What Is a Computer Hacker?

A computer hacker is someone who uses flaws and oversights in a computer's security system to break into another machine. Motivations range from ideological reasons to the thrill of breaking into a complicated system. In the past, hacking has been used to hassle an intended victim, steal information or spread viruses. Non-malicious hackers say they are just curious how different computers and programs work.

History

The name "hacker" became popular in the 1960s. A counter-culture group called the Yippies broke into computers as part of their anti-authoritarian policy.

Characteristics of a Hacker

Most hackers are driven by the curiosity to about how different systems and programs work. Besides creating malicious software, hackers also created patches, sections of code or programs designed to fix flaws in existing systems.

Subgroups

There are different subgroups of hackers, each named to indicate attitudes and morals. For example, white hat hackers do not break into systems for malicious purposes, while black hat hackers subvert security for criminal reasons, such as stealing credit card information or vandalism.

Methods

Hackers work by collecting information on the intended target, figuring out the best plan of attack and then exploiting vulnerabilities in the system. Programs such as Trojan horses and worms are designed and used by hackers to get access to computers.

Famous Ties

Hackers are prominent characters in the books by William Gibson and have been major characters in films such as Enemy of the State and WarGames.
