So, this is a thing that I have been wondering for a while. Where white-hat ends and grey-hat begins?
For instance, imagine that your objective, while hacking, is to find criminals (drug-dealers, paedophiles, sex-offenders, you name it). Of course, if you are operating alone (i.e. without the help of the law) what you are doing is illegal, even if you are doing it for the right reasons. Is this white-hat, because illegal, or grey-hat? Because, for me, grey-hat is when you do it to gain something in return. In this cause, you are doing it for the greater good. Does anyone has an answer for this?
