Keylogger – The Surveillance Tool (2022)

If you have searched about keyloggers and want to learn about them then you are at the right place in this article, you will know about keyloggers and know the use of a Software keylogger with a demo practical using the KidLogger tool.

What is a keylogger?


A keylogger is a spyware tool used to monitor the keystrokes from the keyboard that the user inputs into his system. This tool is mainly used by cybercriminals to steal login credentials or important sensitive data. It can work on desktops, android, and ios also.

At first, the keylogger was made to do good work such as monitoring the criminals and taking preventive measures against them but it slowly came into the hands of the wrong people who used it for their advantage like stealing login credentials and taking advantage of it.

Types of Keyloggers

These are mainly of two types-

  • Hardware
  • Software

Hardware Keyloggers:


Hardware keyloggers are implemented via BIOS-level firmware, or alternatively, via a device plugged inline between a computer keyboard and a computer. They log all keyboard activity to their internal memory.

It has a microcontroller that interprets the data stream between the keyboard and computer, processes it, and passes it to the non-volatile memory and a non-volatile memory device, which is a flash memory that stores the recorded data, retaining it even when power is lost.

Hardware keylogger cannot be identified by any antivirus software it can be only identified physically.

Software Keyloggers:

Software Keyloggers are implemented by installing the software into the victim device passively and it doesn’t require any type of physical involvement. It stores the record of the keystrokes in a log file and sends it to the attacker via email.

It can be identified by antivirus software and by other means of software.

For a demo purpose, I will open notepad and start typing something so that I can show you the log files that how the software monitors. After that, you can stop monitoring or directly click on the view current log option from the software to view what the software has monitored.

Alternatively, you can go to the location where you have desired to save the log, by default it is in C:\Program Files (x86)\KidLogger\logs\. from there select the HTML file to view the output.
