White hat hackers:

If an individual uncovers a vulnerability and exploits it with authorization, he is considered a white hat.

Gray hat hackers:

                If a different person uncovers a vulnerability, does not illegally exploit it or tell others how to do it, but works with the vendor—this person gets the label of gray hat.

Black hat hackers:
                   If an individual uncovers a vulnerability and illegally exploits it and/or tells others how to carry out this activity, he is considered a black hat.
