One of the first things that someone would learn about hacking tutorials when studying to be a hacker is how to cover their tracks. Of course, some are better than others. A young hacker is less likely to know all the little things that an expert hacker might know. Besides, the young hacker may be trying to impress others - and get a little careless about covering his tracks. This is why younger hackers are often caught.
An older hacker, on the other hand, will rarely leave any tracks. They know how to use their victim's computers as a tool for a launching place to get into another computer - leaving a phony IP address.
The truth is, and it is a good thing, that computer programmers are getting better software, and hardware (firewalls) that are constantly doing a better job - both in keeping hackers out, and in recording IP addresses better for tracking purposes.
There will always be hackers, and there will always be hackers in prison. The legislation is definitely turning against the hacker - with some hacking crimes becoming equal to terrorism, these days. Kevin Mitnick, a well-known hacker, had the Federal prosecutors accuse him of having caused $291 million in damages to corporate computers. A serious crime, and he remains in jail because of it - unable to touch anymore computers.
Even by learning some of the wrong type of hacking basics through hacking tutorials, a young person could start down a wrong path. Hacking computers, though often glorified on TV, is still criminal.
