Just got hacked by Netbeans xD

[greenpk2]

I find it both funny and serious. I know so little about PHP, MySQL & HTML.
I know some basic codes and the setup, but I am not advanced. I knew this would happend anyway, because we don't got the best webhosting service. This website is used for a private server, but the server is soon opening. I am thinking about let it go for a while, but elitecarders if you know how to secure us better I would be happy to get some information from you. I also read some articles how they hack and how to secure, but some of it are too advanced to me, since I am still learning the basics

I can tell one thing for sure, he just changed the content of the page... Maybe he is haunting us, because he wants me to mail him. If I think logic it might not be smart + he might demand cash... xD
