Hacker?

I was mentioned about hackers in old posts about online game 2Moons. Well, some ask me why are they called hacker? well, actually the term 'hacker' can be applied into many fields. For me, those who specializing in the discovery of exploits in systems are called hacker, no matter in which fields they are working at.

The term "Hacker" may mean simply a person with mastery of computers; however the mass media most often uses "Hacker" as synonymous with a (usually criminal) computer intruder. See hacker, and Hacker definition controversy. In computer security, several subgroups with different attitudes and aims use different terms to demarcate themselves from each other, or try to exclude some specific group with which they do not agree.

They are many types of hackers actually, Wanna to know more about hacker's attitudes?

White hat
A white hat hacker or ethical hacker is someone who breaks security but who does so for altruistic or at least non-malicious reasons. White hats generally have a clearly defined code of ethics, and will often attempt to work with a manufacturer or owner to improve discovered security weaknesses, although many reserve the implicit or explicit threat of public disclosure after a "reasonable" time as a prod to ensure timely response from a corporate entity. The term is also used to describe hackers who work to deliberately design and code more secure systems. To white hats, the darker the hat, the more the ethics of the activity can be considered dubious. Conversely, black hats may claim the lighter the hat, the more the ethics of the activity are lost.

Grey hat
A grey hat hacker is a hacker of ambiguous ethics and/or borderline legality, often frankly admitted.

Blue Hat
A blue hat hacker is someone outside computer security consulting firms that are used to bug test a system prior to its launch, looking for exploits so they can be closed. Microsoft also uses the term BlueHat to represent a series of security briefing events.

Black Hat
A black hat hacker is someone who subverts(To destroy completely) computer security without authorization or who uses technology (usually a computer or the Internet) for terrorism, vandalism(malicious destruction), credit card fraud, identity theft, intellectual property theft, or many other types of crime. This can mean taking control of a remote computer through a network, or software cracking.
