Word Origin & History

crack
O.E. cracian "make a sharp noise," from P.Gmc. *krakojan, probably onomatopoeic. The noun meaning "split, opening," is 14c. Meaning "try, attempt" first attested 1836, probably a hunting metaphor, from slang sense of "fire a gun." Meaning "rock cocaine" is first attested 1985. Cracked "mentally unsound"
is 17c. (though the equivalent Gk. word was used in this sense by Aristophanes), while crack as in "top-notch, superior" is slang from 1793. Crackpot "pretentious, worthless person" dates from 1883. The superstition that it is bad luck to step on sidewalk cracks has been traced to c.1890.

cracker
mid-15c., "hard wafer," but the specific application to a thin, crisp biscuit is 1739. Cracker-barrel (adj.) "emblematic of down-home ways and views" is from 1877. Cracker, Southern U.S. derogatory term for "poor, white trash" (1766), is from mid-15c. crack "to boast" (e.g. not what it's cracked up to
be), originally a Scottish word. Especially of Georgians by 1808, though often extended to residents of northern Florida.
"I should explain to your Lordship what is meant by crackers; a name they have got from being great boasters; they are a lawless set of rascalls on the frontiers of Virginia, Maryland, the Carolinas and Georgia, who often change their places of abode." [1766, G. Cochrane]

cracker definition

jargon
An individual who attempts to gain unauthorised access to a computer system. These individuals are often malicious and have many means at their disposal for breaking into a system. The term was coined ca. 1985 by hackers in defence against journalistic misuse of "hacker". An earlier attempt to establish "worm" in this sense around 1981--82 on Usenet was largely a failure.
Use of both these neologisms reflects a strong revulsion against the theft and vandalism perpetrated by cracking rings. The neologism "cracker" in this sense may have been influenced not so much by the term "safe-cracker" as by the non-jargon term "cracker", which in Middle English meant an obnoxious person (e.g., "What cracker is this same that deafs our ears / With this abundance of superfluous breath?" -- Shakespeare's King John, Act II, Scene I) and in modern colloquial American English survives as a barely gentler synonym for "white trash".
While it is expected that any real hacker will have done some playful cracking and knows many of the basic techniques, anyone past larval stage is expected to have outgrown the desire to do so except for immediate practical reasons (for example, if it's necessary to get around some security in order to get some work done).
Contrary to widespread myth, cracking does not usually involve some mysterious leap of hackerly brilliance, but rather persistence and the dogged repetition of a handful of fairly well-known tricks that exploit common weaknesses in the security of target systems. Accordingly, most crackers are only mediocre hackers.
Thus, there is far less overlap between hackerdom and crackerdom than the mundane reader misled by sensationalistic journalism might expect. Crackers tend to gather in small, tight-knit, very secretive groups that have little overlap with the huge, open hacker poly-culture; though crackers often like to describe *themselves* as hackers, most true hackers consider them a separate and lower form of life, little better than virus writers. Ethical considerations aside, hackers figure that anyone who can't imagine a more interesting way to play with their computers than breaking into someone else's has to be pretty losing.
See also Computer Emergency Response Team, dark-side hacker, hacker ethic, phreaking, samurai, Trojan horse.
