Answer:
The hacker which represents the highest risk to my computer is the Script Kiddie.
Step-by-step explanation:
A Script Kiddie cannot make their own programs.
They hack by using existing codes, scripts, web shells etc to access a work station, mutilate webpages etc.
The difference between a Hacker and a Script Kiddie is that a hacker does not need another person's code. They are skilled at writing their own codes which are can be very potent. This level of skill can be difficult to attain except for very bright minds.
The script kid needs very little knowledge of scripts and they are well on their way to causing damage.
Cheers!
