In the world of digital era, every keystroke is a danger if you are a target of an attacker. If a hacker has a backdoor to your computer, then nothing can stop him from hacking you. While no defense is perfect, you can still minimize the risks to protect yourself from becoming the target. This post shows how to protect yourself from Key-loggers.
What is a Key-Logger?
Key-Logger is a software or a kind of virus which when installed on a device, records all the keystrokes and sends it to the attacker. These kind of virus/software is installed on target’s device without the victim’s knowledge and the recorded data is sent to the person operating the key logger.
How are Key-Loggers installed?
There could be only two possible ways for an attacker to install a key logger in your system. Either the attacker should have physical access to your computer and he silently installs the software on your computer without your knowledge. Or you yourself invite a key logger to get installed on your system by clicking on malicious links or downloading an untrusted software. There are also chances that key-loggers get installed from web scripts through some web browser’s vulnerability.
Steps to Protect yourself from Key-Loggers :
1. Get a Good Anti-Virus
Install a good Anti-Virus with latest definition updates. If possible, also install a good Anti-Malware for an added layer of protection. The Anti Virus software prevents any unwanted programs to be installed on your system. You can download free trials or get a Paid anti virus for better security. Never install any cracked Anti Virus. Always download trusted software. Don’t click on malicious links or attachments. A Good antivirus also comes with internet protection which helps you browse safely on internet.

2. Use Virtual Keyboard
While entering passwords and sensitive information, use a virtual keyboard. Most of the banking websites also provides virtual keyboards at their login page for security. Virtual Keyboard is a piece of software which allows you to input characters without the actual need of a physical keyboard.
3. Use Password Managers
Remembering lengthy passwords for multiple websites is a difficult task. Password Managers makes it easy for you. The advantage of using a password manager is you don’t have to type your password every time. Some password managers allow you to copy paste and some even auto fill the password fields with the saved passwords.
Unfortunately, password managers and virtual keyboards are not of much use if the key logger uses advanced methods like capturing screenshots.
4. A Good Firewall
When the key-logger records your keystrokes, it eventually sends the data out of your computer to the attacker through internet. If you have a good firewall installed, then it detects any suspicious data going out from your computer.
5. Update your System
Its always a good practice to update your device, whether it be your PC or your mobile. Microsoft regularly releases security patches for any vulnerabilities which may include browser vulnerabilities or any loop holes in your operating system. Your mobile should also be updated whenever a new update is available. It adds an extra layer of security to patch any vulnerabilities.
6. Change Passwords
It is a good habit to change your passwords every 3 months. If you find any suspicious activity in your system or account, then immediately change the password from a different machine.
7. Enable Multi Factor Authentication
Somehow if an attacker gets access to your passwords using your keystrokes, the first thing he does is change the password. At this moment, a multi factor or two factor authentication can save your account. A Multi Factor authentication is a method of confirming a user’s identity using different evidences. For example, an OTP (One Time Password) on your mobile can be a type of authentication in addition to your password. If possible add multi factor authentication to all your important accounts.
