What Are Ethical Hackers?
There’s an issue with how some people define the word “hacker.” For some, it’s a word synonymous with “cybercriminal,” but not in the infosec community.

You can think of it like having an annoying party-crasher at your pool party who decides to stick around uninvited, hiding out somewhere and using all of your stuff.
