Kevin was a Malicious Hacker =

The term hacker is ther term adopted by the media in general and by the hackers themselves. I am entirely familliar with the MIT use of the term, I worked at MIT. It is unfortunate that the crackers have appropriated this term but they have been successful in doing so. Attempting to redefine the term at this stage is futile.

If you want to refine the term, point out that Kevin was frequently vindictive and malicious. He is also pretty unrepentant, he still whines about the length of the prison term he got, I don't think it was enough. Kevin is still a hussler, its just that his latest scam, security consulting is at least legal even if it is difficult to see how any client could trust him.
