hardware keylogger and how it works

In this post, I am going you to tell about hardware keylogger and how it works on a computer to access user information and data. How to prevent from a keylogger? Before that, we discuss what is keylogger?


A keylogger is a type of surveillance software (considered to be either software or spyware) that has the capability to record every keystroke you make to a log file, usually encrypted. A keylogger recorder can record instant messages, e-mail, and any information you type at any time using your keyboard. The log file created by the keylogger can then be sent to a specified receiver. Some keylogger programs will also record any e-mail addresses you use and Website URL you visit.
Keyloggers, as a surveillance tool, are often used by employers to ensure employees use work computers for business purposes only. Unfortunately, keyloggers can also be embedded in spyware allowing your information to be transmitted to an unknown third party.

Hardware Keylogger

A Hardware Keylogger is nothing but a programmed chip (Mostly in Assembly Language), so as to capture all the keystrokes, information and save them in its internal memory. The keylogger can then be taken out and all the stored information can easily be assessed by the hacker. This is most commonly used in cyber cafes and other public places where a lot of people come and access the internet. Beware of such places.

Always check the keyboard connectors before accessing the internet at such places. It is extremely powerful and effective and if they are actually installed on any machine and you use it, there is almost 90%+ chance of you getting hacked.

How it works 

Imagine you going to a cyber cafe and make a bank transaction just to pay your bills. When you enter your login detail, the hardware keylogger will save your all details and that can be used for any transaction purpose anytime. Some advance hardware keyloggers might also take screenshots at regular interval so that the hacker knows the login details are for which website or web page.


To secure yourself from such attack, there is only one way. Check the hardware of the computer you use at public places and even your personal computer if your friends come to your place often. Who knows who might attach the hardware keylogger in your machine. so beware of this type of attacks and security and share this with your friends to make all aware of this kind of activities.
