Keylogger

A keylogger (sometimes referred to as a keystroke logger or keyboard logger) is a type of software application specifically designed to record all keyboard entries by the user of a computer. It is usually used to record keystrokes without the user being aware, and it is often used to capture passwords and other confidential information.

Keyloggers can be either hardware or software based. The most common type is the software version, which records and logs the keystrokes that have been typed onto a computer keyboard. This type of keylogger is typically installed onto the computer by someone with access to the computer, either by physical access or by remote access, and is invisible to the user.

Hardware keyloggers, also known as “hardware keystroke recorders,” are a form of keylogger which are physically installed between the user and keyboard. These can be connected to the PC via a USB cable or placed inside the PC or laptop. They are often used to record data which is entered by the user, such as passwords and other confidential data.

Keyloggers can be used for both legitimate and malicious purposes. Legitimate uses may include monitoring employees’ use of company systems and checking for computer misuse, as well as ensuring that only authorized users gain access to sensitive data. Keyloggers can also be used for malicious purposes, such as stealing passwords and confidential data, or monitoring a person’s online activities.

Keyloggers are a serious threat to the security of both individuals and businesses, as they can be used to gain access to confidential data and personal information. It is important to ensure that a strong anti-malware protection is in place to protect against keyloggers, as well as regularly monitoring the computers for any suspicious activity.
