Keylogger Definition
A keylogger, short for keystroke logger, is a type of surveillance technology used to monitor and record each keystroke typed on a specific computer’s keyboard. Keyloggers are often used for malicious purposes, such as stealing sensitive information like passwords, credit card numbers, or other personal data. However, they can also be used for legitimate purposes, such as parental control or company security.

What is a Keylogger?
A keylogger is a type of software or hardware that captures every keystroke made by a user on a computer’s keyboard. This can include everything from typed words to login IDs and passwords. The information captured by a keylogger can be used for various purposes, both legitimate and malicious.
Why is a Keylogger used?
Keyloggers are used for a variety of reasons. In a malicious context, they are often used by cybercriminals to steal sensitive information, such as usernames, passwords, credit card details, and other personal data. This information can then be used for identity theft, financial fraud, or other criminal activities.
On the other hand, keyloggers can also be used for legitimate purposes. For example, businesses may use them to monitor employee activity, parents may use them to keep track of their children’s online behavior, and law enforcement agencies may use them in criminal investigations.
Where can a Keylogger be found?
Keyloggers can be found in a variety of places. They can be installed on a computer through malicious software downloads, email attachments, or even physical devices that are plugged into the computer. They can also be embedded in spyware or other types of malware.
When is a Keylogger used?
A keylogger can be used anytime a person wants to monitor or record the keystrokes made on a computer. This could be a parent wanting to monitor their child’s internet usage, an employer wanting to keep track of employee productivity, or a cybercriminal looking to steal sensitive information.
How does a Keylogger work?
A keylogger works by monitoring and recording every keystroke made on a computer’s keyboard. This information is then stored in a log file, which can be accessed by the person who installed the keylogger. Some keyloggers can even send the log files to a specified email address or upload them to a remote server.
Software-based keyloggers are often hidden in other software or files and can be difficult to detect. Hardware-based keyloggers, on the other hand, are physical devices that are plugged into the computer, often between the keyboard and the computer itself. These can be easier to detect, but also easier to install, as they don’t require any software to be downloaded.
