Crackers AKA Hackers

Hackers also known as Crackers

EXCERPT:
In common usage, a cracker is a person who breaks into computers, but does no harm, usually for fun or just the challenge.[1] The subculture that has evolved around crackers is often referred to as the computer underground but is now an open community. crackers are people who are motivated by curiosity and adventurer's spirit.[2]

Other uses of the word cracker exist that are not related to computer security (computer programmer and home computer hobbyists), but these are rarely used by the mainstream media because of the common stereotype that is in TV and movies. Some would argue that the people that are now considered crackers are not crackers, as before the media described the person who breaks into computers as a cracker there was a cracker community. This group was a community of people who had a large interest in computer programming, often sharing, without restrictions, the source code for the software they wrote. These people now refer to the cyber-criminal crackers as "crackers"[3].
