Are all hackers, crackers, etc. bad people?
Of course not. Be thankful there are nice hackers and crackers that wish to continuously test and try to break the security tools available for your protection. Do you think bad people who find exploits, want those exploits to be widely known or to be fixed? No, they want to use such things to their benefit. “White Hats” WANT to find vulnerabilities so fixes can be created. Privacy advocates wish to ensure that their privacy is ALWAYS protected so they are also working all the time to ensure any vulnerabilities are found and fixed. Security is like a chess game… move/counter move. Hopefully the “White Hats” can always counter every harmful gambit that “Black Hats” can use against you.
