Types of Malware. The Keyloggeradmin
The keylogger, also known as a keystroke logger, saves whatever the users type on their computer keyboard, for then sending that information to the hacker. Due to it, the cyber pirates can rob username and password, financial data and almost anything you type (for instance, the email content).
The computer keylogger often comes from a worm virus or trojan. The more evolved network keylogger forms are even able to make a computer screenshot. This cancels the effect of an eventual virtual keyboard that it’s used to bypass the traditional keylogger types.
It is also classified as part of the malware families defined as:
- Password stealer.
- Monitoring tools in the Microsoft report.
What is the Keylogger?
It is part of the IT tools that enable to intercept everything that is typed on the computer keyboard, even if it is remote.
Thus, it is a sniffer tool which is used for informatics interception and it may be of two kinds: hardware keylogger and software keylogger.
It was initially designed as methods and devices for legitimate purposes. For instance, to recover password, ID username, non-saved texts, and so on. But with the great diffusion and importance of the computers, in the private and work life, it has become as systems that often damage irredeemably the user privacy, in an illegitimate way.
The Keylogger Types
The hardware keylogger, usually, is a microelectronic cable device, which aspect is like an extension to connect the keyboard cable and the PC. It manages to capture and memorize in some file text all the passwords and other data. For instance, any web address that has been typed on the keyboard.
The software keylogger, instead, is a spy program or “sniffer” that is installed on the computer and it can track and memorize in a log file, hidden from the user, the activities performed on the PC, capturing, for example, a video screenshot, the email messages, the info about the credit cards and so on.
Frequently, the keylogger software is installed without the user knowing about it, through a worm or Trojan virus received through the internet, that remains running on the PC to capture all the typing, such as:
- Sensitive data.
- Credit card numbers.
- User ID, and so on.
All this information is typed, recorded and, then sent to a remote spy computer, which is ready to decode the data and use it.
