What is Keylogger?

Keylogger is a type of hardware device or software program that records all of your keyboard strokes and computer activities, real-time. It sends them to the cybercriminal who installed the Keylogger on your PC.

Cybercriminals use Keyloggers to steal everything from personal information to passwords and financial information.

How Keylogger Works?

So how keylogger works? There are mainly two types of Keyloggers – software and hardware.

The hardware keyloggers are similar to the USB device, which can be easily detected and could be less threat of being tracked anonymously. It is different from software keyloggers, though, because they can be installed easily with the knowledge of the computer user, and continue to capture every keystroke without the user knowing it.

Hardware Keyloggers

Hardware keyloggers are small devices you plug between the computer and the keyboard and listen to the USB (or, for older ones, PS/2) communications between computer and device.

USB Hardware Keyloggers usually look like a USB thumb drive with an extra female USB port on the opposite side. They usually work in a completely passive way; they do not emit anything on the USB bus and tap into the communication line, decode the data from the keyboard and store it in memory.

A more complicated one is a “USB thumb drive” mode where you can download the log as text files, or even include a standalone Wi-Fi interface that connects to a wireless network and sends the log to a preset address (by mail, FTP, etc.).

Software Keyloggers

Software keyloggers do not capture user’s information relying on the presses of the keyboard keys. They have some extra highlights whereby they track the data. That means that any information that the user copies to the clipboard is recorded by keylogging software that has been secretly installed on the machine.

How Keylogger works:

  • So how keylogger works? Keylogger is a small program that runs in the background. It runs without the knowledge of the owner and saves all keystrokes by the keyboard.
  • It sends the log file of keystrokes to a specific email address or a particular server.
  • There is a “master key,” which is used to access the Keylogger, a combination of several keystrokes.
  • When you enter the www.twitter.com in your browser, it’s evident that you will enter the email id and password after that. After that, Keylogger will send those keystrokes to a predefined address.
  • So, someone with basic computer knowledge can quickly get that email id and password.

How Can You Install a Software Keylogger?

It can be installed as software or by sending it in email or sending it as a .jpg file. Cybercriminals can install this software via links or attachment/ files from a phishing mail which the user clicks or opens.

Likewise, web page scripts can also install Keyloggers by exploiting a weak browser. The Keylogger is launched automatically when the user visits the malicious website.

A keylogger can exploit an infected system and is also capable of downloading and installing other malware to the system

Keyloggers are legal. Cybercriminals can use them but they also can be used by employers to track the use of computers by their employees. Tracking their computers will reveal how they spend their work time on the computer. This will bring efficiency in them as they will focus on completing their task rather than spending time on social media.
