Last year, a large-scale spam campaign where attackers distributed a Word document containing a self-executing script programmed to install the Ursnif keylogger software has been detected by security researchers. For example, software keystroke recorder with support for clipboard logging automatically record everything that has been copied to the clipboard, and keyloggers with screen logging support can take screenshots of the entire screen or a specific application, capturing its content as well as the position of the mouse cursor. Most modern software keyloggers offer various related features in addition to the ability to record keystrokes pressed on Windows and Mac computer. One such key logger is even part of the Windows 10 operating system, and its purpose is to send Microsoft information about users’ writing habits and typing patterns to help the company improve typing and writing services. Software keylogger is a computer program that runs on the target computer and record all keystrokes presses.
