Hackers can be classified into several color hats based on their work/ attitude.
Types of Hackers
Script Kiddies – They are beginners, absolutely dangerous, they are not aware of what they are doing and what will be the consequences. They simply copy code from the internet and use it as a virus or an SQL attack or something else.
Black Hat – Also known as Crackers, these are the men and women you hear about in the news. They find banks or other companies with weak security and steal money or credit card information. The surprising truth about their methods of attack is that they often use common hacking practices they learned early on.White Hat – They are experts, knows about nooks and corners of hacking, strong programmers, they are also known as ethical hackers, White Hat hackers are the good guys of the hacker world. They’ll help you remove a virus or do Pen-Test a company. Most White Hat hackers are certified to pursue a career in hacking. The most popular certification is the CEH (Certified Ethical Hacker) from the EC-Council.
Gray Hat – They are either black or white hat it depends on their work. Gray Hat hackers don’t steal money or information (although, sometimes they deface a website or two), yet they don’t help people for good (but, they could if they wanted to).
Green Hat – In hacker’s world they are the hacker “noobs,” but unlike Script Kiddies, they care about hacking and strive to become full-blown hackers. They’re often flamed by the hacker community for asking many basic questions. When their questions are answered, they’ll listen with the intent and curiosity of a child listening to family stories. Anyone who started to learn hacking seriously are of green hat.
Red Hat – These are the vigilantes of the hacker world. They’re like both White Hats and Black Hats, but these folks are downright SCARY to those who have ever tried so much as PenTest. Instead of reporting the malicious hacker, they shut him/her down by uploading viruses, DoSing and accessing his/her computer to destroy it from the inside out. They leverage multiple aggressive methods that might force a cracker to need a new computer. Simply they are the Cyber-psychopaths.
Blue Hat – If a Script Kiddie took revenge, he/she might become a Blue Hat. Blue Hat hackers will seek vengeance on those who’ve them angry. Most Blue Hats are n00bz, but like the Script Kiddies, they have no desire to learn.
