Nothing annoys me more than hearing the term “hacker” used as a synonym for “criminal”. I can actually accept it from people who do something else in life. It really bothers me when this abuse comes from people who say they are cyber security professionals.
I understand that in recent years everyone has become cyber security experts. Those who were previously blockchain experts, before big data experts and even before one of the many trends that have plagued IT. In many cases, the place of many of these would have been a nice industrial fryer for chips in a fast food restaurant.
“I know that I know nothing”, having quoted Socrates, I can admit that I am not the right person to explain what a hacker is, so I report the Manifesto.

If you don’t work in IT and you don’t know it, it’s not serious.
If you work in IT and you don’t know it, it’s serious.
If you work in cyber security and you don’t know it, for me mayonnaise and ketchup 😉
Being a hacker means facing life with passion and living the passion without limits. This does not mean harming others. For this reason a hacker is not a criminal. He can be if he harms others, but in doing so he becomes a criminal and must be considered as such.
Another thing: let’s be serious, “ethical hacker” is funny, it smacks of an elderly “script kiddie”!
