Answer:
The term used in relation to a person who writes computer codes, and programs to hack into another person´s computer as an amateur, and therefore uses the work done by others, instead of his own, is known as a Script kiddie, a skiddie, or skid. So this teenager in the question would be known as such.
Step-by-step explanation:
There is a culture of hackers who dedicate themselves to creating programs to hack into people´s computers through codes and programs. When these hackers become tenured, they are able to develop their own codes and programs and cause a lot of damage. However, when someone is just starting up in the culture, this person tends to use the programs developed by others to hack into computers. These amateurs, whose work is not created by them, are known in hacking culture as skiddies, scrip kiddies, or skids. As they mature, they become capable of developing these programs all by themselves.
