What Is Keylogger?
A key logger 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 key logger recorder can record instant messages, e-mail, and any information you type at any time using your keyboard.
So whenever you enter anything on your computer with the keyboard it will go to the key logger which secretly records everything you type.
For example Usernames, passwords, credit card details email id.
There are two types of key loggers
1.Software key logger
.Spyrix Free Keylogger
.Real Free Keylogger
.Revealer Keylogger Free
2.Physical Key logger
A Physical Key logger
Software Key logger is a secret program which is either installed or hidden inside a pc to record all the key strokes. Whereas the physical key logger is a hardware component which is attached with keyboard or inside the computer hardware system. Hackers install these key loggers in cyber cafes to steal information from the public.
HOW TO PROTECT YOURSELF FROM KEYLOGGERS
Take caution when opening attachments: Keyloggers can be present in files received through email, chats, P2P networks, text messages or even social networks. If someone sends you an email out of the cold or the contents of the email are asking for your personal information, chances are there’s a keylogger in there somewhere.
Implement Two Factor Authentication
Strict implementation of Two-factor authentication through one time passwords would help users protect their sensitive credentials, as the one-time password is momentary and the hackers cannot use the same detected password the next time.
Use of Virtual Keyboard
Virtual Keyboard helps to avoid personal data interception by hackers. It is a software used to allow the users to input characters without the actual need for physical keys.
