There is no doubt that there are many hackers out there.
Traditionally, some (black hat) hackers are worse than the others. These hackers are professionals, sponsored, and have both the knowledge and experience of a malicious coder working in the dark.
Other kind of hackers, are more like "script kiddies", newbies, wannabes or who simply follow the former.
But with the internet growing, knowledge can come easier than ever before.
Since experience can never come easy, professional hackers can share their knowledge, and tools, in exchange for money.
