Hacker definition controversy

The terms hacker and hack are marked by contrasting positive and negative connotations. Computer programmers often use the words hacking and hacker to express admiration for the work of a skilled software developer, but may also use them in a negative sense to describe the production of inelegant kludges. Some frown upon using hacking as a synonym for security cracking -- in distinct contrast to the larger world, in which the word hacker is typically used to describe someone who "hacks into" a system by evading or disabling security measures.

[edit]Controversy and ambiguity

While "hack" was originally more used as a verb for "messing about" with (e.g. "I hack around with computers"), the meaning of the term has shifted over the decades since it first came into use in a computer context. As usage has spread more widely, the primary meaning of newer users of the word has shifted to one which conflicts with the original primary emphasis.

Currently, "hacker" is used in two main ways, one pejorative and one complimentary. In popular usage and in the media, it most often refers to computer intruders or criminals, with associated pejorative connotations. (For example, "An Internet 'hacker' broke through state government security systems in March.") In the computing community, the primary meaning is a complimentary description for a particularly brilliant programmer or technical expert. (For example, "Linus Torvalds, the creator of Linux, is considered by some to be a hacker.") A large segment of the technical community insist the latter is the "correct" usage of the word (see the Jargon Filedefinition below).

The mainstream media's current usage of the term may be traced back to the early 1980s (see History). When the term was introduced to wider society by the mainstream media in 1983, even those in the computer community referred to computer intrusion as "hacking", although not as the exclusive use of that word. In reaction to the increasing media use of the term exclusively with the criminal connotation, the computer community began to differentiate their terminology. Several alternative terms such as "black hat" and "cracker" were coined in an effort to distinguish between those performing criminal activities, and those whose activities were the legal ones referred to more frequently in the historical use of the term "hack". Analogous terms such as "white hats" and "gray hats" developed as a result. However, since network news use of the term pertained primarily to the criminal activities despite this attempt by the technical community to preserve and distinguish the original meaning, the mainstream media and general public continue to describe computer criminals with all levels of technical sophistication as "hackers" and does not generally make use of the word in any of its non-criminal connotations.

As a result of this difference, the definition is the subject of heated controversy. The wider dominance of the pejorative connotation is resented by many who object to the term being taken from their cultural jargon and used negatively,^[7] including those who have historically preferred to self-identify as hackers. Many advocate using the more recent and nuanced alternate terms when describing criminals and others who negatively take advantage of security flaws in software and hardware. Others prefer to follow common popular usage, arguing that the positive form is confusing and unlikely to become widespread in the general public. A minority still stubbornly use the term in both original senses despite the controversy, leaving context to clarify (or leave ambiguous) which meaning is intended. It is noteworthy, however, that the positive definition of hacker was widely used as the predominant form for many years before the negative definition was popularized.

"Hacker" can therefore be seen as a shibboleth, identifying those who use the technically-oriented sense (as opposed to the exclusively intrusion-oriented sense) as members of the computing community.

A possible middle ground position has been suggested, based on the observation that "hacking" describes a collection of skills which are used by hackers of both descriptions for differing reasons. The analogy is made to locksmithing, specifically picking locks, which — aside from its being a skill with a fairly high tropism to 'classic' hacking — is a skill which can be used for good or evil. The primary weakness of this analogy is the inclusion of script kiddies in the popular usage of "hacker", despite the lack of an underlying skill and knowledge base.

Fred Shapiro thinks that "the common theory that 'hacker' originally was a benign term and the malicious connotations of the word were a later perversion is untrue." He found out that the malicious connotations were present at MIT in 1963 already and then referred to unauthorized users of the telephone network^[8] (which are also called phreakers).

