You’re probably already familiar with the word hacker, but what does it really mean? well, according to Wikipedia:
A hacker is someone who seeks and exploits weaknesses in a computer system or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge or enjoyment.
Basically, hacking is all about exploiting weaknesses of someone else, but unlike the real world where exploiting someone else requires revealing yourself, here you have the chance to stay totally anonymous if you know what you’re doing.
