have the same purpose. Software-based keyloggers usually come as malware and infect computers through malicious links or downloaded files. These keyloggers silently run in the background without you even knowing that someone is eavesdropping on your keystrokes. Hardware keyloggers are small devices plugged between a computer and a keyboard which can store keystroke logs in their internal memory.
Keylogging malware as the name suggests is a malicious computer program that captures and records your keystrokes which means every word, character and button you press on your keyboard. The keylogger sends a record of your keystrokes to the attacker which may contain your banking logins, credit and debit card details, social media passwords, and much more.
There are different methods to protect your system from a keylogger. Let us take a look at them.
Use a Firewall
In most of the cases, a keylogger has to transmit its information back to the attacker for doing any harm. The data must be sent from your computer through internet. When your internet passes through a firewall there is a chance it will realize something isn’t quite right. But there are chances that it need not detect the issue also. An excellent option is to use The Windows Firewall and there are several other third-party firewall options as well with extensive functionality. A firewall alone might not stop a keylogger but it is better to have one than not.
Install a Password Manager
Keyloggers can’t record what you don’t type. This is when automatic form filling comes to help. Install a password manager which use autofill feature to provide a master password that unlocks a specific account. There are many varieties of password managers available and the popular ones are LastPass and 1Password.
Update Your System
Always keep your system up to date. Updating must include your operating system as well as the applications and programs you run on it. Keyloggers can exploit the outdated software even without your knowledge. New exploits are always discovered by security researchers some of which are not harmful and the others are patched by the developers. Updating software could save you and your system from serious trouble.
Use additional Security Tools
Other than the default security options for Windows 10 and macOS you must consider increasing that security out for maximum protection. Some of the security tools that specifically target keyloggers are Ghostpress, KL-Detector etc.
Change Your Passwords
At any time if you feel something suspicious then use a different computer to change your passwords. It is always advised to frequently change your passwords which will help to minimize the potential damage of a keylogging attack. If you change your password every two weeks, your stolen information will no longer be useful.
All these methods will help protect against keyloggers by reducing the opportunity of infecting your PC with malware. Even though you can never have 100% protection, you can empower yourself and your system in the battle against malware.
