A person who uses existing scripts, code, or other tools illicitly to gain entry to a computer system or network, without understanding the way the tools function or the way the system or network is designed.
An amateur who tries to illegally gain access to a computer system using programs (scripts) that others have written. Although they may have some programming skill, script kiddies do not have the experience to write their own programs that exploit vulnerabilities. Malicious code is freely available on the Web (see warez). Script kiddies also tend to be indiscriminate and may try to compromise any computer on the Internet they can reach. See hacker and cracker.
