What Is A Keylogger | Step By Step Guide

What is a keylogger

What is a keylogger?

Keyloggers are also known as keystroke loggers. They start immediately after the start of the operating system. The keylogger records every keystroke of any key or only those that will be made in certain fields on sites.


Keyloggers can be integrated into the operating system of a computer. This type of malware is called rootkits. There are keyloggers that can work at a lower level. For example, it can be added to the browser as a hidden extension.

There are many scenarios for keyloggers. It is especially difficult to counteract the rootkit. Antivirus programs usually cannot reach this level, and therefore such keyloggers continue to work without any interference.

In other words, we can say that keylogger (KL) is a tool designed to record all keystrokes on a computer, through software or a hardware device. This recording activity from the keyboard is also called keylogging or keystroke logging.

Keylogger Definition

A keylogger is any component of software or equipment that can intercept and record all manipulations with a computer keyboard. 

Often, a keylogger is located between the keyboard and the operating system and intercepts all user actions. This tool either stores the intercepted information on the infected computer or, if it is part of a larger attack, all data is immediately transferred to the remote computer of the attack organizers. 

Although the term "keylogger" is usually called malware, sometimes it is also used by law enforcement agencies.

Positive use of keylogger

Despite the fact that they are used for illegal activities, keyloggers have several positive options for exploitation. 

If it is used with good intentions, it can help parents monitor their children's activities on a PC or be used by an employer to determine how their employees use their PCs during the work period. 

However, it should be noted that this should only be done with the voluntary consent of the staff. 

A keylogger can also be used to protect (write) passwords and other data in the event of an operating system failure (but there are certainly better ways to do this). In addition, keystroke logging was recently adopted by scientists as a tool for studying the processes of human writing.

Negative use of keylogger

As the name implies, the purpose of the keylogger is to record each keystroke from the target computer, which is not always bad. 

But unfortunately, the most common use of a keylogger is related to malicious activity. 

Keylogger programs are widely used by cybercriminals as a way to steal confidential information from victims, such as credit card numbers, passwords, personal letters, bank credentials, driver’s license numbers, etc.

Types of keylogger


As mentioned earlier, there are two main types of keylogging devices. There are a software and hardware version. When it comes to software and hardware keyloggers, it is important to understand the differences between the two types. 

Although the most common is the software version, you should understand how the hardware Keylogger works.

Hardware Keylogger

1. It usually consists of a small chip or wire that is physically attached to a computer or laptop.

2. Most hardware Keyloggers can be easily removed.


3. The extracted information can be viewed using a coordinating computer program, even after removing the chip or wire.


4. It is usually the preferred type of keylogger for companies that care about their employees.


5. The uniqueness of software keyloggers is the KL firmware version, which can be connected to the computer BIOS and write data as soon as it turns on.


6. Keylogger wireless sniffers are capable of intercepting communications between wireless keyboards and a computer.

Software Keylogger


Unfortunately, a software keylogger is much harder to detect. There are many different categories, with different methods and technologies, but in general, we can consider the following:

1. It usually consists of software that was secretly installed by a hacker on your computer. You can download directly to the host computer (for example, using phishing attacks), or remotely.

2. The most common software keyloggers record only the activity of the computer keyboard, but there are modified versions that can take screenshots and clipboard logging.

3. Less common types of software Keylogger include those that are based on Javascript (entered on websites), APIs (running within the application), and web forms (recording any data presented in web forms).


Hardware keylogger prevention

It is very unlikely that you may have a hardware keylogger, especially in the privacy of your own home. 

However, this is possible in a public environment. Since the USB port is usually used for the hardware keylogger, your main protection will be to use random checks in the USB area of ​​your computer.


When entering confidential information such as a password, you can also use the mouse to confuse the keylogger, if any. For example, first, enter the last character of your password, and then move the cursor to enter the rest. 

The keylogger will register the last character as the first. Selecting and replacing text during input is also an option. You can try many different ways or other methods to trick tipping. However, these methods are not very functional, and may not work with more complex keyloggers, which also record the screen or mouse activity.

Implement two-factor authentication. Two-factor authentication is the best way to protect yourself from keyloggers because if the attacker knows your password then also he will not be able to log in.

Use the virtual keyboard. Use the virtual keyboard if you use virtual keyboard then keylogger will not be able to record your strokes.


Software keylogger prevention

Software keyloggers are more difficult to detect, but installing a good antivirus will most likely help you to be safe.

Installing an anti-keylogger software is also an option, as it is specifically designed to detect, remove, and prevent keylogger attacks.

Be careful with email attachments and links. Do not click on ads or sites from an unknown source.

Update your software applications and operating system


Any user who uses Internet banking or any other online activity that is related to money should be especially careful (including adherents of cryptocurrencies and traders).

method of implementing two-factor authentication and the use of a virtual keyboard applies to the software keyboard also.

But nowadays some keylogger has the capability to record the virtual keyboard too.


How keyloggers spread?

  • When the user visits the malicious website keylogger can be installed through a malicious webpage script.
  • A keylogger can be installed if the user opens a malicious file attached to an email.
  • A keylogger can be installed if the user opens any unwanted malicious file given by hackers by social engineering.
  • A keylogger can be installed if you download any software from the unwanted website. Because many hackers bind keyloggers in the software.

How hackers install a Keylogger?

Hackers can install keyloggers in your system through many steps. Hackers can send you an email by attaching a malicious file in it. As you click on the email and open the file the keylogger will get installed without your information.

Another method is to install a keylogger through the website. Hacker can create a malicious website and send to you by social engineering technique. As you click on the website malicious JavaScript will run and if you click allow on the website page the keylogger will get downloaded.

Another method is to bind a keylogger in software. For example, hackers will bind a keylogger in the UC browser and send UC browser app to you as you install the browser keylogger will get activated in your system.


How to detect Keylogger

The easiest way to detect keylogger software is to open the task manager and check the running processes. 

Many of the background processes have strange names. If there is something that looks strange, you should look it up on the Internet and try to find out if it is a legal program or a well-known keylogger. 

In addition, it is also important to examine your outgoing traffic from your computer.

How to remove keylogger

A comprehensive anti-keylogger should check all processes running on your computer: BIOS, operating system, background services. As well as network settings, plugins and browser settings.

To get rid of the keylogger, you may have to reinstall the operating system.

Keyloggers can be legal and illegal depending on the way you use them. Suppose if you are using keyloggers for activities such as stealing user data and personal details or bank account details then keyloggers are illegal.

Keyloggers are legal if you are using the software for parental control (monitoring your kid's activities) or employee monitoring.  But keep in mind that you must have administrator rights to install the keylogging program on someone else’s device.

Many employers install keyloggers to monitor the activities of their employees at work. Monitoring software can help reduce time loss and increase employee productivity. 

Keyloggers can also be very useful when you need to protect your corporate data and collect evidence for the legal protection of your company.

In addition, keyloggers are very useful when it comes to monitoring children. Good monitoring software can solve many problems at a time: you protect your children from watching porn at a small age, you can manage their time and block unwanted websites. 

Keyloggers are often used by parents who want to make sure their children are safe on the Internet, as there are many predators on the Internet. In addition, they can be used to study the interaction of a person with a computer.
