The term hacker has always been misused and is always used to refer to someone who will steal your bank accounts or "hack" your social networks, I will try to explain the difference between hacker, cracker or lick.
HACKER.
A hacker is a person with advanced knowledge of computer security, networks, programming, etc.
This person enjoys acquiring new knowledge in addition to dedicating himself to creating safe and functional systems, although this type of computer scientist has the necessary experience to break systems, he would only do it to improve the security of these.
CRACKER
This term was born from crack which means to break, CRACKERS are considered cyber-criminals who have the knowledge to invade systems, decipher encryption algorithms and steal information, generally they do it only because of the challenge that this implies, but some of them can do it for profit or protest.
LICK
The Lamers are the most hated group of computer scientists, they are usually individuals with a desire to do Hacking, but who lack any knowledge.
They are "computer scientists" who do not have the knowledge to build their own tools so they dedicate themselves to using those of others, this makes them a very dangerous group because they are always trying to break systems using software which they do not fully understand.
