especially in computing slang, where it refers to a hacker who breaks into networks or computers, or creates computer viruses.
Black Hat Hackers (also called "crackers"), are hackers who specialize in unauthorized penetration. They may use computers to attack systems for profit, for fun, or for political motivations or as a part of a social cause. Such penetration often involves modification and/or erasing of data, and is done without authorization and hence they should not be confused with “ethical hackers” (see white hat hacker).
They also may distribute computer viruses, Internet worms, and deliver spam through the use of botnets. The term may also refer to hackers who crack software to remove copy restriction methods: copy prevention, trial/demo version, serial number, hardware key, date checks, CD check (NO-CD) or software annoyances like nag screens and adware.
Some of the blackhat SEO tactics include: keyword stuffing, hidden text and links, doorway and cloaked pages, link farming and blog comment spam.
