Hackers

Hackers are the people who use the digital media to break in (hack) personal computer or servers via the network. Usually hackers do what they do to steal information but that not the only reason hacker exist.

there are many types of hackers :

White Hat: A white hat hacker is someone who has non-malicious intent whenever he breaks into security systems and whatnot. In fact, a large number of white hat hackers are security experts themselves who want to push the boundaries of their own IT security ciphers and shields or even penetration testers specifically hired to test out how vulnerable or impenetrable (at the time) a present protective setup currently is. A white hat that does vulnerability assessments and penetration tests is also known as an ethical hacker.

White Hat:  hackers who hack into security systems , and exploit bugs then report them to the owner without using that for any criminal activates.

Black Hat: hackers who hacks systems and exploit bugs without reporting them, instead they use that to preform cyber criminal activities

Gray Hat: hackers who try to act like white hat hackers, but end up using black hat methods . they are not as bad as the back hat and not as good as the white hat , they are kinda in the middle.
