Hacking

Hi, do you need very highskills like programming to hack some smaller sites for example?

I have no idea how to do it at all.

Are there some manuals for beginners? What tools do you need for?

Or better just demonstrating pages, where you can test you hacking skills (of course for very beginners;) ?

#9 true^^

But aren't there example servers/sites which are designed to test the skill of oneself.
So somehow like see if you can intrude the system etc.

Something like that must exists for beginners too, or?
