Black Hat Hacker

Black Hat Hackers, who may also be known as Crackers, Hackers, who specialise in unathorized penetration of information systems, They may use computers to attack systems for profit, or just for fun, but such penetration often involves modification or destruction of data, and is done without authorization. They also may distribute computer viruses, Internet Worms, and deliver spam through the use of botnets. In a security context, a hacker is someone involved in computer security/insecurity, specializing in the discovery of exploits in systems (for exploitation or prevention), or in obtaining or preventing unauthorized access to systems through skills, tactics and detailed knowledge. In the most common general form of this usage, "hacker" refers to a black-hat hacker (a malicious or criminal hacker). There are also ethical hackers (more commonly referred to as white hats), and those more ethically ambiguous (grey hats). To disambiguate the term hacker, often cracker is used instead, referring either to computer security hacker culture as a whole to demarcate it from the academic hacker culture or specifically to make a distinction within the computer security context between black-hat hackers and the more ethically positive hackers (commonly known as the white-hat hackers). The context of computer security hacking forms a subculture which is often referred to as the network hacker subculture or simply the computer underground. According to its adherents, cultural values center around the idea of creative and extraordinary computer usage. Proponents claim to be motivated by artistic and political ends, but are often unconcerned about the use of criminal means to achieve them. Sometimes hackers can be dangerous. A black hat hacker is someone who subverts computer security without authorization or who uses technology (usually a computer or the Internet) for terrorism, vandalism (malicious destruction), credit card fraud, identity theft, intellectual property theft, or many other types of crime. This can mean taking control of a remote computer through a network, or software cracking.
