What Is a Keylogger?

A keylogger belongs to the spyware family that tracks you by keys you strike on your keyboard. They work as insidious spyware that watches and records the typed information on a keyboard.

When you type anything on the keyboard, the software sends the log file to some specific server, and the attackers know about it. It means that anything you type gets recorded by the keylogger. It also includes sensitive information like:

  • Credit card and bank account number
  • Confidential messages
  • Social security numbers
  • Username and passwords
  • Website URLs

Keyloggers are both hardware and software, but they are more common as a type of software. The primary objective of a keylogger is to seize the credit card data you enter. They want to steal all your money and other financial data. When cyber-crooks access private information, they make an online transaction to get all the money from the target’s account. Hackers also use them as a spying tool to breach business and government data.

Types of Keyloggers

Based on the nature of the attack, keyloggers of two main types:

Hardware-Based Keyloggers: It is a rare type of keylogger and requires manual insertion to get into the device. As they are hardware so, it isn’t easy to detect them.

Software-Based Keyloggers: These keyloggers are present in the system software. They work in the background without getting noticed. Cyber-criminals install them via phishing emails or other malicious links. They are not always harmful because, at times, companies install them to track their employees. Also, parents install it on the system so they can track their children’s activities. 

How Do Keyloggers Get In Your System?

There are several ways by which a keylogger can get into your system. Like the Trojan horses, a keylogger gets downloaded without your consent. The mentioned below are four ways through which keyloggers infect our system.

Infected System

If your device already has some vulnerability or security flaw, then there’s more chance of a keylogger getting into it. By any backdoor or malicious software, the keyloggers can access your device.

Phishing Emails

Phishing is the most common social engineering method that the majority of the users are not aware of. All the suspicious-looking links and attachments in an email are bogus. Clicking on them exposes your device to a keylogger. Moreover, if in the email the hackers try to trick them into clicking on any malicious link so, the keyloggers soon get activated when you visit the site.

Be wise enough to detect phishing emails and avoid clicking and downloading any unsolicited links and messages. Usually, such stuff contains malware and can infect your system.

Trojan Virus

The cyber-attackers often use Trojans to install keyloggers through fake emails. It looks like legitimate and useful software, but it spreads malware on your device. When you download the software, it infects the system with malware and functions in a way that hackers want them to.

Webpage Script

If you visit any fake and bogus website, then the keyloggers may get into your system. The web page script exploits the browser vulnerability, and the software installs on your device.

Five Ways to Protect Against Keyloggers

The best way to protect against keyloggers is to prevent them from entering your system. But the question is how to protect them? Below are five crucial steps that you can adopt to protect yourself from keyloggers.

Change Your Passwords

Changing your passwords is a good cyber hygiene practice. By changing your passwords weekly or monthly, hackers won’t track you and can’t compromise your valuable data. Even if the hacker compromises your old password, it won’t be of any use because they can’t access your account. Thus, in this way, you can protect yourself from keyloggers.

Also, make sure that the changed password should be strong and complex. The malicious actors can’t break and trace it. And if you find it challenging to decide one such password, use the best password managers.

Update Your System

Always update your system and software from time to time as it protects from malware and keyloggers. The keyloggers often get into your system when they witness any security flaw. Updating the system minimizes such chances and ensures that every loophole gets fixed. 

Install Two-Factor Authentication

It is an extra step for boosting your online privacy and security. Enabling two-factor authentication is the best technique to identify keyloggers. Only those users can access the system or account that passed the two steps verification process. When hackers attempt to access your system without the other verification process, an alert is sent to the real user. 

They can immediately change the passwords and prevent any further damage from happening.

Use An Onscreen Keyboard

Another way to prevent keyloggers from stealing your financial data is to use an onscreen keyboard. It is the best solution for entering your banking details and other sensitive information. Now the majority of the computers have an onscreen keyboard option available. You need to search for it in the program accessories list and start using it soon.

Ending Note.
