According to psychologist Marc Rogers, there are four important groups of hackers. "Newbies" have access to hacker tools and programs, but are mostly without the knowledge and skills to write programs themselves. "Cyberpunks" have more knowledge than newbies and are smarter about their activities, but they also have a reputation for bragging beyond their actual accomplishments. "Coders" are serious hackers who write the programs that fellow hackers use to break into computer systems. "Cyber terrorists" break into network systems for profit, often participating in industrial sabotage or other lucrative illicit activities [source: Knittel and Soto].
