But when you turn on your computer to start your work, you see a dialog box showing system data is encrypted. And pay given amount to decrypt data.
This kind of dialog is what you will see when your system gets hacked.
This is an example of ransomware attack.
This year in May (2017), a cyber attack raised by a cryptoworm called WannaCry Ransomware targeted Windows OS by encrypting data on the system.

Black hat hackers are those who hack the system to gain unauthorized access to the system and can steal or destroy the data. These type of hackers are illegal and are called crackers.
Gray hat hackers are those who are considered as half black hat and half white hat. They hack the system without permission, find the weakness in the system and then tell the owner about it. They do not hack to harm the system but do it without permission.
Neophyte are those who are new to hacking and may have some or no knowledge about hacking. They are sometimes called Green Hat hackers.
Script kiddies are those who have very less knowledge and are considered non-skilled. They do not care much about how they hack. They use tools which are made by some other person for hacking.
