Hacking is the act of gaining unauthorized access to a computer system, and can include viewing or copying data, or even creating new data. Often hacking is understood to be a way of maliciously disrupting a computer system, copying information, or leaving behind a virus that destroys data.
There are many different reasons why hacking takes place, and these reasons range from wanting to disrupt a system due to ideology (so hacking as a means of protesting); wanting to gain profit for example in order to commit credit card fraud; or simply hacking for the sake of enjoyment and amusement.
There is some controversy about the definition of the word ‘ hacker ’ because those that try to prevent such breaches in security from taking place, or seek to recover lost files, can also be known as hackers. Thus, some people believe that the correct term for malicious system security breaches is in fact ‘ cracking ’ and that ‘ hacking ’ is the correct word to use for those who fight against such malicious exploitation of computer weaknesses.
