DESCRIPTION
A rootkit is a piece of software, usually a small application or code whose main purpose is to conceal itself from the user or other applications. Originally rootkits were created to both obtain root or superuser privilege on a computer system as well as hide elements such as processes, files, and network connections. With the advent of spyware, rootkits have been designed to hide the aforementioned elements with the specific intent of remaining resident while capturing personal and personally identifiable data or performing other nefarious activities.
