In computing, a script kiddie (occasionally script bunny, script kitty, script kiddo, "skidiot", skiddie or Victor Skill Deficiency (VSD) and even lamer) is a derogatory term for inexperienced hackers who use scripts and programs developed by others, without knowing what they are or how they work, for the purpose of compromising computer accounts and files, and for launching attacks on whole computer systems (see DoS). In general, they do not have the ability to write these kinds of programs on their own. Such programs have included WinNuke applications, Back Orifice, NetBus, Sub7, and Metasploit.
