A script kiddie, skript kiddie, skiddie, kiddie, or skid is an unskilled individual who uses scripts or programs developed by others, primarily for malicious purposes.
In a Carnegie Mellon report prepared for the US Department of Defense in 2000, script kiddies are defined as
The more immature but unfortunately often just as dangerous exploiter of security lapses on the Internet. The typical script kiddy uses existing and frequently well known and easy-to-find techniques and programs or scripts to search for and exploit weaknesses in other computers on the Internet—often randomly and with little regard or perhaps even understanding of the potentially harmful consequences.[2]
Script kiddies typically have at least one or more effective and easily downloadable programs capable of breaching computers and networks.[3]
Script kiddies vandalize websites both for the thrill of it and to increase their reputation among their peers.[3] Some more malicious script kiddies have used virus toolkits to create and propagate the Anna Kournikova and Love Bug viruses.[4]
Script kiddies lack, or are only developing, programming skills sufficient to understand the effects and side effects of their actions. As a result, they leave significant traces which lead to their detection, or directly attack companies which have detection and countermeasures already in place, or in some cases, leave automatic crash reporting turned on.[5][6]
Although script kiddie attacks might become increasingly more effective in the future, researchers have noted that other models, like the language model, can also be used to enhance protection against the improved script kiddie attacks. This continuous back and forth improvement suggests that the competition between cyber attackers and defenders will continue to increase.[7]
