Comment nr.1: Hacking is exploring the limits of what is possible, thereby doing something exciting and meaningful. Comment nr.2: Interesting way to put it Comment nr.3: Hacking is fun , until u ruins somebody life its become crime . If you are a white hat hacker there is no way for you to ruin somebody's life. Black hat hackers, however, use hacking to their advantage and abuse it in every way possible.Groups like Anonymous are on the line between white hat and black hat: their goals are concidered white hat as they are simply trying to prove a point, yet they cause millions of dollars in destruction to servers etc which makes them black hat hackers. Anonymous is/are formed groups of like minded individuals to succeed in common goals or missions, similarly to activists, protesters, or a voice. Not a real group and has no actual leadership. Which is rather different than just hacking as it involves much more than just IT if even at all. Even though the majority of Anonymous' goals being birthed from internet based media outlets like ***** and other ideals. The 414s would be better example of a mixed hat hacker group who really did no malicious harm. Due to the legality of methods deployed by Anonymous to prove their points, they are perceived and labeled as Black Hat. Regardless of them expressing internet activities as a freedom of protest, they are done so of the majority with malicious intents (DDoS).There is however a classification for Grey Hat hackers, to which fall somewhere between purely altruistic (White) and purely malicious (Black) very much so like the 414s. For example a Grey Hat may find an exploit but not use it illegally and not divulge it to others. White Hats are usually employed as "penetration testers" to find/fix exploits and test security. Black Hats will attempt to use and share an exploit for personal gain or malicious use of some form. Whereas Grey Hats are usually wanting to learn how the system works and what they can make it do. For example allowing me to bypass a two-step authentication requirement to access my own account, but not use or share those methods to gain access to others. I am interested what these guys do all day, and if they help others and if they are among us on BlackHatworld.