[edit]History

• 1950s: amateur radio enthusiasts defined the term hacking as creatively tinkering to improve performance.
• 1959: hack is defined in MIT's Tech Model Railroad Club Dictionary as "1) an article or project without constructive end; 2) a project undertaken on bad self-advice; 3) an entropy booster; 4) to produce, or attempt to produce, a hack(3)." hacker is defined as "one who hacks, or makes them." Much of the TMRC's jargon is later imported into early computing culture.
• 1963: The first recorded reference to hackers in the computer sense is made in The Tech (MIT Student Magazine).^[9]
• 1972: Stewart Brand publishes "S P A C E W A R: Fanatic Life and Symbolic Death Among the Computer Bums" in Rolling Stone, an early piece describing computer culture. In it, Alan Kay is quoted as saying "A true hacker is not a group person. He's a person who loves to stay up all night, he and the machine in a love-hate relationship... They're kids who tended to be brilliant but not very interested in conventional goals[...] It's a term of derision and also the ultimate compliment."
• 1980: The August issue of Psychology Today prints (with commentary by Philip Zimbardo) "The Hacker Papers", an excerpt from a Stanford Bulletin Board discussion on the addictive nature of computer use.
• 1982: In the film TRON, Kevin Flynn (Jeff Bridges) describes his intentions to break into ENCOM's computer system, saying "I've been doing a little hacking here". CLU is the software he uses for this.
• 1983: The movie WarGames, featuring a computer intrusion into NORAD, is released. A gang of 6 teenagers is caught breaking into dozens of computer systems, including that of Los Alamos National Laboratory.^[10] Newsweek features the cover story "Beware: Hackers at play."^[11] First Usenet post on the use of the termhacker in the media (CBS News) to mean computer criminal.^[12] Pressured by media coverage of computer intrusions, Congress begins work on new laws for computer security.^[13]

• 1988: Stalking the Wily Hacker, an article by Clifford Stoll appears in the May 1988 issue of the Communications of the ACM and uses the term hacker in the sense of a computer criminal. Later that year, the release by Robert Tappan Morris, Jr. of the so-called Morris worm provoked the popular media to spread this usage.
• 1989: The Cuckoo's Egg by Clifford Stoll is published, and its popularity further entrenches the term in the public's consciousness.
• 2008: Global movement of Hackerspaces emerges. These labs are technological, cultural and social creative places enabling hackers to develop projects together, code, create open source projects or hardware designs.

[edit]Contemporary use

The modern, computer-related use of the term is considered likely rooted in the goings on at the Massachusetts Institute of Technology (MIT) in the 1960s, long before computers became common; the word "hack" was local slang which had a large number of related meanings. One was a simple, but often inelegant, solution to a problem. It also meant any clever prank perpetrated by MIT students; logically, the perpetrator was a hacker. To this day the terms hack and hacker are used in several ways at MIT, without necessarily referring to computers. When MIT students surreptitiously put a fake police car atop the dome on MIT's Building 10, that was a hack, and the students involved were therefore hackers. Another type of hacker — one who explores undocumented or unauthorized areas in buildings — is now called a reality hacker or urban spelunker.

The term was fused with computers when members of the Tech Model Railroad Club started working with a Digital Equipment Corporation PDP-1 computer and applied local model railroad slang to computers.

The earliest known use of the term in this manner is from the 20 November 1963 issue of The Tech, the student paper of MIT:

Many telephone services have been curtailed because of so-called hackers, according to Prof. Carlton Tucker, administrator of the Institute phone system. […] The hackers have accomplished such things as tying up all the tie-lines between Harvard and MIT, or making long-distance calls by charging them to a local radar installation. One method involved connecting the PDP-1 computer to the phone system to search the lines until a dial tone, indicating an outside line, was found. […] Because of the 'hacking', the majority of the MIT phones are 'trapped'.

Originally, the term "hack" was applied almost exclusively to programming or electrical engineering, but it has come to be used in some circles for almost any type of clever circumvention, in phrases such as "hack the media", "hack your brain" and "hack your reputation".

[edit]Negative usage in engineering

Another meaning of the term "hack", similar to kludge and distinct from both the positive and security-related meanings discussed above, derives from the everyday English sense "to cut or shape by or as if by crude or ruthless strokes" [Merriam-Webster]. In other words to "hack" at an original creation, as if with an axe, is to force-fit it into being usable for a task not intended by the original creator, and a "hacker" would be someone who does this habitually. (The original creator and the hacker may be the same person.)

This usage is common in both programming^[14] and engineering. In programming, hacking in this sense appears to be tolerated and seen as a necessary compromise in many situations. In non-software engineering, the culture is less tolerant of unmaintainable solutions, even when intended to be temporary, and describing someone as a "hacker" might imply that they lack professionalism. In this sense, the term has no real positive connotations, except for the idea that the hacker is capable of doing modifications that allow a system to work in the short term, and so has some sort of marketable skills. There is always, however, the understanding that a more skillful, or technical, logician could have produced successful modifications that would not be considered a "hack-job".

The definition is similar to other, non-computer based, uses of the term "hack-job". For instance, a professional modification of a production sports car into a racing machine would not be considered a hack-job, but a cobbled together backyard mechanic's result could be. Even though the outcome of a race of the two machines could not be assumed, a quick inspection would instantly reveal the difference in the level of professionalism of the designers.
